The Boundary Between Black Holes & Neutron Stars - YouTube - PBS Space Time - astrophysics

Gravitational waves were predicted by Einstein's Theory of General Relativity.On 14 AUG 2024,a signal was received consistent with a gravitational wave traveling at the speed of light at the Hanford LIGO in Washington State,the Livingston LIGO in Louisiana,and the Virgo LIGO in Italy.A neutron star is what's left over after a supernova.About 1.5 Suns of matter is compressed into an area the size of a small city,making the gravity 100 billion times stronger than the gravity of Earth's surface.The signal was consistent with a neutron star being in close proximity to a black hole.*Presented and written by Dr.Matt O'Dowd,an Australian astrophysicist.

Tour: Supernova 1987A Pulsar Wind Nebula - YouTube - astrophysics/cosmology

NuStar,the Nuclear Spectroscopic Telescope Array is a space observatory operated by NASA/Jet Propulsion Laboratory-California Institute of Technology.Its mission is to study the universe in high energy X-rays to better understand the dynamics of black holes,exploding stars and extreme active galaxies.Together with the NASA Chandra X-ray Observatory and the Atacama Large Millimeter/submillimeter Array,a network of 60 radio telescopes in Chile,it has been studying SN 1987A,one of the most studied objects in recent times.SN 1987A is only about 170,000 light years from Earth,so is right next door.Within SN 1987A,a neutron star,the densest object in the universe,has been ascertained that is also a pulsar,the twin bursts of energy coming out of each end being detected as pulses.*Cosmology is the study of the origin,evolution and structures of the universe.*space observatories
