Black Hole and Earth : Black holes are mysterious objects that have fascinated scientists and space enthusiasts for decades. Black holes are also terrible, because their gravitational pull is so strong that they do not allow anything to pass through them, not even light. The US space agency NASA (National Aeronautics and Space Administration) is celebrating Black Hole Week from May 2-6 to make people aware of the field of spacetime and its different types.

Chandra Observatory, the flagship-class space telescope launched by NASA in 1999, shares interesting trivia about black holes and how Earth can be turned into a black hole. The observatory said in a post on its official Twitter handle with the hashtag #BlackHoleWeek, “To turn the Earth into a black hole, we have to compress all of its mass into an area the size of a marble. Just thought you might know. want.”

In another tweet, the Chandra observatory said, “As material spins around a supermassive #blackhole, extreme forces can travel at nearly the speed of light in the form of jets to move matter away from the black hole. Image: Cygnus A – Its incredible jets span over 600,000 light years!”

Since light cannot escape from black holes, people cannot see them. Therefore, space telescopes with special equipment are needed to detect black holes.

How big are black holes?
According to NASA, black holes can be both big and small. The smallest black holes can be as small as an atom, while others – called stellar ones – can have a mass 20 times that of the Sun. NASA further said that the largest black hole is called “supermassive”. These black holes have masses that together are more than 1 million suns.

How are black holes formed?
The Encyclopdia Britannica says that the death of a massive star can lead to the formation of a black hole. This suggests that when such a star has exhausted the internal thermonuclear fuel in its core at the end of its life, the core becomes unstable and gravity collapses upon itself.

Can a Black Hole Destroy Earth?
NASA says that Earth is protected from such a phenomenon for two reasons: First, black holes do not move around in space, eating up stars, moons and planets. Second, the Earth will not fall into a black hole because no black hole is close enough to the Solar System.
