Here we look at a number of interesting objects in our solar system, and missions to the less frequented places in the inner solar system like Mercury and Venus.
Julie and Jeremy chat about the history of exoplanet discovery, notable astronomers Riccardo Giacconi and Ejnar Hertzsprung, and the discovery of Triton. In the news, a rogue planet is acting like a star, old data sets are reanalysed to get new insights into Venus and Enceladus, and the Universe might not expand forever.

Join us as we discuss exploring our Solar System! Hosted by Paul Mackin and Professor Mary-Helen Armour, this week we discuss one of the most significant events in space history - landing humans on the Moon - and how we aim to achieve a repeat performance.
In this week's episode we highlight missions with milestones on this day like Mariner 4, and New Horizons. We also look at aspects of asteroids and comets in the news, now in in this day in history. Image Credit: Hubble Space Telescope Comet Team and NASA
Julie and Mary-Helen discuss Newton, Shklovsky, and Bethe - three scientists with many achievements to list. They explore how technology has evolved while talking about Roswell, a bolide captured by a weather satellite, and new frontiers being pushed by JWST. Episode image credit: NOAA-CIRA
In this episode Dr. Mary-Helen Armour and Dr. Jeremy Webb discuss the summer solstice touching on what a solstice is, and what historical significance it has in everything from time keeping, finding the size of the Earth, and how ancient monuments were aligned. In the news we touch on the early images from the Vera Rubin telescope. Image courtest NASA at https://svs.gsfc.nasa.gov/14366/
In this episode Sunna Withers and Dr. Elaina Hyde investigate some historical moons of Saturn, Pluto, and of course our own Earth's Moon as well as the latest Moon news and discoveries from JWST. Image credit: 2025 03 08 The moon through the AICO Unistellar eVscope by Nakul Sethuram

This episode touches on transits of Venus and their historical and astronomical importance. It also looks a bit at how the observations of the solstice could also be used to gain an understanding of Earth. Your hosts Prof. Mary-Helen Armour and Dr. Elaina Hyde touch on more modern history looking at lunar investigation by the Surveyor and Hayabusa2 investigation of asteroids. In the news we look at recent JWST discoveries, like one of the most distant and youngest galaxies every imaged, amazing aurora and hot exoplanets.
