Astronomers have found a rare sight in space that may have seen two planets collide, roughly 11,000 light-years from Earth, around a sunlike star called Gaia20ehk. The collision, which may echo the impact that created the Earth and moon billions of years ago, was captured on various telescopes in real time. The discovery could provide insight into the dynamics of the crash that created our moon. The team also hopes to use the powerful Simonyi Survey Telescope at the Rubin observatory to discover other planetary collisions that may be difficult to spot. The research was published in The Astronomy Magazine.
