Is it necessary to have some basic knowledge about Science to read this article? No, don’t need it. Ok, let’s get into the topic.
Dr. Einstein was the first person who predicted these Black Hole along with his paper General Theory of Relativity in 1916. Later the first Black Hole was discovered practically or physically in the year 1971.
What is a black hole?
Our sun-like stars can convert into black holes after they expire. The black hole is the region filled with black-colored space that is having a high gravitational pull with massive density. The conversion from a star to a black hole took millions of years.
Physics laws are not applicable in this region because of the high Gravitational Force. Even the speed of light can’t escape through it. Based upon the size of a Black Hole, they are of three types :
- supermassive black holes
- intermediate black holes
- stellar or small black holes
How we find them?
If an empty space is found surrounded by a region that is not possible to escape then we confirm that it is a Black Hole. Telescopes are optical devices that are used to find distinct objects like stars, satellites, asteroids, black holes, planets, etc.
The telescope is one of the great inventions by Hans Lippershey and later it was developed by Galileo and he was the first person who aims at the sky.
Different Telescopes :
- Kepler Telescope
- Hubble Space Telescope
- James Webb Space Telescope
- Atacama Large Millimeter Array (ALMA)
- Arecibo Observatory
- Compton Gamma Ray Observatory
- Spitzer Space Telescope
- Karl G. Jansky very large array
- W.M. Keck Observatory
- Palomar Observatory
There are many Space Telescopes but mainly these are used and each of these has their unique specialty.
HUBBLE SPACE TELESCOPE :
Dr.Edwin Hubble used the Telescope in the 1920s and it is the large telescope at that time. It is the first major optical telescope to be placed in space.
The Hubble space telescope is named in honor of astronomer Dr. Edwin Hubble. Hubble’s launch and deployment in April 1990. With the help of this Telescope, Dr. Hubble proved that the universe is expanding, and it leads the foundation of the Big Bang Theory. It is about 13.3 meters long, which is approximately the length of a long school bus. Hubble doesn’t travel to stars, galaxies, or any other planets. It whirls around the Earth at a speed of 17,000 mph.
Hubble find the ‘missing link’ by a Black hole in 2020
Hubble space telescope recently discovered an intermediate black hole. With this discovery Hubble clarifies the doubt which was raised in 2006. In 2006 the two famed observatories by NASA caught powerful X-rays in space, but we don’t know where they came from whether they related to our milky way galaxy or from another galaxy.
Hubble clarifies this with high-resolution photography showing the X-ray source is a black hole also known as 3XMM J215022.4-055108 is in a star cluster at the edge of another galaxy.
The black hole is an intermediate-mass type black hole and the X-ray glow from the shredded star allowed astronomers to estimate the black hole mass is 50,000 solar mass. In 2009 Hubble was a tie-up with NASA’s Swift Observatory and ESA’s XMM-Newton to identify what is interpreted as an IMBH, called HLX-1. “The main difference is that our object is tearing a star apart, providing strong evidence that it is a massive black hole, instead of a stellar-mass black hole as people often worry about for previous candidates including HLX-1,” Lin said.
- 14 years’ suspense was revealed with evidence.
- We found a new Intermediate Massive Black Hole. (3XMM J215022.4-055108)
- It helps scientists in further researches.
