![]() ![]() That aspect ratio is greater than that of any asteroid or comet observed in our solar system to date. The object, named ‘Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long and highly-elongated-perhaps 10 times as long as it is wide. The first confirmed object from another star to visit our solar system, this interstellar interloper appears to be a rocky, cigar-shaped object with a somewhat reddish hue. Image Credit: European Southern Observatory / M. The aspect ratio of up to 10:1 is unlike that of any object seen in our own solar system.

It's expected to start observations in 2027. The European Southern Observatory, which is run by 16 European nations and partners with Chile and Australia, has already started building its own Extremely Large Telescope in Chile. government invests in a telescope, U.S.-based astronomers get a share of the viewing time regardless of where in the world it is built. to remain a leader in ground-based astronomy. The report said the success of at least one of these two projects-TMT or Magellan-was a critical priority due to their "transformative scientific potential." It concluded that having at least one was "absolutely essential" for the U.S. astronomers included this recommendation in their once-in-a-decade analysis of their priorities and goals called the Pathways to Discovery in Astronomy and Astrophysics for the 2020s. The Giant Magellan Telescope project, to be built in Chile, would observe the universe from the Southern Hemisphere. TMT would cover the skies from the Northern Hemisphere. astronomy community said in a report that the National Science Foundation should invest in at least one or two of a new class of observatories called Extremely Large Telescopes being planned by U.S. "Why don't people accept our 'no' for the answer?" said Pisciotta, who is a spokesperson for the groups Mauna Kea Hui and Mauna Kea Aina Hou that oppose the project. Telescope opponents criticized the new study, saying it will force them take time away from their lives again to give their views about the project, said Kealoha Pisciotta. ![]() "This ensures that the TMT tests the best ideas and does the most important observations to contribute to understanding where we are in the universe and how it works," he said. TMT is a partnership between the California Institute of Technology, the University of California and government-backed research institutions in Canada, China, India and Japan. ![]() astronomy community last year said TMT planned to obtain 30% of the project's estimated construction costs, or $800 million, from the U.S. law to invest in the project because it is part of the federal government.Ī report from the U.S. The National Science Foundation must conduct a new study under U.S. The group completed an environmental study in 2010 that was mandated by Hawaii law for construction on Mauna Kea. The TMT International Observatory, the international consortium of scientists behind the project, has selected the Spanish island of La Palma off Africa's western coast as an alternate if it cannot build in Hawaii. Protesters blocked construction crews in 20, saying building a new telescope there would further defile a site that they say has already been harmed by a dozen other observatories. It said it won't decide on whether to fund the telescope until after it considers public input, the environmental review, the project's technical readiness and other factors. The National Science Foundation plans to host four meetings on the Big Island of Hawaii in August. But there is strong opposition from Native Hawaiians who consider the mountain's summit sacred. The telescope's supporters have pursued plans to build it on their preferred site on the summit of Mauna Kea, Hawaii's tallest mountain and one of the world's best locations for viewing the night sky, for over a decade. The agency published a notice in the Federal Register of its intentions to prepare an environmental impact statement for the $2.65 billion Thirty Meter Telescope. ![]()
