It's a still image that is more about time than space – this picture has not been manipulated or Photoshopped: it's simply a different way of looking at the world

On Halloween 2012, when people were assembling their costumes and candy, the Mars Curiosity rover was assembling something truly spectacular: a jaw-dropping high-definition self-portrait that has to be seen to be believed:

[Click to enjohnny5enate. And yes, oh my yes, you want to.]

This incredible picture is a mosaic made up of 55 hi-res images taken by the MAHLI, the Mars Hand Lens Imager. That’s a camera designed to be able to take close-up shots of nearby rocks and other feature, but can also focus all the way out to infinity, allowing it to take pictures of distant geographical features as well.

Or, in this case, itself! Now get this: MAHLI is located at the end of the two-meter robotic arm. That was extended and then aimed back at the rover so it could take the pictures (think of every Facebook pic you’ve seen of party revelers holding a camera up and taking a snapshot of themselves). So why don’t you see the arm in these shots? It’s because it was edited out! The camera took several pictures which overlapped. So you’d get two shots of, say, the main body of the rover, each with the ...

The Atlantic has rounded up 49 large photos from various sources that illustrate the devastation left by hurricane Sandy in New York and New Jersey. Four days later, millions of people are still without power and thousands cannot return to their homes. Many of them never will, like those who lived in homes destroyed by fire in Breezy Point, Queens, shown here. Link -via Boing Boing

The Black Hole in the Milky Way
At the center of our Milky Way Galaxy, a mere 27,000 light-years away, lies a black hole with 4 million times the mass of the Sun. Fondly known as Sagittarius A* (pronounced A-star), the Milky Way's black hole is fortunately mild-mannered compared to the central black holes in distant active galaxies, much more calmly consuming material around it. From time to time it does flare-up, though. A recent outburst lasting several hours is captured in this series of premier X-ray images from the orbiting Nuclear Spectroscopic Telescope Array (NuSTAR). Launched last June 13, NuSTAR is the first to provide focused views of the area surrounding Sgr A* at X-ray energies higher than those accessible to Chandra and XMM observatories. Spanning two days of NuSTAR observations, the recent flare sequence is illustrated in the panels at the far right. X-rays are generated in material heated to over 100 million degrees Celsius, accelerated to nearly the speed of light as it falls into the Miky Way's central black hole. The main inset X-ray image spans about 100 light-years. In it, the bright white region represents the hottest material closest to the black hole, while the pinkish cloud likely belongs to a nearby supernova remnant.

In a world of a million water pictures, it's easy to dismiss this as "just another reflection shot." Still, this unedited image proves how unreal water can behave under certain circumstances.

Here I stand at the narrowest point of a small lake, and as usual I have thrown objects into the water to see how it behaves visually. Because the lake was so narrow, only a few meters, the circles started to recoil from land. The effect is called, to my knowledge, interference, but I have yet to see anything similar, even after all these years of throwing rocks into the water.

Hubbert's Prescription for Survival, A Steady State Economy :

perscientiamlibertas:

by Robert L. Hickerson

The late Dr. M. King Hubbert, a geophysicist, is well known as a world authority on the estimation of energy resources and on the prediction of their patterns of discovery and depletion.

1. He was probably the best known geophysicist in the world to the general public because of his startling prediction, first made publicly in 1949, that the fossil fuel era would be of very short duration.
2. His prediction in 1956 that U.S. oil production would peak in about 1970 and decline thereafter was scoffed at then but his analysis has since proved to be remarkably accurate.

Less well known were Hubbert’s studies since 1926 on the rate of industrial growth and of mineral and energy resources and their significance in the evolution of the world’s present technological civilization. Clark in “Geophysics” in February 1983 states “”In recent years, he (Hubbert) has assaulted a target — which he labels the culture of money —that is gigantic even by Hubbert standards. His thesis is that society is seriously handicapped because its two most important intellectual underpinnings, the science of matter-energy and the historic system of finance, are incompatible. A reasonable co-existence is possible when both are growing at approximately the same rate. That, Hubbert says, has been happening since the start of the industrial revolution but it is soon going to end because the amount the matter-energy system can grow is limited while money’s growth is not.

“I was in New York in the 30’s. I had a box seat at the depression,” Hubbert says. “I can assure you it was a very educational experience. We shut the country down because of monetary reasons. We had manpower and abundant raw materials. Yet we shut the country down. We’re doing the same kind of thing now but with a different material outlook. We are not in the position we were in 1929-30 with regard to the future. Then the physical system was ready to roll. This time it’s not. We are in a crisis in the evolution of human society. It’s unique to both human and geologic history. It has never happened before and it can’t possibly happen again. You can only use oil once. You can only use metals once. Soon all the oil is going to be burned and all the metals mined and scattered.” That is obviously a scenario of catastrophe, a possibility Hubbert concedes. But it is not one he forecast. The man known to many as a pessimist is, in this case, quite hopeful. In fact, he could be the ultimate utopian. We have, he says, the necessary technology. All we have to do is completely overhaul our culture and find an alternative to money.

“We are not starting from zero,” he emphasizes. “We have an enormous amount of existing technical knowledge. It’s just a matter of putting it all together. We still have great flexibility but our maneuverability will diminish with time.”

All the light that has been produced by every star that has ever existed is still out there, but “seeing” it and measuring it precisely is extremely difficult. Now, astronomers using data from NASA’s Fermi Gamma-ray Space Telescope were able to look at distant blazars to help measure the background light from all the stars that are shining now and ever were. This enabled the most accurate measurement of starlight throughout the universe, which in turn helps establish limits on the total number of stars that have ever shone.

“The optical and ultraviolet light from stars continues to travel throughout the universe even after the stars cease to shine, and this creates a fossil radiation field we can explore using gamma rays from distant sources,” said lead scientist Marco Ajello from the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University in California and the Space Sciences Laboratory at the University of California at Berkeley.

NEW YORK (AP) -- Subways started running again in much of New York City on Thursday for the first time since Superstorm Sandy, but traffic at bridges backed up for miles, long lines formed at gas stations, and crowds of hundreds of people, some with short tempers, waited for buses.

Three days after Sandy slammed the mid-Atlantic and the Northeast, New York and New Jersey struggled to get back on their feet, the U.S. death toll stood at more than 70, and more than 4.6 million homes and businesses were still without power.

Nearly 20,000 people remained stranded in their homes by floodwaters in Hoboken, N.J., across the river from the New York, and swaths of the New Jersey coastline lay in ruins, with countless homes, piers and boardwalks wrecked.

Downtown Manhattan, which includes the financial district, Sept. 11 memorial and other tourist sites, was still mostly an urban landscape of shuttered bodegas and boarded-up restaurants. People roamed in search of food, power and a hot shower.

These types of fake imagery appear every time there is a flood, a storm, or any other type of natural disaster. It’s almost as bad as the fake celeb deaths on Twitter!

The most popular one so far is the Statue of Liberty, shown with an epic storm looming in the background. (pictured below) There is also the shot of the soldiers at attention, and many others.

Human Beings, your prayers have been answered at last. No, not the one where NBC travels back in time to un-fire Dan Harmon. The one where Community finally sets a firm return date.

Meanwhile, Netflix still hasn’t gotten around to setting an exact date for the long-awaited return of Arrested Development, but one site’s got some inside info that narrows down the window a bit. Early 2013 is going to be a great time for comedy nerds. Hit the jump to read more.

Community star Yvette Nicole Brown announced via Twitter today that the brilliant-and-not-yet-cancelled sitcom would return to NBC for its fourth season Thursday, February 7 at 8:00 PM.

Guys, #Community officially has an airdate: Thursday, February 7th at 8pm!

— yvette nicole brown (@yvettenbrown) October 30, 2012

That puts Community‘s actual Season 4 premiere almost four months after the originally announced October 19 date — a fact that the actress cheekily jabbed at in a follow-up tweet.

February 7th is #October19th! Who knew?! :)

— yvette nicole brown (@yvettenbrown) October 30, 2012

Well, better late than never, right? Think of it this way — now you have four extra months to convince all your other friends to tune in and make sure it never gets cancelled.

Besides, that’s still a much shorter wait than the one for Arrested Development‘s fourth season. The Season 3 finale of that cult comedy aired in early 2006, so fans have been waiting almost five years at this point. While Netflix has yet to announce a definite premiere date for Season 4, The Film Stage has received word that the episodes will hit all at once (as previously revealed) sometime in early April. Previously, we knew only that the show would return sometime in spring 2013.

There’s still no word on how many episodes the fourth season will have. Initially, the streaming service had planned for a ten-episode fourth season, but lately has been more vague with the number, saying only that “at least” ten new episodes would arrive in the spring. Maybe they need extra episodes to fit in all those guest stars they keep signing.

Hydraulic jumps occur when a fast-moving fluid enters a region of slow-moving fluid and transfers its kinetic energy into potential energy by increasing its elevation.  For a steady falling jet, this usually causes the formation of a circular hydraulic jump—that distinctive ring you see in the bottom of your kitchen sink. But circles aren’t the only shape a hydraulic jump can take, particularly in more viscous fluids than water. In these fluids, surface tension instabilities can break the symmetry of the hydraulic jump, leading to an array of polygonal and clover-like shapes. (Photo credits: J. W. M. Bush et al.)
