Finally, some high-quality photos from Chang’e 3! | The Planetary Society

Once again, tips from helpful users at nasaspaceflight.com and from Twitter have led me to a new pile of photos from the Chang’e 3 mission. And these are the best-quality ones I’ve seen yet. Almost all of the images I’ve seen to date have been shared through a bizarre roundabout method of projecting them on a screen, then filming them with a video camera, then aired on television, and then screen-grabbed. These photos are different: they are clearly direct from the original digital data. They’re still not perfect — they have been downsampled, contrast-enhanced, watermarked, and JPEG-compressed — but they’re so, so much better than what I’ve seen before, rich with detail and nuanced in color. They were also accompanied by a little bit of information about when they were taken, which is great. Here’s the trove of images.

Flyover Video of Ceres Shows the Grandeur of Space Exploration – Universe Today

This new flyover video of Ceres was created using enhanced images taken by the Dawn spacecraft’s framing camera. It was produced by the camera team at the German Aerospace Center, DLR, using images from Dawn’s high-altitude mapping orbit of 900 miles (1,450 kilometers) above Ceres’ surface. The video shows a stark and stunning world.

Residents of Iqaluit, Nunavut woke up on Tuesday morning seeing red — literally.The city took on a strange rose hue throughout the day, wowing residents and leading to plenty of theories. CBC North’s Nick Murray snapped a photo of the colouration outside CBC’s Iqaluit bureau, which was shared widely across Facebook and Twitter. By Wednesday afternoon, the photo had reached nearly 200,000 people on CBC’s Facebook pages alone.

Businessman buys photograph of a potato for €1m

A celebrated photographer has sold a picture of an Irish potato for €1m (£750,000). Kevin Abosch, 46, confirmed he had sold the photograph of an organic potato shot on a black background to an unnamed European businessman.  The photograph, which was taken in 2010, sits alongside shots of Steven Spielberg, Michael Palin, Facebook’s Sheryl Sandberg and Malala Yousafzai in the sought-after photographer’s portfolio.  Mr Abosch’s portraits are typically commissioned for at least £200,000.

Happy 50th birthday Action Man – BBC News

It is 50 years since Action Man, the must-have toy of the 1970s, arrived in the UK.The plastic moulded figures, rebranded from the US GI Joe version, made their debut in the UK at the British Toy Fair in Brighton, in January 1966, after a toy executive realised their market potential.The early toys were imports but Palitoy, based in Coalville, Leicestershire, would go on to make its own version with “lifelike hair”, “beards” and “gripping hands” in the early 1970s.According to Rob Burman, editor of the Collectors Gazette, Palitoy bosses gave strict instructions not to call them “dolls” as boys could be put off.

Surprise! Zebra Stripes Are Not For Camouflage – Forbes

Contrary to what’s often assumed, the black-and-white bands aren’t used for camouflage.According to the traditional theory, stripes allow a zebra to hide against similar-looking backgrounds. In woodland areas, the black bands would resemble tree trunks while white bands are like shafts of light shining through the trees. And on the African plains, that banding pattern would break-up the outline of the body, making an animal less clearly visible to a predator. This hypothesis was debated by the founders of natural selection, Alfred Russel Wallace and Charles Darwin.

Engineers develop the refrigerator of the future

Cooling is a hugely important process in today’s world. But how can cooling be carried out in future in a way that does not harm the climate and that helps to conserve natural resources? The approach taken by Professors Stefan Seelecke and Andreas Schütze from Saarland University focuses on systems that use shape memory materials, also known as ‘metal muscles’ or ‘artificial muscles’. Working together with researchers in Bochum, they are developing a new method of cooling in which heat and cold are transferred using ‘muscles’ made from a nickel-titanium alloy. Extensive series of tests have yielded results that are now being used to develop a prototype cooling circuit that will be used to further increase the efficiency of the process. The German Research Foundation (DFG), which has been funding the project for the last three years, has agreed to invest a further 500,000 euros. In total, the project has brought around 950,000 euros in funding to the region.

Head-on collision between Earth, Theia likely created the moon – Redorbit

The collision between Earth and the “planetary embryo” known as Theia that took place roughly 100 million years after our planet formed was most likely responsible for forming the moon, according to new research published Friday in the journal Science.

While the high-velocity impact between Earth and Theia has been well documented by scientists, previous studies had suggested that the two objects simply side-swiped one another. However, in their new paper, Edward Young, a professor of geochemistry and cosmochemistry at UCLA, and his colleagues have found new evidence suggesting that it was a head-on impact.

Am I getting a good price for that? my lesson in price sensitivity | Chris-Warburton.com

I recently had an issue with my car.Having driven the car over significant mileage over the last 12 months and leaving aside any comments about my driving style, I needed a new clutch mechanism.So I went off to the nearest dealer to get it assessed and fixed. Quote £2,000…. Ouch that is nearly C$4,000It seemed extreme and rather than just accept the price, I decided to shop around.

Black hole’s twin jets shine bright, somehow – BBC News

Astronomers have published new images of a bright jet of material, long enough to cross the Milky Way three times, fired into space by the black hole at the heart of a distant galaxy.The observations confirm the existence of a second jet, blasting in the opposite direction.The study uses this galaxy, Pictor A, to test ideas about what makes jets like these emit very bright X-rays.It appears in the Monthly Notices of the Royal Astronomical Society.

Young people flock away from social media – Business Insider

When my digital media students are sitting, waiting for class to start and staring at their phones, they are not checking Facebook. They’re not checking Instagram, or Pinterest or Twitter.No, they’re catching up on the news of the day by checking out their friends’ Stories on Snapchat, chatting in Facebook Messenger or checking in with their friends in a group text.
