Say hello to your new desktop background.

For the weekend: vintage science art from the backs of books in LIFE Magazine's Science Library, published throughout the 1960s by Time Inc. See also: this set of minimalist science posters by graphic designer Kazumasa Nagai, also featured in the magazine's 60s Science Library.

Feast your eyes on the artistic musings of graphic designer Kazumasa Nagai. Featured below: "The Mind," "Growth," and "The Cell," three posters in a series of science-themed prints featured in LIFE Magazine's Science Library during the 1960s. See more of Nagai's work here.

This isn't just about when a dying star gobbles up its life-supporting planets, as will happen with our own Sun five billion years from now. A star's internal chemistry can doom a planet's life long before the star itself dies.

Biologically speaking, it isn't that hard to create very simple, one-celled organisms. But the leap to multicellular life requires many factors to line up just perfectly. Now a new hypothesis suggests we wouldn't even be here without some well-timed erosion.

There's an increasing body of evidence that suggests organic molecules that formed the origin of life on Earth got their start on meteors — but then how did the organic compounds get there to begin with?

The fossil record reveals the last 3.4 billion years of life on Earth. But before then, when life first emerged, we have next to nothing. The consensus view is that life began in the oceans... but there might be another, weirder, possibility.

This newly discovered planet is just 22 light-years away. Its discoverers are calling it the "new best candidate" to support water, and possibly life. The planet's unique features could even make it the ideal home for creatures like the Predator!

There could be over 150 billion planets in our galaxy alone, which makes the chances of life on other words look very solid indeed. But there's one snag: the universe's most common stars might not support life at all.

Got a bad case of the Mondays? The dulcet tones of Sir David Attenborough are just what you need to get out of your funk and back on your feet. Here's to the week ahead, everybody!
