It sure feels flat, right? (Life Noggin)
I'm ashamed to admit that I never learned much about the International Space Station. But after seeing the IMAX 3D documentary A Beautiful Planet, I feel like I spent 45 minutes in it, and it was emotional and thrilling. I'm normally not a big fan of 3D movies, but the quality was so high that it didn't bother me and instead made the experience of learning about life inside the ISS that much better.
I was enthralled the entire time I watched the movie. I felt like I was floating in the ISS, observing the astronauts right in front of me as they ate, cut their hair, made espresso, helped each other get into their spacesuits, and played the bagpipes. I remember reading somewhere that one of the requirements of being an astronaut is that you can't be arrogant or have a big ego because those aren't good traits to have when you live in close quarters for months on end with other people. The astronauts on the ISS all seemed very smart, good natured, and kind. I wanted to hug them all.
The movie, which is narrated by Jennifer Lawrence, is called A Beautiful Planet because the main star of the show is our planet as filmed by crew of the ISS. We've all seen images of the Earth from space, but to see them in 3D on giant screen in crystal clarity is another experience altogether. My 13-year-old daughter was shocked by the nighttime footage of South and North Korea. Read the rest
In China, teens and twentysomethings are wearing little plastic accessories on their heads in the shape of tiny little sprouts, fruit, or flowers. Nobody's exactly sure where or how the trend started, but it's... growing.
The origin of this "large face" on the side of a cliff remains unknown. Read the rest
This image shows magnetic anomalies in the South Pacific — underwater lines where the crust of the Earth either matches up with the planet's overall magnetic polarity (reds and purples) or is completely reversed (blues). Invisible to the naked eye, these stripes run along all of Earth's ocean basins. We first noticed them in the 1950s and, at first, they were a giant mystery. Why would there be these distinct lines of magnetism, and why would the lines fluctuate in their polarity? As Chris Rowan explains at the Highly Allochthonous blog, the answer ended up being a key part of proving that chunks of the Earth's crust were moving away from each other.

Fred Vine and Drummond Matthews thought through the consequences of the hypothesis put forward by Harry Hess, that new oceanic crust was being continuously produced by the eruption of basalt at mid-ocean ridges. When combined with the facts that newly cooled basalt has a strong remanent magnetisation aligned with the ambient magnetic field, and that the Earth’s magnetic field reverses its polarity every million years or so. Vine and Matthews* argued that if seafloor spreading was indeed occurring at mid-ocean ridges, then linear positive and negative magnetic anomalies, formed from crust produced in normal and reversed polarity chrons, would form a symmetric pattern around the mid-ocean ridges, which is exactly what we see.
It's not the work of aliens. Instead, you can chalk these crop circles up to humans + money + time. And, with the help of satellite imaging, you can watch as humans use money to change the desert over the course of almost 30 years.
Landsat is a United States satellite program that's been in operation since 1972. Eight different satellites (three of them still up there and functioning) have gathered images from all over the world for decades. This data is used to help scientists studying agriculture, geology, and forestry. It's also been used for surveillance and disaster relief.
Now, at Google, you can look at images taken from eight different sites between 1984 and 2012 and and watch as people change the face of the planet. In one set of images, you can watch agriculture emerge from the deserts of Saudi Arabia — little green polka-dots of irrigation popping up against a vast swath of tan. In another se, you'll see the deforestation of the Amazon. A third, the growth of Las Vegas. It's a fascinating view of how we shape the world around us, in massive ways, over a relatively short period of time. Read the rest
View of the Earth as seen by the Apollo 17 crew traveling toward the moon. This translunar coast photograph extends from the Mediterranean Sea area to the Antarctica south polar ice cap. This is the first time the Apollo trajectory made it possible to photograph the south polar ice cap. Note the heavy cloud cover in the Southern Hemisphere. Almost the entire coastline of Africa is clearly visible. The Arabian Peninsula can be seen at the northeastern edge of Africa. The large island off the coast of Africa is Madagascar. The Asian mainland is on the horizon toward the northeast."Read the rest
John Streeter, who is a television producer with NASA at Johnson Space Center in Houston, sends this cool video and tells Boing Boing:
NASA.gov link, and here's the video on YouTube.
It is all real, all shot from the International Space Station and all beautiful. It is time-lapse photography that showcases stars, cities at night, lightning storms and the aurora all from the vantage point of the space station. Also, there is a link at the end where you can visit, download and create your own videos if you wish.
The station is a remarkable engineering achievement and this is just a small side benefit of being in orbit. I hope you enjoy.

Philip Bump put together this great comparison of Earth's Mt. McKinley and Mars' Mt. Sharp (as photographed by the Curiosity rover).
Officially, it's Aeolis Mons, and it stands 18,000 feet above the crater floor. Here's how that compares to Mount McKinley, America's tallest peak at 20,320 feet. The sea levels / floor levels are roughly comparable. But this is just an approximation. Do not make wagers based on this.
Today is the final day for voting in the USGS "Earth as Art" image project. To celebrate the 40th Anniversary of the Landsat Program on July 23, 2012, the federal agency seeks your help in selecting the 5 coolest images from more than 120 scenes.
For 40 years Landsat satellites have been acquiring images of the land cover of the planet. The satellites have given us spectacular views of mountains, valleys, coastal areas, islands, volcanic fields, forests, and patterns on the landscape. By highlighting some of those features and creatively crafting the colors we have developed a series of "Earth as Art" perspectives that reveal the artistic side of Landsat. The Top 5 "Earth as Art" images will be announced on July 23 in Washington, D.C., at a special event commemorating the launch of the first Landsat satellite.
Vote here, by end of day today.
Image above, from the Landsat collection: Akpatok Island lies in Ungava Bay in northern Quebec, Canada. Accessible only by air, Akpatok Island rises out of the water as sheer cliffs that soar 500 to 800 feet (150 to 243m) above the sea surface. The island is an important sanctuary for cliff-nesting seabirds. Numerous ice floes around the island attract walrus and whales, making Akpatok a traditional hunting ground for native Inuit people.
Scientists have long speculated that large tsunamis could be linked to the calving of icebergs—where chunks of ice break off of the side of a glacier or ice shelf and float away. The Tohoku earthquake and tsunami that happened in March off the coast of Japan finally gave them much more direct evidence of this phenomenon. Fascinating stuff, and a great reminder of how interconnected the world really is.
