Magnetic Portals Connect Sun and Earth. "Like giant, cosmic chutes between the Earth and sun, magnetic portals open up every eight minutes or so to connect our planet with its host star. Once the portals open, loads of high-energy particles can travel the 93 million miles (150 million km) through the conduit during its brief opening, space scientists say." [Via]

From grainy stills to gorgeous high-resolution portraits, from intimate pairings to stark contrasts, and from old standbys to little-known surprises, The Planetary Society's Earth galleries offer a rich collection of stunning photography and video footage of our world as seen from both planetary spacecraft and geostationary satellites. It is a vista that has inspired many a deep thought in the lucky few that have seen it firsthand [previously]. Oh, and the rest of the Solar System is pretty neat, too.

30 Incredible Abstract Satellite Images of Earth "From 400 miles away, the earth transforms into abstract art. The global landscape is impressionist, cubist and pointillist." Nice NASA images from 2000, downloadable as wallpaper.

The most widely-distributed photograph in history may be The Blue Marble, a shot taken in 1972 by an unknown crewmember on Apollo 17. In 2002, NASA released a new Blue Marble photograph, familiar to desktops everywhere, using a composite of many photographs. In 2005, Blue Marble: The Next Generation offered even better views and some spectacular animations of the seasons from space. In the same spirit, the Discovery Channel just launched Earth Live, which lets you see the dynamics of weather and climate through a well done interface.

Who Speaks for Earth? "After decades of searching, scientists have found no trace of extraterrestrial intelligence. Now, some of them hope to make contact by broadcasting messages to the stars. Are we prepared for an answer?"

A Pale Blue Dot - An Unauthorized view. Some time before he died in 1996, Carl Sagan recorded a partial audio version of his 1994 book "Pale Blue Dot". Often described as the "sequel" to Cosmos, the audio version of Pale Blue Dot is, at this moment, regrettably out of print. This video is "episode one" of an unauthorized attempt at producing a series of videos based on Carl Sagan's "Pale Blue Dot" audio book combined with a soundtrack and appropriate video and still images intended to recall the feel of the classic documentary series "Ascent of Man" and "Cosmos"

Knowing that Sputnick went up in 1957, when would you guess the first photo from space was taken? If your answer is "more than 10 years earlier", you'd be right. (Previously 1 and 2)

Voyager's Golden Record This is life on earth 1977 as it will appear when Voyager 1 meets life (ETA 40.000 years from now)... and finds a turntable. Pioneers 10 and 11, which preceded Voyager, both carried small metal plaques identifying their time and place of origin for the benefit of any other spacefarers that might find them in the distant future. With this example before them, NASA placed a more ambitious message aboard Voyager 1 and 2-a kind of time capsule, intended to communicate a story of our world to extraterrestrials. The Voyager message is carried by a phonograph record-a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth. Hello, ET!

Project Nova: on the 9th of September three Cambridge engineering students launched a balloon equipped with a camera and tracking devices. It reached a height of 32km and took 857 photographs during its three hour flight, some showing the curvature of the earth. You can also download a KML file to follow the balloon's flight path in Google Earth.

The Gateway to Astronaut Photography of Earth. Over half a million photographs of Earth taken from orbit by astronauts, from 1961 through the present. The ability of the astronauts to rapidly identify interesting phenomena allows them to capture events as they occur, like volcanic eruptions, floods, and hurricanes, or take advantage of the angle of the sun to highlight specific features, like the pyramids or Mount Everest.

NASA thinks we can find another Earth in another nearby star. When we do, how can we possibly travel light-years to get there? It might not be as hard as you'd think . . .

Reflections on a Mote of Dust "We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam." Carl Sagan "Pale Blue Dot"

Discovery-Alpha dodge astronaut's space junk. Do we as a people know how to pollute, or what? A 1999 study estimated there are some 4 million pounds of space junk in low-Earth orbit. I just watched a program on The Learning Channel that also showed how the Cosmonaunts on Mir would simply jettison their waste into space...traveling 18,000 MPH!!! And I thought flipping a cigarette butt out the car window was bad....

Hey, Baby -- did you feel that? The sun, someday, will envelope the Earth and all life as we know it will die. Can we prevent this? Some wacky scientists think that the best thing to do would be to up and move the whole damn planet.
