Jupiter's south pole has a new cyclone.

After a year scoping out asteroid Bennu’s boulder-scattered surface, the team leading NASA’s first asteroid sample return mission has officially selected a sample collection site.

A type of Martian aurora first identified by NASA’s MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet.

Nearly a year and a half into its mission, Parker Solar Probe has returned gigabytes of data on the Sun and its atmosphere.

Everything you need to know about the Ionosphere, the boundary between Earth's lower atmosphere — where we live and breathe — and the vacuum of space.

They look like twins. But under the hood, the rover currently exploring the Red Planet and the one launching there this summer have distinct science tools and roles to play.

The spacecraft discovered that asteroid Bennu could be active, consistently discharging particles into space.

NASA’s OSIRIS-REx mission is just days away from selecting the site where the spacecraft will snag a sample from asteroid Bennu.

The Sun is revealing itself in dramatic detail thanks to NASA's Parker Solar Probe.

Four new papers in the journal Nature describe what scientists have learned so far from NASA's Parker Solar Probe.

Using data from NASA’s TESS, astronomers have captured an image of an explosive emission of dust, ice and gases from comet 46P/Wirtanen in late 2018.

This image shows the Vikram Lander impact point and associated debris field.
