SEA: Space Exploration & Astronomy

I make chilled-out "info-tainment" videos on all-things space related, from the moment of the Big Bang to the end of the universe itself- and everything in between. No AI, written, recorded and produced by a real human. New episodes every Sunday!

The Final Age of the Solar System (Part 2)

SEA: Space Exploration & Astronomy ·

2026/05/10

Earth is a success story, a thriving world that has hosted life for almost 4 billion years. But, no matter how peaceful things are now, a new age is coming for the Solar System. An age of change, destruction and evolution. A place for new worlds and new stories, but one in which the Earth has no place.MUSIC:- Dreamscape - Density & Time - The Unknown - CO.AG Music - https://youtu.be/IFYTGVE1aRs- Sunrise on Mars - Audionautix- As Prevent You Do - pATCHES - At the Foot of the Sphinx - Twin Musicom

The Birth of the Solar System

SEA: Space Exploration & Astronomy ·

2026/05/03

The Solar System is vast and diverse, home to eight large planets, including one which gave rise to life. While humanity was born too late to witness the events that occurred at the birth of the Solar System first-hand, by peering into the surroundings of others stars, we are starting to piece together the events that unfolded at the birth of our own Solar System. Today, we shall explore the culmination of these decades of research, as we tell the story of the birth of the Solar System.MUSIC: - In

The James Webb Telescope (2022 Version)

SEA: Space Exploration & Astronomy ·

2026/04/26

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.

When Black Holes Collide

SEA: Space Exploration & Astronomy ·

2026/04/19

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.

Dwarf Planets: Lesser Worlds

SEA: Space Exploration & Astronomy ·

2026/04/12

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.MUSIC:- Mist - Odonis Odonis- Lucid Haze - Amulets - Shallow Depths - jAde Wii - At the Foot of the Sphinx - Twin

The Oort Cloud: The Solar System's Shell

SEA: Space Exploration & Astronomy ·

2026/04/05

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.All background songs in this video were sourced from the royalty and attribution-free YouTube Audio Library. CHAPTERS:00:00: Introduction

Moons Beyond the Solar System

SEA: Space Exploration & Astronomy ·

2026/03/29

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

Europa: A Frozen Oasis

SEA: Space Exploration & Astronomy ·

2026/03/22

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 LibraryCHAPTERS:00:00 Introduction00:58: Facts About Europa 04:22:

Corrupted Stars: Hypothetical Stars that Defy...

SEA: Space Exploration & Astronomy ·

2026/03/15

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

SEA: Space Exploration & Astronomy ·

2026/03/08

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.

The Mind-Blowing Scale of Voids & Supervoids

SEA: Space Exploration & Astronomy ·

2026/03/01

Supervoids are the enormous, empty spaces between galaxy clusters and galaxy filaments. But just because they are empty, doesn't mean they can't be filled with fascinating science! They have taught us a great deal about both galaxy structures in the early universe, and how they grow in the present. And today we'll be venturing into a few of the biggest!MUSIC: - Long Walks [Emily A Sprague] - YouTube Audio Library - Fairy Meeting [Emily A Sprague] - YouTube Audio Library - A Slow Dream

Large Quasar Groups

SEA: Space Exploration & Astronomy ·

2026/02/22

Quasars are the brightest phenomenon in the entire universe, able to outshine any type of star, and even entire galaxies containing hundreds of billions of them. They are the product of monster black holes at the centres of large galaxies, and so when we find multi-billion light year clusters of quasars dotted around the early universe, we are forced to reconsider some of our most fundamental assumptions of cosmology.BACKGROUND MUSIC:- Cylinder One - Chris Zabriskie - Descent - The Tower of Light
