Actual Astronomy - 12 Months of Messier
The 365 Days of Astronomy
Episode 531. Just a reminder for people to write in with their questions for David Nagler. Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan who enjoy teaching astronomy classes and showing the public views through their telescopes. Some binocular astronomy targets: - M40 - 9.6 Magnitude 1.7’ This is a pair of faint stars located in Ursa Major. They are a tough find in binoculars, and you will be challenged to split them with binoculars. In telescopes, they appear to be an identical pair of stars and easy to split even at low power. - M108 -...

EVSN - Supervolcanoes: Erupt, Refill, Repeat
The 365 Days of Astronomy
From Wednesday, April 15, 2026. This week, in the first of our new shorter and more frequent episodes, we are going to take a look at the interplay of plate tectonics, geology, climate, and life. Specifically, we’re looking at the interplay between super volcanoes and us! Did you know Naples is on a supervolcano? Also, in this episode: human sperm get lost in space.

Guide To Space - Bringing Mars To Earth
The 365 Days of Astronomy
The Plans For a Mars Sample Return Mission. Hosted by Fraser Cain. From Aug 28, 2019. One of the great accomplishments of the Apollo missions was to bring home hundreds of kilograms of lunar rock. Suddenly, geologists had a lifetime’s worth of lunar samples captured from several different spots across the Moon. These rocks and dust have been under continuous analysis since the Apollo 11 astronauts came home over 50 years ago. And they’re still making discoveries. Scientists have samples of the Sun’s solar wind, particles from a comet’s tail, a few grams from an asteroid, with...

Cheap Astronomy - Dear CA # 133: Why It’s Always C
The 365 Days of Astronomy
Cheap Astronomy investigates why light moves at light speed in a vacuum. Hosted by Steve Nerlich. Shining a light! Dear Cheap Astronomy – Why does a photon travel at speed c, part1 It may sound a bit strange to ask why light travels at the speed of light, but that’s because c isn’t really the speed of light – it’s really a measure of the relationship between distance (or space) and time. It's become customary to call c the speed of light, but in reality light moves at different and slower speeds through air, water or glass, it only moves at c in a vacuum. Dear Cheap Astronomy...

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.

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...
info_outlineHosted by Dr. Jacinta Delhaize, Dr. Tshiamiso Makwela, Dr. Daniel Cunnama & François Campher
With Tumelo Mangena, Leyya Stockenstroom and Ndivhuwo Netshiavha.
In this episode, we hear from three postgraduate astronomy students from the University of Cape Town about their worldly adventures during a research trip to the University of Oxford in the UK!
PhD student Tumelo Mangena and Masters students Leyya Stockenstroom and Ndivhuwo Netshiavha are part of the RADHIANCE research group led by our very own Jacinta Delhaize! They use world-leading telescopes, like South Africa’s MeerKAT, to examine the light from distant galaxies to try and understand why they have mysteriously changed and evolved over the history of the Universe. Their team name, RADHIANCE, stands for “Radio-Based Analysis and Detection of HI, AGN, star-formatioN, and their Cosmic Evolution” – and they even have a cute logo!
