Astronomers may have found the "perfect storm" for ending star formation.
It turns out that when it comes to creating new stars, a cool cosmic environment is the best policy. Scientists have discovered a surge of warm gas that flowed into a nearby galaxy extinguished star formation by agitating the available chilled gas.
For the first time, astronomers have witnessed the dramatic "blow out" phase of galactic evolution. They've discovered dense gas being blasted out of a compact galaxy at speeds of up to two million miles per hour.
Astronomers have managed to detect the faint signal emitted by atomic hydrogen gas in galaxies that are at record-breaking distances from Earth--a staggering three billion light-years.
Astronomers may have found an important new example of a rare type of galaxy. The new finding could help shed light on how galaxies first developed in the early universe.
The Herschel Space Observatory has taken a series of stunning images of the galaxy, Andromeda. The new images are the first time that astronomers have seen Andromeda in high-resolution infrared wavelengths.
The "Eye of Sauron" isn't just something that appears in The Lord of the Rings movies. Astronomers are now using a cosmic feature with the same namesake to measure precise distances to galaxies that are tens of millions of light-years away.
How do galaxies form and how do they evolve? How are they impacted by their surrounding environment? These are both good questions and now, astronomers have taken a closer look at the "cosmic web" of our universe in order to propose some answers.
New observations of globular clusters in a small galaxy, called Fornax, show that they are very similar to those found in the Milky Way, and so must have formed in a similar way.
Scientists have uncovered young, massive compact galaxies that are coming to an end of their intense bouts of star formation.
Astronomers have provided the first ever direct evidence that an intergalactic "wind" is stripping galaxies of star-forming gas as they fall into clusters of galaxies.
Scientists have found that a starburst galaxy, known as AzTEC-3, together with its gang of calmer galaxies may just represent the best evidence yet that large galaxies grow from the merger of smaller ones in the early universe.
