An artist’s rendition of interior compositions of planets around Kepler-102 and Kepler-407. The picture shows what minerals are likely to occur several different depths. An exoplanet in orbit around Kepler-102 is Earth-like, dominated by olivine minerals, whereas a planet around Kepler-407 is dominated by garnet, so less likely to have plate tectonics.

This illustration shows several comets speeding across a vast protoplanetary disk of gas and dust and heading straight for the youthful, central star HD 172555. These exocomets will eventually plunge into the star and vaporize. HD 172555 represents the third extrasolar system where astronomers have detected doomed, wayward comets. All of the systems are young, under 40 million years old. Image credit: NASA / ESA / A. Feild & G. Bacon, STScI.
