These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets. A team of astronomers used NASA's Chandra X-ray Observatory, in combination with ultraviolet, optical, and infrared data, to show where some of the most treacherous places in a star cluster may be, where planets' chances to form are diminished.

This introduction to the world of Chandra's high-resolution X-ray imaging capabilities included an unprecedented view of Cassiopeia A, the remains of an exploded star located about 11,000 light-years from Earth. Over the years, Chandra's views of Cassiopeia A have become some of the telescope's best-known images. To mark the anniversary of this milestone, new sonifications of three images -- including Cassiopeia A (Cas A) -- are being released. Sonification is a process that translates astronomical data into sound, similar to how digital data are more routinely turned into images. This translation process preserves the science of the data from its original digital state but provides an alternative pathway to experiencing the data.

These features, which span at least half a million light years, provide insight into how the Coma cluster has grown through mergers of smaller groups and clusters of galaxies to become one of the largest structures in the Universe held together by gravity.

This discovery holds important implications for understanding black holes.

The hot gas cloud is likely caused by a collision between a dwarf galaxy and a much larger galaxy called NGC 1232.

A major campaign using NASA's Chandra X-ray Observatory and several other satellites shows magnetars may be more diverse - and common - than previously thought. Chandra X-ray Observatory /articles/black-hole-powered-jets-plow-into-galaxy/?sc=rsin /articles/black-hole-powered-jets-plow-into-galaxy/?sc=rsin Wed, 15 May 2013 14:00:00 EST The intense gravity of a supermassive black hole can be tapped to produce immense power in the form of jets moving at millions of miles per hour. A composite image shows this happening in the galaxy known as 4C+29.30 where X-rays from Chandra (blue) have been combined with optical (gold) and radio (pink) data. The X-rays trace the location of superheated gas around the black hole, which is estimated to weight 100 million times the mass of our Sun.

This unusually large reservoir of gas contains as much mass as 10 billion Suns, spans about 300,000 light years, and radiates at a temperature of more than 7 million degrees.

Many navigators used this object to make their way across the oceans. A new composite image from three NASA telescopes -- Chandra, Hubble, and Spitzer -- shows this galaxy like Ferdinand Magellan, who lends his name to the SMC, could never have imagined.

This supernova, discovered in 1604 by Johannes Kepler, belongs to an important class of objects that are used to measure the rate of expansion of the Universe. Chandra X-ray Observatory /articles/probing-extreme-matter-through-observations-of-neutron-stars/?sc=rsin /articles/probing-extreme-matter-through-observations-of-neutron-stars/?sc=rsin Wed, 06 Mar 2013 12:00:00 EST Neutron stars, the ultra-dense cores left behind after massive stars collapse, contain the densest matter known in the Universe outside of a black hole. New results from Chandra and other X-ray telescopes have provided one of the most reliable determinations yet of the relation between the radius of a neutron star and its mass. These results constrain how nuclear matter - protons and neutrons, and their constituent quarks - interact under the extreme conditions found in neutron stars.

The remnant appears to be the product of a rare explosion in which matter is ejected at high speeds along the poles of a rotating star.

Chandra X-ray Observatory /articles/searching-for-the-best-black-hole-recipe/?sc=rsin /articles/searching-for-the-best-black-hole-recipe/?sc=rsin Thu, 06 Dec 2012 10:00:00 EST In this holiday season of home cooking and carefully-honed recipes, some astronomers are asking: what is the best mix of ingredients for stars to make the largest number of plump black holes? They are tackling this problem by studying the number of black holes in galaxies with different compositions. One of these galaxies is the ring galaxy NGC 922 that was formed by the collision between two galaxies. Chandra X-ray Observatory /articles/record-setting-x-ray-jet-discovered/?sc=rsin /articles/record-setting-x-ray-jet-discovered/?sc=rsin Wed, 28 Nov 2012 11:00:00 EST A jet of X-rays from a supermassive black hole 12.4 billion light years from Earth has been detected by NASA's Chandra X-ray Observatory. This is the most distant X-ray jet ever observed and gives astronomers a glimpse into the explosive activity associated with the growth of supermassive black holes in the early universe.

A30), show one of the clearest views ever obtained of a special phase of evolution for these objects. Chandra X-ray Observatory /articles/revealing-a-mini-supermassive-black-hole/?sc=rsin /articles/revealing-a-mini-supermassive-black-hole/?sc=rsin Wed, 24 Oct 2012 14:45:00 EST One of the lowest mass supermassive black holes ever observed in the middle of a galaxy has been identified, thanks to NASA's Chandra X-ray Observatory and other observatories. The host galaxy is of a type not expected to harbor supermassive black holes, suggesting that this black hole, while related to its supermassive cousins, may have a different origin. Chandra X-ray Observatory /articles/a-planetary-nebula-gallery/?sc=rsin /articles/a-planetary-nebula-gallery/?sc=rsin Wed, 10 Oct 2012 14:30:00 EST This gallery shows four planetary nebulas from a survey of such objects in the solar neighborhood made with NASA's Chandra X-ray Observatory. X-ray emission from Chandra is colored purple and optical emission from the Hubble Space Telescope is colored red, green and blue. A planetary nebula is a phase of stellar evolution that the sun should experience several billion years from now, when becomes a red giant and then sheds most of its outer layers.
