INBOX ASTRONOMY NASA’s Webb Examines Cranium Nebula Release date: Wednesday, February 25, 2026 10:00:00 AM Eastern Standard Time The telescope used two instruments to capture mind-bending new views of the little-known nebula PMR 1. Astronomers are losing their heads over the latest images from NASA’s James Webb Space Telescope, which bear a striking resemblance to a transparent cosmic cranium, revealing the “brain” inside. The nebula, officially named PMR 1, is being created by an aging star that is expelli ...Continue Reading

INBOX ASTRONOMY NASA’s Webb Telescope Locates Former Star That Exploded as Supernova Release date: Monday, February 23, 2026 10:00:00 AM Eastern Standard Time Webb shows star was surrounded by a vast shell of carbon-rich dust. What types of stars explode as supernovas? Usually, we have to try to answer that question after the fact. Astronomers will study the composition and amount of gas expelled in the explosion to gain clues about the former star. But on rare occasions, astronomers are able to identify th ...Continue Reading
