NASA’s IMAP Mission: Mapping the Sun’s Heliosphere

Bedtime Astronomy ·

2025/10/10

In this episode, we dive into NASA’s IMAP mission—the Interstellar Mapping and Acceleration Probe—set to study the heliosphere, the magnetic bubble that shields our solar system.Led in part by University of Delaware scientist William H. Matthaeus, IMAP will orbit at Lagrange Point 1 to analyze solar wind, plasma, and magnetic fields. Joined by the Carruthers Geocorona Observatory and NOAA’s Space Weather Follow On, this mission will expand our view of how the sun interacts with interstellar

2025/10/04

New research suggests that Uranus’ moon Ariel may have once harbored a massive subsurface ocean over 100 miles deep. By analyzing fractures and ridges on its surface, scientists linked these features to tidal stresses from Ariel’s past eccentric orbit.The findings raise the possibility that Ariel—and perhaps Miranda—are twin ocean worlds, offering an exciting target for future space missions.
