A Separate Star Cluster Found in Front of the Orion Nebula Cluster

  Using images from the 340 Mpx MegaCam camera on the Canada-France-Hawaii Telescope (CFHT) from the summit of Mauna Kea, astronomers identified the massive cluster of young stars NGC 1980 to be a clearly separate entity from the main cluster of the most studied star formation region in the Galaxy. A technique relying on the [continue reading]

Star Clusters in the Tarantula Nebula on a Collision Course

  Astronomers using data from NASA’s Hubble Space Telescope have caught two clusters full of massive stars that may be in the early stages of merging. The clusters are 170,000 light-years away in the Large Magellanic Cloud, a small satellite galaxy to our Milky Way. This is a Hubble Space Telescope image of a pair [continue reading]
