Using twin detectors of NSF’s Laser Interferometer Gravitational-wave Observatory (LIGO), astrophysicists with the LIGO-Virgo-KAGRA (LVK) Collaboration...
Solar System’s moons such as Europa or Enceladus have thin crusts over deep oceans while the planet Mercury has a thin crust over a large metallic core....
Astronomers using the MeerKAT Pulsar Timing Array, an international experiment that uses the MeerKAT Radio Telescope in South Africa, have uncovered further...
The principle idea behind a warp drive is that instead of exceeding the speed of light directly in a local reference frame, a ‘warp bubble’ could traverse...
New calculations reveal that pairs of supermassive black holes can merge into a larger black hole because of previously overlooked behavior of dark matter...
Astrophysicists from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Collaboration have found evidence for gravitational waves...
SSN 7 is a so-called contact binary located in the Small Magellanic Cloud, a dwarf galaxy some 210,000 light-years away in the constellation of Tucana....
In 2015, astrophysicists for the first time detected gravitational waves, ripples in space-time that occur when neutron star or black hole mergers disrupt...
Princeton Plasma Physics Laboratory physicists Deepen Garg and Ilya Dodin say they can better understand the state of the cosmos shortly after the Big...
This is the first time such an effect, known as precession, has been seen in black holes, where the twisting is 10 billion times faster than in previous...
The formation of ultrarare supermassive black holes, with masses over one billion solar masses, in the first billion years of the Universe is an open question...
Astrophysicists from the LIGO-Virgo-KAGRA Collaboration have detected a further 35 gravitational waves since the last catalog release in October 2020,...
Since the first observation of merging black holes in 2015, astrophysicists have been repeatedly surprised by their large masses. They originally expected...
The Andromeda galaxy is a barred spiral galaxy 2.5 million light-years from Earth. Otherwise known as Messier 31, it hosts a double nucleus, which is well-explained...
While most of the binary black-hole mergers recently detected by NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States...
Astronomers using NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States and by the Virgo detector in Italy have observed...
Gravitational-wave and electromagnetic observations of neutron-star-black-hole mergers can provide precise local measurements of the Universe’s rate...
Gravitational-wave detectors can be used to measure gravitational-field hair of extreme black holes, according to a paper published in the journal Physical...
