Atmospheric methane removal: A promising but challenging climate solution
Technology tamfitronics Methane is currently responsible for about one-third of global warming. This greenhouse gas is about 80 times more potent than carbon dioxide in terms of its ability to heat up the climate system, though methane molecules only persist in the atmosphere for seven to 12 years before breaking down.Methane emissions are a major cause for concern, as they’ve been increasing at record speeds the past five years. At least two-thirds of annual methane emissions now come from human activities,...
Webb Detects Methane Emission from Cold Brown Dwarf
NASA Space Technology Astronomers the state of the NASA/ESA/CSA James Webb Apartment Telescope admire detected methane emission from CWISEP J193518.59-154620.3 (W1935 for transient), an isolated brown dwarf with a temperature of roughly 482 Okay. Their findings furthermore suggest that W1935 could maybe well generate aurorae the same to these viewed on our admire planet to boot as on Jupiter and Saturn.An artist’s impact of the brown dwarf W1935. Image credit rating: NASA / ESA / CSA / L. Hustak, STScI.W1935 is found round 47 gentle-years away in the constellation of Sagittarius.The brown dwarf used to be co-discovered by Yard Worlds: Planet 9 citizen science volunteer Dan Caselden and NASA’s CatWISE crew.The mass for W1935 isn’t well diagnosed but it likely ranges between 6 and 35 times the mass of Jupiter.After having a seek for at a...
