For billions of years before reaching its current location, the Sun may have slowly travelled as part of a large group, or “wave,” of stars drifting out from the inner parts of the Milky Way. This ...

A nearby galaxy is behaving strangely—and now scientists know why. The Small Magellanic Cloud’s stars move in chaotic ...

Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of ...

A new study suggests the Sun moved outward with many similar stars during a large Milky Way migration event long ago.

The Gaia telescope spotted more than 6,000 sunlike stars, all of which appear to have migrated from the galaxy's center more ...

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

The Andromeda Galaxy, the nearest major galaxy to the Milky Way, is slowly moving toward us at incredible speed. Astronomers know that in roughly four billion years the two galaxies will collide and ...

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

The European Space Agency’s Gaia space telescope spent more than a decade mapping the Milky Way, collecting over 3 trillion observations of nearly 2 billion stars. When scientists analyzed the data, ...

Scientists have captured the most complete, high-resolution map of the cold gas at the center of the Milky Way, which contains the raw material from which stars and planets are made. Information from ...

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 ...

Meteorologists divide our planet’s annual seasons, referred to as “meteorological seasons”, into four equal divisions of ...
