A Higgs-gravity connection may leave traces in white dwarfs
Astrophysicists find supermassive black holes in quasar nearest Earth
Astronomers using NASA's Hubble Space Telescope have found that Markarian 231 (Mrk 231), the nearest galaxy to Earth that hosts a quasar, is powered by two central black holes furiously whirling about each other.
Astronomers discover a tenth transiting "Tatooine"
Astronomers at the 29th International Astronomical Union General Assembly will announce on August 14 the discovery of a new transiting "circumbinary" planet, bringing the number of such known planets into double digits. A ...
Neutron stars strike back at black holes in jet contest
Some neutron stars may rival black holes in their ability to accelerate powerful jets of material to nearly the speed of light, astronomers using the Karl G. Jansky Very Large Array (VLA) have discovered.
Distant black hole wave twists like giant whip
Fast-moving magnetic waves emanating from a distant supermassive black hole undulate like a whip whose handle is being shaken by a giant hand, according to a new study using data from the National Radio Astronomy Observatory's ...
NASA simulation suggests black holes may make ideal dark matter labs
A new NASA computer simulation shows that dark matter particles colliding in the extreme gravity of a black hole can produce strong, potentially observable gamma-ray light. Detecting this emission would provide astronomers ...
Helium-shrouded planets may be common in our galaxy
They wouldn't float like balloons or give you the chance to talk in high, squeaky voices, but planets with helium skies may constitute an exotic planetary class in our Milky Way galaxy. Researchers using data from NASA's ...
Exiled stars explode far from home
Sharp images obtained by the Hubble Space Telescope confirm that three supernovae discovered several years ago exploded in the dark emptiness of intergalactic space, having been flung from their home galaxies millions or ...
Researchers identify circular orbits for 74 small exoplanets
Viewed from above, our solar system's planetary orbits around the sun resemble rings around a bulls-eye. Each planet, including Earth, keeps to a roughly circular path, always maintaining the same distance from the sun.
