Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are accreting debris from disintegrating exoplanets. Captured while DESI was unable to study its primary targets: distant galaxies, the results provide unprecedented insights into the chemical makeup of rocky exoplanets, revealing compositions remarkably similar to the planets and asteroids of our own inner solar system.

But now, a new study, published in Science Advances, has found that very thin layers of RuO2 can become magnetic when its lattice is placed under strain.
