A new study finds that hot super-Earths begin as large puffy worlds with low densities. Over time their atmospheres are stripped away to leave more dense planets orbiting close to
Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest picture yet of the probability that galaxies of different sizes host active black
Astronomers have long puzzled over how some massive galaxies stop forming stars and remain dormant for billions of years—even when they still contain gas that could, in principle, fuel new
SpaceX has the first of a series of afternoon launches in the next week on tap Friday with another Starlink mission from Cape Canaveral.

This year’s funding for the Mars Sample Return mission has been cut. It seems unlikely that the mission will be revived in the coming years, barring some unforeseen development. This
They’re called ghost particles for a reason. They’re everywhere—trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos. These so-called neutrinos are elementary particles that
