The Martian Movie And Our Real Journey To Mars

How you look at color is about to get all messed up…

A while back, I asked you to describe what color the moon appears to your eye. I got some pretty varied and entertaining answers, but you overwhelmingly agreed: The moon is essentially white or bright silver.

Well, you’re wrong.

The moon’s not white at all. It’s actually closer in color to an asphalt road, as we can clearly see in this 100% actually real series of images taken of the moon transiting Earth, courtesy of NOAA’s DSCOVR satellite: 

That whole “the moon is white” thing? It’s just a nasty trick played on your brain by … well, another part of your brain. It has to do with the fact that our eyes perceive illumination in a scene relatively, not absolutely. It’s also why this GIF breaks your brain a little:

Bonus: The PBS Digital Studios Science Squad™ brings you a double whammy of perceptual illusions this week! White isn’t the only light that messes with your visual system, not by a long shot. Did you know that red + green can look like… yellow?

Check out the video below from The Physics Girl and let Dianna teach you why, when it comes to colors, you should never quite believe your eyes:

Very true.

Researcher illegally shares millions of science papers free online to spread knowledge

Welcome to the Pirate Bay of science.

A researcher in Russia has made more than 48 million journal articles - almost every single peer-reviewed paper every published - freely available online. And she’s now refusing to shut the site down, despite a court injunction and a lawsuit from Elsevier, one of the world’s biggest publishers.

For those of you who aren’t already using it, the site in question is Sci-Hub, and it’s sort of like a Pirate Bay of the science world. It was established in 2011 by neuroscientist Alexandra Elbakyan, who was frustrated that she couldn’t afford to access the articles needed for her research, and it’s since gone viral, with hundreds of thousands of papers being downloaded daily. But at the end of last year, the site was ordered to be taken down by a New York district court - a ruling that Elbakyan has decided to fight, triggering a debate over who really owns science.

“Payment of $32 is just insane when you need to skim or read tens or hundreds of these papers to do research. I obtained these papers by pirating them,”Elbakyan told Torrent Freak last year. “Everyone should have access to knowledge regardless of their income or affiliation. And that’s absolutely legal.”

If it sounds like a modern day Robin Hood struggle, that’s because it kinda is. But in this story, it’s not just the poor who don’t have access to scientific papers - journal subscriptions have become so expensive that leading universities such as Harvard and Cornell have admitted they can no longer afford them. Researchers have also taken a stand - with 15,000 scientists vowing to boycott publisher Elsevier in part for its excessive paywall fees.

Hubble’s Jupiter Maps Reveals Weird Structures

Over a 10 hour period, the Hubble Space Telescope gazed at the solar system’s largest planet to produce one of the most spectacular maps of Jupiter’s complex and dynamic atmosphere. Immediately astronomers were able to measure the size of the planet’s shrinking Great Red Spot and notice some mysterious structures along the way.

As the spot has shrunk, it’s color has also become more anemic, losing some of its redness. Also, as these new Hubble observations show, a strange wispy structure has formed inside the storm, becoming warped by the high-speed winds that have been clocked at a speed of 540 kilometers (335 miles) per hour. Astronomers, so far, have little explanation as to what this feature is or what caused it.

Another oddity has been spied just north of the planet’s equator — a wave-like structure has formed, something that hasn’t been seen since the Voyager 2 flyby in 1979. During that flyby, these waves were assumed to be a transient event and the fact the spacecraft imaged them was a fluke. But they’ve now returned, no doubt sparking some huge interest as to their origins.

Via his very first tweet, Jeff Bezos announced that his spaceflight company has accomplished a historic first. It sent a rocket to the edge of space and then landed that rocket’s main fuselage gently on dry land.

Most things humans have sent into space are pushed up there by a disposable rocket. Once the rockets do their job, they fall back to earth, usually worse for wear. They have to be rebuilt each time (though sometimes their parts can be reused). That’s an expensive process, especially if you are a private company hoping to bring tourists to space. Virgin Atlantic, Elon Musk’s company SpaceX and Bezos’ Blue Origin all want to do just that. 

And now Blue Origin has paved the way, landing its rocket on its second attempt (the propulsion module was destroyed when they first tried). Here’s the video in full:

Elon Musk responded to the news on Twitter. He pointed out that it requires much greater speed to actually reach orbit than it does to reach the edge of space. (Phil Plait has some good analysis of the exchange over on his Bad Astronomy blog.)

Still, it’s a pretty amazing accomplishment.
