The 365 Days of Astronomy

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 June 2026.
Today's 2 topics:
- My team the Catalina Sky Survey has pioneered searching for asteroids coming from the direction of the dark side of the Moon. 
 
- On St. Patrick's day 2026 a fireball meteor brighter than the full moon streaked across the daytime sky. The American Meteor Society received 223 eyewitness reports from observers in 15 states, the District of Columbia, and Ontario, Canada as well as 5 videos and 6 photos. NASA reported that the incoming object was approximately 6 feet in diameter, weighed about 7 tons, released the energy of 250 tons of TNT, created a sonic boom heard over a wide area, and rained bits of itself onto the ground in Medina county Ohio.

In the outer reaches of our Solar System, beyond the orbit of Pluto, NSF–DOE Vera C. Rubin Observatory has spotted 2026 ED138 — a large, bright trans-Neptunian object that scientists have identified as a dwarf planet candidate. If confirmed, ED138 would be among the largest dwarf planets ever discovered in this region of the Solar System.
In this podcast, Dr. Matt Holman discusses the discovery of this interesting object, what we currently know about it and the future of dwarf planet science with the Rubin Observatorty.

From December 13, 2019.
We've had an amazing trip, even if we didn't get to see rocket launches. But we can't help but to comment on science when we see it mishandled, and this time it was a ride at Disney's Animal Kingdom. There was a ride that took us on a "time machine" to catch a dinosaur, right before the meteor impact that we believe caused the major extinction event. Let's just say "That's not how it works - that's not how any of this works," once again.

In 1859, the Sun gave off the most powerful solar flare on record. A blast of radiation and particles so strong it fried electrical wires and set telegraph towers on fire. What would happen if a solar storm of this magnitude happened today? It would be a very bad day indeed!
