NASA advances its all-glass LISA telescope with final pre-flight test unit from L3Harris

NASA announced on October 8, 2026 that L3Harris Technologies will build the Engineering Test Unit of the all-glass telescope for the LISA gravitational-wave observatory, the final pre-flight step before flight hardware for a mission that will listen to the universe in frequencies no Earth-based detector can reach.

SMILE's Ultraviolet Camera Captures the Full Auroral Oval for the First Time Since 2008

NASA's October 6 Astronomy Picture of the Day features SMILE's ultraviolet video of the full northern auroral oval, first released by ESA on September 30. Here is what the footage shows, what a magnetospheric substorm actually is, and why continuous whole-oval watching matters for power grids, polar flights, GPS and aurora watchers.

Hubble image reveals NGC 4698, a Virgo Cluster galaxy whose center spins the wrong way

New Hubble observations of NGC 4698 in the Virgo Cluster show a spiral galaxy whose central stars and gas rotate perpendicular to its disk, likely the result of accreted outside gas and a past minor merger. The finding is a reminder that galaxies are not finished objects: they still grow by consuming their surroundings.

Asteroid 2026 RW1 Tested the Early-Warning Chain, but Its Ending Remains Unobserved

Survey observations became a same-day atmospheric-entry prediction within hours. The official record still stops short of confirming a fireball, surface impact or recovered material.
