Earth is an enormous magnet, its iron-rich core creating a shield of magnetic field that envelopes the planet —— well, almost. A “dent” in this magnetic field known as the South Atlantic Anomaly allows charged particles from the sun to dip closer to the planet in an area over South America and the Southern Atlantic Ocean.
Once a water-rich Eden, the hellish planet could reveal how to find habitable worlds around distant stars
New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 & 2 observations made decades ago. The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn’s magnetic field.
For centuries, scientists have worked to understand the makeup of Jupiter.
NASA is preparing to launch a cutting-edge, laser-armed satellite that will spend three years studying Earth’s changing ice sheets from above.
Citizen scientists, satellites and researchers solve the mystery of new purple lights in the sky. The lights, called STEVE, provide scientists insight into Earth’s magnetic field.
A team of planetary scientists from Brown University and NASA’s Goddard Space Flight Center has mapped the mineralogy of the South Pole-Aitken basin, a vast impact structure on the far side of the Moon. Published in the Journal of Geophysical Research: Planets, the findings could help guide future exploration of the basin.
Mars has an invisible magnetic ‘tail’ that is twisted by interaction with the solar wind, according to new research using data from NASA’s MAVEN spacecraft.
