Black holes many times larger than imagined

 

The time has come for astronauts to change the scope of their expectations about black holes. According to the New York Times, a team of international researchers has come to the conclusion that the size of one of the first black hole inventions, Seasonus X-1, is actually much larger than it is thought.

The binary system-based black hole was previously thought to have only 15 solar masses, but is now believed to be 21 solar masses.

While this may not seem very important compared to the supermassive black holes of millions or even billions of solar masses, it is time to change our perception of black holes.

The research team also found that the size of a black hole measured by X-rays was much larger than that found by the laser interferometer Gravitational-Web Observatory (LIGO).

The vehicle has all the technical equipment needed to take pictures of the surface of Mars, analyze the nature of the soil, and send those pictures and information. The vehicle has been sent in a 'capsule' with the spacecraft to avoid any damage during the high-speed collision on the ground. After reaching the atmosphere of Mars. In the last 7 minutes, the vehicle-along with the capsule will crash and slowly stop at one place. This is the scariest and most complicated time.
