Must've had a lot of copper in that asteroid.

Probably nickel and/or salts of barium. Copper burns blue as a pyrotechnic colorant.

Ah ok. I was going to say nickel but I did a quick search and somehow I read that it was copper.

Depending on the salt you can make both blue and green. Copper sulphate flame test is a pretty common school lab practical isn't it?

A lot of spaceship debris looks like this because copper is used in a lot of rocket engines.

Alternatively or additionally, I think oxygen plasma glows blue or green, because northern lights (near the poles, at least) are greenish.

One of the coolest photos I've ever seen. I like mountains amid the human development too

I know I'm being pedantic but aren't all pictures of meteors by accident?

[–] Siethron 6 points 6 months ago

Nah, we predict metoer showers all the time.

I don't understand why they call it an "accident". The camera was set up and taking timed pictures. I just don't think "accident" is accurate

Looks like the Skunkworks guys finally figure out how to build a Deathstar laser.

[–] [email protected] 3 points 6 months ago

Clearly Jewish space lasers. This is just a cover-up

Why does the grainy effect make it seem so much more substantial?
