Can one cosmic enigma help solve another? Astrophysicists argue fast radio bursts could provide clues to dark matter
Aug 24, 2016
Astrophysicists from the Johns Hopkins University have proposed a clever new way of shedding light on the mystery of dark matter, believed to make up most of the universe.
Will our black hole eat the Milky Way?
Aug 16, 2016
Want to hear something cool? There's a black hole at the center of the Milky Way. And not just any black hole, it's a supermassive black hole with more than 4.1 million times the mass of the Sun.
Physicist claims to have observed quantum effects of Hawking radiation in the lab for the first time
Aug 16, 2016 report
(Phys.org)—Jeff Steinhauer, a physicist at the Israel Institute of Technology, has published a paper in the journal Nature Physics describing experiments in which he attempted to create a virtual black hole in the lab in ...
Ten trillionths of your suntan comes from beyond our galaxy

Lie on the beach this summer and your body will be bombarded by about sextillion photons of light per second.
A black hole story told by a cosmic blob and bubble
Aug 10, 2016
Two cosmic structures show evidence for a remarkable change in behavior of a supermassive black hole in a distant galaxy. Using data from NASA's Chandra X-ray Observatory and other telescopes, astronomers are piecing together ...
How a star cluster ruled out MACHOs
Aug 10, 2016
Are massive black holes hiding in the halos of galaxies, making up the majority of the universe's mysterious dark matter? This possibility may have been ruled out by a star cluster in a small galaxy recently discovered orbiting ...
Physicists prepare to detect gravitational waves from neutron star collisions
Aug 02, 2016 feature
(Phys.org)—Last February, scientists made the groundbreaking discovery of gravitational waves produced by two colliding black holes. Now researchers are expecting to detect similar gravitational wave signals in the near ...
The aligned spin of a black hole
Aug 01, 2016
A black hole in traditional theory is characterized by having "no hair," that is, it is so simple that it can be completely described by just three parameters, its mass, its spin, and its electric charge. Even though it may ...
Chorus of black holes radiates X-rays
Jul 28, 2016
Supermassive black holes do not give off any of their own light, hence the word "black" in their name. However, many black holes pull in, or accrete, surrounding material, and emit powerful bursts of X-rays. Collectively, ...
Did the LIGO gravitational waves originate from primordial black holes?
Jul 27, 2016
Binary black holes recently discovered by the LIGO-Virgo collaboration could be primordial entities that formed just after the Big Bang, report Japanese astrophysicists.
