GLAST will open a new window on this high-energy world. With GLAST, astronomers will have a superior tool to study how black holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds. Physicists will be able to search for signals of new fundamental processes that are inaccessible in ground-based accelerators and observatories. GLAST's spectacular high-energy gamma-ray "eyeglasses" will reveal hidden wonders, opening our minds to new possibilities and discoveries, expanding our understanding of the Universe and our place in it.

 | 5of5_Cosmic Odyssey-Extreme Astronomy This is part 5 of a 5 part episode. To watch the full show go to my channel (Zuke696) then go to my Playlist, find the show then click Play All - Extreme Astronomy - At the edge of the spectral frontier, strange things go bang! in the night. High-energy radiation, the alarm signal of atoms in extreme distress, can only be detected in space through the advanced technology of X-ray telescopes and gamma-ray satellites. In Extreme Astronomy, rare but spectacular catastrophes caused by high-energy radiation -- such as supernovas, stars in collision, and planets falling into black holes -- are glimpsed through these instruments, teaching us more about our universe. |
 | (2of5) Mega Disasters - Gamma Ray Burst This is part 2 of a 5 part episode. To watch the full show go to my channel (Zuke696) then go to my Playlist, find the show then click Play All - Scientists believe gamma ray bursts were responsible for a mass extinction 450 million years ago. The gamma rays strip away the ozone layer and generate chemical smog, producing a widespread chill that grips the Earth. An expected electromagnetic pulse will zap all of our electronics. How will our modern cities hold up in the face of a previous global catastrophe? |

 | HUBBLE TELESCOPE - Astronomy The Hubble Space Telescope (HST) is a telescope in orbit around the Earth, named after astronomer Edwin Hubble. Its position outside the Earth's atmosphere provides significant advantages over ground-based telescopes — images are not blurred by the atmosphere, there is no background from light scattered by the air, and the Hubble can observe ultra-violet light that is normally absorbed by the ozone layer in observations made from Earth. Since its launch in 1990, it has become one of the most important instruments in the history of astronomy. With it, astronomers have made many observations leading to breakthroughs in astrophysics. Hubble's Ultra Deep Field is the most sensitive astronomical optical image ever taken. From its original conception in 1946 until its launch, the project to build a space telescope was beset by delays and budget problems. Immediately after its 1990 launch, it was found that the main mirror suffered from spherical aberration, severely compromising the telescope's capabilities. However, after a servicing mission in 1993, the telescope was restored to its intended quality and became a vital research tool as well as a public relations boon for astronomy. The HST is part of NASA's Great Observatories series, with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.[1] Hubble is a collaboration between NASA and the European Space Agency. |
 | Greatest Discoveries with Bill Nye: Astronomy 1/5 Bill Nye and the Discovery Channel give you the greatest discoveries in science. In this episode, Nye covers Einstein's theory of general relativity, demonstrates how Hubble determined that the universe is expanding, and discusses the 20th-century advancements that help us understand gamma ray bursts, black holes, pulsars, and quasars. Highlights include Edmond Halley, whose discovery of comets orbiting the sun proved that gravity works in space, and Alexander and Caroline Herschel, whose map of the sky brought new understanding of the universe. |

 | Seeing the Universe Through Gamma-Ray Eyes GLAST, the Gamma-ray Large Area Telescope, was launched into Earth orbit on June 11, 2008. Unlike the human eye, it can see gamma rays, a powerful form of light that is above the spectrum of visible light. GLAST will open new views of such celestial objects as gamma ray bursts, black holes, spinning neutron stars and jets of highly charged particles. It may even detect signs of dark matter. GLAST is a $690-million NASA project, a consortium of six countries and 14 U.S. research institutions. At Stanford, project members came from SLAC, a U.S. Energy Department lab; the Physics Department; the Hansen Experimental Physics Laboratory; and the Kavli Institute for Particle Astrophysics and Cosmology.

 | Big Bang Astronomy Theories Swift satellite Swift is a satellite designed by Penn State researchers and launched by NASA to study gamma-ray bursts. Launched in November of 2005, the satellite was named after the swift, a small, quickly moving bird. Catching a GRB is no easy task. The burst can appear from any direction without warning and can last for only a few milliseconds to just over a minute. So, the satellite has to move quickly and be in position to capture the data. According to NASA, no other satellite turns faster. In addition to GRBs, Swift searches and records other phenomena it observes in the sky. |
