Astronomers say that there are hundreds of black holes in the group which is 20 times bigger than our sun. In the very core of a globular cluster of stars there may be hundreds of supermassive black holes, he wrote Science Alert. The star cluster under study is called Palomar 5. This star stream extends … Read more
A recent study suggests that black holes may have contributed to accelerating the birth of new stars during the first 50 million years of the universe Illustration of the magnetic field generated by a supermassive black hole in the early universeILLUSTRATION BY ROBERTO MOLAR CANDANOSA / JHU Enlarge image Astronomers believe that black holes formed … Read more
An artist’s vision of a boson star collision. Credit: Nicolas Sanchis Gual and Rocio Garcia Souto. With the advent of functional gravity observatories, a new window into space has opened for us. Thanks to it, we detect events that we could only dream about before. The problem is that we don’t always understand what gravity … Read more
The mystery continues: In 1952, a trio of stars suddenly disappeared. They did not appear again The Trinity That Disappeared. Credit: Palomar Observatory/Solano, et al. (2023). Sometimes things happen in space that baffle the minds of astronomers. An excellent example is the disturbing case of the missing trio of stars. One summer evening 71 years … Read more
This article was first published on Forskning.no Black holes don’t act like an always-on vacuum cleaner. Nor like a drain in a bathtub or a voracious hole in the ground. But we resort to comparisons with something we know when we think about and explain black holes. Space is beyond our imagination, so understanding something … Read more
Stephen Hawking predicted that black holes evaporate through a process related to the event horizon that gives rise to Hawking radiation. A team of Dutch physicists claims that similar evaporation also applies to objects that have no event horizon. If they are right, then the universe will die of boredom in an unimaginably long time. … Read more
