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.
Scientists were surprised to find that this tenuous, nearly invisible halo of diffuse plasma extends 1.3 million light-years from the Andromeda galaxy and as far as 2 million light-years in some directions.
Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, astronomers estimates the age of the universe at 12.6 billion years, different to the value of 13,8 billion years.
The prominent X-shape of PKS 2014-55 is made up of two pairs of giant lobes consisting of hot jets of electrons. These jets spurt outwards from a supermassive black hole at the galaxy's heart.
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.
The universe is full of billions of galaxies. Why do we see so much structure in the universe today? A 10-year survey of tens of thousands of galaxies has provided a new approach to answering this fundamental mystery.
30 years ago the Hubble Space Telescope blasted off the launch pad aboard the space shuttle Discovery, ushering in a new era for astronomy that has transformed our understanding of the Universe around us.
A new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.
