Orbital science, astronomy, remote sensing, and what lies beyond the atmosphere.
A study in Astronomy & Astrophysics combines Webb’s infrared vision with more than a decade of Hubble observations to reveal a layered history inside Terzan 5. The crowded stellar system near the Milky Way’s center appears to contain up to four generations of stars, giving astronomers a rare surviving record from the galaxy’s early formation.…

NASA is preparing a rare orbital rescue through its Swift Boost mission, sending a robotic spacecraft to raise the altitude of the Neil Gehrels Swift Observatory before atmospheric drag pulls it too low. The plan centers on LINK, a servicing satellite built by Katalyst Space, which is scheduled to launch no earlier than Tuesday, June…
A study in Nature Astronomy reports a roughly 14-kilometer-thick layer deep in the Martian crust that may be the leftover base of a vast ancient magma system. Using seismic waves recorded by NASA’s InSight lander, the research team found evidence that Mars once stored, sorted and modified molten rock through a deep crustal plumbing network.…
A study in Nature Astronomy has linked a high-energy neutrino detected by IceCube to a dust-hidden galaxy about 11 billion light-years away. The galaxy, formally known as JCMT0402−0424 and nicknamed Shadow Blaster, gives astronomers a striking new candidate for one of the Universe’s hardest-to-trace signals. The finding matters because high-energy neutrinos are cosmic messengers that…
