Which telescope to buy?

Below are some of the telescopes I've used in recent years, ranging from ~30 -3000 dollars. (shortened for YTs character limits) Price $35 76mm reflector dobsonian mounted (Celestron Firstscope) Weight ~ 1kg (a couple of pounds) Setup time ~0 East of Transport 1 Short focal length- wide angle field of view. Finder not really necessary. Ultra cheap, good views of Moon, Jupiter Venus, rings of Saturn, bright, wide separation double stars, and brighter deep sky objects such as M13. I was not particularly impressed with the optics on mine, but for 35 bucks, you cant complain too much! Price $200 90mm Maksutov-Cassegrain, dobsonian mount (Orion Apex) Weight ~ 1kg (a couple of pounds) Setup time ~0 East of Transport 1 Longer focal length means smaller field of view for comparable eye pieces. I was impressed with this scope on the planets. It vastly outperforms the Firstscope on optics. The scope comes off the dobsonian mount on a quick release and can be mounted as a spotter scope (the main reason I got it). The dobsonian mount here (one arm) is exactly the same as the mount for the Firstscope. These are sort of the poor mans refractor. Great views of Moon and all the bright planets. Picked out Titan (brightest moon of saturn) with ease. I got this telescope for two reasons, firstly for outreach, in that you can just grab it and point it in seconds, zero setup time. Secondly I can mount it piggyback on the CPC11 (see below) and use it as a spotting/ guide scope. The Maksutov has the 'nice' feature that its a closed tube(helps keep dust out). The Mak. will have the edge on planets/ guidescope etc due to its longer focal length, but the Newtonian will be more all around bang for the buck. Price $600 10in Newtonian reflector, dobsonian mount (Celestron Starhopper) Weight ~ 15kg (~30lbs) Setup time ~10 mins to carry parts outside, 10 mins + cool down. East of Transport: Telescope is about the size of a small child (although not that heavy). It is big and awkward. Difficult to handle for the small. Almost the biggest telescope you can fit in a compact car (the reason I got it). The long open optical train requires periodic alignment (columniation) if it is frequently transported. Powerful deep-sky scope. Near zero photographic potential, but fantastic views of nebula, globular clusters and galaxies. Great scope for planets too. At this size the moon is getting too bright to look at for any length of time. Like most big newtonians, short focal ratio, which pragmatically means you get quite wide angle views. Again well suited to deep sky observing. Price $1500 90mm (3.5in) Stellarvue apochromat, -no mount, tube only (Apo Triplet) Weight ~ 4kg (~8lbs) East of Transport: The telescope is small and easy to transport. Comes with a bag that will go on an airplane as hand baggage. Worth the price for the aperture? Probably not unless you are in a fairly specific niche. This makes a great wide angle lenses for guided photography. As a guidescope its focal length is kind of short. That basically means the field of view for a given eye piece is wide. You need a very short focal length eye piece to get good magnification. I found myself using a 4mm eyepiece to look at planets, and even at that the image was small. As a finder scope though, that wide field is great. The other thing that these scope gives is absolutely beautiful stellar images. The stars just fall into incredible pin pricks. Beautiful contrasty flat views. I found the use of the short focal length eyepieces annoying for planetary use. Lacks the light gathering for versatility as a deep sky instrument. I only really ever used this as a piggybacker for the CPC11 below. Price $2800 11in Schmidt Cassegrain, driven goto alt-az fork mount (CPC11) Weight ~ 30kg (~65lbs) and thats just the top section. Tripods another 15 kg I think. Setup time ~30 mins to carry parts outside and align, 20 mins + cool down. East of Transport: It will fit in a compact car. To carry the telescope any distance really isnt an option unless you are strong. The ergonomic design is very good though. I always found mounting up the scope a bit of a bitch. Aligning it is relatively easy as the scope mount has a GPS in it that means you dont have to plug in these numbers and the time. Alignment is quite easy. I found the scope slips relatively easily unless the clutches are done up very tight. The scope can carry quite a burden (although of course when the scope weights this much extra, it does need to be well balanced). At this level it is an excellent photographic platform. It yields amazing views of almost everything. It's photographic potential is probably as good as you can get from a portable platform. This is the instrument I used to do the full rotation of Jupiter, although there the primary limitation was the stability of the sky.

Meade LX200 Telescope - What can you see...

Telescope - Meade LX200 - what can you see with a 10" from Eastchurch on the Isle of Sheppey. Kent. UK. Also see "LX200 - Observatory" for more detail of how it works... All images by Peter Bruce Eastchurch Gap. This video sounded better with original Enya music but had to change due to copyright - shame. Images taken with Webcam, Cannon EOS, Starlight Xpress MX7C, Meade DSI 1 & DSI 3 & Astrovid camera's. I wish we could all "see" with our own eyes the pictures shown here but our eyes are not very sensitive at low light levels but what is importance is the fact you can see the sights with a modest set-up. And the night sky is God given and free to view - Best TV in the world...

Hubble Space Telescope - Better Than Ever!

Science & Reason on Facebook: http://tinyurl.com/ScienceReason The Hubble Space Telescope Is Back - Better Than Ever! Final Servicing Mission. --- Please subscribe to Science & Reason: • http://www.YouTube.com/Best0fScience • http://www.YouTube.com/ScienceMagazine • http://www.YouTube.com/ScienceTV • http://www.YouTube.com/FFreeThinker --- "Improved Hubble Shows Evidence of Dark Matter" • http://www.youtube.com/user/tdarnell#play/uploads/2/3wluv08tDhU • http://www.deepastronomy.com/ "When Hubble Opened its New Eyes" • http://www.youtube.com/AndromedasWake • http://www.youtube.com/watch?v=9bytNgT7l8k "The Hubble Space Telescope - Rebirth of an Icon (Hubblecast 30)" • http://www.youtube.com/ESOcast • http://www.youtube.com/watch?v=Hjy7YSIH-GI --- The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by the space shuttle in April 1990. It is named after the American astronomer Edwin Hubble. Although not the first space telescope, the Hubble is one of the largest and most versatile, and is well-known as both a vital research tool and a public relations boon for astronomy. The HST is a collaboration between NASA and the European Space Agency, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope. Space telescopes were proposed as early as 1923. The Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, scientists found that the main mirror had been ground incorrectly, severely compromising the telescope's capabilities. However, after a servicing mission in 1993, the telescope was restored to its intended quality. Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely sharp images with almost no background light. Hubble's Ultra Deep Field image, for instance, is the most detailed visible-light image ever made of the universe's most distant objects. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe. The Hubble is the only telescope ever designed to be serviced in space by astronauts. There have been five servicing missions, the last occurring in May 2009. Servicing Mission 1 took place in December 1993 when Hubble's imaging flaw was corrected. Servicing missions 2, 3A, and 3B repaired various sub-systems and replaced many of the observing instruments with more modern and capable versions. However, following the 2003 Space Shuttle Columbia accident, the fifth servicing mission was canceled on safety grounds. After spirited public discussion, NASA reconsidered this decision, and administrator Mike Griffin approved one final Hubble servicing mission. STS-125 was launched in May 2009, and installed two new instruments and made numerous repairs. The latest servicing should allow the telescope to function until at least 2014, when its successor, the James Webb Space Telescope (JWST), is due to be launched. The JWST will be far superior to Hubble for many astronomical research programs, but will only observe in infrared, so it will complement (not replace) Hubble's ability to observe in the visible and ultraviolet parts of the spectrum. • http://en.wikipedia.org/wiki/Hubble_Space_Telescope .

Giant Solar Tornado Makes a Film Debut

The only thing more terrifying than a giant twister on Earth is one on the face of the sun. A monstrous tornado has been observed erupting on our star, and its numbers are staggering. So big it could swallow five Earths in one gulp, the swirling vortex observed last September and presented at this week's National Astronomy Meeting in England grew to a height of 125,000 miles, about half the distance between Earth and the moon. The temperature of the plume of superheated gas measured between 90,000 and 3.6 million degrees Fahrenheit and was accelerated to speeds approaching 186,000 miles per hour. Discovered by NASA's Solar Dynamic Observatory, this Master Blaster is thought to be the first Solar Tornado ever filmed, and may help us understand the kinds of large particle eruptions that recently came flying at us from the ball of gas. As our local star approaches Solar Max, the peak activity of an 11-year cycle, 2012 is shaping up to be one spectacular year for space weather.

5-times size of Earth: Giant solar tornado caught in rare NASA tape (VIDEO).mp4

For more exclusive information on UFOs, visit: http://erigia.blogspot.com/2012/05/les-theories-du-complot-revendication.html 5 fois la taille de la Terre: Géant tornade solaire pris dans la NASA cassette rare (VIDEO): Une tornade géante solaire - cinq fois le diamètre de la Terre - tourbillonnant à la vitesse incroyable de certains mph 186000 a été capté sur vidéo par l'Observatoire de la NASA Solar Dynamics. C'est la première fois un géant solaire twister a été capturé sur vidéo. Tornades solaires, connus sous le nom des protubérances solaires, sont façonnées par le champ magnétique du soleil et se produisent souvent pendant les éjections de masse coronale - explosions énormes de plasma solaire. La vitesse de gaz tourbillonnant solaires peut parfois atteindre plusieurs milliers de miles par heure. Cette tornade 124 000-mile de haut a été filmé le 25 Septembre 2011, mais la vidéo n'a été rendu public lors de la réunion national d'astronomie à Manchester (Royaume-Uni) le jeudi. Xing Li, un astronome de l'Université d'Aberystwyth au Pays de Galles, estime que le constat est un "vrai petit bijou d'un événement de frapper l'imagination, et il est un bon moyen d'étudier les structures magnétiques dans l'atmosphère du soleil." Les scientifiques pensent que l'étude de tornades solaires permettra de comprendre les causes des tempêtes de l'espace en général, qui est encore l'un des grands mystères de notre système solaire. ---------------------------------------------------------------------------------------------- A giant solar tornado - five times the Earth's diameter - swirling at incredible speed of some 186,000 mph has been captured on video by NASA's Solar Dynamics Observatory. ­This is the first time a giant solar twister has been caught on video. Solar tornadoes, known as solar prominences, are shaped by the sun's magnetic field and often occur during coronal mass ejections -- huge explosions of solar plasma. The speed of swirling solar gases can sometimes reach several thousand miles per hour. This 124,000-mile-tall tornado was filmed on September 25, 2011, but the video was only released to the public at the National Astronomy Meeting in Manchester (UK) on Thursday. Xing Li, an astronomer at Aberystwyth University in Wales, believes the finding is a "real gem of an event to fire the imagination, and it is a good way to study magnetic structures in the sun's atmosphere." Scientists believe that study of solar tornadoes will help understand the causes of space storms in general, which is still one of the great mysteries of our solar system.

Tornado's Whirl On Sun's Surface 2012

Astronomers were given a spectacular show on the sun as a "solar tornado" made its way across the surface. The footage, captured over a 30-hour period by NASA's Solar Dynamics Observatory. captures the slow-moving solar flares as they danced across the surface. The large solar "tornadoes" blasted across the surface of the sun on February 7 and 8, and are formed by the magnetic field created by the star. "An active region rotating into view provides a bright backdrop to the gyrating streams of plasma," SDO mission scientists were quoted as saying on space.com. "The particles are being pulled this way and that by competing magnetic forces. They are tracking along strands of magnetic field lines."

Helmut Jerjen: Tales of stars and stellar systems - part one

In the first of this two-part video Dr Helmut Jerjen tells 'Tales of stars and stellar systems' . The event is part of Mount Stromlo's Centenary Celebrations. Astronomy has arguably had the single largest impact on the development of science, human society and culture over the past 10,000 years. On our journey through space and time we will explore the glorious life of our sun, learn how astrophysical knowledge acquired 100 years ago can help to solve the energy crisis on Earth today, and find out why we should rightfully call ourselves the children of the stars. The discovery of exoplanets is a regular topic in the international news. Dr Jerjen explains how astronomers measure the faint signal from these distant island worlds, show where our place in the Milky Way is, and disclose how the Universe grew a million times bigger on the night of October 6, 1923. Dr Jerjen is a member of academic staff at the Research School of Astronomy & Astrophysics (RSAA) at ANU. As a genuine multi-wavelength astrophysicist he has published over 100 articles in international journals covering topics in the areas of near-field cosmology, stellar populations, galaxy evolution and dark matter. He is the head of the Stromlo Milky Way Satellite Survey team that will make use of the new ANU SkyMapper Telescope to study dark-matter dominated dwarf galaxies in the halo of our Milky Way. Dr Jerjen is passionate about educating future generations of astrophysicists.

Kepler 22b New Planet Discovered Earth like Characteristics -- News Story

Kepler-22b New Planet With Earth-Like Characteristics Discovered In Habitable Zone thoughts NASA's Kepler Confirms Its First Planet in Habitable Zone of Sun-like Star: Kepler 22-b (5/12/2011) thoughts NASA's Kepler Mission Announces Latest Planetary Discovery thoughts This is amazing news according to reports NASA announced the discovery of Kepler-22b this is great the first planet the Kepler spacecraft has discovered in the habitable zone, an area with a distance from a star where temperatures will permit the existence of liquid water.Reports say the discovery of Kepler-22b which is 600 light-years away from Earth, brings scientists one step closer to finding a planet that could possibly harbor life Earth may not be the only one This is a major milestone on the road to finding Earth's twins Kepler's results continue to demonstrate the importance of NASA's science missions, which aim to answer some of the biggest questions about our place in the universe Kepler-22b has several Earth-like characteristics according to reports The new planet's temperature is around 72 degrees Fahrenheit and its radius is 2.4 times Earth's. The planet completely orbits its star, which is similar to our sun, every 290 days, just 75 days shy of an Earth year Reports say that the National Optical Astronomy Observatory announced the discovery of Kepler-21b, a new planet with a radius 1.6 times Earth's. But unlike Kepler-21b, which is only about 3.7 million miles away from its sun and is therefore a scorching 2,960 degrees Fahrenheit, Kepler-22b is about 79 million miles from its sun, coming in at a pleasant 72 degrees. it's not yet clear if Kepler-22b is composed or rock, gas or liquid according to reports. Scientists use the Kepler spacecraft to discover new planets by analyzing extremely faint dips in light from far-away stars. These "dips" occur each time the planet passes between the Kepler and its sun, therefore obstructing the star's light. In order for a planet to be confirmed, scientists must observe the celestial body orbit its sun three times according to sources Kepler-22B takes 290 days to orbit its sun, it took nearly three Earth years for scientists to confirm that it was a planet.

Space Odyssey: Voyage To The Planets 1 - BBC

Space Odyssey: Voyage To The Planets This two-part science fiction docu-drama examines the possibilities of a dangerous, manned space mission to explore the inner and outer planets of the Solar system. Five astronauts pilot the nuclear thermal rocket powered Pegasus spacecraft on a tour of the solar system. Their mission is a collaboration of the NASA, CSA, ESA and РКА space agencies and takes the crew to Venus, Mars, a close flyby of the Sun, Jupiter's moon Io and Europa, Saturn, Pluto, and the fictional Comet Yano-Moore. Most of the planetary destinations the crew reaches are followed by a manned landing there. Prior to the mission large tanks of hydrogen were deposited in stable orbits around the planets to allow the crew to refuel to have sufficient delta-v for the multi-year mission. The crew encounter many hardships and disappointments along the way. A Venus EVA that almost ends in disaster when the lander Orpheus encounters launch delays, the near-loss of the shield during the aerobrake in Jupiter's upper atmosphere (according to the first part of the miniseries) and the loss of samples from Jupiter's moon Io all test the crew's resolve. The most devastating blow comes when the ship's medical officer dies of solar radiation-induced lymphoma in Saturn orbit, forcing the crew to decide whether to continue the mission to Pluto, or abort and return to Earth. In the original British release, the crew decides to press on to Pluto, making history.

Planetary Science: Exploring The Solar System

Science & Reason on Facebook: http://tinyurl.com/ScienceReason Science@ESA (Episode 7): Planetary science - Exploring our backyard, the Solar System (Part 2) In this seventh episode of the Science@ESA vodcast series Rebecca Barnes continues to journey through the wonders of modern astronomy bringing us closer to home as we begin to explore the Solar System. We'll discover the scale and structure of the Solar System, find out why we explore it and introduce the missions launched on a quest to further investigate our local celestial neighbourhood. --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- Planetary science is the scientific study of planets (including Earth), moons, and planetary systems, in particular those of the Solar System and the processes that form them. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, originally growing from astronomy and earth science, but which now incorporates many disciplines, including planetary astronomy, planetary geology (together with geochemistry and geophysics), physical geography (geomorphology and cartography as applied to planets), atmospheric science, theoretical planetary science, and the study of extrasolar planets. Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology. There are interrelated observational and theoretical branches of planetary science. Observational research can involve a combination of space exploration, predominantly with robotic spacecraft missions using remote sensing, and comparative, experimental work in Earth-based laboratories. The theoretical component involves considerable computer simulation and mathematical modelling. Planetary scientists are generally located in the astronomy and physics or earth sciences departments of universities or research centres, though there are several purely planetary science institutes worldwide. There are several major conferences each year, and a wide range of peer-reviewed journals. • http://en.wikipedia.org/wiki/Planetary_science --- The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets - Mercury, Venus, Earth and Mars. Beyond Mars is the asteroid belt - a region populated by millions of rocky objects. These are left-overs from the formation of the planets, 4.5 billion years ago. On the far side of the asteroid belt are the four gas giants - Jupiter, Saturn, Uranus and Neptune. These planets are much bigger than Earth, but very lightweight for their size. They are mostly made of hydrogen and helium. Until recently, the furthest known planet was an icy world called Pluto. However, Pluto is dwarfed by Earth's Moon and many astronomers think it is too small to be called a true planet. An object named Eris, which is at least as big as Pluto, was discovered very far from the Sun in 2005. More than 1,000 icy worlds such as Eris have been discovered beyond Pluto in recent years. These are called Kuiper Belt Objects. In 2006, the International Astronomical Union decided that Pluto and Eris must be classed as "dwarf planets". Even further out are the comets of the Oort Cloud. These are so far away that they are invisible in even the largest telescopes. Every so often one of these comets is disturbed and heads towards the Sun. It then becomes visible in the night sky. • http://sci.esa.int/science-e/www/area/index.cfm?fareaid=7 .

PREVIEW: Alien Planets & Eyeball Earths

Music by Zero Project. The hunt for planets beyond our solar system has reached a fever pitch. With some 500 planets revealed by ground telescopes, now, the ultimate planet finder, the Kepler space telescope, has released a tsunami of data. Among over a thousand new planet prospects are 200 multi-planet solar systems and 58 worlds in life-friendly orbits. They're all within a narrow window on the sky the size of your hand. That's why this may be the tip of the iceberg in a galaxy that's literally crawling with planets. Scientists are now beginning to envision what these worlds are like, with atmospheres, oceans, geological history. In the process, they are redefining what a planet might need to spawn life.

Big New ExoPlanet Haul

From EsoCast in 1080p, comes the announcement of a rash of new planet discoveries. Astronomers using ESO's leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular orbits within the habitable zone around its star. Among the new planets just announced by scientists, sixteen are super-Earths - rocky planets up to ten times as massive as Earth. This is the largest number of such planets ever announced at one time. A planet in orbit causes its star to regularly move backwards and forwards as seen from Earth. This creates a tiny shift of the star's spectrum that can be measured with an extremely sensitive spectrograph such as HARPS. In their quest to find a rocky planet that could harbor life, astronomers are now pushing HARPS even further. They have selected ten well-studied nearby stars similar to our Sun. Earlier observations showed that these were ideal stars to examine for even less massive planets. After two years of work, the team has found five light super-Earths around three of the stars. These planets are very good candidates for future observations looking for evidence of life. One of the newly found planets, named HD 85512 b, orbits inside the habitable zone. This is the narrow area around a star where water can exist in liquid form. Astronomers estimate that liquid water could possibly be present on this planet if it is a rocky world that has more than 50% cloud cover. By looking carefully at the results from the first 8 years of HARPS observations, the team has found that around 40% of stars similar to the Sun harbor at least one planet lighter than Saturn. These new results lead astronomers to believe that they could soon find more super-Earths in the habitable zones of their stars with HARPS. These planets will be great targets for powerful future telescopes to try to study their atmospheres looking for evidence of life. Thanks to HARPS, the search for another Earth elsewhere in the galaxy is picking up pace!

Fifty New Exoplanets Discovered by HARPS

Astronomers using ESO's leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular seems to orbit in the habitable zone around its star. In this video news release we look at how astronomers discover these distant worlds and what the future may hold for finding rocky worlds like the Earth that may support life.

ESO 20 Richest eXoPlanetary System Ever [HD] Discovered by HARPS (not HAARP!)

~credits video: http://youtube.com/ESOobservatory Astronomers using ESO instruments have discovered a remarkable extrasolar planetary system that has some striking similarities to our own Solar System. At least five planets are orbiting the Sun-like star HD 10180, and the regular pattern of their orbits is similar to that observed for our neighbouring planets. One of the new extrasolar worlds could be only 1.4 times the mass of the Earth, making it the least massive exoplanet ever found. This video podcast explains how these faraway planets were detected and exactly what we know about them. Astronomers using ESO's world-leading HARPS instrument have discovered a planetary system containing at least five planets, orbiting the Sun-like star HD 10180. The researchers also believe the system has two other planets, one of which would have the lowest mass ever found, making the system similar to our own Solar System in terms of the number of planets. Furthermore, the scientists find that the location of the planets follows a regular pattern, as also seen in our own Solar System The team of astronomers used the HARPS spectrograph, attached to ESO's 3.6-metre telescope at La Silla, Chile. HARPS is an instrument with unrivalled stability and great precision, and the world's most successful exoplanet hunter. The astronomers, led by Christophe Lovis from the Geneva Observatory, studied the Sun-like star HD 10180 over a period of six years! This star is located 127 light-years away in the southern constellation Hydrus ("the Male Water Snake"). Thanks to the 190 individual HARPS measurements, the astronomers detected the wobbles of the star caused by five or more planets. The five strongest signals correspond to planets with Neptune-like masses — between 13 and 25 Earth masses — which orbit the star in between 6 to 600 days. The astronomers have also strong reason to believe that two other planets are present. One would be a Saturn-like planet orbiting in 2200 days. The other, having a mass of only about 1.4 times that of the Earth would be the least massive exoplanet ever discovered. This suspected planet is very close to its host star and so it is likely to be very hot. One 'year' on this planet lasts only 1.18 Earth-days! The newly discovered Solar System is unique in several respects. First of all, with at least five Neptune-like planets lying within a distance equivalent to the orbit of Mars, this system is more populated than our own Solar System in its inner region, and has many more massive planets there. Furthermore, the system probably has no Jupiter-like gas giant. In addition, all the planets seem to have almost circular orbits. Dynamical studies of the new system reveal complex interactions between planets and give us insights into its long-term evolution. Using the new discovery as well as data for other planetary systems, the astronomers discovered that the locations of the planets seem to follow a regular pattern — similar to the "Titius-Bode" law that exists in our Solar System. This could be a general signature of how planetary systems form. Another important result is that all very massive planetary systems are found around massive and metal-rich stars, while the four lowest-mass systems are found around lower-mass and metal-poor stars. These properties confirm current theoretical models. There is no doubt that this remarkable discovery highlights the fact that we are now entering a new era in exoplanet science: the study of complex planetary systems and not just of individual planets!! And with HARPS, European astronomers will be a driving force behind this transition. --- ESOcast is produced by ESO, the European Southern Observatory.
