What is the largest star, and where can it be found? For a few years now, it has been known as Stephenson 2-18, often claimed to boast a diameter more than 2,100 times our sun’s. But is this estimate really reliable? And if not, then what other giant stars may be lurking out there? These are the questions we will be aiming to answer as we wind back the clock in search of the real “largest star”.

Notas del episodio
Far beyond the reaches of the four rocky planets, we find our Solar System's showpiece worlds- the two gas giants, Jupiter and Saturn. As the two largest planets, they both make tantalising targets for probes exploring the planetary neighbourhood, but both lie significantly further from the sun than the Earth and its terrestrial neighbours. But early in the 1970s, the technology for deep space voyages was primed, and missions to both Jupiter and Saturn ensued. Those missions make up the topic of our video today, in this second episode of our trilogy of Probes that Studied the Solar System.

In 2012, the world’s most advanced science experiment uncovered the signature of the Higgs Boson, the so-called “God Particle” which gives particles their masses. The Higgs was the last of the Standard Model's particles to be verified experimentally. But far from closing the case, it instead opened a new frontier in physics that today embodies everything we still don’t know about nature’s smallest scales. And so in this video, we will wind back the clock more than half a century, to unravel the history and mysteries of the elusive Higgs Boson.

Why does the universe choose life over silence? Why has its once inanimate matter and energy come alive on planet Earth? Is it chance? Fate? Or even, by design? It is this profound question that has plagued our conscious minds since the time of our earliest ancestors, and it is going to be the topic of our video today.
This video is my oldest idea, and I was planning for it as early as 2021. A massive thank you to the artist Semiquaver for composing the soundtrack that brought this vision to life.
SOUNDTRACK:
The soundtrack for this video was crafted by Semiquaver, an ambient music and soundscape artist who I'd been following for a while, and knew he was perfect for the job.
His channel can be found here: @semiquaver16th , where he regularly releases new soundscapes and compositions.
The full, 37 minute track will be available to listen to here: https://youtu.be/WQQhwggE6Bo

Can we ever turn back the clock? On Earth, Time is rigid and immovable, but in space, it's practically the opposite. Out in the cosmos, time is another dimension alongside the three of space- but unlike in 3D space, there is only one way we seem to be able to move through time. The cause of this directionality, and so-called "Arrow of Time" through the cosmos, makes up the topic of our video today- the second part in a double header on the mysterious workings of Time.
SOUNDTRACK:
The first and last tracks in this video were composed by Semiquaver, an ambient soundscape music artist. He and I will be working on an original piece specially for the soundtrack to my final video of the year, so go and check him out before then: @semiquaver16th

Tick. Tock. It's a sound you probably hear several times a day. Time dominates virtually every aspect of our lives, attuned to the rigid, unflinching regularity of Hours, Minutes and Seconds. The question how did our ancient ancestors figure out these units? Who came up with the concepts of timekeeping, like Minutes and Seconds, and why are there 60 of them, and not say, 100? The answers to such questions make up the topic of our video today- the first in a two-part series on the mysterious workings of Time.

Aliens. They already roam this planet, but not on its surface or in the skies. Rather, they lie at the crushing depths of the vast, sprawling oceans. And so in this episode, we'll be swapping the familiar frontier of space for that of the deep ocean, as we plunge into the abyss in search of Leviathans- massive, monstrous marine specimens that have stalked the high seas for almost half a billion years.

On the dark, secluded underside of our planet, we find its most alien continent, Antarctica. A frozen desert larger than Europe, lying atop a sheet containing more than 90% of the world’s ice. But buried beneath this frosty surface, lie fossils and relics from an age where Antarctica was wildly different- covered not by ice, but by forests of trees.

Notas del episodio
Long ago, the Earth's seven continents were assembled in a giant, sprawling supercontinent known as Pangea. You may've heard of it, but what is often less talked about is what came before. Our planet's current continental chunks have been smashing together and separating for over four billion years, and there have been more than a few "supercontinents" during that time. It is those lost lands that take the stage in this video, as we wind the clock back to the age of the Supercontinents before Pangea.

As rich and life-supporting as the Earth is today, it was once nothing more than a column of dust, dancing in a scorched cyclone of gas. And just how we as humans managed to emerge from this ancient dust makes up the topic of this video today. So join us, as we wind the cosmic clock backwards almost five billion years, from you and I in the present, all the way back to the birth of the solar System, back to when Earth was nothing more than a burning, barren wasteland.

Do we live in a cosmic void? It might sound like an odd question, but it’s something scientists have debated for decades. Does the Milky Way exist in a region of low cosmic density which is warping our view of the local universe as a result? The answer goes far deeper than you probably realise- and it’s just one of the many perplexing mysteries we’ll be diving into during this video, where voids and supervoids take centre stage.

Lying at the cores of most large galaxies, do we find the “largest” type of object in the universe- a supermassive “engine” black hole. They almost always have masses many millions of times that of the sun, while the biggest grow to tens of billions. Exactly what was responsible for seeding these great engines, and building up their immense sizes, is a challenge only the James Webb Telescope can rise to.

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 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.

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.

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.

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.

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.

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.

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.

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...

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.

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 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.

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.

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.

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.

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.
