Some brown dwarfs rotate so fast that they are flattened spheres. If they rotate any faster they might fly apart.
The early asteroids had a similar size, and this could be due to turbulence in the early solar system.
An intermediate mass black hole was discovered by its chance alignment with a gamma ray burst.
A new look at the black hole in M87 tells us about the magnetic fields that drive its activity.
We could gravitationally lens radio signals to communicate with space probes at other stars. Maybe even communicate across the galaxy.
If magnetic monopoles exist, they might be found in Earth’s magnetic field. A new paper gives the first results of the search.
An alternative to general relativity predicts wormhole travel is possible, but only if you’re teeny-tiny.
A new look at warp drive fuels hope that it might be possible after all.
The smallest black hole we’ve observed might prove dark matter is made of primordial black holes.
