This illustration shows a debris disc around the white dwarf J1328−1450 –– the dead core of a star similar to our Sun that expelled its outer layers at the end of its lifetime.
Astronomers found two chemically distinct gas rings around a white dwarf. Hidden planetary bodies may sustain them, offering clues to our Solar System’s future.

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.
