Many observatories have captured the Helix Nebula, but none in such detail as the Webb.

No one in NASA’s Artemis II crew had been born when astronauts last ventured into deep space for the final Apollo program ...

Solar Orbiter has captured the clearest evidence yet that a solar flare grows through a cascading “magnetic avalanche.” Small, weak magnetic disturbances rapidly multiplied, triggering stronger and ...

NASA explained that the flare was classified as an X1.9 flare. X-class flares are the most powerful type of solar flares. The number 1.9 shows how strong the flare was within this highest category.

Thick, swirling clouds cover Jupiter from pole to pole. They hold water like Earth’s clouds, but at far greater density. For ...

By contrast, Saturn's atmosphere is layered more deeply. There, either weaker forcing reduces deep turbulence, or more energy ...

New research shows how Jupiter and Saturn developed dramatically different vortices at their north poles. The findings may elucidate not only the planets’ surface weather patterns but also what lies ...

A conspiracy theory claims gravity will fail for seven seconds in 2026. The science is wrong—but what would happen if gravity ...

In a new study, scientists used advanced computer models to peer beneath Jupiter's dense swirling cloud tops and tackle a ...

A new study suggests lunar soil contains elements that solar wind transported to the moon from Earth’s atmosphere, solving a ...

Spectacular clouds swirl across the surface of Jupiter. These clouds contain water, just like Earth's, but are much denser on ...

The number of wildland fires burning in the Arctic is on the rise, according to NASA researchers. Moreover, these blazes are ...
