New Vista of Milky Way Center Unveiled
Permeating the region is a diffuse haze of X-ray light from gas that has been heated to millions of degrees by winds from massive young stars – which appear to form more frequently here than elsewhere...

In the first observation if its kind, scientists at the Weizmann Institute of Science and San Diego State University were able to watch what happens when a star the size of 50 suns explodes. As they c...
Physics and Astronomy | Read moreAn upper mass limit for black holes
Once considered rare and exotic objects, black holes are now known to exist throughout the Universe, with the largest and most massive found at the centres of the largest galaxies. These "ultra-m...
Physics and Astronomy | Read moreStudy sheds new light on early star formation in the universe
Cosmologists from Durham University, publishing their results in the prestigious international academic journal, Science, suggest that the formation of the first stars depends crucially on the nature ...
Studies and Analyses | Read moreControlled by Distant Explosions
A time-series of high-resolution spectra in the optical and ultraviolet has twice been obtained just a few minutes after the detection of a gamma-ray bust explosion in a distant galaxy. The internatio...

Astrophysical Virtual Observatory Proves To Be Essential Tool Active galaxies Active galaxies are breathtaking objects. Their compact nuclei (AGN = Active Galaxy Nuclei) are ...
Physics and Astronomy | Read moreMagnetic ’slinky effect’ may power aurora
The spectacular aurora borealis displays that light up the northern nights could be powered by a gigantic "slinky" effect in Earth’s magnetic field lines, according to research performed a...
Earth Sciences | Read moreGiant Black Holes and Disks on the Balance
Quasars and active galactic nuclei (AGN) are likely powered by matter accretion onto a super-massive black hole located at their center. Before being swallowed by the black hole, matter spirals...
Physics and Astronomy | Read moreBlack hole dynamo may be cosmos’ ultimate electricity generator
Researchers at the U.S. Department of Energy’s Los Alamos National Laboratory believe that magnetic field lines extending a few million light years from galaxies into space may be the resu...
Physics and Astronomy | Read moreX-Rays Examine Colliding Galaxies
Galaxies were once thought of as `island universes` evolving slowly in complete isolation. This is now known not to be the case. By using the world`s most powerful X-ray observatories, UK astro...
