A Milky way star cluster seems to contain more than the name suggests. How do astronomers find black holes hiding amongst stars?
How deep is an exoplanet’s ocean?
Astronomers model oceans outside of our Solar system and explore exotic planets.
Reconstructing the Galactic merger history with machine learning
Astronomers use machine learning to reconstruct past mergers that the Milky Way experienced.
A supercomputer made of idle CPUs rewinds stellar streams
Astronomers connect volunteered computers on MilkyWay@home and model the dark matter content of dwarf galaxies.
Finding fire-breathing dragons in the Milky Way
Dark matter subhalos are invisible and hard to detect, but astronomers in today’s paper use stellar streams to take a stab.
