The results strengthen tests of general relativity by reading horizon-scale signatures in the post-merger ringdown. Young supernova remnant near Sgr A* - Chandra and XMM-Newton data point to a possible supernova remnant in the Sagittarius C region near the Milky Way’s central black hole, Sagittarius A*. If confirmed, the roughly 1,700-year-old remnant would illuminate how star death, shocks, and chemical enrichment shape the Galactic Center environment. Asteroid 1997 NC1 flies by - A roughly kilometer-wide potentially hazardous asteroid, 1997 NC1, passed Earth safely at about 1.5 million miles, offering a real-world planetary-defense case study. The flyby highlighted both effective tracking and the importance of continued detection and orbit refinement for near-Earth objects. Robotic mission to boost Swift - NASA and commercial partner Katalyst Space are preparing a first-of-its-kind robotic servicing attempt to capture the aging Swift observatory and raise its orbit. The Swift Boost plan aims to extend a key high-energy astronomy mission while demonstrating new tools for space sustainability. Launch cadence, Roma…
