The star that could sterilize a thousand light-years ️

[00:00:00]This is the most dangerous [music] star in our galaxy and it is already dying.

[00:00:05]If a star this big exploded today, we would not [music] see the flash for 7,500 years.

[00:00:11]This is Eta Carinae.

[00:00:13]>> [music] >> A hypergiant, a star so massive, so unstable that [music] it is actively shedding itself into space.

[00:00:21]From our telescopes, it shines 5 million times brighter than the sun.

[00:00:25]And it is dying.

[00:00:27]Eta Carinae sits 7,500 light years from Earth in the constellation [music] Carina, leaking gas, leaking light, leaking time.

[00:00:36]Now imagine you are there.

[00:00:38]Just nearby.

[00:00:40]The radiation alone would sterilize you down to your DNA.

[00:00:45]Your spacecraft's metal hull would glow and peel before the cockpit [music] lights could finish dimming.

[00:00:50]And when Eta Carinae does explode, and it will, the gamma-ray burst could sweep across a thousand light-years, scrubbing planets clean of life.

[00:01:00]And this is only number five.

[00:01:03]The full ranking [music] is on our channel.
