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]

Wow! Dark Galaxies of the Early Universe Spotted

  For the first time, dark galaxies — an early phase of galaxy formation, predicted by theory but unobserved until now — may have been spotted. These objects are essentially gas-rich galaxies without stars. Using ESO’s Very Large Telescope, an international team thinks they have detected these elusive objects by observing them glowing as they [continue reading]

 GOODS-Herschel reveals gas mass role in creating fireworks versus beacons of star formation

A study of galaxies in the deepest far-infrared image of the sky, obtained by the Herschel Space Observatory, highlights the two contrasting ways that stars formed in galaxies up to 12 billion years ago. Dr Georgios Magdis will present the results at the National Astronomy Meeting in Manchester. False colour image of BzK-21000 from the [continue reading]
