About 4.5 million years ago, a great cosmic dog kicked past our Solar System – and its effects may still be seen today.

Astrophysicists calculated that two stars, now located some 400 to 500 light-years from Earth, swung through our…

Astronomers have spotted what is likely the “largest spinning object” ever discovered, and its rotation could hold important clues about how galaxies develop.

The whirling structure, located 140 million light-years from Earth, is a long,…

Sometime in 2029, the European Space Agency is scheduled to launch its Comet Interceptor Mission. The Interceptor will wait for a long-period comet to arrive in the inner Solar System then set off on a trajectory to rendezvous with it….

NASA’s Perseverance rover has discovered several thousand small, light-toned rock fragments, or float rocks, with some exhibiting spectral signatures of an aluminum-rich clay mineral called kaolinite. To interpret their formation, planetary…

Scientists have taken a major step toward building catalysts that work atom by atom with unprecedented control.

Single-atom catalysts are often hailed as the future of cleaner, more efficient chemical reactions.

But making them work…

The NASA Science Activation project Eclipse Soundscapes (ES), led by ARISA Lab in Medford, Massachusetts, helps learners of all ages explore NASA science through multisensory learning and participatory science opportunities. In the weeks…

It’s getting harder and harder for the Hubble and other telescopes orbiting Earth to capture pristine images thanks to the sudden surge in satellite launches. Satellite trails could mess up nearly 40 percent of images the Hubble takes and up to…
