First-ever: We've identified a new astronomical object, 'Buried Planet', using SEISMOLOGY, rather than telescopes. It's a survivor of Theia, the planet that collided with Earth 4.5 billion years ago to form our Moon. See our @Nature cover paper: rdcu.be/dp16K
Cred: Hernán Cañellas If the two mantle blobs are remnants of the ancient impactor planet, could other rocky planets also have a 'buried planet'? Planetary seismology, missions like @NASAInSight may help us probe the earliest solar system's history, particularly for Venus which does not have a moon.
