How can some galaxies survive with so few stars? The answer could be dark matter.
Some galaxies have a period of extremely rapid star formation, and this leads to their early demise.
Supermassive black holes lurk in the hearts of galaxies, and they can trigger the formation of new stars.
New observations from ALMA show that early galaxies were surrounded by large halos of hydrogen gas.
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.
