Is the Milky Way doomed to be destroyed by galactic bombardment? Unlikely

— 1 Sep 2009 13:25 | Astronomy

As scientists attempt to learn more about how galaxies evolve, an open question has been whether collisions with our dwarf galactic neighbours will one day tear apart the disk of the... — full story

— 9 May 2009 14:50 | Physics

Imagine a time when the entire Universe froze. According to a new model for dark energy, that is essentially what happened about 11.5 billion years ago, when the Universe was a quarter... — full story

Refined Hubble constant narrows possible explanations for dark energy

— 8 May 2009 05:19 | Astronomy

Whatever dark energy is, explanations for it have less wiggle room following a Hubble Space Telescope observation that has refined the measurement of the universe's present expansion... — full story

Study plunges standard theory of cosmology into crisis

— 5 May 2009 16:55 | Astronomy

As modern cosmologists rely more and more on the ominous 'dark matter' to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance... — full story

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... — full story

The optical image that confirmed that 2XMM J083026+524133 is a distant cluster of galaxies, taken by the Large Binocular Telescope in Arizona. The X-ray emission from the cluster of galaxies is shown in blue at the centre of the image. The individual galaxies in the cluster are the small dots inside the blue glow, (c) ESA XMM-Newton, EPIC, LBT, LBC, AIP (J. Kohnert)XMM-Newton discovers the most massive cluster of galaxies

— 25 Aug 2008 12:05 | Astronomy

ESA's orbiting X-ray observatory XMM-Newton has discovered the most massive cluster of galaxies seen in the distant Universe until now. The galaxy cluster is so big that there can only... — full story
