Data captured by the ALMA telescope in Chile and the James Webb Space Telescope showed planets forming around a star in the first record of its kind.

The astronomers observed hot minerals just beginning to solidify – the first specks of planet-forming material, the astronomers said. A gaseous disk surrounding the young star is the first stages of the assembly process to form a new planetary system, according to the paper.

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 solar system.
