LIGO and Virgo team members estimate that the candidate gravitational signal referred to as S190425z originated from the region outlined on the sky map. The signal likely came from two colliding neutron stars. Because only LIGO Livingston and Virgo saw the signal (LIGO Hanford was offline at the time), its localization was not very precise, covering about 18 percent of the sky.

Physicists have detected first-ever collision of black hole and neutron star

The National Science Foundation's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector recently detected the first ever observed merger between a black...

Gravitational waves hint at detection of black hole eating star

Gravitational waves may have just delivered the first sighting of a black hole devouring a neutron star. If confirmed, it would be the first...

Astronomers detected a new signal for a neutron star collision

NASA’s Chandra X-ray Observatory has recently discovered a NASA’s Chandra X-ray Observatory in a galaxy 6.6 billion light years from Earth. This bright burst...
CTB 1, seen here in a deep exposure that highlights visible light from hydrogen gas, is the expanding wreckage of a massive star that exploded some 10,000 years ago. The pulsar formed in the center of the collapsing star is moving so fast it has completely exited the faint shell. Credit: Copyright Scott Rosen, used with permission

NASA’s Fermi satellite clocks Cannonball pulsar speeding through space

A pulsar is a highly magnetized rotating neutron star that emits a beam of electromagnetic radiation. One such pulsar PSR J0002+6216 has a radio-emitting...
MIT physicists have calculated the pressure distribution inside a proton for the first time. They found the proton’s high-pressure core pushes out, while the surrounding region pushes inward.

For the first time, physicists calculate proton’s pressure distribution

Neutron stars are the smallest and densest objects in the Universe, inside which gravitational forces crush protons and electrons together, turning them into particles...
Bright green sources of high-energy X-ray light captured by NASA's NuSTAR mission are overlaid on an optical-light image of the Whirlpool galaxy (in the center of the image) and its companion galaxy, M51b (the bright greenish-white spot above the Whirlpool), taken by the Sloan Digital Sky Survey.Credit: NASA/JPL-Caltech, IPAC

In colliding galaxies, a pipsqueak shines bright

In the nearby Whirlpool galaxy and its companion universe, M51b, two supermassive black holes heat up and devour encompassing material. These two beasts ought...

Birth of a black hole or neutron star captured for first time

Scientists at the Northwestern University have captured the mysteriously bright object that burst in the northern sky this summer. Dubbed AT2018cow or “The Cow,” the object...
The three panels represent moments before, during, and after the faint supernova iPTF14gqr, visible in the middle panel, appeared in the outskirts of a spiral galaxy located 920 million light years away. The massive star that died in the supernova left behind a neutron star in a very tight binary system. These dense stellar remnants will ultimately spiral into each other and merge in a spectacular explosion, giving off gravitational and electromagnetic waves. Credit: SDSS/Caltech/Keck

Astronomers spot a completely new type of supernova explosion

Astronomers at the Caltech have recently observed the peculiar death of a massive star that exploded in a surprisingly faint and rapidly fading supernova. These...
This is an illustration of a pulsar wind nebula produced by the interaction of the outflow particles from the neutron star with gaseous material in the interstellar medium that the neutron star is plowing through. Such an infrared-only pulsar wind nebula is unusual because it implies a rather low energy of the particles accelerated by the pulsar’s intense magnetic field. This hypothesized model would explain the unusual infrared signature of the neutron star as detected by NASA’s Hubble Space Telescope. Credits: NASA, ESA, and N.
