NASA’s Nancy Grace Roman Space Telescope is scheduled to launch on August 30, 2026, beginning a wide-field infrared mission designed to investigate cosmic expansion, unseen matter and planetary systems.
A newly identified star, S301, has set the speed record for known stars in the Milky Way and may offer an unusually direct way to measure the spin of the Galaxy’s central black hole.
NASA’s cancelled effort to lift the Swift observatory illustrates both the scientific value of ageing spacecraft and the unforgiving limits of hurried in-orbit servicing.
NASA has ended the attempt to raise the orbit of the Neil Gehrels Swift Observatory after faults on the commercial servicing spacecraft LINK made a capture unsafe, but the mission will still test selected rendezvous capabilities.
A newly identified star orbiting Sagittarius A* may offer astronomers their best practical opportunity yet to measure the spin of the Milky Way’s central black hole directly.
The celebrated solar-neutrino mystery was resolved in 2001, but new measurements are refining the particle physics that emerged from that breakthrough.
