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.

While astronomers have previously seen young discs that contain newborn, massive, Jupiter-like planets, McClure says, “we’ve always known that the first solid parts of planets, or planetesimals, must form further back in time, at earlier stages.”

For the first time, international researchers have pinpointed the moment when planets began to form around a star beyond the sun. Using the ALMA telescope, in which the European Southern Observatory (ESO) is a partner,
