NASA's MAVEN mission and the Hubble Space Telescope have teamed up to reveal new insights into how Mars' water is leaking into space.

BepiColombo made a close flyby of Mercury on Sept. 4, getting just 103 miles (165 kilometers) above the planet.

Energy-packed plasma waves pump enough energy into streams of solar wind to propel them to their unexpectedly high speeds, observations by two sun-studying spacecraft suggest.

A colossal asteroid slammed into Jupiter's largest moon Ganymede with so much power it dramatically and permanently reoriented the moon roughly 4 billion years ago, new research suggests.

A 3-foot (1-meter) asteroid burned up harmlessly over the Philippines today (Sept. 4) after being detected just this morning.

Any lunar resource evaluation or prospecting campaign will need to be international in nature, as no one space agency will have the money or mandate to conduct it alone.

A long-sought invisible electrical field wrapped around Earth has been detected more than half a century after it was first predicted to exist.

NOAA is researching how to update its Space Weather Scales and how it can better communicate its space weather forecasts with the public and government agencies.

Structures that scatter seismic waves deep in Earth's mantle seem to be everywhere researchers look.

Slower moving particles blasted out by the DART impact on the asteroid Dimorphos could create meteor showers on Mars — but it's unlikely they'll cause meteor showers over Earth.
