Antarctica's coastal glaciers are shedding icebergs more rapidly than nature can replenish the crumbling ice, doubling previous estimates of losses from the world's largest ice sheet over the past 25 years, a satellite analysis showed on Wednesday.The first-of-its-kind study, led by researchers at NASA's Jet Propulsion Laboratory (JPL) near Los Angeles and published in the journal Nature, raises new concern about how fast climate change is weakening Antarctica's floating ice shelves and accelerating the rise of global sea…

Nasa's much celebrated James Webb Space Telescope is just weeks away from full operation.The huge telescope plans to start it's in-depth science investigation by exploring strange, new rocky worlds in unprecedented detail.According to Nasa, it will study two hot exoplanets classified as "super-Earths" for their size and rocky composition: the lava-covered 55 Cancri e and the airless LHS 3844 b.The telescope aims to study geology on these small planets from "50 light-years away", officials said in a statement.Researchers…
