Alien-hunting telescope “Breakthrough Listen” detected a faint pulsing signal… but then it disappeared. Now they’re searching the centre of our galaxy for the source. Is this one of the thousands of missing pulsars scientists predicted should exist, but can’t seem to find? And could this discovery finally prove general relativity?▀▀▀▀▀▀

In 2011, a magnitude 9.1 earthquake struck off the coast of Japan, unleashing a tsunami up to 40m high - far larger than any model had predicted. It caused untold damages including the Fukushima Daiichi nuclear disaster. For more than a decade, scientists have been trying to explain why. But now, thanks to a record-breaking ocean drilling expedition and a new study published in Science in December 2025, we may finally have the answer…This is the real geological story of why the 2011 tsunami was so devastating - and what it means for predicting the next one.▀▀▀▀▀▀

In this Astrum compilation, we’re exploring Pluto, our solar system’s most loved dwarf planet. We’ll dig into the most important discoveries we've made - from stunning high-resolution images of Pluto’s surface, to mysteries hiding deep inside its core, and the violent origins of its twin moon, Charon. Plus, we'll investigate the burning question: will Pluto’s planetary status ever be restored? ▀▀▀▀▀▀Spend less time searching and more time with the people who matter most.

Decades after the Cassini-Huygens touched down on Titan, cutting-edge observations from the James Webb Space Telescope are revealing surreal phenomena on this giant Saturnian moon. From monster slow-motion waves in its methane lakes, to unknown organic compounds that defy our knowledge of organic chemistry, there is so much more to understand about this world - and in 2030, we’re going back… ▀▀▀▀▀▀

In all of space, nothing is more mind-meltingly strange than a black hole. These cosmic monsters are places where space becomes time, time becomes space, and the fundamental laws of physics simply cease to exist. But what if the event horizon isn't the final boundary?Way past the point of no return, deep inside spinning Kerr black holes, lies a theoretical boundary even stranger than the first: the Cauchy Horizon. Beyond this threshold, spacetime breaks down entirely, cause and effect collapse, and physics yields to pure, unpredictable madness.From the lethal trap of spaghettification to time-looping curves and infinite mass inflation, discover what happens when you attempt the ultimate one-way trip into the abyss....▀▀▀▀▀▀

Theories on how our solar system formed have been turned on their head.In this Astrum compilation, we’re delving into the world of comets. What they’re made of, where they come from and just how difficult they are to land on. From the probe that crashed into one on purpose, to another that landed on a comet that looks more like a rubber duck than a rock… and that’s before we even get started on 3I/ATLAS.▀▀▀▀▀▀

This Astrum supercut is a complete guide to the planetary enigma that is Uranus. We’ll dig into why exactly it rolls around the solar system on its side, what makes it the coldest planet on the solar system and how the remains of an ancient collision might still be buried at its heart.To those returning and new to the channel: This video is a supercut of Astrum’s best Uranus videos, plus new and updated content about the planet. We’ve edited this into a new seamless video, remastered in 4K resolution, and re-recorded the older voiceover to match the quality of the recent episodes.▀▀▀▀▀▀Whether you want to contribute to the same target or help build a wider image of the sky, you can explore active Star Party projects through the DWARFLAB app. Click the link https://bit.ly/astrum-starparty or scan the QR code to learn more, and use code ASTRUM for 5% off eligible DWARFLAB products.

We've all seen the horror movies where the dead come back to life - their minds controlled by other beings; their nervous systems hijacked by some supernatural presence.But it turns out that this isn't supernatural. In fact, it's entirely natural...Nature is filled with zombies, that take control of other unsuspecting organisms and force them to do their bidding. From mind-controlled ants to zombie snails, and even... us?▀▀▀▀▀▀
