The oldest known material on Earth is a tiny bit of zircon crystal that has remained intact for an incredible 4.4 billion years, a study confirms. The ancient remnant of the early Earth may change the way we think about how our planet first formed. The crystal is the size of a small grain of sand, just barely visible to the human eye. It was discovered on a remote sheep farm in western Australia, which happens to sit on one of the most stable parts of our planet. "The Earth's tectonic processes are constantly destroying rocks," said John Valley, a professor of geoscience at the University of Wisconsin-Madison, who discovered and dated the crystal.

The Voyager 1 spacecraft is the first human-made object to venture into interstellar space. Even if defined only by distance, the NASA/Jet Propulsion Laboratory twin Voyagers are America's greatest space adventure. They've been flying successfully for more than 36 years and are billions of miles from home. What isn't widely known is that they almost never made it out there. The first proposed mission in the late 1960s was for four spacecraft to take advantage of a rare alignment of the four outer planets of the solar system; Jupiter, Saturn, Uranus and Neptune would all be on the same side of the sun. However, in December 1971, NASA decided it couldn't afford the $1-billion price tag for a 12-year "grand tour" mission with four spacecraft.

No one can accuse the people at the CW of not giving its audience what they think it wants. "Star-Crossed," which premieres Monday and might easily be reverse-engineered from its title alone - it's "Romeo and Juliet," with aliens - adds another story of cross-cultural, interspecies romance to the network of "Beauty and the Beast" and "The Vampire Diaries" (and "Hart of Dixie," for that matter). For a certain sort of moony viewer, there is no love so true as the impossible love that is meant to be. Created by Meredith Averill (formerly a story editor at "The Good Wife")

A massive asteroid the length of three football fields will make its closest approach to Earth tonight, and you can watch it fly by live, right here. Beginning at 6 p.m. PST, the astronomy website Slooh.com will provide a live video feed of the asteroid from a telescope in the Canary Islands. The free show will last about an hour and will be visible in the video box above. Asteroid the length of 3 football fields eludes sky-watchers The asteroid is known as 2000 EM26, and although it is big, it poses no threat to Earth.

A storm warning has been issued for space, where a "cannibal" coronal mass ejection grabbed the attention of space-weather watchers. The sun -- at a peak of activity in the 11-year solar cycle -- hurled a pair of CMEs that reached Earth early Saturday morning, Pacific time. The ejections, as NASA's Alex Young says, "are a huge release of solar material, billions of tons, and magnetic field. " Upon reaching Earth, they can wreak havoc with our power grid -- and, on the bright side, create gorgeous auroras.

With the American South locked in a deep freeze, you can be sure that plenty of the folks suffering through the snow and ice storms are interpreting the big chill as more proof that global warming is a hoax. “Warming?” they scoff. “How can the planet be warming when it's so darn cold?” People in other parts of the world seem to have no great difficulty understanding the science but, in the good old USA where quite a few people consider science just another political opinion, it is going to take a lot longer to get most people to accept the cold facts about a warmer world.

BERLIN - They stood an hour or more in four long lines, inching toward the ticket counters with agonizing slowness. This being Germany, they were orderly and polite. And this being the Berlin International Film Festival, they didn't mind the wait. It gave them time to thumb through the program, checking out obscure titles, circling ones that looked promising. A scruffy student searched for movies from the Balkans, while a retired engineer consulted an impressive grid drawn in his notebook of dates and show times, making sure that Lars von Trier's "Nymphomaniac" (which he wanted to see)

Oh gosh, it turns out that old Walt was right: It is a small world after all. Or at least it is to NASA's Curiosity rover, which snapped a picture of Earth and the moon, looming bright but tiny in the night sky, from the surface of Mars recently. In the picture , Earth is so small that NASA helpfully put an arrow pointing to it on the photo it sent out; although scientists say that were a human standing on Mars next to Curiosity, he or she could see Earth with the naked eye . Which is not bad, considering that the planets were 99 million miles apart when the Earth “selfie” was snapped.

How do young, naive salmon with no migratory experience somehow voyage through vast, shifting ocean waters to wind up at specific feeding grounds that are hundreds, even thousands, of kilometers away from the rivers where they were hatched? It turns out these fish may have a magnetic 'map' in their heads that enables them to sense and navigate using the Earth's magnetic fields rather like a GPS. The findings, published in Current Biology, “likely explain the extraordinary navigational abilities evident in many long-distance underwater migrants,” the study authors wrote.
