Chandra Data Helps Solve The Puzzle Of Why Galaxy Clusters Contain So Few Stars

Chuck Bednar for redOrbit.com - Your Universe Online New observations of the Perseus and Virgo galaxy clusters made using NASA’s Chandra X-ray Observatory suggest that turbulence may be the reason that hot gas there has been unable to cool,...

WASHINGTON, Oct. 27, 2014 /PRNewswire-USNewswire/ -- The same phenomenon that causes a bumpy airplane ride, turbulence, may be the solution to a long-standing mystery about stars' birth, or the absence of it, according to a new study using data from NASA's Chandra X-ray Observatory. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Galaxy clusters are the largest objects in the universe, held together by gravity. These behemoths contain hundreds or thousands of individual galaxies...

Provided by Janet Anderson, Marshall Space Flight Center and Megan Watzke Chandra X-ray Center Every year, NASA’s Chandra X-ray Observatory looks at hundreds of objects throughout space to help expand our understanding of the Universe. Ultimately, these data are stored in the Chandra Data Archive, an electronic repository that provides access to these unique X-ray findings for anyone who would like to explore them. With the passing of Chandra’s 15th anniversary in operation on August...

The Nuclear Spectroscopic Telescope Array, or NuSTAR, recently spotted the brightest pulsar ever recorded using X-ray optics designed by a team that included researchers from the Lawrence Livermore National Laboratory. Livermore, California (PRWEB) October 10, 2014 A supernova is the cataclysmic death of a star, but it seems its remnants shine on. Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar -- a dense stellar...

WASHINGTON, Oct. 8, 2014 /PRNewswire-USNewswire/ -- Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over from a supernova explosion - ever recorded. The discovery was made with NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. http://photos.prnewswire.com/prnvar/20081007/38461LOGO "You might think of this pulsar as the 'Mighty Mouse' of stellar remnants," said Fiona...

exoplanet WASP-18b

NASA A planet may be causing the star it orbits to act much older than it actually is, according to new data from NASA’s Chandra X-ray Observatory. This discovery shows how a massive planet can affect the behavior of its parent star. The star, WASP-18, and its planet, WASP-18b, are located about 330 light-years from Earth. WASP-18b has a mass about 10 times that of Jupiter and completes one orbit around its star in less than 23 hours, placing WASP-18b in the “hot Jupiter” category...

NASA's Marshall Space Flight Center The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the sun, it is also extremely volatile and is expected to have at least one supernova explosion in the future. [ Watch the Video: Eta Carinae: Our Neighboring Superstars ] As one of the first objects observed by NASA’s Chandra X-ray Observatory after its launch some 15...

NASA/Harvard-Smithsonian Center for Astrophysics New data from NASA’s Chandra X-ray Observatory offer a glimpse into the environment of a star before it exploded earlier this year, and insight into what triggered one of the closest supernovas witnessed in decades. The data gathered on the Jan. 21 explosion, a Type Ia supernova, allowed scientists to rule out one possible cause. These supernovas may be triggered when a white dwarf takes on too much mass from its companion star,...

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...

Chandra X-ray Observatory -- NASA's Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. Chandra is designed to observe X-rays from high-energy regions of the universe, such as the remnants of exploded stars. The Observatory has three major parts: (1) the X-ray telescope, whose mirrors focus X-rays from celestial objects; (2) the science instruments which record the X-rays so...
