Black hole pics side-by-side. M87 is more massive than Sagittarius A.
According to a new report, the Chinese booster will hit the moon.

Three years ago, a telescope the size of Earth was used to produce the first ever image of a black hole. They did it again, this time closer to home, and of a very different invisible monster.
The M87 black hole in the center of a galaxy is one of two black holes that have been photographed by the EHT. Hundreds of scientists involved in the endeavor have gotten their first glimpse of two objects that are very different.
The two images appear very similar to us when we look at them in the sky, according to Feryal, an astronomer at the University of Arizona.
The black hole discovery in the Milky Way is depicted in photos.
The black holes differ in how difficult it is to see material moving around a horizon. The material that lights up the fuzzy rings the EHT has labored to produce is what the black holes themselves do not emit light.
The less challenging target was tackled first by the EHT. The monster is hidden within M87, also known as M87*. The black hole is larger and more active than the Earth, and material moves at a more leisurely pace.
During the news conference, a member of the science council said that material swirls around M87 over the course of many days.
Sagittarius A* is less cooperative than the other black holes.
There are 8 ways we know that black holes exist.
Scientists analyzed the data gathered by the EHT as well as Sagittarius A*. When the independent teams that formed to analyze the M87 results compared their first takes at an image, they were more or less the same, according to a computer scientist at the California Institute of Technology.
The second black hole was a messier story than the first. The groups were reluctant to produce an initial image because they didn't have the same amount of consensus.
The material surrounding Sagittarius A* is moving very fast, but our black hole has a much tamer environment near its surface. The turbulence in this region is determined by the appetite of the black hole, despite the popular belief that all black holes have the same appetite.
If Sagittarius A* were a person, it would consume a single grain of rice every million years, according to Michael Johnson, an astronomer at the Harvard/Smithsonian Center for Astrophysics.
Sagittarius A* is a dainty eater and its environment is relatively gentle because of that.
Sagittarius A* is an important challenge to tackle, as it is giving us a view into the more standard state of black holes. Sagittarius A* is exciting because it is common.
At a glance, the new portrait of Sagittarius A* might be mistaken for the one released in 2019.
The bright ring surrounding the black hole shadow is caused by fundamental forces of gravity.
It is still tempting to have fun with the similarity, but it is physics.
