A team of astronomers recently discovered something they didn’t predict in a “cosmic hamburger” — one of the biggest planet-forming disks of gas and dust, or protoplanetary disks, humanity has ever seen.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), a powerful array of 66 radio antennas located in northern Chile, the team discovered the first signs of planet formation in the dense gas layers of a system known as Gomez’s Hamburger (GoHam).
