The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

To map out complex space trajectories, scientists rely on powerful numerical simulations—tools now central to the work of agencies like NASA and ESA. The recent discovery of comet 3I/Atlas offers a ...

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, ...

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star ...

When astronomers look deep into the early universe, the expectation is simple. You should see young galaxies still assembling ...

In the very young universe, just a fraction of its current age, astronomers have stumbled on a set of objects that refuse to ...

If you've ever poured milk into a cup of coffee and watched it swirl, you've seen turbulence in action. This phenomenon is responsible for everything from a bumpy airplane trip to ocean currents. Now, ...

The discovery of thousands more galaxies with stars ringing their main disks could help astronomers study galactic evolution ...

Astronomers have discovered a rare starless galaxy-like cloud known as a RELHIC, providing the strongest evidence yet for a cornerstone prediction of the Lambda CDM model: that many small dark matter ...

Gas within the cluster, which existed merely 1.4 billion years after the Big Bang, is at least five times hotter than ...
