Astronomers map brightest galaxies and more in the news
A group of astronomers from the University of Hawaiʻi at Mānoa, the U.S. mainland, Canada, and Europe recently used the twin telescopes of the W.M. Keck Observatory on Mauna Kea to conduct a census of the brightest, but until now unseen, galaxies in the distant universe, bringing astronomers one step closer to understanding how galaxies form and evolve.
These galaxies glow so brightly at infrared wavelengths that they would outshine the Milky Way by hundreds, maybe thousands, of times. They are forming stars so quickly that between 100 and 500 new stars are born in each galaxy every year, and have been coined “starbursts” by astronomers.
While it’s not clear what gives these galaxies their intense luminosity, it could be the result of a collision between two spiral-type galaxies, similar to the Milky Way and Andromeda Galaxies. They could also be in a particularly gas-rich region of space, where galaxies form stars quickly due to constant bombardment from gas and dust.
