Our nearest stellar neighbor may have a habitable world

If Earth needs to borrow a cup of sugar, it's comforting to know that there may be a convenient, possibly habitable, world orbiting Alpha Centauri only 4.34 light years away – at least, if the ...

Astronomers are shocked to find our galaxy's nearest neighbor is being torn to shreds

An analysis of star movements from the Gaia spacecraft reveals that the Small Magellanic Cloud — a satellite galaxy bound to the Milky Way — is being torn apart by its larger neighbor. When you ...
