Black hole

There is a black hole at the center of our universe.

The EHT collaboration is happening.

The black hole at the center of the Milky Way has never been seen in such detail before. This is the first direct image of the giant Sagittarius A*. The black hole's shadow is shown against a background of hot plasma that is falling in.

The image was taken by the event horizon telescope, a network of radio observatories spread around the globe that operate as a single, enormous telescope The first image of a black hole was created by the EHT in the year 2019.

The analysis of the data that made up both of these images was much more difficult for Sagittarius A*. Sagittarius A* is one-thousandth the mass of M87*, so the plasma spiralling into it is much closer in and moves quickly. The team may eventually be able to make a video of how Sagittarius A* changes over time.
