Star with the shortest orbital period around black hole discovered

The fastest known star, discovered by researchers at the University of Cologne and Masaryk University in Brno (Czech Republic), travels around a black hole in record time. S4716 orbits Sagittarius A*, the black hole at the centre of our Milky Way, in four years...

The puzzling link between star formation and radio emission in galaxies

On the 50th anniversary of the discovery of a close relationship between galaxies' star formation and their infrared and radio radiation, researchers at the Leibniz Institute for Astrophysics Potsdam (AIP) have now deciphered the underlying physics. They used novel computer simulations of galaxy formation...

Researchers find eight new sources of 4.7 GHz OH masers in northern star formation regions

National Time Service Center (NTSC) of the Chinese Academy of Sciences (CAS), Shanghai Astronomical Observatory (SHAO) of CAS and SKA Observatory researchers have used the Shanghai Tianma Radio Telescope to search for 4.7 GHz OH masers in 155 northern star forming regions. They discovered...

Simulating supernova remnants star formation in earthbound lab

Molecular clouds are collections of gas and dust in space. The clouds remain in their state of peaceful equilibrium, when left alone. Shockwaves can propagate through the gas and dust to create pockets of dense material, when triggered by some external agent. The dense...

Astrophysicists theorize a new type of neutron star

Scientists have proposed the existence of a new type of neutron star. The study was published in the journal Physical Review Letters. Scientists suggested that an exotic type of neutron star could be created if there is an ultra-strong magnetic field created during a collision...

Discovery of mysterious circular ring points to intergalactic origin

Western Sydney University researchers have discovered a mysterious circular ring near our neighboring galaxy. It could be the first known case of an intergalactic supernova remnant. This is the remains of an exploded star that could be up to 7,000 years old. It is most...
