Jupiter-sized "planets" free-floating in space, unconnected to any star, have been spotted by the James Webb Space Telescope (JWST).
What's intriguing about the discovery is that these objects appear to be moving in pairs. Astronomers are currently struggling to explain them.
The telescope observed about 40 pairs in a fabulously detailed new survey of the famous Orion Nebula.
They've been nicknamed Jupiter Mass Binary Objects, or "JuMBOs" for short.

Couldnt they just be free floaters that manage to get pulled into each others gravity?

They even caught the disks of gas and dust around new stars where planets are formed. Like holy shit.

Two jupiter-sized planets around a star could plausibly eject each-other, via weird gravity stuff.

Let's just hope they don't notice us looking at them.

Could they be brown dwarfs?

That's my thinking.

I wonder what direction they are heading in. My flights in Elite Dangerous tells me they are close but far enough away to not be a huge danger. Most of stars go with the "flow". There are some remnant dwarf galaxies that the Milky Way galaxy have absorbed. For instance theres a line of stars above the plane that were just that.

Incredible telescope! It has changed what we already know. We have found galaxies father than 13.8B light years.

If I were asked to make up an explanation, I'd guess that the matter floating around was spread out enough that it gravitated to two points and the planets then became gravitationally locked to each other.

I don't think they would ever crash into earth. If they get too close to any star on their journey, they should get absorbed into that solar system. It would maybe fuck up our solar system to suddenly have a new planet. but the chances of our star being the one it comes to is astronomically low

Also, these things would take so long to get near us that none of us alive today will still be so.

Too small to fit the standard stellar formation theory. Brown dwarves start at 13 times the mass of Jupiter.

Just two planets floating without a star. Nothing wrong with that.

Someone had fun with that.

Anyway, I read somewhere, of dubious source, that some scientists think rogue planets like these JuMBOs outnumber stars in the galaxy.

Rogue planets are pretty common, although finding that many binary systems of them is interesting.

If they're jupiter-sized, they're probably just caught in each other's orbits. Probably a neat site tho if you were on one looking at the other.

What would be really interesting is if we found that life can exist on a rogue planet. That would be really strange

It's theoretical at this point but there's no reason life can't exist under an icecap on a rogue version of the Pluto-Charon pair. Or something even bigger, like a Saturn-Titan equivalent ejected from a star system. Fossil heat, radioactive decay, and tidal heating could keep a liquid ocean viable for a couple billion years, long enough for even primitive multicellular life to evolve.

Given the prevalence of ice ball planets and moons with those types of conditions, that is probably the most common habitable environment in existence.

Yeah, extremophile archaea could live on the surface or underground on all sorts of planets. It would just need to get there.
