Lost Worlds in the Dark
Laced within the cold, desolate swathes of the space between stars, lie myriad orphaned planets not tethered to a particular system. They are lost worlds floating in the dark, and there are likely tens of billions in the Milky Way galaxy alone. Today, we will journey through the galaxy in search of these lost worlds in the darkness of interstellar space, and sometimes even, intergalactic space.

The Fundamental Forces of Nature
The universe as we experience it is rendered by myriad physical processes and interactions, but they all can be boiled down to one of four fundamental forces of nature. Gravity is one of these fundamental interactions, while the visible light we observe makes up part of another. And by understanding all four, we can gage comprehensive insights into our reality, from its tiniest particles to its largest galaxies.

The Sound of Space
What is the Sound of Space? The idea that it is a silent vacuum, completely devoid of any noise, is somewhat a misconception. And though sound as humans hear it can't travel in space, there are several way in which we can extract the anthems of the cosmos. And in this video, we'll be doing just that, as we embark on a journey of Sound in Space.

Do We Live in a Multiverse?
Are we living in a multiverse? If so, where are all the other universes? Scientists and philosophers have pondered these questions for centuries, as they contemplated the possibility of parallel universes. The multiverse theory is not often discussed by cosmologists, due to its speculative and untestable nature. However, there are myriad different interpretations depicting how a multiverse might manifest, some of which we may be detectable within our own universe. So buckle up, because in this video we will be leaving the galaxy entirely, as we take on the biggest question of them all- the question of whether our universe is the only one.

The Insane Science of Neutron Stars
In the late 1960s, a series of anomalous, repeating radio sources began cropping up all over the Milky Way galaxy, and though initially speculated to be messages from aliens, we soon learned that they are Pulsars, a rapidly rotating neutron star emitting high volumes of radiation. In this video, we will revisit these extreme, dense objects, as the final gateway faced by matter before it collapses into a black hole. This is the insane science of neutron stars.

Collisions of the Early Solar System
How did Earth get its moon? Why is Mercury so close to the sun? Why does Uranus orbit on its side? The answers to all of these questions are the many collisions that ravaged the early Solar System. Each of our neighbouring worlds bears scars which echo their violent past, from the many craters of the moon's battered surface, to the sideways rings of the planet Uranus. And in this video, we will examine a number of the most significant collisions, which each played a pivotal role in building up the Solar System as we know it today.

A Glimpse of the Sun
The Sun... both the giver of life, and destroyer of worlds. Host of the eight planets, and incubator of Earth with its light and heat. Yet in spite of its brilliance, the true nature of the sun's power remains shrouded in mystery, with scientists unable to explain many of the processes playing out in its atmosphere. But in 2024, NASA will attain their closest glimpse of the sun so far, as they come just five million miles from its surface, diving into the stellar Nether Zone, to "touch" the sun itself.

Back to the Moon with Artemis
It's been more than half a century since humans last went to the Moon. But we will return before the decade is up, through NASA's revolutionary Artemis Program. But unlike its ancestral Apollo Program, Project Artemis is about more than just landing astronauts on the lunar surface. Its endgame is to enable us to stay there, and keep going back to a semi-permanent surface habitat- all in preparation for NASA's yet more ambitious, daunting endeavour of the 2030s- to reach the Red Planet, Mars.

Voyager: Beyond the Solar System (Probes Episode #3)
Of all the spacecraft to have visited other worlds, there are two which have travelled further than any other, discovering more about the Solar System than their inventors ever could have imagined. They are the legendary pair of Voyager Probes- still the only spacecraft ever to have visited the Ice Giant planets, Uranus and Neptune. The story of their 40 years in space makes up the topic of our video today- from the gas giants, to the ice worlds, and then out into the depths of interstellar space...

Race to the Terrestrial Planets (Probes Episode #1)
From studying the dusty surface of Mars, to plunging into the atmosphere of Venus, over the last 60 years, we've launched hundreds of probes into space on trajectories to visit each of the terrestrial planets. But for all the fascinating discoveries made on the way, humanity's journey towards the stars started out in a much darker place- a battlefront between the world's then two great competing superpowers. And in this first episode on my new series on probes, we will revisit this space race, and the major milestones on route to visiting each of the terrestrial planets.

The Final Age of the Solar System (Part 2)
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.

The Birth of the Solar System (Part 1)
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.

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.

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.

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.

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.

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.
