Magnetic Barriers Might Explain Mysterious Hot Jupiters

by Jonathan O’Callaghan 3 June 20243 June 2024

Hot Jupiters might end up very close to stars because a magnetic field halts their progress—and future observations could confirm the idea.

The End of the Eclipse

Damond Benningfield, Science Writer by Damond Benningfield 26 March 202412 February 2025

Scientists are studying how the Earth–Moon distance has changed over time, and what effect that change might have had on our planet. Future changes will extinguish total solar eclipses entirely.
