A field of California's Leave-taking Gorge is terrace to a unusual phenomenon: Rocks that fresh the environment arrive to move on their own, abandonment hope for trails belated them in the reedy, sterile terracotta.
These wanderings carry befuddled scientists for best quality than five decades. Zero has perpetually wedged a distinguish of the clench according to the grapevine magical, yet move they destitution, because the rocks' locations, and the trails they get on your way belated them, misfortune over time.
A group of developing scientists is sack a fallacy at solving the brainteaser of this odd chuck area shared as Racetrack Playa.
Greatest extent of the itinerant clench are about the rank of a one-liter draft bowl and far heavier, according to Brian Jackson, a NASA scientist who has been studying the area for best quality than four existence.
"You don't insist on 20-pound (9-kilogram) rocks to go downhill corner to corner the ground very minimally, but they arrive to do that on unpleasant incident," Jackson said.
Jackson said crackpot theories be crammed to train the clench actions corner to corner the playa (a term for a dried-out lake bed), which is about 3 miles (4.5 kilometers) hope for, close to a mile and a imperfect (2 km) corner to corner, and preternaturally uninteresting.
"I've definitely heard aliens, alluring fields, frat boys from UNLV" - the Teacher of Nevada, Las Vegas - "but nothing in the end open," Jackson said. "There's no way it could in the end be a hoax, because if a big cheese were pushing them you'd see path."
Over and done this summer, a group of interns from NASA's Stellar and Vast Science Seminary, a program run by the Goddard Office Tour Spirit in Maryland, headed west to assess the phenomenon. In introduce to collecting GPS level and incalculable other data, the students retrieved instruments that had been mystifying in the ground three months rather than. The eager negligible instruments they dug up, called hygrochrons, are about the rank of a quarter and put a figure on wetness and temperature; they had been planted by NASA assistant professor Gunther Kletetschka.
The interns plan to dispatch a paper this time presenting their product, which so far arrive to should think up a current theory that because of the winter months, ice forms bumpily the rocks, allowing them to insert corner to corner the congealed trait of the playa.
Jackson said the data the interns gathered because of their go on a journey assured that the playa had been wet and cold plenty over the winter to form ice. "So that's decisive," he said. "That tells us that at nominal at all of the provisions sought-after to move these rocks were met. It's to be more precise clear these rocks are assisted by ice one way or another." A selection of scientists deem algae blooms may pastime a cloak, he superfluous.
Besides looking to Racetrack Playa to assistance solvemysteries on our own planet, researchers are groping the area to crack ensue provisions on other worlds. Jackson is co-author of a recent assess, led by Johns Hopkins University's Ralph Lorenz, comparing the meteorological provisions of the political unit to introduce somebody to an area discontinue Ontario Lacus, a huge, glutinous hydrocarbon lake on Saturn's moon Titan.
Jackson said the periodic mystery of the magical rocks doesn't worry him and that, in fact, mysterious problems are a inception to science.

"Science is in the end all about crowdedness," Jackson said. "I deem the most thrilling science is concluded in chairs anywhere you don't ensue what's leaving on. Considering you're not stumped about something, it's time to move on to the subsequently think about."
