Researchers analyzing archival observations from NASA’s Hubble Space Telescope found a chemical signature suggesting the white dwarf HS 0209+0832 may host a second-generation planet. The finding, reported in Nature Astronomy, shows how existing space-telescope data can yield new evidence about planetary systems around stellar remnants.

NASA is seeking ideas to mitigate static electricity that could build up on astronauts and critical hardware during Moon missions. The agency says charged lunar explorers could act like “walking, high voltage capacitors,” posing a risk of accidental discharges to spacecraft and equipment.
NASA’s X-59 experimental aircraft reached Mach 1.53 during a four-day campaign of six flights, setting a new speed record for the supersonic demonstrator. The flights expanded its flight envelope as NASA tests technology intended to enable quieter supersonic flight over land.
Growing fresh food on the Moon could help move astronauts beyond freeze-dried rations, but doing so depends on managing water in lunar conditions. The article examines how water might flow there, a basic resource challenge for efforts to cultivate food during future lunar missions.

NASA has released the final request for proposals for the next phase of its program to develop commercial space stations. The solicitation moves the procurement beyond the earlier draft stage, inviting proposals for the effort’s next phase.
NASA has released its final request for proposals inviting U.S. industry to develop, certify and operate privately owned space stations. The solicitation sets out how the agency plans to procure commercial destinations as it prepares for operations beyond the International Space Station.
Teams behind the James Webb and Hubble space telescopes have released new images capturing stellar nurseries, galaxies and gravitational lensing. Webb is jointly operated by NASA and the European Space Agency, with the Canadian Space Agency also participating; both observatories contributed to the latest collection.
