Travelers in the Night Eps. 351E & 352E: Active Asteroid & Flying Mud Balls
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 & September 2025. Today's 2 topics: - When it was first spotted by astronomers at Space Watch on Kitt Peak, 2008 GO98 appeared to be one of many outer main belt asteroids moving through the night sky. 9 years later when my Catalina Sky Survey teammate Greg Leonard observed it with our 60 inch telescope on Mt. Lemmon it had a coma and a tail like a comet. Active asteroids like 2008 GO98 have asteroid orbits...

EVSN - Active Black Hole’s Surge in Brightness Due to Magnetic Flip
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.

Guide To Space - What Will It Take To Stay Healthy In Space? Practical Artificial Gravity
The 365 Days of Astronomy
From Mar 14, 2018. One of the biggest problems of spaceflight is the total lack of gravity. Here are some proposals that could generate artificial gravity through rotating spacecraft.

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...

EVSN - JWST's Picture Album of Baby Stars, Planets, Moons & More
The 365 Days of Astronomy
From November 5, 2025. In this episode, we look at some of our latest discoveries about the formation of star systems, including planets and moons, and the growth of black holes. We also take a closer look at our brightening skies, and the missions set to make things worse. We also cover the latest tales from the launch pad.

From August & September 2025.
Today's 2 topics:
- When it was first spotted by astronomers at Space Watch on Kitt Peak, 2008 GO98 appeared to be one of many outer main belt asteroids moving through the night sky. 9 years later when my Catalina Sky Survey teammate Greg Leonard observed it with our 60 inch telescope on Mt. Lemmon it had a coma and a tail like a comet. Active asteroids like 2008 GO98 have asteroid orbits but sometimes show cometary activity which could be caused by a collision with another object and/or by thermal fracturing and ice sublimation caused by the slight warming they obtain from sunlight.
- 75% of asteroid hunter's discoveries are called C type asteroids. They are dark, have a high abundance of carbon, consist of clay and silicate rocks, and may have a composition which is up to 22% water. Recently Dr. Phillip A. Bland of Curtin University in Australia and Dr. Bryan Travis of the Planetary Science Institute in Tucson, Arizona published an article in the on line journal Science Advances describing their numerical simulations of the evolution of the progenitors of the C type asteroids.
