This image from the NASA/ESA Hubble Space Telescope reveals a glistening and ancient globular cluster named NGC 3201 — a gathering of hundreds of thousands of stars bound together by gravity.
How an international team of researchers is constraining the speed of invisible and undetectable dark matter
Scientists on the hunt for colliding black holes should turn their eyes to the quiet, outer regions of galaxies like the Milky Way, a new study suggests.
A new study of a nearby cluster of newly formed stars reveals that brown dwarfs may rival stars in the Milky Way in number, with one brown dwarf for every two bona fide stars.
Einstein’s greatest theory has aced another test. Two stars are speeding around the big black hole at the Milky Way’s core in just the way his general theory of relativity predicted.
An international team of astronomers, led by Dutch scientists, has discovered a region in our Milky Way that contains many nitrogen compounds in the southeast of a butterfly-shaped star formation disk and very little in the north-west.
A team of international astrophysicists led by The Australian National University (ANU) has shown how most of the antimatter in the Milky Way forms.
Images taken by NASA’s New Horizons mission on its way to Pluto, and now the Kuiper Belt, have given scientists an unexpected tool for measuring the brightness of all the galaxies in the universe, said a Rochester Institute of Technology researcher in a paper published this week in Nature Communications.
