Space News: Our planet is scarcely even a speck in this infinite, deep, and enigmatic cosmos. There are billions and trillions of times larger structures in this universe, not just the Earth but even our sun, that is unimaginable. Many things have come to the fore as space scientists around the world have attempted to grasp and understand this cosmos with present technology.
According to space experts, black holes are the most massive and powerful objects in the universe. Its gravitational force is so strong that even light cannot escape its grasp. As a result, it is not visible. A common black hole can be several times larger than our Sun, or it can be so large that it can contain billions of Suns.

Space News: These are universe’s largest black holes
Consider Sagittarius A*, the supersized black hole in our galaxy. This single black hole can accommodate 4.3 million suns like our own. It is approximately 26,000 light-years from Earth.
Likewise, the NGC 7727 galaxy has two supermassive black holes. These two stars are around 1,600 light-years apart. One weighs 6 million solar masses (equal to 6 million suns), while the other weighs more than 150 million solar masses (equivalent to 15 million suns).
Astronomers predict that in the next 250 million years, these two will merge to become a supermassive black hole capable of hosting millions of suns. Let us tell you that such black holes abound throughout the universe.
So far, scientists have discovered several such black holes, each of which is many times larger than the entire solar system.
“Direct Hubble Space Telescope measurements confirm the presence of over 100 supermassive black holes,” said Jeremy Schnittman, a theorist at NASA’s Goddard Space Flight Centre in Greenbelt, Maryland.
NASA created an animation film to demonstrate the size of these black holes. In this film, our Sun and Solar System are compared to various-sized black holes. NASA’s Twitter account also posted the animation movie.
When we say “supermassive black holes,” just how do they measure up?
Using their shadows for size, we’ve rounded up 10 black holes and compared them to objects in our solar system. Don’t worry – these black holes are many light-years away: https://t.co/Vb6zIWzHh6 #BlackHoleWeek pic.twitter.com/pjgzio0Zcj

The black hole depicted at the end of this animation is located at the heart of the M87 galaxy. It weighs 5.4 billion solar masses (the equivalent of 540 million Suns). Even a ray of light travelling at 670 million miles per hour (1 billion kilometres per hour) would take nearly two and a half days to cross the shadow of this black hole.
