Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Chandra, one of NASA's current "Great Observatories," along with the Hubble Space Telescope and Spitzer Space Telescope, is...

European Space Agency Selects Athena Advanced Telescope For Study Of High-Energy Astrophysics
2014-06-27 09:41:59

Gerard LeBlond for redOrbit.com - Your Universe Online The European Space Agency (ESA) is in the process of launching a second “Large-class” mission to explore the universe for high-energy astrophysics and selected the Athena advanced telescope for the task. The mission is scheduled for launch in 2028 to study the hot and energetic Universe as part of ESA’s Cosmic Vision 2015 to 2025 plan. Athena is a large X-ray telescope combined with state-of-the-art scientific instruments...

ESA’s New X-ray Optics To Observe The Hot Universe
2014-05-16 03:41:51

ESA A new idea to use super-polished silicon wafers as the heart of a telescope is set to reveal more of the hot, high-energy Universe, peering back into its turbulent history. Invisible X-rays tell us about the very hot matter in the Universe – black holes, supernovas and superheated gas clouds. Today’s X-ray observatories, ESA’s XMM-Newton and NASA’s Chandra, were launched in the last century, and are still delivering world-class science. But they are starting to age. To...

April Flowers for redOrbit.com - Your Universe Online A new superpowered small black hole, called MQ1, has been discovered by a team of Australian and American astronomers who were studying nearby galaxy M83. MQ1 is the first object of its kind to be studied in this much detail. Previously, astronomers have found a few compact objects as powerful as MQ1, but they have been unable to calculate the size of the black hole contained within until now. Using multiple telescopes, the team's...

NASA Satellite Discovers Cloudy Conditions Around Black Holes

[ Watch the Video: The Cloudy Cores of Active Galaxies ] Lee Rannals for redOrbit.com - Your Universe Online An international team of astronomers used NASA’s Rossi X-ray Timing Explorer (RXTE) satellite data and found huge clouds of gas orbiting supermassive black holes. Scientists collected 16 years of data from RXTE, a decommissioned low-earth orbit satellite that was equipped with instruments that measured variations in X-ray sources. This treasure trove of data revealed a dozen...

Chandra X-ray Observatory Sees Runaway Pulsar Firing A Record-breaking Jet
2014-02-19 09:27:55

NASA NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles. The pulsar, a type of neutron star, is known as IGR J11014-6103. IGR J11014-6103's peculiar behavior can likely be traced back to its birth in the collapse and subsequent explosion of a massive star. Originally discovered with the European Space Agency satellite...

New Look At Old Galactic Friend
2014-02-07 09:05:06

NASA Just weeks after NASA’s Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A (Cen A, for short). This galaxy, at a distance of about 12 million light years from Earth, contains a gargantuan jet blasting away from a central supermassive black hole. Since then, Chandra has returned its attention to this galaxy, each time gathering more data. And, like an old family photo that has been digitally restored, new processing techniques are providing...

Columbia launched from Kennedy Space Center on December 2, 1990 at 1:49 AM EST and landed at Edwards AFB on December 10 at 9:54 PM PST. The shuttle orbited 144 times at an altitude of 190 nautical miles at an inclination of 28.45 degrees and travelled 3.7 million miles. The mission lasted 8 days, 23 hours, 5 minutes, and 8 seconds. The primary objectives were round-the-clock observations of the celestial sphere in ultraviolet and x-ray astronomy with the ASTRO-1 observatory consisting of...

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

X-ray Pulsar -- This dramatic artist's vision shows a city-sized neutron star centered in a disk of hot plasma drawn from its enfeebled red companion star. Ravenously accreting material from the disk, the neutron star spins faster and faster emitting powerful particle beams and pulses of X-rays as it rotates 400 times a second. Could such a bizarre and inhospitable star system really exist in our Universe? Based on data from the orbiting Rossi X-Ray Timing Explorer (RXTE) satellite,...

Gamma-Ray Burst -- In astronomy, Gamma-ray bursters (GRBs) are flashes of gamma rays that last from seconds to hours, the longer ones being followed by several days of X-ray afterglow. They occur at random positions in the sky several times each day. They are now believed to result from tremendous explosions in far away galaxies, during the creation of a black hole from a dying star or two colliding neutron stars. The black hole, surrounded by a rotating disk of matter falling into it,...
