Odd behavior of star reveals lonely black hole hiding in giant star cluster
Jan 17, 2018
Astronomers using ESO's MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely. It appears to be orbiting an invisible black hole with about four ...
How massive can neutron stars be?
Jan 16, 2018
Astrophysicists at Goethe University Frankfurt set a new limit for the maximum mass of neutron stars: They cannot exceed 2.16 solar masses.
How we created a mini 'gamma ray burst' in the lab for the first time
Jan 15, 2018
Gamma ray bursts, intense explosions of light, are the brightest events ever observed in the universe – lasting no longer than seconds or minutes. Some are so luminous that they can be observed with the naked eye, such ...
Black hole spin cranks-up radio volume
Jan 12, 2018
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves and other radiation across the universe.
Researchers catch supermassive black hole burping—twice
Jan 11, 2018
A team led by CU Boulder researchers has caught a supermassive black hole in a distant galaxy snacking on gas and then "burping"—not once, but twice.
Scientists take viewers to the center of the Milky Way
Jan 10, 2018
A new visualization provides an exceptional virtual trip—complete with a 360-degree view—to the center of our home galaxy, the Milky Way. This project, made using data from NASA's Chandra X-ray Observatory and other telescopes, ...
Black hole breakthrough: New insight into mysterious jets
Jan 10, 2018
Through first-of-their-kind supercomputer simulations, researchers, including a Northwestern University professor, have gained new insight into one of the most mysterious phenomena in modern astronomy: the behavior of relativistic ...
How massive is Supermassive? Astronomers measure more black holes, farther away
Jan 10, 2018
Today, astronomers from the Sloan Digital Sky Survey (SDSS) announced new measurements of the masses of a large sample of supermassive black holes far beyond the local Universe.
Black hole research could aid understanding of how small galaxies evolve
Jan 09, 2018
Scientists have solved a cosmic mystery by finding evidence that supermassive black holes prevent stars forming in some smaller galaxies.
