X-ray Signal Detected During Black Hole's Destruction Of Passing Star
2012-08-03 15:48:00

[Watch Video] Lee Rannals for redOrbit.com — Your Universe Online Astronomers have identified an X-ray signal that followed an observation made last year of a quiescent black hole in a distant galaxy. The black hole discovered by the team last year was seen erupting after shredding and consuming a passing star. Astronomers then witnessed days following the observation a distinctive X-ray signal that comes from matter on the verge of falling into the black hole. This...

Scotch Tape Inspires X-ray Telescope Design
2012-07-27 11:57:46

Lee Rannals for redOrbit.com - Your Universe Online While some find it as the source of inspiration for wrapping gifts, Scotch tape inspired one scientist at NASA to build a special X-ray mirror. NASA scientist Maxim Markevitch and a team of X-ray optics experts at the space agency's Goddard Space Flight Center are looking into the feasibility of creating a low-cost mirror out of plastic tape. "I remember looking at a roll of Scotch tape and thinking, 'was it possible to use the same...

WASHINGTON, July 20, 2012 /PRNewswire-USNewswire/ -- A telescope launched July 11 aboard a NASA sounding rocket has captured the highest-resolution images ever taken of the sun's million-degree atmosphere called the corona. The clarity of the images can help scientists better understand the behavior of the solar atmosphere and its impacts on Earth's space environment.

Belching Black Hole
2012-07-09 11:03:28

Observations with CSIRO's Australia Telescope Compact Array have confirmed that astronomers have found the first known "middleweight" black hole. Outbursts of super-hot gas observed with a CSIRO radio telescope have clinched the identity of the first known "middleweight" black hole, Science Express reports online today. Called HLX-1 ("hyper-luminous X-ray source 1"), the black hole lies in a galaxy called ESO 243-49, about 300 million light-years away. Before it was found,...

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have spotted the first known "middleweight" black hole, according to a publication in Science Express. The black hole was found with a CSIRO radio telescope in a galaxy called ESO 243-49, which is about 300 million light-years away. Before the black hole was found, astronomers had only known of supermassive black holes and "stellar mass" ones. "This is the first object that we're really sure is an intermediate-mass...

XMM-Newton Captures The Beating Heart Of A Newborn Star

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online ESA's XMM-Newton has helped to reveal the violent behavior of a young Sun-like star spinning at high speed and spewing out super-hot plasma. Along with information from NASA´s Chandra and Japan´s Suzaku, the findings shed new light on one of the most primary issues in astronomy: the birth of stars like our own Sun. Such stars are born from clouds of gas and dust. These fall apart under gravity...

Astronomers Spot Fastest Moving Pulsar Ever
2012-06-29 13:31:30

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online Researchers may have discovered the fastest moving pulsar ever seen using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. Astronomers used X-ray observations, combined with infrared data from the 2MASS project and optical data from the Digitized Sky Survey to find evidence for the record-breaking pulsar. The XMM-Newton image was produced when a massive star exploded as a supernova, leaving behind a...

WASHINGTON, June 28, 2012 /PRNewswire-USNewswire/ -- An international team of astronomers using data from NASA's Hubble Space Telescope has made an unparalleled observation, detecting significant changes in the atmosphere of a planet located beyond our solar system. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The scientists conclude the atmospheric variations occurred in response to a powerful eruption on the planet's host star, an event observed by NASA's Swift...

NuSTAR To Help Scientists Solve Supernova Explosion Mystery
2012-06-18 04:01:37

[ Watch the Video ] Somewhere in the Milky Way, a massive old star is about to die a spectacular death. As its nuclear fuel runs out, the star begins to collapse under its own tremendous weight. Crushing pressure triggers new nuclear reactions, setting the stage for a terrifying blast. And then... nothing happens. At least that's what supercomputers have been telling astrophysicists for decades. Many of the best computer models of supernovas fail to produce an explosion. At the end of...

Lee Rannals for redOrbit.com Commercialized space industry has taken another step in collaboration with NASA as the space agency's NuSTAR telescope launched Wednesday morning. NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) was launched in a unique way by The Orbital Science Corporation's "Stargazer" plane. Stargazer took off from Kwajalein Atoll, and released its Pegasus rocket, which carried NASA's NuSTAR the rest of the way towards space. "Pegasus is our most unique...

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,...
