One example got underway when NASA’s Curiosity Rover crossed a dune field on the red planet in 2015. Observations from Mars have already changed the way scientists think about the physics of sedimentary processes on Earth. “Sometimes when exploring another planet, you make an observation that challenges your understanding of geological processes, and that leads you to revise your models.”Īssistant Professor of Geological Sciences, Stanford Earth Alien forms In the coming years, studies of these bodies may well alter the way we think about our place in the universe. “The multitude and variety of planetary bodies within and beyond our solar system,” they write in a paper published March 2, “might be key to resolving fundamental mysteries about the Earth.” Now, as telescopes acquire more power, exoplanet studies grow more sophisticated and planetary missions produce new data, there’s potential for much broader impacts across Earth sciences, as Lapôtre and co-authors from Arizona State University, Harvard University, Rice University, Stanford and Yale University argue in the journal Nature Reviews Earth & Environment. Efforts to explain processes closer to the ground – at Earth’s surface and deep in its belly – are only beginning to benefit from knowledge gathered in space. Yet revelations have not permeated all geoscience fields equally. Studies of space have helped to explain aspects of climate and the physics of nuclear winter, for example. More recently, researchers have recognized planetary exploration as a two-way street. Scientists since Galileo have sought to understand other planetary bodies through an earthly lens. It’s also a way for us to learn things about the planet that’s under our own feet,” said Lapôtre, an assistant professor of geological sciences in the School of Earth, Energy, & Environmental Sciences (Stanford Earth). “We don’t only look at other planets to know what’s out there. For Stanford planetary geologist Mathieu Lapôtre, “home” encompasses the entire Earth. Sometimes, you need to leave home to understand it.

That includes our scientific explorations. Postal service spokesman Roy Betz said the images on each of the 20 to 25 new stamps issued each year are suggested by the public, and those that make the cut often are subjects that send people to the Internet to learn more. And for die-hard Pluto fans, the site also has a couple of petitions seeking to restore it to full planet status. The online petition, which can be found on the website, had already gathered more than 6,400 signatures as of Thursday.

He resisted the idea of capturing Pluto's distance by showing the sun in the background as a tiny speck, or the planet's surface cast in shadow “in the dim, dark, cold recesses of the solar system.” Sources: NASA, wire reports, and Express-News archives Using the Hubble Space Telescope, astronomers discovered a fourth moon orbiting Pluto in 2011. If you weigh 100 pounds on Earth, you would weigh 8 pounds on Pluto. Minimum/maximum surface temperature: -387/-369 degrees F. 24, 2006.Īverage distance from the Sun: 3.67 billion miles. Reclassified as a dwarf planet by the International Astronomical Union on Aug. Named by Venetia Burney, 11, of Oxford, England, after her grandfather passed her suggestion on to the observatory. Discovered by Clyde Tombaugh, a junior astronomer, at Arizona's Lowell Observatory, on Jan.
