韦布望远镜拍到的小红点：是黑洞，还是黑洞星？

There are many very small red dots in the sky.

People used telescopes to see these red dots.

The telescope is in the sky and can see very far places.

In 2022, it started sending photos to Earth.

The photos have these red dots on them.

Until now, people have found several hundred.

These red dots are very small.

They are very far from us.

The light we see was emitted many years ago.

13.4 billion years ago, these red dots were born.

At that time, stars and everything together were only 500 million years old.

At first, people thought it was many stars crowded together.

Later, people felt that was not right.

In 2023, Kocevski carefully looked at this light.

There is a special pattern in the light.

This light told him that there is a very heavy thing there.

This thing is very small, but very heavy.

Even light cannot escape.

This kind of thing is called a black hole.

He said: The red dots are black holes.

The black hole is eating the gas around it.

The gas is very thick and wraps around the black hole, so the light is red.

But this kind of black hole emits very strong light.

We cannot see this kind of light.

The red dots have almost none of this light.

Another person who studies stars is named Naidu. He said: That's not how it is.

He said: The black hole is inside a very thick gas.

The outside of the gas is very hot and is red.

It looks like a star.

So people call it a black-hole star.

In May of this year, someone measured the weight of a red dot for the first time.

Such a small dot is as heavy as tens of millions of suns.

Some people also say this measurement method is wrong; only one was measured, which is too few.

He said: I have never seen anything like this.
