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]

Explosion of Galaxy Formation Lit Up Early Universe

  New data from the South Pole Telescope indicates that the birth of the first massive galaxies that lit up the early Universe was an explosive event, happening faster and ending sooner than suspected. The South Pole Telescope recorded temperature fluctuations in the cosmic microwave background, the light left over from the Big Bang, to [continue reading]

Fierce Galactic Winds from Starbursts End New Star Formation

  Fierce galactic winds powered by an intense burst of star formation may blow gas right out of massive galaxies, shutting down their ability to make new stars. Matter blasts out of the starburst galaxy M82 in this composite image from three observatories.
