LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars（图）
LIGO Virgo first detection gravitational waves produced colliding neutron stars
2017/10/26
For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first tim...

Gravitational Waves Space Make A Black Hole
2017/10/26
For the first time, scientists worldwide and at Penn State University have detected both gravitational waves and light shooting toward our planet from one massively powerful event in space -- the birt...
Gravitational waves carry information about their origins and about the nature of gravity that cannot otherwise be obtained. Physicists on the LIGO and Virgo teams concluded that, as with LIGO’s first...

Seeking to expand how we observe and understand the universe where we live, the National Science Foundation today helped dedicate the Advanced Laser Gravitational Wave Observatories (Advanced LIGO) at...
BICEP2 and Planck joint study: Gravitational waves remain elusive
BICEP2 Planck joint Gravitational waves remain elusive
2015/3/4
A new joint analysis of data from two South Pole-based experiments--the BICEP2 telescope and the Keck Array, both supported by the National Science Foundation--and the European Space Agency's Planck s...
Astronomers could be on the cusp of detecting gravitational waves after four decades of trying, according to a team of Polish astrophysicists. They say that if current gravitational-wave detectors are...
By combining observations at gamma-ray and radio wavelengths, astronomers have rapidly increased the known number of millisecond pulsars in the Milky Way. The newly discovered pulsars, found using NAS...
