Dwarf Galaxy Caught Ramming Into a Large Spiral

  Observations with NASA’s Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree gas in a galaxy about 60 million light-years from Earth. The hot gas cloud is likely caused by a collision between a dwarf galaxy and a much larger galaxy called NGC 1232. If confirmed, this discovery would mark the first time [continue reading]

Huge Supply of Pristine Gas around Modern Galaxies Found

  Galaxies have a voracious appetite for fuel — in this case, fresh gas — but astronomers have had difficulty finding the pristine gas that should be falling onto galaxies. Now, scientists have provided direct empirical evidence for these gas flows using new observations from the Hubble Space Telescope. The team led by Nicolas Lehner, [continue reading]

Nearby Dwarf Galaxy and Possible Protogalaxy Discovered

  Peering deep into the dim edges of the distorted Pinwheel Galaxy in the constellation Ursa Major (the Great Bear), astronomers at Case Western Reserve University and their colleagues have discovered a faint dwarf galaxy and another possible young dwarf caught before it had a chance to form any stars. The Pinwheel Galaxy. Image Credit & [continue reading]
