This is a good part of our farewell to Epic Space Cloud 2020


Sometimes, the universe provides just the right way to express our feelings.

A space cloud 7,500 light years away has given us the most appropriate farewell we can think of for this entire dumpster fire of one year, 2020.

This small group of material is part of a much larger cloud complex called the Carina Nebula, and would not be given a nickname of its own under normal circumstances. But its distinctive shape has given scientists the nickname Defiant Finger.

And that is exactly what it looks like – “Go talk to yourself amazing”, and “Go away, but in very rude words”.

Actually, Defiant Finger which is known as Bok Globule. These are small, dark, dense lumps of dust and gas that are often the birthplace of stars. As condensed areas of clouds, they can fall down under their gravity, and start moving in a star.

The defiant finger, which has 6 solar masses of material, can form stars within it; Because it is so dense, it is difficult to see inside. It appears that the glow is from external sources – the light of the stars shining nearby.

Because young stars are usually bright and warm, they explode their surroundings with radiation. The exterior of the defiant finger globule is being lit and ionized by the Wolf-Rayet star WR25, a very short-lived, giant star at the end of its lifetime; Tr16-244, a hot young supergiant; Or a combination of both.

But when they illuminate, these stars also perish: slowly but surely, they are evaporating the defiant finger. At the current estimated rate of mass loss, the dust cloud has an estimated lifespan of 200,000 to 1 million years.

It is not very long in cosmic terms, not very long. But it is long enough to make a poetic statement: a scream in the void, a distorted gesture in the face of inevitability. And a really suitable way to close the door on 2020.

Thanks, Space. And bring 2021.
