Black Hole Models Par Kyun Sawal Uthate Hain Kareeb Mile, Black Hole Aur Tara | Time Traveller Star

This video is about two major astronomy updates. The closest black hole is in our cosmic backyard and One supernova at 3 different times in cosmic history.

Gaia BH1 is a binary system consisting of a G-type main-sequence star and a likely stellar-mass black hole, located about 1,560 light-years (478 pc) away from the Solar System in the constellation of Ophiuchus. As of 2022, it is the nearest available system that astronomers are reasonably confident contains a black hole, followed by A0620-00.

The star and black hole orbit each other with a period of 185.59 days and an eccentricity of 0.45. The star is similar to the Sun, with about 0.93 M☉ and 0.99 R☉, and a temperature of about 5,850 K (5,580 °C; 10,070 °F), while the black hole has a mass of about 9.62 M☉. Given this mass, the black hole's Schwarzschild radius should be about 28 km (17 mi).

the Hubble Space Telescope has captured a single image of a supernova – or exploding star – at three different points in the explosion. How can that be?

The supernova is so far away that its light left it some 11 billion years ago. We can see it only because an enormous galaxy cluster lies between us and it. The galaxy cluster’s powerful gravity acts as a gravitational lens in space. we’re seeing some light from the supernova from farther back in time … and some from closer in time.
