While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and slowly ...

Webb witnessed a highly ionised gas whose level of energy was too high to come from something like supernovae, making ...

A blob of gas seen outside the Milky Way could be a type of starless, dark matter–dominated galaxy. Some scientists are skeptical.

If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.

A team of astronomers at the Space Telescope Science Institute, working with one colleague from the University of St Andrews' ...

The James Webb Space Telescope reveals turbulent environments found in Sagittarius C, a core part of our Milky Way galaxy.

Back when the Universe was new, following the Big Bang some 13.8 billion years ago, galaxies took a bit of time to assemble ...
