New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds ...

Four near-Earth asteroids are set to make close approaches to Earth within a 24-hour period, NASA’s Jet Propulsion Laboratory (JPL) has confirmed. Scientists stress that all four objects will pass ...

The Earth's planetary defenses will observe an interstellar comet flying through the Solar System, the United Nations has ...

Research published Tuesday by a Japanese astrophysicist says gamma rays may have been generated by the collision of dark ...

Simulating a billion years using previous best-resolution simulations would take almost 36 years of real computing time. The most detailed supercomputer simulation ever of our Milky Way galaxy has ...

Dark centre? A simulated version of the Milky Way galaxy. (Courtesy: AIP/ A. Khalatyan) Astronomers have long puzzled over the cause of a mysterious “glow” of very high energy gamma radiation ...

Researchers have successfully performed the world's first Milky Way simulation that accurately represents more than 100 billion individual stars over the course of 10 thousand years. This feat was ...

Head-on (left) and side-view (right) snapshots of a galactic disk of gas. These snapshots of gas distribution after a supernova explosion were generated by the deep learning surrogate model.

Even before its full science operations have begun, the Vera C. Rubin Observatory in Chile has already helped astronomers find something remarkable. The observatory's first images, revealed in June, ...

We cannot see or image the entire Milky Way galaxy, because we are located inside it. From Earth, we can observe only a portion of the galaxy, and when we look up at the dark, clear night sky from a ...

So it’s confession time: I’ve been lying to you. I’ve said on many occasions that our Milky Way galaxy has a flat disk (like in this column or this one). But it’s not really flat—not even for a ...
