NASA finds a large amount of water in an exoplanet's atmosphere

Much like detectives study fingerprints to identify the culprit, scientists used NASA's Hubble and Spitzer space telescopes to find the 'fingerprints' of water in the atmosphere of a hot, bloated, Saturn-mass exoplanet some 700 light-years away.

Pulsar watchers close In on galaxy merger history

For the past twelve years, a group of astronomers have been watching the sky carefully, timing pulses of radio waves being emitted by rapidly spinning stars called pulsars, first discovered 50 years ago.

Improved Hubble yardstick gives fresh evidence for new physics in the universe

Astronomers have made the most precise measurements of the expansion rate of the universe since it was first calculated nearly a century ago. Intriguingly, the results are forcing astronomers to consider that they may be seeing evidence of something unexpected at work in the universe.

Astronomers reveal secrets of most distant supernova ever detected

An international team of astronomers has confirmed the discovery of the most distant supernova ever detected - a huge cosmic explosion that took place 10.5 billion years ago, or three-quarters the age of the Universe itself.

Supermassive black hole model predicts characteristic light signals at cusp of collision

A new simulation of supermassive black holes uses a realistic scenario to predict the light signals emitted in the surrounding gas before the masses collide.

New models give insight into the heart of the Rosette Nebula

A hole at the heart of a stunning rose-like interstellar cloud has puzzled astronomers for decades. But new research offers an explanation for the discrepancy between the size and age of the Rosetta Nebula's central cavity and that of its central stars.

Supermassive black holes can feast on one star per year

Researchers have discovered a mechanism that explains the persistence of asymmetrical stellar clusters surrounding supermassive black holes in some galaxies and suggests that during post-galactic merger periods, orbiting stars could be flung into the black hole and destroyed at a rate of one per year.
