Astronomers Find the Universe’s Newest Planetary Kitten

A record-young exoplanet gets a fictional visit from the Cosmic Cat Council—then the real astronomy behind Elias 2-24 b.

The Interstellar Department of Very Small Things has confirmed that the universe’s newest celebrity is not a kitten, although it is less than a million years old, surrounded by dust, and already responsible for a conspicuous gap in the furniture.

Elias 2-24 b, a young giant planet roughly 450 light-years away, was welcomed overnight by the Cosmic Cat Council. The council immediately issued a ceremonial cardboard box measuring 55 astronomical units from its host star and asked the planet to stop growing before it became impossible to carry.

“We have examined the evidence,” announced Professor Marmalade, senior astronomer and part-time curtain inspector. “This object is extremely young, very large, and spinning through a cloud of debris. We therefore classify it as a planetary kitten.”

The classification was challenged by dogs, who noted that the planet may weigh several times as much as Jupiter and has no visible whiskers. The cats rejected the objection on procedural grounds, explaining that dogs are not permitted to define “small” after repeatedly calling themselves lap animals.

The nursery with a 55-AU playpen

Unlike older planets, which have had billions of years to tidy their orbits and pretend they understand taxes, Elias 2-24 b is still embedded in the disk of gas and dust around its star. Astronomers found it sitting in a narrow gap in that disk—the celestial equivalent of discovering one kitten in the exact empty strip where every pen has vanished.

Cosmic Cat Council engineers said the gap was “highly consistent with active paw-work.” They have installed seven scratching posts, three toy moons, and one red laser dot that has already crossed into a neighboring constellation. Officials stressed that none of these items exists outside this satire.

The planet was spotted in archival observations from the Keck Observatory’s NIRC2 instrument, which uses a coronagraph to block a star’s glare and reveal faint companions nearby. Professor Marmalade described this as “putting one paw over the bright bit so you can see who is stealing the treats.” Human astronomers may phrase it differently.

The discovery is awkward for current planet-formation models. Previous record-holding young planets were more than five million years old. Elias 2-24 b appears to be no older than about one million years, suggesting giant planets can become detectable surprisingly early—or that theorists need to check under the sofa cushions of physics.

For now, the council has imposed three nursery rules: no chasing comets after bedtime, no accreting unsupervised snacks, and absolutely no knocking the host star off the table. Elias 2-24 b has not agreed to the terms, but it has continued orbiting, which officials called “the strongest response normally available from a planet.”

The real news behind the joke

A peer-reviewed study published on September 16, 2026, reports confirmation of Elias 2-24 b in a narrow gap within the young star’s protoplanetary disk. The team analyzed archival high-contrast observations made with the Keck Observatory’s NIRC2 vortex coronagraph. The paper places the planet about 54.9 astronomical units from its star and estimates a mass of roughly 1.9 to 4.0 times Jupiter’s mass, depending on model assumptions.

The system is about 450 light-years from Earth. With an estimated age of no more than one million years, the paper describes Elias 2-24 b as the youngest exoplanet discovered to date. NASA notes that such embedded worlds are hard to observe because dust hides them and because common transit searches favor planets close to their stars. Finding more systems like this one can help astronomers test how quickly giant planets form and how they carve gaps in surrounding disks.
