Turns out, planets can form their own 'solar systems', just like stars. ##space #universe #astronomy

[00:00:00]Astronomers monitoring COW 1107 noticed something was happening. The planet was suddenly devouring material at 6 billion tons per second. Rogue planets, they're cosmic nomads drifting through interstellar space with no star to call home. Maybe they never orbited a star to begin with. Maybe they formed in isolation, collapsing directly from clouds of gas and dust just like stars do, only on a much smaller scale. COW 1107 is suggesting that at least some rogue planets, especially the massive ones, might not be ejected planets at all.

[00:00:37]They might form through the exact [music] same process as stars, just on a smaller scale. This rogue world is teaching us some fundamental lessons about the cosmos. First, it's forcing us to acknowledge that the neat categories we've created for celestial objects, planet versus star, formed in place versus ejected, these categories might be too rigid. Nature doesn't care about our labels. Objects exist on continuums, and formation processes blend together in ways we're only beginning to understand. Second, it's expanding where we think planet formation can happen.

[00:01:10]We've always assumed planets form in protoplanetary disks around stars, protected and nurtured in that stellar environment. But the rogue planet is showing us that planetary mass objects can form, grow, and evolve in complete isolation in the vast darkness between stars. That opens up entirely new real estate for planet formation across the galaxy. Third, it raises the possibility that there are many more objects like this out there that we simply haven't detected yet. Rogue planets in active accretion phases might be far more common than we realized.

And finally, on a more philosophical level, it's a reminder of just how diverse the universe really is.

[00:02:08]From scorching hot Jupiters orbiting dangerously close to their stars to frozen ice worlds in the outer reaches of [music] planetary systems to rogue planets drifting alone and feeding on cosmic material. The variety of worlds out there is staggering. Our solar [music] system, orderly and predictable as it seems, is just one tiny example of what's possible.

[00:02:28]>> [music] >> Here's the question I want to leave you with. Is K2-1107 a rare cosmic oddity, a one-in-a-billion fluke that we just happened to catch at the right moment, or is it revealing a hidden side of planet formation that's been happening all along, countless times across the galaxy, just beyond our ability to see it? Drop your thoughts in the comments below. I genuinely want to know what you think about this.
