Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July ...
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 ...
Our sun constantly releases a stream of high-speed charged particles, known as the solar wind. Unlike Earth, Mars does not have a strong global magnetic field to shield its atmosphere from this flow. As a result, the solar ...

We know Mars has water ice in its polar regions, but astronauts (and their solar-powered equipment!) would much rather experience life closer to Mars' equator. As NASA looks toward landing humans on the red planet, the Planetary ...
