Astronomers looking at the core of the Milky Way have discovered some of the most extreme stars in our galaxy. Orbiting the central supermassive black hole known as Sagittarius A*, one of these stars is now the fastest ever discovered in the galaxy, moving at around 8 percent of the speed of light.
Hypothetical tunnels in spacetime could show up in LIGO and Virgo data
Despite the vast numbers of galaxies we can study, astronomers have struggled to make sense of their evolution. In particular, there is the question of what causes some galaxies to “die”, ceasing star formation, but the galactic structure and black hole size may provide an answer.
Amir Siraj and Professor Avi Loeb from the Department of Astronomy at Harvard University have developed a new method to search for primordial black holes in the outer Solar System, based on accretion flares that result from impacts of small bodies from the Oort Cloud.
Black holes aren’t supposed to make flashes of light. It’s right there in the name: black holes.
The second-most distant quasar ever discovered now has a Hawaiian name
A 50-year-old theoretical process for extracting energy from a rotating black hole finally has experimental verification.
Streams of plasma shooting away from galaxies flare at the ends
A black hole burp filled the Milky Way’s center with mysterious invisible structures, a new study suggests.
If true, this would be only the second time such a neutrino has been traced back to its source
