ESA -- Astronomers using ESA's XMM-Newton observatory have found very hot gaseous haloes around a multitude of spiral galaxies similar to our Milky Way galaxy. These 'ghost-like' veils have been suspected for decades but remained elusive until now. Galaxy 'haloes' are often seen in so-called 'starburst' galaxies, the locations of concentrated star formation, but the discovery of high-temperature haloes around non-starburst spiral galaxies opens the door to new types of measurements once...

NASA -- Scientists using NASA's Chandra X-ray Observatory have discovered evidence of energetic plumes - particles that extend 300,000 light years into a massive cluster of galaxies. The plumes are due to explosive venting from the vicinity of a supermassive black hole, and they provide dramatic new evidence of the influence a black hole can have over intergalactic distances. "In relative terms, it is as if a heat source the size of a fingernail affects the behavior of a region the size of...

ESO -- The southern Reticulum constellation [1] certainly isn't a big hit for amateur astronomers. This tiny, bleak and diamond-shaped constellation, not far on the sky from the Large Magellanic Cloud, is often overlooked. But recently, astronomers had a closer look at a galaxy situated inside it. And more precisely at an exploding star hosted by the spiral galaxy NGC 1559 [2]. On the night of August 4, 2005, Australian amateur astronomer Reverend Robert Evans discovered a supernova just...

Chandra -- Distant galaxies undergoing intense bursts of star formation have been shown by NASA's Chandra X-ray Observatory to be fertile growing grounds for the largest black holes in the Universe. Collisions between galaxies in the early Universe may be the ultimate cause for both the accelerated star formation and black hole growth. By combining the deepest X-ray image ever obtained with submillimeter and optical observations, an international team of scientists has found evidence that...

The Centaurus A/M83, divided into subgroup Cen A and M83, is a complex group of galaxies located within Hydra, Centaurus, and Virgo constellations. The Cen A Subgroup, at a distance of 11.9 Mly (3.66 Mpc), is centered around Centaurus A, a nearby radio galaxy. The M83 Subgroup, at a distance of 14.9 Mly (4.56 Mpc), is centered around the Messier 83 (M83), a face-on spiral galaxy. Due to the physical closeness of both subgroups they are sometimes identified as two groups sometimes as one....

Within the Hydra, Centaurus, and Virgo constellations a complex group of galaxies resides called Centaurus A/M83. There are two subgroups within Centaurus A/M83. The first is Cen A, at a distance of 11.9 Million Light Years, is centered around Centaurus A, a close by radio galaxy. The other subgroup, M83, is at a distance of 14.9 Million Light Years and is centered around the Messier 83. Since there are two subgroups Centaurus is sometimes identified as one group and sometimes two, it will be...
