If everyone gave names to 200 galaxies, there would still be billions of nameless galaxies in the cosmos.
ALMA has seen clues of star formation in some of the most distant galaxies.
A new galaxy has been discovered that was hiding in plain sight.
The most distant galaxy yet has been observed with a redshift of z=11.1.
Recent observations from the ALMA radio telescope array have found some galaxies are extremely efficient at producing new stars, with some galaxies creating stars at an average rate of 800 per year.
If you plot galaxies by the estimated number of stars they have and the calculated rate at which stars are forming, then you find that most galaxies lie along a line.
One popular model of galaxy formation has been that stars form in the central region of a galaxy first, and then later stars further out form.
Astronomers have used a lens bigger than a galaxy to observe the faintest and youngest galaxies ever found.
A candle that burns twice as bright burns half as long, so the saying goes. We’ve thought of galaxies in the same way, in that the brightest galaxies (ones with high rates of star production) are likely in a cosmologically brief period of high activity. But new computer models suggest that might not be the case.
