About 250 million light-years away, there’s a neighbourhood of our universe that astronomers had considered quiet and unremarkable. But now, scientists have uncovered an enormous, bizarre galaxy possibly formed from the parts of other galaxies. Some 718,000 light-years across, UGC 1382 is more than seven times wider than the Milky Way.
You can never predict what treasure might be hiding in your own basement. A researcher looking for a spectrum of a white dwarf known as van Maanen’s star found a 1917 image on an astronomical glass plate from the Carnegie Observatories’ collection that shows the first-ever evidence of a planetary system beyond our own Sun.
Leading scientists, senior officials, and representatives of an international consortium of universities and research institutions gathered on a remote mountaintop high in the Chilean Andes to celebrate groundbreaking for the Giant Magellan Telescope (GMT). The instrument is poised to become the world’s largest telescope when it begins early operations in 2021.
Collaborators secure more than $500 million for the historic $1 billion project to build the Giant Magellan Telescope — a seven-mirror colossus gathering more than six times the amount of light of the current largest optical telescopes into images up to 10 times sharper than those of the Hubble Space Telescope.
