On the same day that the MoD release documents on UFO sightings, and yesterday the Vatican said aliens might actually exist.

Ooooh exciting! Bet it's a lump of ice or something stupid.

maybe its a planet that we can move to after we've ****ed up our own.

The UK's Ministry of Defence.

Ministry of Defence (previously called the War Office, which is more appropriate!)

JFK's assasin. He was really an alien.

[Brian Ellis]

Wasn't it JFK who was the alien?

[Fat Tone]

Black Hole?

[High_Jumbllama]

I thought those were already found or at least inferred?

[dZeus]

a 100 y.o. supernova from our galaxy it is

[Lizzard[MPE]]

but why have they "been looking for that for 50years"

[Marshmallowman]

It seems there should be (very) approximately 3 supernovas in our galaxy per century.

We can see some supernova explosions with optical telescopes across half of the Universe, but when they're in this murk we can miss them in our own cosmic backyard," said Stephen Reynolds of North Carolina State University, who led the Chandra study. "Fortunately, the expanding gas cloud from the explosion shines brightly in radio waves and X-rays for thousands of years. X-ray and radio telescopes can see through all that obscuration and show us what we've been missing."

Astronomers regularly observe supernovas in other galaxies like ours, and based on those rates, estimate that about three should explode every century in our Milky Way, although these estimates have large margins of error.
