Mars’ Atmosphere Stripped by Solar Winds, NASA Says This video is not currently supported on your browser. Advertisement Continue reading the main story Video The air on Mars — what there is of it — is leaking away, about half a pound a second sputtering into space, scientists announced on Thursday. The planet’s early atmosphere is thought to have been as thick as or thicker than Earth’s today, and even over the 4.5-billion-year history of the solar system, that slow leak would not explain how it atrophied to its current wisps. Hubble data predicts Milky Way galactic collision When Galaxies Collide! It sounds like an early science fiction novel. However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31). The collision will start in about four billion years, and over the following three billion years the two spiral galaxies will coalesce into a large elliptical galaxy. Based on this data, NASA has produced a video of the upcoming collision. View all
The Facts and Figures about the Power of Visual Content - Infographic We all know that images are compelling. The growth of visual content has been on a rapid upward trajectory over the last 12 months. Social media platforms such as Pinterest and Instagram have taken the social media world by storm. Instagram announced in July that it had acquired 80 million users. To put some further perspective on its adoption and growth, the visual social media network is now being used by 40% of the worlds top 100 brands. Snowflakes Up Close: A Small, Fragile World If you’re one of those people who likes to ponder things while looking out a frosty window on a cold winter day, these pictures will clear up one of those long standing wonders: each snowflake really IS unique. Some look like roman columns, others circuit boards or spaceships. Taken under high magnification using a microscope, these images bring a fragile and beautiful world into view.

Astronomers watch black hole burp after eating a star Scientists have for the first time witnessed a black hole swallow a star and then quickly eject a flare of stellar debris moving at nearly light speed. Astrophysicists tracked the star—about the size of our sun—as it shifted from its customary path, slipped into the gravitational pull of a supermassive black hole, and was sucked in, says Sjoert van Velzen, a Hubble fellow at Johns Hopkins University. “These events are extremely rare,” says van Velzen, lead author of the study published in the journal Science. “It’s the first time we see everything from the stellar destruction followed by the launch of a conical outflow, also called a jet, and we watched it unfold over several months.”
Total Solar Eclipse 2012 photos, near Mount Carbine, Queensland, Australia November 14, Queensland, Australia Homepage Astrophotos Australia 2012 photos Purchase Photos! Total Solar Eclipse of November 14, 2012, as seen from a hilltop about 20 miles west of the Outback town of Mount Carbine, Queensland, along the Mulligan Highway (Peninsula Development Road), a road only paved in recent years. Heading inland to get away from coastal showers and clouds which were promising to interfere with the viewing, we drove some 150 miles into the outback to find a good spot the day before and settled upon a remote hillside, up along a dirt track that pulled away from the main road. The location was about 40 miles inland, and 67 miles from Cairns, as the crow flies. About 20 other cars camped out here as well under very dark skies.
How Star Wars Changed the World Hopefully reading this infographic will give you a nice break, writing about it has for me. I sit here amidst a slew of homework, from writing a paper on Rousseau and his Discourses to studying Chinese Politics. Now after finding this infographic, all I want to do is put everything away and watch Star Wars. Whether you are a fan of the double triology (? Sixology? Whatever you want to call it) or not, there is no doubt the series has permeated our society.

Unfortunately, you’ve missed your chance long ago as the supercontinent of Pangea no longer exists. But thanks to the illustrative talents of Massimo Pietrobon, you can see how Pangea may have looked before the epic landmass started ripping itself apart 200 million years ago to form the continents and countries of the world today. Image Credit: Massimo Pietrobon Surrounded by a superocean called Panthalassa, the bulk of Pangea was in the southern hemisphere, unlike how the continents are spread out now. Evidence for Pangea has been found in similar fossils recently discovered in South Africa, India and Australia, such as the therapsid Lystrosaurus and similar rock forms seen between the eastern coast of South America and the western coast of Africa.
Hubble zooms in on a space oddity A strange, glowing green cloud of gas that has mystified astronomers since its discovery in 2007 has been studied by Hubble. The cloud of gas is lit up by the bright light of a nearby quasar, and shows signs of ongoing star formation. One of the strangest space objects ever seen is being scrutinised by the penetrating vision of the NASA/ESA Hubble Space Telescope. A mysterious, glowing green blob of gas is floating in space near a spiral galaxy.
