Juno Snaps Rare Close-Up of Jupiter’s Shadowy Moon Thebe
NASA’s Juno spacecraft captured a record‑close view of Jupiter’s inner moon Thebe on May 1, 2026, imaging the irregular satellite from roughly 5,000 km away. Thebe, a 49‑km‑radius body orbiting 222,000 km from Jupiter, is heavily cratered and the primary source of dust for the planet’s faint gossamer ring. The image was taken with Juno’s Stellar Reference Unit, a navigation camera repurposed for low‑light science. The flyby provides the sharpest surface detail since Voyager 1’s 1979 encounter, revealing features such as the prominent Zethus crater and surface albedo variations.
Rethinking the Cambrian Explosion: Before Shells and Limbs, There Was the Brain
A new "Brain‑First" hypothesis argues that the Cambrian Explosion was driven primarily by the early evolution of complex nervous systems rather than shells or limbs. Professor Ariel Chipman suggests that rising ecological competition forced animals to develop regionalized brains, which...
