Processes not involved in controlling sand movement on Earth play major roles on Mars, report planetary scientists.
This week, from March 20th to 24th, the 48th Lunar and Planetary Science Conference will be taking place in The Woodlands, Texas. Every year, this conference brings together international specialists in the fields of geology, geochemistry, geophysics, and astronomy to present the latest findings in planetary science. One of the highlights of the conference so far has been a presentation about Mars’ weather patterns.
Researchers from the California Institute of Technology have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The newly discovered world, which the researchers have nicknamed Planet Nine, is extimated to be 10 times more massive than earth and 4 times its size. It orbits about 20 times farther from the sun on average than Neptune (which orbits the sun at an average distance of 2.8 billion miles). It would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun.
