JWST reveals a race against time for forming planets

Planets form from disks of gas and dust around young stars, but the gas needed for growth does not last forever. New observations from NASA's James Webb Space Telescope (JWST) now offer a new view of how this gas escapes ...

JWST peeks at Callisto's ancient scars

Of Jupiter's four Galilean moons, Callisto is the one that gets the least attention. Io is constantly being resurfaced by volcanoes. Europa has a giant liquid water ocean. And Ganymede has its own magnetic field that interacts ...

Interplanetary spacecraft capture a coronal mass ejection component hidden from Earth

During a coronal mass ejection (CME), the sun hurls billions of tons of magnetized plasma into space. These eruptions are among the most powerful events in the solar system, and when they are aimed toward Earth, they can ...

Neptune's tiny moons tell the story of Triton's destructive capture

Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all ...

Synchronized star pairs unleash radio bursts via a Jupiter-Io-like mechanism

Researchers have helped unravel the mystery of why certain pairs of stars pulse with regular, long-period bursts of radio waves. The particular class of objects observed comes in pairs that always include a compact dead star, ...

Proposed 900-telescope array could detect an Earth-like exoplanet's atmosphere in a single transit

What do you do when the observation you need comes around once a year? Well, preparation is key, but this is the awkward truth about finding another Earth. When a planet crosses the face of its star, a sliver of starlight ...
