Scientists have solved a befuddling mystery about the X-ray light coming from the sun.
Astronomers have put together an amazing new image of elliptical galaxy Hercules A.
Scientists will report on a population of primitive galaxies that formed more than 13 billion years ago.
The surprising answers delivered in the streets of Cadiz, Spain and Cologne, Germany led to this informative explanatory video.
A small galaxy named 2MASXI J0224301-244443 ripped through the center of galaxy NGC 922 around 330 million years ago. The collision disrupted clouds of gas and triggered the formation of new stars.
Many binary systems spread across vast distances could host a third star in their center.

An eruption of matter from a quasar could show how galaxies shed weight.
The massive exoplanet is just 100 light-years from Earth.
This beautiful space wallpaper shows the central parts of the starburst galaxy NGC 1313. The very active state of this galaxy is very evident from the image, showing many star formation regions.
This space wallpaper reveals an almost-true colour composite based on images made with the multi-mode VIMOS instrument on the 8.2-m Melipal (Unit Telescope 3) of ESO's Very Large Telescope.
This quasar is the most distant yet found and is seen as it was just 770 million years after the Big Bang in this space wallpaper.
This stunning space wallpaper shows the beautiful edge-on spiral galaxy NGC 3190 with tightly wound arms and a warped shape that makes it resemble a gigantic potato crisp, as seen by ESO's Very Large Telescope.
Fleming 1 is a rare planetary nebula enclosing a binary pair of white dwarf stars (typically these shells of gas surround only one white dwarf). The fast orbit of these stars creates two nearly symmetric jets that make Fleming 1 atypical.
In DC's Action Comics 14, the renowned astrophysicist helps Superman track down his home planet. By looking at the facts of this run of the comic he found a similar real Universe red dwarf solar system that the Man of Steel can call home.
Whether big or small, stars mostly form the same way; stellar gasses accumulating and slowly condensing until a fusion reaction is started. However, stars can die in different way, from super nova explosions to slow, steady decay.
Stars are being born today at just 3 percent the rate of the universe's long-ago peak.
