The 'Floating Hills' of Pluto (Photo)
Hills of water ice on Pluto 'float' in a sea of frozen nitrogen and move over time like icebergs in Earth's Arctic Ocean รข€” another example of Pluto's fascinating geological activity. Credit: NASA/JHUAPL/SwRI Mini-mountains of water-ice creep across Pluto's surface, carried slowly along by the dwarf planet's nitrogen-ice glaciers, a newly released photo suggests. The image, which was captured by NASA's New Horizons spacecraft during its historic Pluto flyby last July, shows that the ..>> view originalDeep-Sea Creature 'Purple Socks' May Hold Clue To Evolution Of Animal Life
Researchers from Australia and the United States have discovered four new species of purple sock-like creatures that belong to the genus Xenoturbella. This allowed them to identify the placement of the creatures in animal tree of life. (Photo : Greg Rouse | Scripps Oceanography) An international team of scientists from Australia and the United States may have finally determined the identity of a worm-like animal that had baffled Swedish biologists for close to six decades. Since the discovery..>> view originalSaturn's ring mystery: Why are opacity and density a mismatch?
In studying the mass of Saturn’s rings, astronomers have stumbled on a surprising finding: more opacity does not necessarily mean more mass, as one might expect."Appearances can be deceiving," Phil Nicholson, an astronomy professor at Cornell University, said in an announcement."A good analogy is how a foggy meadow is much more opaque than a swimming pool, even though the pool is denser and contains a lot more water," explained Dr. Nicholson, who participated in a recent analysis of data collec..>> view originalBlack Tarantula Named After Singer Johnny Cash Among 14 New Spider Species Found In The US
Dark, charismatic and brooding -- these are words to describe famous country singer Johnny Cash, and apparently a new spider species is as fascinating as him, too. A black tarantula found among 14 new spider species in the United States is now named after the musical icon.(Photo : Dr. Chris A. Hamilton) Despite the technological and scientific advancements of the 21st century, there are a lot of things we still don't know about Earth and its inhabitants. For instance, there are 55 known specie..>> view originalPandemic Decimating Bee Populations Worldwide Is Man-Made And Driven By European Honeybees
Study found that the pandemic that is currently destroying bee populations around the world is man-made. The Deformed Wing Virus is largely driven by the European honeybee Apis mellifera populations.(Photo : Paul Rollings | Flickr) There is a disease currently destroying bee populations around the world. New study found that the disease is manmade and is being driven by the honeybee populations in Europe called the Apis mellifera. The dreaded Deformed Wing Virus is destroying bee hives around ..>> view originalCongress Scolds NASA, Underscoring How Far We Are From Mars
NASA's big Mars plan. Congress looked it over on Wednesday and found it wanting. Image from NASA It seemed like Congress was finally in the mood to appreciate NASA. After all, the federal space agency has been doing the kind of work that gets a space agency noticed the past couple of years. It pulled off the first launch of the Orion spacecraft in 2014, and then the agency followed up by discovering water on Mars and giving us unprecedented images of Pluto in 2015. And Congress responded wi..>> view originalShared noses: Extinct wildebeest relative was remarkably dinosaur-like
You might not expect to find many similarities between a mammal and a reptile, particularly if they lived millions of years apart. But scientists have found that two such extinct beasts share a rare, distinctive facial feature.An extinct relative of the wildebeest and a duck-billed dinosaur both had bizarre crests on their heads. But it wasn't the protruding bump that has most intrigued scientists, it's what they found beneath.The bony crest is hollow, forming a trumpet-shaped nasal passage unl..>> view originalJapan Volcano Erupts Close To Nuclear Plant
Japan's Sakurajima volcano has erupted, sending lava flowing down its slope and spewing ash and stones into the night sky. Dramatic pictures of the fiery spectacle also show flashes of volcanic lightning - thought to be caused by friction between ash particles and gases. The volcano, in the southern Kagoshima prefecture, has been showing increased activity since August when locals were told to prepare for a large eruption and possible evacuation. Around 4,000 people live near the volcano How..>> view originalScientists discover prehistoric 'Jurassic butterfly'
Scientists have discovered an insect that went extinct for more than 120 million years and featured many of the traits associated with modern butterflies including markings on the wing called eye spots. Known as Kalligrammatid lacewings, paleobotanists for the past century have known they lived in Eurasia during the Mesozoic. But it’s taken recent discoveries of well-preserved fossils from two sites in northeastern China to demonstrate how similar they were to modern butterflies. Thanks to exte..>> view originalPlasma physicist discusses the Wendelstein 7-X stellarator
