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...
