In the journal The Astrophysical Journal Letters, scientists on Tuesday announced compelling evidence for a world just 1.5 million years old, making it one of the youngest planets ever found, perhaps the youngest.

This planet is a newborn being cradled in the arms of its parent star.

As the suspected planet is shrouded by the matter that is making it, further telescopic observations will be required to confirm its existence.

But the location of this baby planet — firmly within the disk of primordial matter around its star — supports the idea that most planets spend much of their time growing up in a similar sort of nursery.

Benisty and her colleagues used ALMA to make the first unambiguous detection of a halo of gas and dust orbiting an exoplanet: a circumplanetary foundry still making the world it shrouded, and perhaps a few moons too.

For the latest study, they pointed ALMA at AS 209, a star just a tad heavier than the sun.

If so, “we also cannot rule out that our own solar system has a planet beyond Neptune,” he said — perhaps the hypothesized Planet 9 that some astronomers suspect is lingering in distant darkness
