Using observations from a NASA suborbital rocket, an international team of scientists has, for the first time, successfully measured a planet-wide electric field thought to be as fundamental to ...

An international team of scientists at NASA and other institutions say they've discovered a weak, planet-wide electric field wrapping the Earth that was first hypothesized by researchers decades ...

HARP uses data from five NASA satellites that launched in 2007 to help study auroras, which occur when solar particles run into Earth’s bubblelike magnetic field, or magnetosphere.

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles.

NASA wants to send a football field-sized radiator into space for its nuclear-electric Mars rocket It will be sent up in pieces and assembled by robots By Zo Ahmed January 15, 2025, 9:51.

NASA scientists have discovered a hidden electrical field around the Earth which could be just as important as gravity.

NASA scientists have discovered a planet-wide electric field surrounding Earth, confirming a 60-year-old hypothesis. Studying the field could yield some vital information about how our planet's ...

Before NASA's Hubble Space Telescope captured its iconic Hubble Deep Field, some astronomers were hesitant to take the ambitious imagery. But the director of Hubble's science mission took the risk.

Data from NASA shows the asteroid could hit Earth on that date, but it's likely to pass Earth by more than 1.1 million miles. "We've been tracking a new asteroid named 2023 DW that has a very ...
