submit lovely photos

Please include a source! Please include a source! Please include a source!
If the picture belongs to you, say so, and provide relevant details, i.e. where the picture was taken.
If the picture does not belong to you, provide a click-through link that links back to more than just a high-res version.
If you do not provide a source, I will message you and ask for one, and if I can’t do that (i.e. because your ask is disabled), I will delete your submission, which makes both of us sad.
Finally, select the “science” tag along with every other applicable tag.
THANKS FOR SUBMITTING!
p.s. If you want to submit a cool webpage/video/somethingelse, send it through my ask! Thanks!
