High-resolution imaging reveals black hole’s hideout in extra-galactic star cluster. Like detectives carefully building a case, astronomers gathered evidence and eliminated suspects until they found…
New data from the NASA/ESA Hubble Space Telescope has provided the strongest evidence yet for mid-sized black holes in the Universe. Hubble confirms that this…
Eighty-five percent of the universe is composed of dark matter, but we don’t know what, exactly, it is. A new study from the University of…
Astronomers using ESA’s XMM-Newton and NASA’s Chandra X-ray space observatories, along with radio telescopes on ground, have spotted the aftermath of the most powerful explosion…
Material falling into a black hole casts X-rays out into space – and now astronomers have used the echoes of this radiation to map the…
Material falling into a black hole casts X-rays out into space – and now, for the first time, ESA’s XMM-Newton X-ray observatory has used the…
Orange Dwarf Stars Most Likely to Host Planets To date astronomers have discovered over 4,000 planets orbiting other stars. Statistically, there should be over 100…
Two decades ago, on December 10, 1999, an Ariane 5 rocket climbed into the morning sky from Kourou, French Guiana. It carried into orbit the…
Fancy a cup of cosmic tea? This one isn’t as calming as the ones on Earth. In a galaxy hosting a structure nicknamed the “Teacup,”…
A UK team of astronomers report the first detection of matter falling into a black hole at 30% of the speed of light, located in…
An enigmatic X-ray source revealed as part of a data-mining project for high-school students shows unexplored avenues hidden in the vast archive of ESA’s XMM-Newton…
Astronomers using ESA’s XMM-Newton space observatory have probed the gas-filled haloes around galaxies in a quest to find ‘missing’ matter thought to reside there, but…
A team of U.S. astronomers studying the star RZ Piscium has found evidence suggesting its strange, unpredictable dimming episodes may be caused by vast orbiting…
An innovative interpretation of X-ray data from a cluster of galaxies could help scientists fulfill a quest they have been on for decades: determining the…
Using ESA’s XMM-Newton and NASA’s Chandra X-ray observatories, astronomers reveal that Jupiter’s intense northern and southern lights pulse independently of each other. The study, published…
New research indicates older Sun-like stars settle down relatively quickly, boosting prospects for life to develop on planets around them. A new X-ray study has…
A team of scientists has measured rapidly varying temperatures in hot gas emanating from around a black hole for the first time. These ultrafast “winds”…
