The superbubble is gigantic, measuring around 210 by 140 light-years across.

The star passes very close to the Milky Way’s supermassive black hole and could reveal the black hole’s spin by tracking how ...

About two and a half million light years from Earth, the Andromeda Galaxy is not just a smudge of light in the night sky but ...

For centuries, scientists have puzzled over globular clusters, the dense star systems that orbit galaxies without dark matter. Using ultra-detailed simulations, researchers recreated their origins and ...

A star called S301 passes Sagittarius A* at 8% of light speed, near enough that the black hole's spin should bend its orbit.

The speedster travels at up to 56 million miles per hour, or about 8 percent the speed of light. It also gets very close to ...

Last week I mentioned we'd revisit the Milky Way to explore a little more. Sometimes it's difficult when looking at a ...

Inside-out growth and stellar migration in the Milky Way: Inside the star-forming disc (within ~12 kpc), abundant cold gas fuels continuous star formation, producing young stars. Beyond this break ...

A fascinating discovery has emerged from astronomers: evidence of a galaxy merger that occurred within our Milky Way. This merger, which transpired around 12 billion years ago, involved a dwarf galaxy ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds clues about when it formed and what the galaxy was like at the time. Over ...
