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 ...

The consortium running the European Space Agency's (ESA) Euclid mission has published the most extensive simulation of the cosmos to date. The modeling was based on algorithms developed by UZH ...

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, ...

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

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

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 ...
