Imagine a planet the size of Jupiter…
that you could technically squish in your hand.
Lighter than cotton candy.
Fluffier than a blob of shaving foam fresh from the can.
That's not sci-fi.
That's the real headline from astronomers this week. 🪐
A team led by Oxford's George Dransfield just unveiled two new exoplanets orbiting a Sun-like star 1,100 light-years away in the southern constellation Volans (yes, the flying fish).
They're the biggest, puffiest worlds ever found.
And the numbers are absurd.
Here's the wild part.
According to planet-formation theory, these things shouldn't really exist.
They're huge.
They're feather-light.
And they sit in a weird sweet spot scientists are still trying to explain.
The best guess so far?
They formed in a baby star's disk that was unusually gas-rich and dust-poor — basically inflating like cosmic balloons before the universe could tell them to behave.
Some researchers also suspect super-puffs are just young. Puffy in their teenage years. Destined to shrink as they age.
A planetary glow-up, basically.
Dransfield says if you could float above one of these worlds, the view would probably glow white or blue — depending on whether the skies were cloudy that day.
No solid ground.
No crunchy surface.
Just endless, drifting, candy-floss atmosphere.
The James Webb Space Telescope is up next — ready to peek into those atmospheres and tell us what these cotton-candy giants are really made of.
Every time we find something this weird, our neat little models of how planets form crack a little more.
And that's the point.
As Dransfield put it:
"By studying exotic systems containing rare planet types, we add further pieces to the puzzle of planet formation — and learn more about our place in the cosmos."
The universe keeps reminding us of one thing.
We barely know it.
And somewhere 1,100 light-years away, two giant balls of fluff are quietly proving it. 🎯
That's all for now!
