This artist's illustration shows a white dwarf star surrounded by a debris disk with three asteroids orbiting in the disk.
Asteroids torn apart near white dwarfs may leave large fragments rather than immediate dust, revealing a missing stage in the evolution of planetary debris.

Earth’s tidal pull could have concentrated heat near the Moon’s core-mantle boundary, as illustrated by the glowing regions in this cutaway. The heating pattern is a model prediction; sizes and distances are not to scale.

This artist’s concept shows what a thick atmosphere above a vast magma ocean on exoplanet TOI-561 b could look like. Measurements of light captured from the planet’s dayside by NASA's James Webb Space Telescope suggest that in spite of the intense radiation it receives from its star, TOI-561 b is not a bare rock.
