Short Wave · Salty Clouds aren’t the only strange thing about this object in space · 26 Jun 2026 podcast
Perfect.
Yeah, stay tuned.
Our second and third topics are a lot closer to home, the exciting possibility of a sex-specific burial site of ancient human relatives, and what great apes' laughter can tell us about the evolution for human communication.
All right, Gina and Juana, we've got a lot to get into.
And whichever one this object is, we know that it's really dim and couldn't be fully studied from ground telescopes until a study out this month in the Astronomical Journal about GJ504b.
Astronomers were finally able to analyze the light using the James Webb Space Telescope, and they got some information on what chemicals are in its atmosphere.
So what can scientists say about it?
They could say something about the kind of clouds that were in the atmosphere.
So this maybe, maybe not planet.
It's about 550 degrees Fahrenheit.
That's probably how hot your oven gets at home.
And that might seem hot to us, but that's actually pretty cool for other worlds like this.
So the study modeling and this temperature all pointed towards, get this, salt clouds.
And there actually aren't a lot of objects in space like this one.
And this species, called Homo naledi, they lived a few hundred thousand years ago.
They walked upright and they had human-like hands and feet, but their brains were much smaller than those of ancient humans.
Okay, okay.
That's lead author and molecular scientist Paulessa Madupe.
She says the chances are about one in a million that all 20 would be female.
So the team thinks this could have been an intentional sex-specific burial practice.
