New research has just answered one of the fundamental questions about our universe: Why did some of the oldest, most massive galaxies go quiescent early in their formation? The answer, we now know, is because they ran out of cold gas.
For the first time, astronomers have just found evidence that some of the largest structures in space - cosmic filaments - rotate, on a scale of hundreds of millions of light-years.
FRBs are powerful jets of energy that has mysterious origins. The research team performed a survey of eight FRBs, from which they were able to determine that five of them originated from a spiral arm in their host galaxies.
The survey, which included 400 individual scientists from 25 institutions in 7 countries, observed over 226 million galaxies. The goal of the survey was to the distribution of dark matter and the effect of dark energy.
Astronomers have spotted two close pairs of quasars in the process of merging as their host galaxies crash together in a slow-motion collision 10 billion years ago. Quasars make a profound impact on galaxy formation.
Astronomers have discovered the most distant source of radio emission known to date - the quasar, nicknamed P172+18. It is so distant that light from it has travelled for about 13 billion years to reach us.
Astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. This is the first time such a close grouping has been seen so soon after the Big Bang.
Giant elliptical galaxies are not as likely as disk-shaped galaxies, such as our own Milky Way, to be cradles of technological civilizations, according to a recent U.S. paper.
