I've been posting a lot about Mars lately - and stay tuned, there's plenty more! - but let's not forget the first planet we ever viewed from space: our own. Here's another lovely time lapse video of Earth made from images taken by astronauts aboard the International Space Station, called Earth Illuminated.
Regular readers might recognize some of the clips used here; for example the opening shot shows the solstice Sun not quite setting over the limb of the Earth. Many of the other features you can see in this video I've explained before too, like air glow, aurorae, and cities from space. Still, it's nice to see them again, some literally in a different light.
