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?

[–] [email protected] 10 points 5 months ago (1 children)

They're not necessarily accidental (for example, taking long exposures during a meteor shower), but yes the vast majority of meteor pictures are by chance. A few meteors have been detected just before entry and photographed but that number is in the single digits.

Also it's mentioned for emphasis. It may seem obvious but it's worth pointing out.

[–] [email protected] 5 points 5 months ago

Nah, we predict metoer showers all the time.

[–] [email protected] 5 points 5 months ago

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

The chances of anything coming from Mars are a million to one...

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

[–] [email protected] 3 points 5 months ago

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

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

Might want to avoid semi-trucks and AC/DC for a minute.
