Observations of a merging black hole further supports the Area Theorem of black hole thermodynamics, which states that the event horizon of a black hole produced by two merging black

Tracking down black holes at the center of dwarf galaxies has proven difficult. In part that is because they have a tendency to “wander” and are not located at the

Galaxies grow massive through mergers with other galaxies. Massive galaxies like the Milky Way and Andromeda not only merge with other large galaxies, they also absorb their much smaller satellite

All motion is relative. That simple fact makes tracking the motion of distant objects outside our galaxy particularly challenging. For example, there has been a debate among astronomers for decades

Let’s rewind the clock back…oh, I don’t know, let’s say a hundred years.

Observations of a supernova explosion have revealed its shape only one day after it was first detected. The exact nature of supernovae explosions are unclear and the subject of ongoing,
