On Jan. 15, 2025, the Gaia spacecraft took its last image. Then the craft ran a final round of engineering tests, fired its thrusters to leave Earth behind, and slipped into an orbit around the Sun, ...

The Milky Way is a spiral galaxy containing 100-400 billion stars. Planet Earth sits along one of the galaxy’s spiral arms. Though the Milky Way is generally always visible from Earth, certain times ...

Add Yahoo as a preferred source to see more of our stories on Google. Milky Way is bringing back a previously discontinued fan-favorite with a new look and a new name, but all the same ingredients as ...

For ages, mapping the precise architecture of our home galaxy has been a challenge similar to attempting to draw a complete map of a vast, brightly lit city while standing trapped in the dense, hazy ...

Researchers combined deep learning with high-resolution physics to create the first Milky Way model that tracks over 100 billion stars individually. Their AI learned how gas behaves after supernovae, ...

Created using data from two extensive surveys, this spectacular radio image of the galactic plane of the Milky Way provides valuable insights into the birth and death of stars. When you purchase ...

Well, it’s confession time: I’ve been lying to you. I’ve said on many occasions in this column that our Milky Way galaxy has a flat disk. But it’s not really flat—not according to any reasonable ...

The Milky Way is a rich and complex environment. We see it as a luminous line stretching across the night sky, composed of innumerable stars. But that’s just the visible light. Observing the sky in ...

Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long ...

Johns Hopkins researchers may have identified a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

The Milky Way galaxy is like a gigantic ocean gyre or eddy that spins and wobbles around its center. But our home galaxy also has a colossal wave rippling through it, pulling and pushing an ocean of ...
