Astronomers eagerly await the launch of the $8 billion James Webb Space Telescope. It will see back in time farther than any space telescope ever has before-back to the first light following the big bang. It will watch the first stars and galaxies form. And it will hunt for distant habitable planets by peering into their atmospheres. Expectations are high for the science that will come from the $8.7 billion James Webb Space Telescope-the successor to the Hubble Space Telescope. The telescope's four main science instruments are now all in one place, as are its 18 mirror sections. When assembled in space, they will create the largest orbiting mirror ever seen.

Western Antartica's immense glaciers are melting fast and giving up ice to the sea at a rate that is considered already past "the point of no return," according to recent research work done by two different groups of scientists. The resulting scenario is compelling: an increase in the world sea levels of 4 feet or more in the next centuries, according to findings announced Monday by scientists from the University of Washington, the University of California-Irvine and the Jet Propulsion Laboratory at NASA. "It truly is a startlingly disturbing situation," says Pennsylvania State University glaciologist Sridhar Anandakrishnan, who was not associated with any of the research studies. "This is a big part of West Antarctica, and it appears to have been pushed violently over the edge." The researchers claim the glaciers are most certainly bound to be lost. One study confirms that a river of ice named Thwaites Glacier is possibly starting to collapse and that complete collapse is likely to occur. A second research illustrates that six glaciers are giving up ice into the sea at an ever-increasing rate. At that rate, there will be a 4-feet increase in the sea-level, states study author Eric Rignot, a glaciologist at the University of California-Irvine, and NASA's Jet Propulsion Laboratory.
