    [In Depth] ‘Brexit’ casts pall on future of U.K. science (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-07-01
    Description: Days after the United Kingdom's momentous vote in favor of leaving the European Union, the U.K. science community is seething with anxiety. No one knows whether U.K. science will struggle or thrive when the divorce goes ahead. Neither the U.K. government nor the European Commission had thought through beforehand how U.K. research could untangle itself from the European enterprise—or whether it even needs to. Scientists have pressing and practical questions: Can U.K. researchers continue to apply for E.U. grants? Will reviewers looking at a proposal involving U.K. scientists wonder about their commitment? Will U.K. postdocs have trouble taking up positions on the continent? What is the future for E.U. facilities on U.K. soil? Author: Daniel Clery

    [In Depth] Brexit casts pall on fusion (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-06-17
    Description: If the United Kingdom votes to leave the European Union on 23 June, fusion research may be particularly hard hit. Europe's largest fusion facility, the Joint European Torus (JET), is sited near Oxford, U.K.; a vote to leave would put it in a legal limbo that could halt vital research supporting the International Thermonuclear Experimental Reactor (ITER), now under construction in France. JET is the world's largest fusion reactor; its innards have been coated with the same beryllium and tungsten that will line ITER; and its heating power boosted to make it as ITER-like as possible. JET researchers are testing how the machine behaves when filled with individual hydrogen isotopes before attempting burns with deuterium and tritium—the fuel for fusion—in 2019. A Brexit could halt those experiments. Author: Daniel Clery

    [In Depth] In search of spacetime megawaves (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-03-11
    Description: Last month, the detection of gravitational waves from merging black holes made headlines and tweetstorms around the world. But a hunt for much bigger game was already afoot. The black holes responsible for last month's discovery weighed a few dozen times as much as our sun. Black holes millions or billions of times that massive, however, lurk at the centers of most galaxies—and they merge, too, creating waves like gravitational tsunamis. Three teams of radio astronomers are watching the heavens for hints of these megawaves, which should cause hiccups in the ultraregular pulses of distant energy beacons called millisecond pulsars. The researchers' latest results suggest that increasing sensitivity should enable them to see signs of the waves sometime in the next decade. Author: Daniel Clery

    [In Depth] More delays for ITER, as partners balk at costs (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-05-06
    Description: Last week, an independent review committee delivered a report that was supposed to show that ITER, the troubled international fusion experiment under construction in Cadarache, France, finally has a reliable construction schedule and cost estimate. But the report says only that the new date for first operations—2025, 5 years later than the previous official target—is the earliest possible date and could slip. And it underscores the challenge of ITER's ballooning budget. To start running by 2025, ITER needs an extra €4.6 billion that its member states are reluctant to provide. As a result, the report says, its ultimate goal—a fusion reaction that gives off more energy than it consumes—will be delayed from 2032 until 2035 at the earliest. Authors: Daniel Clery, Adrian Cho

    [In Depth] Kepler enlists relativity to find planets (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-04-29
    Description: Back in business after a heart-stopping near-shutdown in April, NASA's Kepler space telescope is about to begin an 80-day campaign to search for exoplanets using a novel technique. Called gravitational microlensing, it's based on Einstein's discovery that gravity bends light. That means massive objects in space can act as lenses, focusing the light from objects even farther from Earth. Astronomers have found many cases in which galaxies distort the images of quasars. Microlensing works on a much smaller scale: Individual stars or planets focus the light of more distant stars, making the background star appear to grow brighter and then dim again. By measuring those rising and falling "light curves," Kepler will give astronomers valuable information about planets orbiting other stars—including exoplanets in far-out orbits that other techniques can't detect—and even free-floating planets that don't orbit stars at all.

    [In Depth] Rosetta ends 2-year comet mission with final descent (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-09-30
    Description: All good things must come to an end, and so it will be on 30 September when the Rosetta spacecraft makes its planned soft landing onto the surface of comet 67P/Churyumov-Gerasimenko, the culmination of 2 years of close-up studies. Solar power has waned as 67P's orbit takes it and Rosetta farther from the sun, and so the mission team decided to go on a last data-gathering descent before the lights go out. This last data grab is a bonus after a mission that is already changing theorists' views about how comets and planets arose early in the solar system. Several Rosetta observations suggest that comets form not from jolting mergers of larger cometesimals, meters to kilometers across, but rather from the gentle coalescence of clouds of pebbles. And the detection of a single, feather-light, millimeter-sized particle—preserved since the birth of the solar system—should further the view of a gentle birth. Author: Daniel Clery

    [In Depth] Mars lander crash adds to 2020 rover worries (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-10-28
    Description: Engineers at the European Space Agency (ESA) are racing to figure out what went wrong with the Schiaparelli Mars lander. On 19 October, it seemed to drop out of the sky and crash to the surface less than a minute before its planned soft landing. A diagnosis is urgent because many of the same pieces of technology will be used to get a much bigger ExoMars rover down to the surface in 2020. More than engineering is at stake. If the ExoMars 2020 rover is to fly at all, ESA must persuade its 22 member states to cover a €300 million shortfall in the €1.5 billion cost of the 2016 and 2020 phases of ExoMars. On 1-2 December, at a meeting of government ministers, ESA officials will make their case that members are not throwing good money after bad. Author: Daniel Clery

    [In Depth] Global telescope gears up to image black holes (2017)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2017-03-03
    Description: Last year researchers "heard" black holes for the first time, when they detected the gravitational waves unleashed as two of them crashed together and merged. Now, they want to see a black hole, or at least its silhouette. Next month, astronomers will harness radio telescopes across the globe to create the equivalent of a single Earth-spanning dish—an instrument powerful enough, they hope, to image black holes backlit by the incandescent gas swirling around them. Their targets are the supermassive black hole at the heart of our Milky Way galaxy, known as Sagittarius A*, and an even bigger one in the neighboring galaxy M87. Author: Daniel Clery

    [In Depth] U.S. observers seek a more perfect union (2017)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2017-02-03
    Description: The U.S. National Science Foundation (NSF) is aiming to merge some functions of its three largest optical observatories within a new body called the National Center for Optical and Infrared Astronomy. The new center would provide services to the Gemini Observatory (with twin 8.1-meter telescopes in Hawaii and Chile), the National Optical Astronomy Observatory with a handful of telescopes in Chile and the United States, and the still-rising Large Synoptic Survey Telescope, an 8.4-meter instrument in Chile. The fact that all three receive significant funding from NSF but each is governed by an entirely separate organization is emblematic of the fractured nature of U.S. astronomy. By pooling many functions, NSF hopes to make better use of available expertise and achieve economies of scale while preserving independent scientific operations. Author: Daniel Clery
