Astronomers trace the Small Magellanic Cloud’s unusual stellar motions to a past cosmic encounter.

A galaxy neighbouring ours is transforming in unexpected ways – and it could change our view of space, researchers say. The Small Magellanic Cloud, or SMC, is one of the closest neighbours to our ...

Earth is not only orbiting the Sun it is also traveling through the Milky Way on an enormous galactic journey. In this video ...

Astronomers have discovered a flattened structure of matter around the Milky Way that explains the unusual motion of nearby galaxies.

The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors—a small, gas-rich galaxy visible to the ...

A new image from the European Southern Observatory reveals a gas cloud orbiting the Milky Way’s central black hole, offering details on its structure and motion.

Earth’s gravity has a lot to do with what people think is up and what is down. Things fall down toward the ground, but that direction depends on where you are.

The Sun has been a powerful source of energy fueling the solar system for billions of years, but our host star may have had rough beginnings. A new study suggests the Sun migrated away from the center ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about ...

Astronomers produced the most complete map of the center of the Milky Way, which can provide insight into how stars and planets are formed.

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a ...
