Our planet is in constant flux: Weather, erosion, and plate tectonics mean Earth is never the same from one moment to the next. This is in stark contrast to the firmament above, a seeming paragon of ...

Galaxies start life with their stars rotating in an orderly pattern but in some the motion of stars is more random. Until now, scientists have been uncertain about what causes this—possibly the ...

The colors of the arrows represent the direction of motion. Relative to the LMC, located at the bottom left of the image, most red arrows show movement towards the LMC, whereas most light blue arrows ...

The Gaia space telescope has measured the acceleration of the Solar System when it orbits the center of our Milky Way galaxy. The Solar System motion relative to the stars agrees with the results by ...

A team has revealed new insights into the motion of massive stars in the Small Magellanic Cloud (SMC), a small galaxy neighboring the Milky Way. Their findings suggest that the gravitational pull of ...
