Huge black holes events in 2020 … from the Nobel Prize to the discovery of the nearest hole


Last year is the golden year of black holes, as it was marked by several very important events in the history of space in general and black holes in particular. The events included a number of scientists winning the Nobel Prize for black holes, as well as the detection of the closest black hole ever observed, in addition to To several other events.

The Nobel Prize in Physics goes to black holes

The Nobel Prize, the most important scientific achievement, was awarded in October to three physicists whose work revealed the life of these mysterious cosmic entities. Roger Penrose, of the University of Oxford in the United Kingdom, received half the prize for his discovery that the formation of a black hole is a strong prediction of the theory of general relativity. While Andrea Geese of the University of California, Los Angeles, and Reinhard Genzel of the University of Bonn and the Max Planck Institute for Extraterrestrial Physics in Germany, they partnered the other half to discover a compact, supermassive object at the center of our galaxy, according to the Royal Swedish Academy of Sciences.

Jesse is only the fourth woman to ever receive a Nobel Prize in Physics, after Marie Curie in 1903, Maria Joybert Mayer in 1963, and Donna Strickland in 2018.

The closest black hole ever detected

Nobody wants to get closer to a black hole because of the danger it poses, and fortunately, the cosmic Pac-Man hole seen in May orbiting with a pair of companion stars known as HR 6819 is located an astronomically safe distance from its partners.

The newly discovered black hole lies 1,000 light-years from Earth in the Southern constellation Telescope, and is three times closer than the previous record holder.

Astronomers could not directly observe the black hole, but they were able to infer its existence based on how its gravitational influence on the other two objects in the system and their rotation in their orbits.

A treasure trove of black holes

The collaboration agency that oversaw LIGO and its European counterpart, Virgo, has released a new, ample catalog of dozens of detected gravitational-wave signals, as the 39 events contained many interesting findings, such as the massive black hole merger that produced the remaining 142 solar masses.

It also revealed a UFO that appeared to be a small black hole or large neutron star, and the researchers were happy with the data, which showed that the facilities were capturing on average one new signal every five days, and planning to use it to better understand the behavior and frequency of black hole merging.
