Cheap Astronomy - Dear CA 131: What’s The Point?
The 365 Days of Astronomy
Hosted by Steve Nerlich. Cheap Astronomy asks what's the point and then gets some sunshine. Dear Cheap Astronomy – Did the Universe start from a single point? This hypothetical concept is commonly stated in pop science blogs and we are guilty of doing the same here at Cheap Astronomy. However, it’s not necessarily correct. As with most things relating to the Universe, all we can really talk about is the observable Universe. All evidence available does suggest that it emerged from a point source 13.8 billion years ago, but if the actual Universe is bigger than the observable Universe –...

Astronomy Cast Ep. 786: Wolf-Rayet Stars
The 365 Days of Astronomy
Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Streamed live on Mar 9, 2026. You think the Sun is a terrifying ball of fire and fury? Wait until you learn about today’s topic: Wolf-Rayet stars! These are massive, dying stars hurling their outer layers out into space before detonating as supernovae. Big stars live brief lives, and Wolf-Rayet stars are the punctuation mark we see before things go supernova.

Travelers in the Night Eps. 863 & 864: Space Elevator & Lunar Debris
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: - In a recent study Dr. Lynnane George and her co-authors investigate Space Elevator technology to remove materials from Ceres and deliver them to orbital depots around the solar system. The tiny gravity of Ceres, nano-fiber technology, and different water propulsion systems are utilized by Dr. George and her team to construct theoretically possible systems which would extract raw...

NOIRLab - Results From Six Years of the Dark Energy Survey
The 365 Days of Astronomy
The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the Universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at CTIO, a Program of NSF NOIRLab. Their completed analysis combines all six years of data for the first time and yields constraints on the Universe's expansion history that are twice as tight as past analyses. In this podcast, Dr. Yuanyuan Zhang discusses the Dark Energy Survey results and how they inform the next steps in dark...

EVSN - Climate Change Melts Glaciers, Greens the Arctic
The 365 Days of Astronomy
From Sep 9, 2022. As global temperatures rise, Earth observations show that glaciers are retreating and ice sheets are melting everywhere from Greenland to Antarctica while regions of the Arctic are getting greener. Plus, collaborations lead to new Mars and exoplanet discoveries, several rockets launched, and this week’s What’s Up involves Dr. Brian May of Queen.

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.”
