The binary neutron-star merger GW170817 was discovered in August 2017. Many telescopes saw different kinds of light after the discovery, but only NASA’s...
Astronomers using the Murchison Widefield Array (MWA) telescope have discovered a spinning object that pulses every 18.18 minutes; they’ve localized...
The giant gamma-ray flare event, designated GRB 2001415, was emitted by a powerful magnetar in NGC 253, an active starburst galaxy approximately 11 million...
Astrophysicists from the LIGO-Virgo-KAGRA Collaboration have detected a further 35 gravitational waves since the last catalog release in October 2020,...
Because of their compactness, neutron stars have an enormous gravitational pull around a billion times stronger than the Earth. This squashes every feature...
Astronomers using NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States and by the Virgo detector in Italy have observed...
Astronomers using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) have discovered 201 pulsars, including currently the faintest pulsars...
Gravitational-wave and electromagnetic observations of neutron-star-black-hole mergers can provide precise local measurements of the Universe’s rate...
Astronomers using the Murchison Widefield Array (MWA), a low-frequency radio telescope in Australia, have discovered a new long-period, low-luminosity...
Using the Low-Frequency Array (LOFAR), astronomers from the Canadian Hydrogen Intensity Mapping Experiment (CHIME) have found that fast radio bursts include...
Located 6,500 light-years away in the constellation of Taurus, the Crab Nebula and its pulsar formed in a supernova whose light reached Earth in July 1054;...
Supernova 1987A (SN 1987A) was first observed on February 23, 1987 in a nearby dwarf galaxy, the Large Magellanic Cloud, some 164,000 light-years away....
Using data from NASA’s Fermi Space Telescope and the enormous computing power of the citizen science project Einstein@Home, astronomers have found that...
First theorized in the 1970s, axions are hypothetical particles that were proposed to preserve a time-reversal symmetry of the nuclear force. These particles...
A massive star exploded in the Small Magellanic Cloud between 2,000 and 1,000 years ago and left behind an expanding, gaseous remnant called 1E 0102.2-7219....
Astronomers using NASA’s Chandra X-ray Observatory have studied Swift J1818.0-1607, a new magnetar (a type of neutron star with an extremely powerful...
Whenever two compact objects (black holes or neutron stars) collide elsewhere in the Universe, they create gravitational waves that travel across space,...
Astronomers have detected two more millisecond-duration radio bursts from SGR 1935+2154, a magnetar located over 14,000 light-years away in the constellation...
Several billion years ago, a short gamma-ray burst unleashed more energy in a half-second than our Sun will produce over its entire 10-billion-year lifetime....
