Hubble imaging space and time
Dave Mosher, provided by Published 12:01 pm CDT, Tuesday, October 9, 2018 NASA/ESA A vital part inside the Hubble Space Telescope, which records stunning images of the universe, failed on Friday. The part is called a gyroscope and helps Hubble point at celestial objects. It's the third of six total gyros to fail since 2009, when astronauts last serviced Hubble. Another gyro is acting "drunk," one official said. NASA may start using a single gyro to extend the telescope's lifespan, but this would limit the observations Hubble can make. When Hubble dies, NASA will have a few ways to get rid of — or rescue — the bus-sized cylinder. The Hubble Space Telescope is famous for the stunning images it records of the universe, from distant galaxies to dark storms on Neptune and even plumes of water shooting from alien moons. But the Earth-orbiting spacecraft won't last forever. NASA, the European Space Agency, and other Hubble partners got a sobering reminder of this … [Read more...] about NASA’s Hubble space telescope just lost a vital part, and one of its backups is ‘acting drunk.’ Here’s why astronomers haven’t lost hope.

Researchers studying the universe are ramping up to take the “image of the century” — the first ever image of a supermassive black hole. Since the 18th century, astronomers have discussed the possibility of exotic objects in space so massive that their gravitational grip swallows everything that dares to get too close, including light. We call these objects, black holes, but in truth we do not know what a black hole really is because we’ve never actually seen one. While the evidence for the existence of black holes is compelling: “We have abundant evidence that black holes — or something very much like them — exist,” Todd Thompson, astronomy professor at Ohio State University, told Business Insider earlier this year. “This evidence comes from the orbits of stars around the supermassive black hole at the center of our galaxy.” Scientists will continue to argue the contrary until physical, observational evidence is provided. … [Read more...] about How Astronomers Will Take The ‘Image Of The Century’ — Our First Glimpse Of A Black Hole
Construction crews have broken ground on the Giant Magellan Telescope in Chile. When complete, the telescope will have a light-collecting area about 80 feet in diameter – nearly the area of a basketball court. GMT’s photos will be about 10 times sharper than those of NASA’s Hubble Space Telescope. Laser-based optics will help the $US1-billion telescope “sniff” the atmospheres of potentially habitable exoplanets. In astronomy, cutting-edge technology often begins with a bunch of bulldozers, busted rocks, and dump trucks. So it goes with the Giant Magellan Telescope (GMT), which will the world’s largest and most powerful when it sees “first light” in 2024. Astronomers hope to use the huge observatory to study the ancient universe and look for signs of alien life. Construction crews atop a Chilean mountain range broke ground for the $US1 billion project on Tuesday. The final device will weigh more than 2 million lbs, so workers are … [Read more...] about A $1 billion telescope that will take pictures 10 times sharper than Hubble’s is now officially under construction
