Seen in X-rays, the entire sky is aglow. Even far away from bright sources, X-rays originating from beyond our galaxy provide a steady glow in every direction. Astronomers have long…
Astronomers have turned up the first direct proof that 'standard candles' used to illuminate the size of the universe, termed Cepheids, shrink in mass, making them not quite as standard…
The first scientific results from Europe's Planck spacecraft featuring the coldest objects in the Universe have today been released…
Astronomers have found the first evidence of a magnetic field in a jet of material ejected from a young star, a discovery that points toward future breakthroughs in understanding the…
Astronomers find cosmic dust annoying when it blocks their view of the heavens, but without it the universe would be devoid of stars. Cosmic dust is the indispensable ingredient for…
Over the last 15 years, astronomers have detected nearly 500 planets orbiting stars in our cosmic neighbourhood, but none outside our Milky Way has been confirmed. Now, however, a planet…
UC Irvine astronomers, along with scientists across the globe, are discovering hundreds of new galaxies through brighter galaxies in front of them that deflect their faint light back…
An international team of scientists led by Rutgers University astrophysicists have discovered 10 new massive galaxy clusters from a large, uniform survey of the southern sky. The survey…
Surveying the microwave sky, the Planck satellite of the European Space Agency (ESA) has obtained qualitatively new images of galaxy clusters - even revealing one of them to be a previously…
Physicists from UCLA and Japan have discovered evidence of 'natural nuclear accelerators' at work in our Milky Way galaxy, based on an analysis of data from the world's largest cosmic…
