Some galaxies have a period of extremely rapid star formation, and this leads to their early demise.
Supermassive Black Holes Can Trigger Star Formation
Supermassive black holes lurk in the hearts of galaxies, and they can trigger the formation of new stars.
ALMA Sees Hydrogen Super-Halos Around Young Spiral Galaxies
New observations from ALMA show that early galaxies were surrounded by large halos of hydrogen gas.
ALMA Deep Field
ALMA has seen clues of star formation in some of the most distant galaxies.
A Bit Farther
The most distant galaxy yet has been observed with a redshift of z=11.1.
Some Galaxies Give Birth To 800 Stars Per Year
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.
The Galactic Main Sequence
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.
Did Stars Form In The Center Of Our Galaxy First?
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.
A Galaxy in the Making
New observations from ALMA show a galaxy in the making.
