Look: Astronomers clearly capture planets and moons forming in deep space

ESO/L. Calçada, ALMA (ESO/NAOJ/NRAO)/Benisty et al.

Nearly 400 light-years from Earth, two new planets are forming inside this giant circumstellar disc.

Inside that, a smaller disc is circling one of the planets.

Astronomers have long hypothesized that these circumplanetary discs exist, but it wasn’t until recent years that they actually spotted one in the universe.
