Over a decade after it exploded, one of the nearest supernovae in the last 25 years has been identified. This result was made possible by combining data from the vast online archives from many of the…

Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the gravitational…

Two terrestrial planets in orbit around a sun-like star, BD +20 307, recently suffered a violent collision, astronomers at University of California Los Angeles, Tennessee State University, and…

Observations from NASA’s Cassini spacecraft have been used to build, for the first time, a 3-D picture of the sources of intense radio emissions in Saturn’s magnetic field, known as the Saturn…

A gamma-ray burst is, in a sense, a look back in time. Scientists have now seen one that happened farther back in time than any other seen before. Even before the existence of the Milky Way. Gamma-…

A study has given new insights into why Oval BA, a giant anticyclone on Jupiter also known as Red Spot Junior, suddenly turned from white to red in a period of just a few months. The Oval BA is an…

Precise measurements by the ESO instrument HARPS now show that the rotation of the Milky Way is simpler than previously thought - the much debated, apparent 'fall' of neighborhood Cepheid stars…

A group of scientists from Durham University say they have found the "missing link" between small and super-massive black holes. The researchers have discovered that a strong X-ray pulse is emitting…

An international team of scientists predict that our galaxy, the Milky Way, contains a disk of ‘dark matter’, in a paper published in Monthly Notices of the Royal Astronomical Society. Astronomers Dr…

A long-standing scientific belief holds that stars tend to hang out in the same general part of a galaxy where they originally formed. Some astrophysicists have recently questioned whether that is…
