EVSN - Betelgeuse: Smaller & Closer Than Previously Thought… What?
The 365 Days of Astronomy
From October 19, 2020. Hosted by: Dr. Pamela L. Gay () Today’s top story brings back our favorite red giant star, Betelgeuse. A new paper published in The Astrophysical Journal (ApJ) with lead author Dr. Meridith Joyce looks at Betelgeuse as a pulsating variable star and uses atmospheric physics to bring us new insights on what the red giant is up to. This paper combines new observations with new computer models to derive the star’s mass and size from its outward behavior in much the same way that one might derive the size of a jug based on what notes can be created by...

Deep Astronomy - The Triangulum Galaxy: The Most Distant Naked Eye Object
The 365 Days of Astronomy
Hosted by Tony Darnell. From Nov 7, 2017. Have you ever wondered what the most distant object we can see with our naked eyes is? The answer is The Triangulum Galaxy some three million light years from Earth. This galaxy, along with the Great Andromeda Galaxy will collide with our Milky Way in about four billion years. This galaxy collision will herald in a new era for our home galaxy The Milky Way. We will transform into an entirely new galaxy with billions more stars.

Cheap Astronomy - Dear CA # 139: Clearing the Neighborhood
The 365 Days of Astronomy
Saving the world on a tight budget. Hosted by Steve Nerlich. Dear Cheap Astronomy – Can we clear all the PHOs from around Earth? A key feature of Cheap Astronomy’s CSOTM (Crash Shirt On The Moon) proposal is that the most readily available source of shirt to crash are near Earth asteroids and a small number of comets. This has the double benefit of putting all the raw materials in one place, plus you are clearing out potentially hazardous objects that could collide with Earth at some time in the future. Dear Cheap Astronomy – Can we really deflect asteroids with rocket engines?...

Travelers in the Night Eps. 375 & 376: Extraterrestrial Whales & Tiny Space Rock
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 February 2026. Today's 2 topics: - In an area which is about 1/400th of the entire sky, the NASA Kepler spacecraft has discovered 30 Earth like planets which are likely to have liquid water on their surfaces orbiting distant stars. These planets are likely to represent a tiny sample of the habitable planets which exist in the Milky Way. In spite of our efforts to find them, the question remains where are the alien...

NOIRLab - The DESI Legacy Imaging Surveys
The 365 Days of Astronomy
Hosted by Rob Starks. The newest DESI Legacy Imaging Surveys map, 13 years in the making, covers three-quarters of the sky and catalogs nearly four billion objects. This treasure trove is available to all and contains stars, galaxies, supernovae, gravitational lenses, and much more. Two NSF NOIRLab facilities contributed data to the map: the U.S. National Science Foundation (NSF) Mayall telescope and the NSF Blanco telescope, equipped with the U.S. Department of Energy-fabricated DECam. In this podcast, Dr. John Moustakas discusses the surveys, the data and how it will impact future...

Guide To Space - Universe Today News: 7 Stage Journey Reveals How Falling Space Rocks Survive Air
The 365 Days of Astronomy
By - August 31, 2026. Recorded by our Editor, Richard Drumm. At least once in our lives, we’ve all seen a bright streak of light briefly blaze across the sky and have quickly referred to it as an asteroid, meteor, shooting star, comet, or some other whimsical name we’ve heard others use to describe it. For those calling it a meteor, you would be correct, but we’ll touch upon this later. The time it takes for a space rock, bolide being its scientific name, to travel through Earth's atmosphere and crash into the ground literally takes only a few seconds. But what happens to a space rock...

From January & February 2026.
Today's 2 topics:
- On Earth, human life is enabled by plants which provide us with calories, vitamins, fuel, medicines, and oxygen to breathe. In addition, recent scientific studies indicate that plant cultivation reduces anxiety and depression and has a positive influence on diabetes, heart disease, obesity, and longevity. Perhaps this is the reason that 80% of the cultivated plant species on planet Earth are not used for any food related purpose. On long duration space missions astronauts live in close quarters isolated from the natural world where the basic activities like eating, sleeping, and attending to bodily functions are difficult and stress producing.
- On it's gravitational leash, Earth's pet space rock, 2016 HO3, accompanies us at a distance of between 38 and 100 times the Moon's distance from Earth as we both travel about the Sun. As this tiny asteroid orbits the Sun it spends about half of its time inside the Earth's orbit where it moves faster and passes ahead of us and the other half of its yearly path outside of our orbit which causes it to lag behind our home planet. Since its discovery little has been known about Earth's pet space rock leaving some to speculate that perhaps it is an old rocket booster or other piece of space junk.
