  • Have We Found the Oldest Galaxy In the Universe?
    Feb 26 2026

    In this Astrum Supercut, we're heading back to the birth of the universe. With telescopes like JWST, we’re now able to peer back to the beginning of time to witness the very first galaxies ever to form. But the deeper we look, the more we find things we didn't expect. Are our models of the cosmos actually wrong?To those returning and new to the channel: This video is a Supercut of our best early universe videos, plus some new and updated discoveries. 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.

    Out in the far reaches of Saturn’s orbit lies a moon that doesn’t belong. This is Phoebe: a dark, rebel object racing against the calm flow of the Saturnian system. Join us to find out how this unlikely moon could unlock the secrets of Saturn’s violent past, and perhaps the origin of the rings themselves.▀▀▀▀▀▀

  • Have We Found The Universe's Missing Mass?
    Feb 5 2026

    Have we just found the universe's missing matter?
    Astronomers know exactly how much visible matter the entire universe should contain. The problem is, that for decades, 40% of it has been missing. Nowhere to be found. For the first time in history, we may have finally found where the missing mass of the universe has been hiding… And it’s in plain sight.▀▀▀▀▀▀
