Astronomy Cast Ep. 161: Launch Facilities
The 365 Days of Astronomy
From October 26, 2009. Launching a rocket into space requires a big effort on the ground. Space agencies have built up huge infrastructures to store, prepare and launch rockets. Let’s take a look at what’s involved on the ground at a place like Cape Canaveral. What happens before, during and after a launch.

Travelers in the Night Eps. 871 & 872: New Mars Trojan & Climate Ignored
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 October 2025. Today's 2 topics: - The Lagrange point L4 is 60° ahead of Mars whereas L5 is 60° behind Mars on the red planet’s orbital path about the Sun. An object placed at either of these locations is trapped gravitationally and is likely to remain there indefinitely. The Mars L4 and L5 locations could provide a permanent place for staging and resupply missions to Mars and would give humans a different view of...

NOIR Lab - An Extremely Rare Ancient Star
The 365 Days of Astronomy
Astronomers have discovered one of the most chemically primitive stars ever identified — an ancient stellar relic that preserves the chemical imprint of the very first stars in the Universe. In this podcast, Dr. Ani Chiti discusses the discovery of this ancient star and what it tells us about star formation in the early Universe. Bios: - Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. - Dr. Anirudh Chiti is a Brinson Prize Fellow at Stanford University, interested in the formation of the first stars and galaxies,...

EVSN - Science in Pairs & Moon Plans Redux
The 365 Days of Astronomy
From April 1, 2026. No foolin’! Once again, we’re going to attempt to get you up to date with what is going down at NASA. In addition to NASA updates, we have stories of science that comes in twos. From 2 planets forming in a disk to 2 stars coming together to shine brightly, to two asteroids that together orbit the Sun a bit faster, to two planets that collided, … it is a week for pairs. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs. Just visit: and donate as much as you can! Share the podcast with your friends...

UNAWE Space Scoop - A Rule-Breaking Supermassive Black Hole
The 365 Days of Astronomy
Astronomers have spotted a supermassive black hole, or SMBH, that is breaking all the rules! Well, one rule anyway. It’s called eROSITA Final Equatorial Depth Survey, or eFEDS, J084222.9+001000. Whew! It is also called ID830, don’t ask me why, so that’s what I’ll call it. Way easier! Anyway… Most galaxies have a supermassive black hole at their center. They grow by sucking down clouds of gas & dust nearby - like a powerful vacuum cleaner in space. As the black hole, uh, eats, the gas swirls inward and heats up the surroundings, making it ‘glow’ in all kinds of...

Astronomy Cast Ep. 789: What Happens When a Planet's Star Dies
The 365 Days of Astronomy
Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Streamed live on Mar 30, 2026. A star like the Sun only lasts about 10 billion years and it becomes a red giant and finally a white dwarf. This is catastrophic for some of the planets, consumed by the expanding red giant star. But most survive. What happens next in the long, slow cooling to the background temperature of the Universe? This show is supported through people like you on Patreon.com/AstronomyCast In this episode, we'd like to thank: Burry Gowen, Eric Lee, Jeanette Wink, Michael Purcell, Andrew Poelstra, David, David...

Travelers in the Night Eps. 869 & 870: Taurid Resonant Swarm & Satellite Ashes
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 October 2025. Today's 2 topics: - The planets, millions of asteroids, tens of thousands of comets, distant icy worlds, and countless other bits and pieces of material orbit the Sun. A group of such co-orbiting objects is called the Taurid complex or swarm. It consists of Comet 2P/Enke, a number of near Earth asteroids, and the meteor stream which produces the Taurid meteor shower every October and November. - 50...

From Jan 6, 2019.
The distances between stars are so vast, it’s hard to wrap your mind around it. Even our far flung Voyagers have barely reached interstellar space, and would take tens of thousands of years to get to even the nearest star.
But scientists and engineers are considering what it would actually take to send a spacecraft to another star. It’s called Project Dragonfly, and would use existing or near future technologies to send a 3,000 kg spacecraft to Alpha Centauri within 100 years.
