JWST finds a mature barred spiral galaxy in the infant universe

A study posted to arXiv pushes one of galaxy evolution’s most important milestones deep into cosmic history. Researchers led by Xiaohan Wang of Tsinghua University report that JWST, with support from the Hubble Space Telescope, has identified M1149-BSG-z5, a massive barred spiral galaxy candidate seen when the universe was less than 1.2 billion years old.…

The International Space Station orbiting above Earth

Humans have lived continuously aboard the International Space Station since November 2, 2000, extending an unbroken off-world presence beyond 25 years, keeping at least one person in orbit every day and creating the longest sustained period that members of our species have lived away from Earth

NASA Johnson Space Center has marked more than 25 years of continuous human life aboard the International Space Station. The unbroken period began when the Expedition 1 crew entered the orbiting laboratory on November 2, 2000. Every day since then, at least one person has been living beyond Earth’s atmosphere. The milestone represents roughly 9,000…

Kepler ended decades of uncertainty over whether Earth-like worlds were cosmic accidents by revealing that small planets are common and suggesting at least 300 million potentially habitable worlds may orbit Milky Way stars, while TESS maps nearby candidates and the enduring silence leaves astronomers asking why a galaxy that may teem with planets still seems so quiet

A study led by researchers at NASA Ames used Kepler’s final planet census to estimate how often rocky worlds occupy temperate orbits around Sun-like stars. The analysis, published in The Astronomical Journal, suggested that the Milky Way could contain at least 300 million potentially habitable planets. The result marks a profound change in astronomy. A…

At 65, Peggy Whitson became the oldest woman to orbit Earth when she commanded the privately funded Axiom Mission 4, leading a four-person crew from four nations to the International Space Station for 18 days and raising her career total beyond 695 days, the longest time in space accumulated by any American astronaut or any woman in history

Axiom Space’s official profile records a spaceflight career without equal among American astronauts or women. At age 65, Peggy Whitson commanded Axiom Mission 4 to the International Space Station. The flight made her the oldest woman to reach Earth orbit and increased her cumulative time in space to 695 days, 7 hours and 4 minutes.…
