Scientists star-shredding event origins universe highest-energy particles
2021/3/5
A team of scientists has detected the presence of a high-energy neutrino -- a particularly elusive particle -- in the wake of a star's destruction as it is consumed by a black hole.The discovery is a ...
New observations of black hole devouring a star reveal rapid disk formation(图)
New observations black hole devouring star rapid disk formation
2020/9/11
When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...
Even 'Goldilocks' exoplanets need a well-behaved star(图)
Goldilocks exoplanets well-behaved star
2019/11/15
An exoplanet may seem like the perfect spot to set up housekeeping, but before you go there, take a closer look at its star.Rice University astrophysicists are doing just that, building a computer mod...
Astronomers see evidence of Einstein's theories in star orbiting massive black hole(图)
Astronomers evidence Einstein theories star orbiting massive black hole
2019/10/22
More than 100 years ago, Albert Einstein predicted that light is deflected by extremely massive objects, but there is no way to test such powerful effects on Earth. Instead, astronomers turn their att...
On April 25, NSF's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears to be a crash between two neutron s...

An international team of astronomers has produced the first detailed images of the surface of a giant star outside our solar system, revealing a nearly circular, dust-free atmosphere with complex area...
Supermassive Black Holes Control Star Formation In Large Galaxies(图)
Supermassive Black Holes Control Star Formation Large Galaxies
2018/1/10
Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy evolves. A new study, published January 1, 2018, in Nature, shows that the mass...
