Deep Astronomy - The Amazing Orion Nebula As Seen By Hubble & Spitzer Space Telescope
The 365 Days of Astronomy
From Jan 12, 2018. Hosted by Tony Darnell. Like this content? Please consider becoming a patron: On January 11, 2017 the Spitzer and Hubble Space Telescope missions released an amazing flythrough of the Orion Nebula, or M42. Never before have we had such a detailed look at this naked eye object in two wavelengths. Using actual scientific imagery and other data, combined with Hollywood techniques, a team at the Space Telescope Science Institute in Baltimore, and the Caltech/Infrared Processing and Analysis Center (IPAC) in Pasadena, California, has created the best and most...

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...

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...

From September 8, 2023.
There’s no question that humanity is making fast progress in understanding, cataloging and classifying planets around other stars. So far we’ve found over five thousand five hundred of them. But let’s face it, we really want to know, maybe more than anything else, whether these planets have any life on them and whether they are habitable for us to, maybe, live on.
Finding habitable worlds has been a driving passion since we first learned there were other planets out there, and to find them, we are going to need a dedicated instrument that does nothing else but tries to locate and characterize them.
That’s where the Habitable Worlds Observatory comes in. NASA says “HWO is a concept for a NASA flagship mission, as recommended by the 2020 Astrophysics Decadal Survey, that would pursue a breadth of astrophysics goals, including searching for and characterizing potentially habitable planets beyond our solar system.”
