The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, ...

New simulations suggest that dozens of ultra-faint “ghost” galaxies may be orbiting the Milky Way, hidden from current ...

A newfound stream of stars is all that's left of a smaller galaxy recently gobbled by the Milky Way, a new study says.

There may be many more satellite galaxies in the Milky Way than have been observed, according to new Durham University ...

A massive star suddenly disappeared from a dwarf galaxy, and astronomers are not quite sure what happened.

The center of the nebula is home to the white dwarf WD 2226-210, the dense core of a medium-mass star, which has been the source of an astronomical mystery for decades. Observations from the ...

In the constellation Aquarius, invisible to the naked eye, lies a star that might change history. Home to seven mysterious planets—each around the size of our own Earth—the TRAPPIST-1 system ...

To celebrate its 25th anniversary, the Gemini North telescope team has released a stunning image of starburst galaxy NGC 4449, which is ablaze with intense star birth as it devours smaller galaxies.

Residing only roughly 700 light-years from Earth in the constellation Aquarius, R Aquarii is a symbiotic binary star: a type of binary star system consisting of a white dwarf and a red giant that ...

The object's brightness might have dipped because it is partially obscured by dust. It is located some 75 million light-years away in the Kinman Dwarf galaxy, in the constellation of Aquarius.

Most galaxies in the Universe are low-mass dwarf galaxies, the majority of which are satellites orbiting around a more massive galaxy, such as our Milky Way.
