How and when a supermassive black hole consumes material?

NASA Space Technology A team of researchers used data from NASA’s Chandra X-ray Observatory, Neil Gehrels Swift Observatory, and ESA’s XMM-Newton to offer a new understanding of how and when a supermassive black hole consumes material.In 2018, the optical All Sky Automated Survey for SuperNovae noticed a system called AT2018fyk, in which a black hole partially disrupted a star.ASAS-SN noticed this system had become much brighter. When scientists observed it with NASA’s NICER (Neutron Star Interior Composition Explorer) and Chandra and XMM-Newton, they found that the brightness came from TDE, which signifies that a black hole partially ingested a star after flying too close to a black hole.The material from the star got hotter and produced X-ray and ultraviolet (UV) light as it approached close to the black hole. These signals then faded, suggesting nothing...

NASA Space Technology Illustration: Blue Origin The White House announced earlier this year it would implement a unified time standard for the Moon by 2027, an essential measure as NASA aims to establish a permanent presence on the lunar surface. Two Colorado-based researchers proposed a solution in a recently published scientific paper involving clocks floating in space to calculate the time difference between the Earth and the Moon. Suggested ReadingHow Starbucks can succeed, according to a former Amazon execSuggested ReadingHumanity has never contended with the differences in time zones between two celestial bodies. To use terrestrial terms, the time difference between the Eastern and Pacific time zones in the U.S. is three hours. It’s fixed and doesn’t change. It’s always three hours. That’s not the case between planets and moons because of relativity. Time...

NASA Space Technology Astronomers using the NASA/ESA Hubble Space Telescope have produced a beautiful image of the barred spiral galaxy UGC 11861.This Hubble image shows UGC 11861, a barred spiral galaxy located 69 million light-years away from Earth in the constellation of Cepheus. Image credit: NASA / ESA / Hubble / C. Kilpatrick.UGC 11861 lies in the northern constellation of Cepheus, approximately 69 million light-years away.Otherwise known as LEDA 67671, IRAS 21557+7301 or TC 609, the galaxy is classified as a barred spiral galaxy and a candidate active galactic nucleus.UGC 11861 is composed of an exponential disk, a central boxy structure and two broad spiral arms.“Among the cloudy gases and the dark wisps of dust, this galaxy is actively forming new stars, visible in the glowing blue patches in its outer arms,” the Hubble astronomers...

NASA Space Technology NASA has awarded a total of $1.25 million to three U.S. teams in the third and final round of the agency’s Deep Space Food Challenge. The teams delivered novel food production technologies that could provide long-duration human space exploration missions with safe, nutritious, and tasty food.The competitors’ technologies address NASA’s need for sustainable food systems for long-duration habitation in space, including future Artemis missions and eventual journeys to Mars. Advanced food systems also could benefit life on Earth and inspire food production in parts of the world that are prone to natural disasters, food insecurity, and extreme environments.“The Deep Space Food Challenge could serve as the framework for providing astronauts with healthy and delicious food using sustainable mechanisms,” said Angela Herblet, challenge manager for the Deep Space Food Challenge at NASA’s Marshall...
