There was a lovely total solar eclipse over parts of Africa, Europe, and Asia yesterday. See the photo galleries from Spaceweather, BBC, various Flickr users, and the International Space Station.

Astronomy Picture of the Day is ten years old today, and over its long life has featured great photos of Earth, the Milky Way, the Sun, Stars - and even Water on Mars.
Happy Birthday APOD.

Spectacular atmospheric optics.
Beautiful pictures of atmospheric phenomena, common and rare. You can also run your own halo simulations if you like... (Found in New Scientist's Weblinks, an extensive, annotated collection of all kinds of science links from all over the web.)
