Following their six-month stay aboard the International Space Station, the members of NASA's SpaceX Crew-6 mission are safely back on Earth. NASA astronauts Stephen Bowen and Woody Hoburg and UAE (United Arab Emirates) astronaut Sultan Alneyadi will speak about their mission for the first time after returning to Earth on Sept. 4, answering questions from media and the public. Fellow crew member Andrey Fedyaev of Roscosmos is unable to participate in the news conference due to travel. During the mission, Bowen and Hoburg completed two spacewalks, and Alneyadi became the first UAE astronaut to conduct a spacewalk. With 10 spacewalks throughout his missions, Bowen ties the record for most excursions by a U.S. astronaut, also held by four others. While aboard the station, Crew-6 contributed to hundreds of experiments and

This artist’s rendering illustrates new findings about a star shredded by a black hole. When a star wanders too close to a black hole, intense tidal forces rip the star apart. In these events, called “tidal disruptions,” some of the stellar debris is flung outward at high speed while the rest falls toward the black hole. This causes a distinct X-ray flare that can last for a few years. NASA’s Chandra X-ray Observatory, Swift Gamma-ray Burst Explorer, and ESA/NASA’s XMM-Newton collected different pieces of this astronomical puzzle in a tidal disruption event called ASASSN-14li, which was found in an optical search by the All-Sky Automated Survey for Supernovae (ASAS-SN) in November 2014. The event occurred near a supermassive black hole estimated to weigh a few million times the mass of the sun in the center of PGC 043234, a galaxy that lies about 290 million light-years away. Astronomers hope to find more events like ASASSN-14li to test theoretical models about how black holes affect their environments. During the tidal disruption event, filaments containing much of the star's mass fall toward the black hole. Eventually these gaseous filaments merge into a smooth, hot disk glowing brightly in X-rays. As the disk forms, its central region heats up tremendously, which drives a flow of material, called a wind, away from the disk. Music credit: Encompass by Mark Petrie from Killer Tracks.
