A new theory is challenging everything we know about Sagittarius A*, the supermassive object at the heart of our galaxy. For decades, physicists have been certain it’s a black hole. They have observed its effects and even built a planet-sized telescope just to image it. But now, a mind-bending theory is turning our understanding upside down. What if Sagittarius A* isn’t a black hole at all, but something far stranger?

Something Came Out of 3I/ATLAS

Fri, 19 Jun 2026 09:10:23 +0000

3I/ATLAS will soon be gone forever, and it just did the strangest thing yet.

▀▀▀▀▀▀

3I/ATLAS is leaving the Solar System. Having flown past Jupiter and now rapidly receding into deep space, the interstellar object has scientists scrambling to make final observations before it is out of reach forever. In our fourth and final video about 3I/ATLAS, we're digging into the final images we might ever see of it, the latest discoveries from its loop around our Sun, and the mysterious explosion that could change everything we know.

The 500-Million-Year-Old Evidence That Earth Had Rings

Fri, 19 Jun 2026 09:10:23 +0000

Did Earth have rings like Saturn?

▀▀▀▀▀▀

Saturn’s giant rings make it the most easily recognisable planet in the solar system. But what if Earth had a ring system of its own? The answer might surprise you. New evidence suggests that half a billion years ago, Earth actually did have its own rings encircling the planet. What would they have looked like from the ground? And could Earth ever develop a spectacular set of rings again in the future?

NASA Found Evidence of Water All Over Mars, and It's a Big Deal

Fri, 19 Jun 2026 09:10:23 +0000

This Astrum supercut explores the search for water on Mars. Recent discoveries have allowed scientists to build up a picture of an ancient world shaped by rivers, lakes, oceans, and rain. But what has each rover actually found? And what does it mean for future exploration and the search for life?

To those returning and new to the channel: This video is a supercut of Astrum’s best videos about water on Mars, plus new and updated content. We’ve edited this into a new seamless video, all remastered in 4K resolution.

JWST Spotted Mysterious Red Dots at the Edge of the Universe

Fri, 19 Jun 2026 09:10:23 +0000

Mysterious red dots have been spotted all over the early Universe.
JMP is an interactive statistical discovery software for scientists and engineers to explore data visually, uncover meaningful patterns, and make confident data-driven decisions. Check out http://jmp.com/astrum for your free trial.

▀▀▀▀▀▀

A series of little red dots is shattering our understanding of how the Universe began. These bizarre, glowing dots are far too massive and bright for their age, suggesting they could be a brand new type of cosmic object. Join us as we investigate the mind-boggling theories… Could these red dots be black hole stars?

Saturn's Death Star Moon Has a Surprising Secret

We used to think Mimas was a dead world, famous only for the massive crater that gives the moon an uncanny resemblance to the Death Star. But in 2024, scientists discovered a secret hidden beneath its battered shell: a vast, liquid ocean we didn’t know existed.

Why You Should Pay Attention to TRAPPIST-1

Fri, 19 Jun 2026 09:10:22 +0000

Could there be life in the TRAPPIST-1 system?
Want to learn coding in a way that actually feels fun? Check out Coddy here: https://link.coddy.tech/bvMS/im?af_sub1=Astrum and start building your streak with bite-sized coding lessons, quizzes, and projects.

▀▀▀▀▀▀

This Astrum supercut explores TRAPPIST-1. This star system is home to our best candidates for Earth 2.0, containing seven Earth-like exoplanets orbiting within the star’s habitable zone. What have we discovered on each of the planets so far? Are any of them actually habitable? Join us to find out why scientists think this system is our best chance at finding life beyond Earth.

To those returning and new to the channel: This video is a supercut of Astrum’s best TRAPPIST-1 videos, plus new and updated content. We’ve edited this into a new seamless video, remastered in 4K resolution, and re-recorded older voiceover to match the quality of recent content.

We Found New Evidence of Life on Saturn's Moon Enceladus

Fri, 19 Jun 2026 09:10:22 +0000

Could there really be life on Enceladus?

Enceladus’ ocean is far more active than we thought. New images from the James Webb Space Telescope revealed the largest plume ever seen erupting from the tiny moon’s frozen surface. Deep diving into Cassini data, scientists have uncovered the chemistry hiding in the depths of the subsurface ocean… and it’s more complex and shocking than anyone imagined. Is this small moon the most likely home for life beyond Earth?

How did Artemis II finally get off the ground?

At the time of making this video, the spacecraft is now on its way to swing around the Moon; the first crewed mission to do so in over 50 years. But why has it been so hard to get the mission off the ground? In this video, we’ll find out why Artemis got stuck on the launchpad since February, and what it’s going to do next.

Two Huge Black Holes Just Crashed Into Each Other

Fri, 19 Jun 2026 09:10:21 +0000

Scientists detected a black hole signal that should be impossible.

In 2023, LIGO spotted a record-breaking signal that was initially dismissed as a glitch… until a second detector confirmed it. It wasn't just a regular black hole merger, like LIGO has seen before. This was a crash between two black holes that, according to our models, shouldn't exist at all.

We've Never Seen a Supernova Explode Until Now

Fri, 19 Jun 2026 09:10:21 +0000

We’ve finally seen a star exploding in real time.
If you love learning about science as much as I do, head to http://brilliant.org/astrum to learn for free for a full 30 days. You'll also receive 20% off a premium annual subscription, giving you unlimited access to everything on Brilliant.

▀▀▀▀▀▀

For the first time, we have a front-row seat to one of the most violent events in the universe: a supernova. But there’s a catch - the shape of the explosion was not what we expected. In this video, we investigate the inner workings of the blast to find out what’s really going on inside.
