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.SOUNDTRACK (In order of appearance): - Guided Meditation | Jon Presstone - A Creepy Atmospheric | Unknown, Storyblocks Media- Alkaidia Obscured Calls | Bzur - Curve | CO.AG Music (https://youtu.be/3uYCzfzmh68?si=3fRFV9NNxM7y6V3y)- Crystal Ray (Cinematic Ambient) | Park Randoux- Ethereal Light Waves | Jon Presstone - Transcendent Bliss | Jon Presstone - The Slow Passage of Time | Jon Presstone - A New Galaxy | Jayson Wayne BrownCO.AG Music's Channel: https://www.youtube.com/@co.agmusicCHAPTERS:00:00: In the Space Between Stars…02:00: Rogue Planets 07:19: Failed Stars09:26: James Webb Telescope’s JUMBO Discovery 13:31: Sedna 16:05: ETNOs19:07: Planet 9? 22:22: How was Planet 9 Lost? 25:30: The Ongoing Search for Planet 928:23: A New Candidate?

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.BACKGROUND TRACK: "Christmas Ambience" by CO.AG MusicSong: https://youtu.be/e23_O1koRiA?si=5gebdLo6tpmIQpY3Artist: https://www.youtube.com/channel/UCcavSftXHgxLBWwLDm_bNvACHAPTERS:00:00: Welcome... 01:45: Anatomy of the Sun 05:03: The Coronal Mystery 08:21: Space Weather & the Solar Cycle11:59: Geomagnetic Storms15:31: The Carrington Event18:38: A Geomagnetic Storm in 2024?22:20: Missions to Study Space Weather 25:02: The Parker Solar Probe 30:28: Parker's 2024 Mission

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.
