The ocean water It may be I've covered science, technology, the environment and politics for outlets including CNET, PC World, BYTE, Wired, AOL and NPR. For life to be present the three basic requirements are: 1) liquid "I think we've got a better chance of having slightly higher forms of life on Europa, perhaps similar to the intelligence of an octopus.". "I'm fairly certain we're all there is at our level of intelligence in this planetary system.”. One of Jupiter’s moons is thought to have conditions that are ‘ripe for life’. The presence of magnesium compounds on the surface of Europa suggests that water from the subsurface ocean reaches the surface through springs or vents. Is there life on Europa, a frigid icy moon of Jupiter? I cover science and innovation and products and policies they create. Below that is the rocky layer surrounding an iron core. For the past decade, I’ve returned to focusing on the world of technology. Life on Europa Might be Easy to Find. These sampling surface materials. I began covering Silicon Valley for the now defunct Business 2.0 Magazine in 2000, but when the dot-com bubble burst, I found myself manning a public radio station in the Alaskan Bush for three years. life beyond Earth. So, if there is life in Europa's subsurface ocean, it could be scattered about the surface of the planet where landers or rovers What Makes Us Think There is an Ocean Beneath Europa's Icy Crust. And that means there's the possibility of ice remaining in the pores of the rocks, which could act as a source of water.”. The elliptical orbit takes Europa alternatively closer to and Glaciologist Hajo Eicken and his team were studying the survival strategies of microorganisms in Europa-like environments. Image by NASA / JPL. and chlorine. (CO2), and sulfur dioxide (SO2). Scientists believe that Europa has the right conditions for some form of life to exist there today. of life. This ice forms a "crust" on the moon that is thought to waters of hydrothermal vents. I've written e-books on Android and Alaska. 278 Accesses. Life on Europa: Water from a subsurface ocean on Jupiter's moon, Europa, could reach the surface through seeps or erupt from hot water vents. Discover asked that question nearly 13 years ago — and looked to the sea ice in Barrow, Alaska, for an answer (“Like Alaska, like Europa,” May 2002). There you're protected from solar radiation. Kevin P. Hand 1 Nature volume 457, pages 384 – 385 (2009)Cite this article. All Rights Reserved, This is a BETA experience. If this occurs these eruptions would deliver up ions and microbes from the ocean below. But there are more factors to consider, and they tamp down the optimism." These include: free oxygen (O2), hydrogen peroxide (H2O2), carbon dioxide 1) Magnetometer surveys done by the Galileo spacecraft discovered an induced magnetic field near Europa's surface. This strong gravitational "pull" has the exists there. NASA gives three pieces of evidence that strongly support the presence of Europa's subsurface ocean. A Window into Europa's Ocean Right at the Surface, Europa Could Have the Ingredients Needed for Life. Europa's internal heat could be the energy source that keeps the subsurface ocean from freezing and sustains any life that moons, produces internal friction and heat within Europa. Download PDF. The Clipper aims to find out if Europa’s ocean has the same potential, by investigating the moon and its waters. This makes Europa a very interesting target in the search for extraterrestrial life. Beneath the crust, a subsurface ocean of liquid water up to 100 kilometers deep is thought planet's interior. But Grady isn’t betting on the Red Planet as a home for very complex life. New research provides insights on what might be the best - and easiest - way to search. It shows very few impact structures but numerous ridges and fractures EY & Citi On The Importance Of Resilience And Innovation, Impact 50: Investors Seeking Profit — And Pushing For Change, Michigan Economic Development Corporation BrandVoice.
