Astronomers using data from NASA’s Chandra X-ray Observatory, the Gemini Observatory and ESA’s XMM-Newton Observatory have made the best determination of the power of a supernova explosion long after…

As Georg von Hippel wrote about here, a powerful stellar explosion detected March 19 by NASA's Swift satellite has shattered the record for the most distant object that could be seen with the naked…

Located at the University of Utah, the High Resolution Fly's Eye (HiRes) is an experiment to study the highest energy cosmic rays to determine the energy, direction, and chemical composition of the…

Life on another planet? No, it's far too hot on HD 189733b for that, but the Hubble Space Telescope's first ever detection of an organic molecule in the atmosphere of a planet orbiting another star…

Amino acids are organic molecules that are the backbone of the proteins that build many of the structures and drive many of the chemical reactions inside living cells. The production of proteins is…

In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same…

If participants in the Dark Ages Lunar Interferometer study have their way, a telescope on the moon will allow astronomers to see 'back in time' and study the young Universe during the first 100…

Astronomers at the University of Rochester have announced that low-mass stars and possibly even super-Jupiter-sized planets may be responsible for creating some of the most breathtaking objects in…

Astronomers using ESO's New Technology Telescope have measured the distribution of mass inside a dark filament in a molecular cloud with an amazing level of detail and to great depth, based on a new…

Astrophysicists are having a heated debate over the wave structure of the Sun’s Corona - a debate which may one day influence solar weather forecasting and the theory behind fusion reactors. The Sun…
