The Higgs boson

So it has finally been announced (4th July 2012) that the Higgs boson has been discovered but what is it? Almost 50 years ago Peter Higgs proposed the existence of the Higgs boson and since then scientists have been looking for it! At the cost of billions of pounds, it has finally been found. Was it worth all the effort? In this Horizon episode first broadcast on 9th January 2012, Physicists working at CERN explain what the Higgs boson is? Is it really the biggest scientific discovery for a hundred years? Prof Jim Al-Khalli presents this Horizon Special produced by the BBC. Should Professor Peter Higgs get knighted and receive the Nobel Prize? Is the nickname "The God Particle" misleading?

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 .

NASA SDO - Aurora; What Causes Them?

Aurora are colorful lights in the night time sky primarily appearing in Earth's polar regions. But what causes them? The culprit behind aurora is our own Sun and the solar plasma that is ejected during a magnetic event like a flare or a coronal mass ejection. This plasma travels outward along with the solar wind and when it encounters Earth's magnetic field, it travels down the field lines that connect at the poles. Atoms in the plasma interacts with atoms in Earth's upper atmosphere.

NASA SDO - Growing Sunspot

The video from the Helioseismic and Magnetic Imager onboard SDO shows the Active Region 1393 from January 6 through January 8 and demonstrates how sunspots can quickly change shape and size. Sunspots are planet-sized magnets created by the Sun's inner magnetic dynamo. Like all magnets in the Universe, sunspots have north (N) and south (S) magnetic poles Sunspots, temporary disturbances in the Sun's photosphere, are the most visible advertisement of the solar magnetic field. They appear dark because temperatures are considerably lower than in surrounding areas. Sunspots occur where the magnetic field lines emerge from the inside of the Sun to form expanding loops above its surface. Sunspots usually show up as small forms that are irregularly shaped, and grow within days or weeks to their full size. While they can last weeks or months, they do eventually disappear, often by breaking into smaller and smaller sunspots. Credit: NASA SDO

NASA SDO - X1.1 Solar Flare, March 5, 2012

After several days of a quiet Sun, the solar activity is now high again. Big sunspot AR1429, which emerged on March 2nd, is crackling with strong flares. This morning brought the strongest so far--an X1-class eruption on March 5th at 0413 UT. This flare propelled a bright Coronal Mass Ejection into Space, which will probably miss Earth, but hit Mercury and Venus. Even if this CME misses, high-latitude sky watchers should still be alert for auroras in the nights ahead. An M2-class eruption from the same sunspot on March 4th produced another, wider CME that might yet intersect Earth. The cloud is expected to deliver a glancing blow to our planet's magnetic field on March 6th at 04:30 UT (+/- 7 hr). Take a look at the forecast from our friends at the NASA Goddard Space Weather Lab: http://iswa.gsfc.nasa.gov/downloads/20120305_085600_anim.tim-den.gif Credit: NASA SDO

NASA SDO - Today's Un-Boring Sun; December 7, 2011

December 7, 2011; Today's Sun in various wavelengths showing various temperatures and layers of the Sun. Not only that, but we also added the Sun's magnetic field lines to the view. These images were taken at approx. the same time We start off looking at the 6,000 degrees C. Photosphere. See the various sunspots on the "surface" of the Sun? Now let's transition into the region between the Chromosphere and the Corona, at about 1 million degrees C. From there we go into a composite of three different wavelengths showing temperatures up to 2 million degrees C. And at the end we add the complex field of Magnetic Field lines to the various active regions. And who says the Sun is boring? Credit: NASA SDO Thanks to Steele Hill

NASA SDO - Filament Snap, November 14, 2011

And within just a few hours the very massive filament (see post from earlier today) is approx. 1/3 shorter. This movie shows the developments from 13:00 to 16:00 UT on November 14, 2011. A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona. A prominence forms over timescales of about a day, and stable prominences may persist in the corona for several months, looping hundreds of thousands of miles into space. Scientists are still researching how and why prominences are formed. The red-glowing looped material is plasma, a hot gas comprised of electrically charged hydrogen and helium. The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun's internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma. Credit: NASA SDO

NASA - Aurorae from Space

Lately, the International Space Station has been flying through geomagnetic storms, giving astronauts an close-up view of the aurora borealis just outside their windows. These videos were taken by the crew of Expedition 30 on board the International Space Station. First, get an introduction into the beauty of aurorae. 1st Segment: The sequence of shots was taken March 3, 2012 from 17:59:48 to 18:16:25 GMT, on a pass from eastern Kenya, near the Indian Ocean, to the South Indian Ocean, east of the Kerguelen Islands. This video begins as the ISS travels southeast from eastern Africa over the Arabian Sea and the Indian Ocean. The first land we see is that of the Mauritius and Reunion Islands east of Madagascar. The pass continues over the Indian Ocean, where there are heavy clouds blocking the view of the water. Finally, the Aurora Australis begins to appear, as well as a faded view of the Milky Way. 2nd Segment: The sequence of shots was taken March 4, 2012 from 17:19:17 to 17:27:10 GMT, on a pass over the South Indian Ocean. This video again focuses on the Aurora Australis as the ISS passes over the South Indian Ocean, from northeast of the Kerugelen Islands to south of Australia. The streaks of the aurora are very visible and active in this video, as the ISS passes right over the green lights. 3rd Segment: The sequence of shots was taken March 10, 2012 from 14:49:58 to 15:05:37 GMT, on a pass from the South Indian Ocean to southeast New Zealand. This video mainly focuses on the Aurora Australis over the Southern Hemisphere. As the ISS traveled southeast and then northeast, the crew captured the bands of the Aurora Australis as the Milky Way made an appearance in the star field. Credit: NASA ISS/JSC/Science@NASA

NASA/ESA SOHO & NASA SDO Comet Meets Sun, October 1, 2011

A comet discovered on Friday September 30, 2011 by an amateur astronomer disintegrated on Saturday October 1, 2011 when it plunged into the Sun. The Corongraph of NASA/ESA's SOHO captured the last few hours of the comet. Very shortly after the comet dove into the Sun a Coronal Mass Ejection (CME) exploded. As of current solar scientists do not believe that a comet can trigger a Coronal Mass Ejection - however, the question of if a comet could cause a magnetic instability on the Sun remains and is being studied. On July 6, 2011 the Solar Dynamics Observatory (SDO) observed a sungrazing comet and it appeared to interact with the plasma and magnetic field as it fell apart. The first two segments in this video are from October 1, 2011 and were observed by NASA/ESA's SOHO spacecraft. The last two segments were captured by NASA's SDO on July 5, 2011.

NASA SDO - Plasma Indirection

As if it could not make up its mind . . . darker, cooler plasma slid and shifted back and forth above the Sun's surface seen here for 30 hours (Feb. 7-8, 2012) in extreme ultraviolet light. An active region rotating into view provides a bright backdrop to the gyrating streams of plasma. The particles are being pulled this way and that by competing magnetic forces. They are tracking along strands of magnetic field lines. This kind of detailed solar observation with high-resolution frames and a four-minute cadence was not possible until SDO, which launched two years ago on Feb. 11, 2010. So it's our 2nd Anniversary!

NASA SDO - Lovely Loops

The Lovely Loops A close-up view of the Sun's edge shows vast loop structures made of superheated plasma, just one of which is the size of several Earths. These loops can have a wide range of temperatures, many reaching several million degrees Kelvin. The upper one of a pair of new, solar active regions that just rotated into view offered a beautiful profile view of those cascading loops spiraling above it (Jan. 15-16, 2012) following a solar flare eruption. With its ability to capture the Sun in amazing detail, SDO observed it all in extreme ultraviolet light. This particular video clip used an image every minutes to present the motion.
