Astronomers have detected the presence of a disc around a planet outside our solar system for the first time.

which is partially run by the European Southern Observatory , astronomers saw the disc, called a “circumplanetary disk,” surround the exoplanet PDS 70c, one of two giant Jupiter-like planets orbiting a star nearly 400 light-years away.

Using ALMA, Benisty and the team found that the disc has approximately the same diameter as the distance from our Sun to the Earth and enough mass to form up to three satellites the size of the Moon. Planets form in dusty discs around young stars, carving out space as they collect material from the disc to grow. In this process, a planet can acquire its own circumplanetary disc, which contributes to the growth of the planet by regulating the amount of material falling onto it.

But astronomers do not yet fully understand the details of these processes. "In short, it is still unclear when, where, and how planets and moons form," said ESO researcher Stefano Facchini, in the release. "This system therefore offers us a unique opportunity to observe and study the processes of planet and satellite formation.”

it's not for everyone

This is good news. Maybe it'll take the heat off of the CanadiensMTL . I hope the scientists involved in spotting this glorious vision don't have a checkered past. That would be a shame to have to cancel them.

Should we all start to panic just in case.

This is nuts in the coolest possible way.
