It seemed that these redshifted galaxies were all moving away from the Milky Way. Hubble’s results suggested the farther away a galaxy was, the faster it was moving away from Earth. Hubble got ...

By that metric, the ESA's Gaia mission is a resounding success. The spacecraft gave us a precise, 3D map of our Milky Way galaxy and has forced us to abandon old ideas and replace them with compelling ...

when researchers precisely measured the motions of many stars within the Andromeda Galaxy and found that these stars were approaching the Milky Way. Presently, the two galaxies are moving toward ...

The SAGA Survey’s extensive research across 101 galaxies similar to the Milky Way shows our galaxy may not be as typical as once thought, with significant implications for our understanding of dark ...

the Andromeda Galaxy will collide with the Milky Way, resulting in a spectacular cosmic collision! Don’t worry, though – the distances between stars are vast, so we won’t feel a thing.

In 2011, a project that surveyed the Milky Way galaxy for exoplanets — which are planets beyond our solar system — spotted an intriguing signal: They found two objects traveling together ...

One of the largest galaxies ever found, the behemoth is about 1.44 billion light-years away and reckoned to be 32 times the size of our Milky Way galaxy. The mightly object is classed as a giant ...

Astronomers have discovered an extraordinary new giant radio galaxy with plasma jets 32 times the size of our Milky Way. Measuring 3.3 million light-years from end-to-end, the cosmic megastructure ...

This fascinating region lies in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. A Star-Forming Marvel in the Universe The Tarantula Nebula is known for its active star formation.

The Milky Way keeps its planets close to its chest. Stars in a thin, flat disk bisecting the galaxy have more planets on average than stars in a thicker, enveloping disk — and astronomers now ...
