The 365 Days of Astronomy
From May 10, 2022. A luminous black hole already classified as an active galactic nucleus brightened suddenly in recent ground and space observations, and the cause may be due to a sudden flip in the magnetic poles. Plus, community science, rockets, Ingenuity, and an interview with Dr. Cathy Weitz from Planetary Science Institute.

Astronomy Cast Ep. 771: Comet Tails
The 365 Days of Astronomy
Hosted by: Fraser Cain and Dr. Pamela L. Gay Streamed live on Nov 8, 2025. With the arrival of the comet 3I/Atlas (Asteroid Terrestrial-impact Last Alert System), the world is getting a crash course in comets, their behavior, and of course their tails. Today we’re going to talk about comets and their tails, why they exist, how they grow, why they can be different colors and how they can be sometimes point AT the Sun. Comets are one of the most animated and ephemeral targets for astronomy. From night to night they can change in shape and color, and every nuance tells us something. In...

Travelers in the Night Eps. 349E & 350E: Trappist-1 Planets & Brute
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From August 2025. Today's 2 topics: - The Trappist-1 planetary system located about 40 light years away in the constellation of Aquarius consists of a small red dwarf star and 7 Earth sized planets. By carefully studying changes in the planet's transit timings and the shape of the dip in the host star's brightness as each planet transits across it, astronomers have been able to measure the orbital period, radius, and...

Today's 2 topics:
- On consecutive nights my Catalina Sky Survey teammate Richard Kowalski discovered two very close approaching asteroids. One of Richard's discoveries, 2016 BY14 must be made out of pretty tough stuff since when it was closest to the Sun it received more than twice the solar energy which heats the surface of Mercury to 800 F. Asteroid hunter's continue to need to track 2016 BY14 to make sure that its orbit does not change to make it a threat as it passes near the paths of Mercury, Venus, Earth, our Moon, Mars, and Jupiter.
- In 2013 my Catalina Sky Survey teammate Steve Larson discovered a space rock streaking through the night sky. For the next 3 days this object was observed by telescopes in California, England, Chile, and New Mexico and given the name 2013 TX68. About 10 days after being discovered, this small asteroid became invisible to human telescopes as it moved towards the Sun with increasing amounts of its dark side facing towards us. Hopefully asteroid hunters will come across 2013 TX68 during its 2016 encounter with Earth. The data obtained will allow us to predict when and how close it will approach our to home planet in future years.
