NASA's Kepler spacecraft is discovering a veritable avalanche of alien worlds. As the numbers mount, it seems to be just a matter of time before Kepler finds what astronomers are really looking for: an Earth-like planet orbiting its star in the "Goldilocks zone".
The Kepler mission's science team announced its latest finding at a press conference on Monday, Dec. 5, 2011. The team announced the confirmation of Kepler-22b, its first planet found in the "habitable zone," the region where liquid water could exist on a planet's surface. The planet is about 2.4 times the radius of Earth, orbits around a star similar to our sun and is located 600 light-years away. Scientists don't yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets. The planet's host star belongs to the same class as our sun, called G-type, although it is slightly smaller and cooler.
Kepler also has discovered 1,094 new planet candidates, nearly doubling its previously known count. Since the last catalog was released in February, the number of planet candidates identified by Kepler has increased by 89 percent and now totals 2,326. Of these, 207 are approximately Earth-size, 680 are super Earth-size, 1,181 are Neptune-size, 203 are Jupiter-size and 55 are larger than Jupiter. The findings, based on observations conducted May 2009 to September 2010, show a dramatic increase in the numbers of smaller-size planet candidates.

The COMPLETE three piece movement of Exoplanet by The Contortionist
Absolutely amazing musicians in this band.
At first when I heard these guys I though they weren't anything special. They might be that way for you too. I encourage you to listen to this multiple times (not all at once perhaps) and see if you can really dig into the music. It is incredible.
I DO NOT OWN ANY OF THE MUSIC
We are among the stars
Who are the operators of this boundless array?
The expedition takes us to our new home...
Speculation based on calculated reason leads me to believe we are not alone
Seeded by a greater race, we only hope to find the answers now embedded into the fabric of our minds
Are we moving forward?
Guided by the maps of progress
Imperfect perfections allow existence
We long to feel our bodies outside centrifugal conditions.
An orderly solar system will outlast this guiding center system.
As we leave our galaxy, every certainty abandoned.
The referential lawns of man are lost, nothing is relative.
Cold and empty space surrounds and swells.
Time is moving at invariable speeds and our instruments are useless.
Oscillating obsession, beautiful apparatus.
These cycles put my mind at ease.
Bodies cannot sustain what this was built for.
The body cannot sustain what this was built for.
We worship oscillation, no other way.
The microcosm is in exhibition.
Terrestial shaped into a magnificent realm.
Our colonial settlements are threatened by the sky.
The circling disk of ice watches quietly from a distance.
Refracting nebulaic dust has pierced the outer shell.
A blooming world is being ripped apart.
Planetary wide scorching from the focused light.
This extra solar vessel, orbiting the cluster.
Ejects the sample pods of the Eden passengers.
As for us, we must migrate.
This exoplanet has failed.
~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.

Hubblecast 22: Hubble Space Telescope Directly Observes Exoplanet Orbiting Fomalhaut.
The NASA/ESA Hubble Space Telescope has discovered an extrasolar planet, for the first time using direct visible-light imaging. The strange world is far-flung from its parent star, is surrounded by a colossal belt of gas and dust, and may even have rings more impressive than Saturn's.

WISE All-Sky Data Release Scheduled for March 2012: http://wise2.ipac.caltech.edu/docs/release/allsky/
The centuries-old quest for other worlds like our Earth has been rejuvenated by the intense excitement and popular interest surrounding the discovery of hundreds of planets orbiting other stars. There is now clear evidence for substantial numbers of three types of exoplanets; gas giants, hot-super-Earths in short period orbits, and ice giants. The following websites are tracking the day-by-day increase in new discoveries and are providing information on the characteristics of the planets as well as those of the stars they orbit: Extrasolar Planets Encyclopedia, New Worlds Atlas, and Current Planet Count Widget. The challenge now is to find terrestrial planets (i.e., those one half to twice the size of the Earth), especially those in the habitable zone of their stars where liquid water and possibly life might exist. The Kepler Mission, NASA Discovery mission #10, is specifically designed to survey our region of the Milky Way galaxy to discover hundreds of Earth-size and smaller planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets. Results from this mission will allow us to place our solar system within the continuum of planetary systems in the Galaxy.
