Astronomers have identified the glowing wreck of a star that exploded a mere 2,500 years ago — the blink of an eye in astronomical terms - and revealed an astrophysical novelty of the Milky Way…

A model has shown that the subsurface ocean on Jupiter's moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life. Astronomers…

Separate teams of scientists have found faint signatures of water in the atmospheres of five distant planets, the first study to conclusively measure and compare the profiles and intensities of…

In boxing a devastating puncher has heavy hands. On a cosmic scale, the high-speed 'jets' spat out by black holes pack a lot of power because they contain heavy atoms, astronomers have found. Black-…

Our Galaxy may have been swallowing "pills" — clouds of gas with a magnetic wrapper — to keep making stars for the past eight billion years, according to CSIRO astronomer Dr. Alex Hill and colleagues…

A few months ago astronomers created a new 3-D map of stars at the center of our Galaxy which cleared showed the bulge at its core. Previous explanations suggested that the stars that form the bulge…

When a star goes supernova, it shines brightly for a few weeks or months before fading away. Yet the material blasted outward from the explosion glows hundreds or thousands of years later, leaving a…

Recently, a gamma-ray burst occurred with an optical flash that peaked at magnitude 7 on the astronomical brightness scale, easily visible through binoculars. It is the second-brightest flash…

Astronomers from around the world have used data from satellites and observatories to explain the brightest Gamma-ray Burst (GRB) ever recorded. An unusually bright GRB, now deemed GRB 130427A, was…

Neutrinos can pass right through your body, the walls of your house, entire planets, even emerging from near the surface of fascinating and frightening black holes.  And now, an international…
