Rubin Observatory has revealed dwarf-planet candidate 2026 ED138 and two previously unknown companions of the Milky Way. These early discoveries highlight Rubin’s potential to transform surveys of the outer solar system, faint galaxies, star clusters, and dark matter. [123][210] Supernova winds complicate cosmic dawn - Hubble observations indicate that strong winds from supernovae may block ionizing ultraviolet light rather than help it escape. The result challenges a leading explanation for cosmic reionization and the end of the early universe’s hydrogen fog. [122] Gas trail exposes powerful microquasar - Astronomers found a narrow, 26-light-year trail of unusually warm molecular gas aligned with LMC P3. The structure provides strong evidence that jets from a black hole or neutron star power this intense gamma-ray source. [240] TRACERS maps shifting magnetic activity - NASA’s twin TRACERS satellites suggest magnetic reconnection near Earth changes mainly because the active region moves. The finding could improve scientific understanding of space weather, geomagnetic storms, communications risks, and power-grid disruptions. [130] NASA reconsiders Hubble rescue mission - NASA is asking commercial space companies for ideas to boost, service, or safely dispose of the Hubble Space Telescope. The exploratory request could shape a mission to extend Hubble’s scientific life before its orbit falls too low. [151][154] India restores vital navigation network - India successfully launched NVS-03, restoring the NavIC navigation constellation to its minimum operational configuration. The mission follows the orbital failure of NVS-02 and strengthens India’s independent positioning and timing services. [140][144] Spacewalk upgrades aging space station - Astronauts installed the seventh of eight new roll-out solar arrays during the hundredth U.S. spacewalk conducted from the International Space Station. The upgrade supports continued research and the station’s eventual controlled retirement. [182][183] Episode Transcript Rubin’s remarkable early discovery haul We begin with an impressive early haul from the Vera C. Rubin Observatory in Chile. Researchers have identified an object beyond Neptune called 2026 ED138. Its exact size is still uncertain, but its brightness suggests that it could rank among the largest known bodies in that remote part of the solar system. If later observations show that gravity has pulled it into a roughly round shape, it could become the sixth dwarf planet formally recognized in our solar system. The object was first noticed in Rubin data collected earlier
