In rare instances, this companion star is also massive enough to create a neutron star ... South Africa, and the Hubble Space Telescope, we can follow its development in great detail." ...

Just a sugar cube of neutron star matter would weigh about one hundred million tons on Earth. A neutron star's almost incomprehensible density causes protons and electrons to combine into neutrons ...

Only black holes have a higher mass density. While black holes colliding with each other can only be detected by the emitted gravitational waves, neutron star mergers briefly emit a flash of light ...

A supernova is a cataclysmic stellar death that leaves behind a black hole or neutron star. It is the biggest ... NASA's Goddard Space Flight Center / ESA / Hubble / L. Calcada illustration ...

Read the paper: Real-time inference for binary neutron star mergers using machine learning Gravitational waves are a prediction of general relativity, Albert Einstein’s 1915 theory of gravity.

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of ...

The Hubble Space Telescope captured an image of a spiral galaxy, NGC 4900, and a nearby star in the constellation Virgo. Despite appearing close, the star is 7,109 light-years away, while the ...

Hubble once again lifts the veil on a famous—and frequently photographed—supernova remnant: the Veil Nebula. The remnant of a star roughly 20 times as massive as the sun that exploded about ...

As it nears 35 consecutive years of space service, the NASA/ESA Hubble Space Telescope has taken ... It is the remnants of a star that was roughly 20 times as big as our sun and exploded about ...

Symbiotic star: NASA's Hubble Space Telescope has captured Mira HM Sge, a symbiotic star located 3,400 light-years away in the constellation Sagitta. The star system consists of a red giant and a ...
