CAPE CANAVERAL, Fla. — Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

It’s an unprecedented snapshot of “time zero,” scientists reported Wednesday, when new worlds begin to gel.

“We’ve captured a direct glimpse of the hot region where rocky planets like Earth are born around young protostars,” said Leiden Observatory’s Melissa McClure from the Netherlands, who led the international research team. “For the first time, we can conclusively say that the first steps of planet formation are happening right now.”

The observations offer a unique glimpse into the inner workings of an emerging planetary system, said the University of Chicago’s Fred Ciesla, who was not involved in the study appearing in the journal Nature.

“This is one of the things we’ve been waiting for. Astronomers have been thinking about how planetary systems form for a long period of time,” Ciesla said. “There’s a rich opportunity here.”
