"The study opens up new frontiers in our understanding of the galactic halo and will help our knowledge of the Milky Way's complex and impetuous star-forming ecosystem." More information ...

New research from the SAGA Survey, comparing the Milky Way with 101 similar galaxies, unveils how our galaxy differs ...

showing that the size of the LMC's halo is around ten times smaller than halos of other galaxies that have the LMC's mass, which hints at a past incident with the Milky Way in which our galaxy ...

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small ...

That’s almost half the distance to Andromeda. This illustration shows the Milky Way galaxy's inner and outer halos. A halo is a spherical cloud of ... [+] stars surrounding a galaxy. Astronomers ...

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

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 ...

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 ...

Einstein predicted that massive objects bend light as it passes through their gravitational field. This week, a new telescope ...

Observations show Andromeda has a more active star formation history than the Milky Way, potentially due to a past galactic collision. NASA recently released images of the Andromeda galaxy ...
