Rare Galaxy Merger Gives New Insights of Galaxy Evolution

  A rare encounter between two gas-rich galaxies spotted by ESA’s Herschel space observatory indicates a solution to an outstanding problem: how did massive, passive galaxies form in the early Universe? Several telescopes have teamed up to discover a rare and massive merging of two galaxies that took place when the Universe was just 3 [continue reading]

ALMA Pinpoints Early Galaxies at Record Speed

  A team of astronomers has used the new ALMA (Atacama Large Millimeter/submillimeter Array) telescope to pinpoint the locations of over 100 of the most fertile star-forming galaxies in the early Universe. ALMA is so powerful that, in just a few hours, it captured as many observations of these galaxies as have been made by [continue reading]

Cosmic Crisis: Star Formation Decreases Drastically

  In the largest ever study of its kind, an international team of Portuguese, UK, Japanese, Italian and Dutch astronomers has established that the rate of formation of new stars in the Universe is now only 1/30th of its peak and that this decline is only set to continue. The team, led by David Sobral of [continue reading]

A Surprising Trend in Galaxy Evolution Uncovered (with Videos)

  A comprehensive study of hundreds of galaxies observed by the Keck telescopes in Hawaii and NASA’s Hubble Space Telescope has revealed an unexpected pattern of change that extends back 8 billion years, or more than half the age of the Universe. This plot shows the fractions of settled disk galaxies in four time spans, [continue reading]

Distant Starburst Galaxy Pinpointed... and it has Companions

  An international team of astronomers led by Fabian Walter of the Max Planck Institute for Astronomy has managed for the first time to determine the distance of the galaxy HDF850.1, well-known among astronomers as being one of the most productive star-forming galaxies in the observable universe. The galaxy is at a distance of 12.5 [continue reading]

New SCUBA-2 camera reveals wild youth of the universe

A team of astronomers from the UK, Canada and the Netherlands have commenced a revolutionary new study of cosmic star-formation history, looking back in time to when the universe was still in its lively and somewhat unruly youth! The consortium, co-led by University of Edinburgh astrophysicist Professor James Dunlop, is using a brand new camera [continue reading]
