The 365 Days of Astronomy

Travelers in the Night Eps. 807 & 808: Moon Orbit Crossers & Global Auroras on Mars

6 min • 10 augusti 2025

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

From July & August 2024.

Today's 2 topics:

- During a recent 60 day period of time 23 space rocks came closer to Earth than our Moon.

- When the Earth enters a stream of high speed protons and other charged particles in the solar wind or our home planet is impacted by a solar coronal mass ejection the Earth’s strong magnetic field acts a a shield. Mars on the other hand lacks an Earth-like magnetic field and thus has little protection from solar storms.
