In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.
James Webb Space Telescope has captured light emitted by the galaxies more than 13.4 billion years ago, which means the galaxies date back to less than 400 million years after the Big Bang, when the universe was only 2 % of its current age.
Scientists have proved that the source of high-energy neutrinos is a special kind of supermassive black holes called blazars.
NASA's James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb'nas First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.
More than three years after the release of the first-ever image of a black hole, scientists from the Event Horizon Telescope (EHT) shared an image of Sagittarius A* — the supermassive specimen sitting at the center of our own Milky Way galaxy.
Astronomers completed a 40-hour long observation of an ultra-diffuse dwarf galaxy and discovered no traces of dark matter. Galaxies without hints of dark matter had been previously discovered though these remain rare anomalies.
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.
A team of U.S. astronomers have created the Pan-STARRS1 Source Types and Redshifts with Machine Learning (PS1-STRM), the world’s largest three-dimensional astronomical catalog.
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.
Images of the Milky Way, California nebula and Andromeda galaxy are among the winners of the Insight Investment astronomy photographer of the year award.
