  1. The James Webb Telescope (2022 Version)

    The James Webb Telescope (2022 Version)

    On December 25th, 2021, NASA's most sophisticated, ground-breaking and expensive observatory ever blasted off from the Earth. The James Webb Telescope is an infrared observatory, capable of looking back all the way to the universe's first light. In this video, we will explore how this initiative came to be, and what the future holds in this exciting new age of astronomy.

  2. When Black Holes Collide

    When Black Holes Collide

    Black holes are fascinating in so many ways- especially when you put two of them together. Their resonance and orbit physically ripples space itself, emitting waves that can travel through space for billions of years. Since 2016, we have been able to detect these gravitational wave events, and earlier this month, we detected a record-breaking one.

  3. Dwarf Planets: Lesser Worlds

    Dwarf Planets: Lesser Worlds

    The Solar System is home to eight principal planets, but this is far from the full picture. Hidden beyond the orbit of Neptune are dozens of small, icy worlds, known as Dwarf Planets, or Minor Planets! The best example is Pluto, but there are dozens more orbiting within the same band of material in the outer Solar System. Today, we will visit these frozen, far out worlds first hand.

    The Oort Cloud: The Solar System's Shell

    What lies at the edge of the Solar System? Far beyond the orbit of Neptune and the Kuiper Belt, deep into interstellar space, we find a vast, thick shell of icy space debris. We have never seen it directly, but we know it exists- because it is the source of the most distant comets that we see entering the Solar System. So why is it there? Today we'll find out.

  5. Moons Beyond the Solar System

    Moons Beyond the Solar System

    Most large planets have moons. We have discovered almost 200 in our Solar System alone, and so we expect that the Milky Way is teeming with many more- perhaps even outnumbering planets and stars. With so many moons, it adds a plethora of additional holdouts in the galaxy capable of supporting life, and thus they are tantalising targets for scientists. However, extra-Solar moons are so insanely distant and dark against the backdrop of space, that them is a tremendous challenge. In this episode, we will cover its story so far.

  6. Europa: A Frozen Oasis

    MAR 22

    Europa: A Frozen Oasis

    Europa is a fascinating moon, which is thought to be hiding a global ocean below its frozen surface. This makes it a hotspot for research and missions, with the ultimate goal being to identify an independent life source. In this video, we will go over this iconic satellite of Jupiter by the numbers, as we blow its perplexing mysteries wide open. All background music came from the Royalty-Free & Attribution-Free YouTube Audio Library CHAPTERS: 00:00 Introduction 00:58: Facts About Europa  04:22: Europa’s Ice Sheet 06:52: Missions to Europa 09:29: The Subsurface Ocean 11:19: Tidal Heating  13:44: Europa's Prospects for Life  18:15: Future Missions to Europa

    Corrupted Stars: Hypothetical Stars that Defy Explanation

    Not every star in the universe can be seen shining brightly in the night sky. There are dozens of types of fascinating hypothetical stars, which are characterised by their extreme behaviour. Today, we will be taking a look at a few of these corrupted stars, from the start of the universe right up until the end.

    Ghost Galaxies

    Not every galaxy is a fully formed spiral or elliptical galaxy. Some are much smaller, and orbit larger galaxies as well as each other, like ghosts. Today, we will examine these ghost galaxies- the satellites of the Milky Way and Andromeda.
