Black hole-Causes,size etc..

What is a black hole?

A black hole is a region of space where gravity is so strong that even light cannot escape. Because stuff has been compressed into a small space, gravity is extremely powerful. This can occur when a star dies.

People cannot perceive black holes because no light can escape. They are undetectable. Space telescopes equipped with specialised equipment can aid in the discovery of black holes. Special technologies can observe how stars in close proximity to black holes behave differently from other stars.


What Size Are Black Holes?

Black holes can be large or small in size. Scientists believe that the smallest black holes are as small as one atom. These black holes are extremely small in size but have the mass of a massive mountain.

What Causes Black Holes?

According to scientists, the smallest black holes created when the cosmos first began.

Stellar black holes form when the core of a massive star collapses in on itself. When this happens, a supernova occurs. A supernova is an exploding star that sends a portion of its mass into space.

Scientists believe that supermassive black holes formed at the same time as the galaxy in which they exist.

If Black Holes Are "Black," How Do Scientists Know They Exist?

A black hole cannot be seen because immense gravity draws all light into the black hole's centre. However, astronomers can observe how the black hole's enormous gravity affects the stars and gas surrounding it. Scientists can study stars to see if they are circling or travelling around a black hole.

When a black hole and a star collide, high-energy light is produced. Human eyes cannot see this type of light. To observe the high-energy light, scientists employ satellites and telescopes in orbit.

Can a Black Hole Destroy the Earth?

Black holes do not roam the universe devouring stars, moons, and planets. Earth will not fall into a black hole since there are no black holes close enough to the solar system for this to happen.

Even if a black hole with the same mass as the sun replaced the sun, Earth would not fall into it. The gravity of the black hole would be the same as that of the sun. The Earth and the other planets would orbit the black hole in the same way that they currently orbit the sun.

The sun will never become a black hole. The sun is not a powerful enough star to become a black hole.

10 facts about sun

Hello friends.. In this post we will saw some facts about our Sun First we must know.. What exactly is tha sun..?  Our sun is a spherical ball of helium and hydrogen atoms; it is the star of our planet and others. In other words, a star is a large mass within which nuclear fusion and fission must occur. Because the Sun possesses all of these characteristics, we refer to it as the Nakshatra. In this universe, there are countless stars like our sun. The sun spins around its own axis This Sun revolves around the Earthfrom west to east. It could take between 225 and 300 million years to complete its orbit around the Milky Way. The diameter of the sun This sun is so massive that about 1,30,000 Earths like ours can fit inside it. The Sun's Age According to researchers, the sun is now 5 billion years old. This is a star's middle age, and in a few thousand years, the sun will enter its last age as hydrogen begins to burn. The sun's temperature Our Sun is a yellow star with a temper

Lunar eclipse and difference between Solar eclipse and Lunar eclipse?

What is Lunar eclipse? Lunar eclipses occur when the Earth passes between the sun and the moon, producing a shadow on the moon's surface. They can only occur during a full moon and are a favourite event for skywatchers worldwide because they do not require any additional equipment to enjoy (unlike solar eclipses).  Earth will witness two moon eclipses in 2023. On May 5, 2023, a penumbral lunar eclipse was visible across regions of Africa, Asia, and Australia. The second and last lunar eclipse of 2023 will be a partial lunar eclipse on October 28 that will be visible across areas of the Eastern Americas, Europe, Africa, Asia, and Australia. Check out our lunar eclipses 2023 guide to find out when, where, and how to see this year's lunar eclipses. A lunar eclipse occurs when Earth blocks sunlight from reaching the moon, casting a shadow across its surface. During a lunar eclipse, the sun-blocking Earth creates two shadows on the moon: the umbra, which is a full, dark shadow, and

What is Solar eclipse...and its types?

What is Solar Eclipse? A solar eclipse is a breathtaking sight and a once-in-a-lifetime astronomical phenomenon. Each one is only viewable from a specific location. The Moon completely eclipses the Sun. A solar eclipse occurs when the New Moon passes between the Sun and Earth, blocking the Sun's rays and creating a shadow on sections of the Earth. Because the Moon's shadow is too small to encompass the entire globe, it is always limited to a specific area (see map drawings below). This area fluctuates throughout the eclipse because the Moon and Earth are constantly in motion: the Earth rotates around its axis while orbiting the Sun, while the Moon orbits Earth. This is why solar eclipses appear to move from one location to another. Types There are four types of solar eclipses. The magnitude of the eclipse, or how much of the Sun's disc is eclipsed, is determined by where the Moon's shadow falls on Earth. ●Partial solar eclipses occur when the Moon only partially obscure
