A NASA mission to study the heliosphere—the sun's magnetic bubble that shields our solar system—and develop a better understanding of space weather was launched from the agency's Kennedy Space Center along Florida's Atlantic coast on Wednesday morning.

Using the James Webb Space Telescope, scientists uncovered bizarre atmospheric structures on Saturn, including drifting “dark beads” in the ionosphere and an asymmetric star pattern in the stratosphere.

Created by the sun, the protective bubble of the heliosphere shields our solar system from harmful radiation. A new mission has launched to map it like never before.

NASA's Psyche orbiter looked back and snapped a photo of Earth with the moon on its way to the asteroid Psyche in 2029. - NASA / JPL-Caltech / ASU illustration As a NASA spacecraft whizzed away from Earth at 40,265 mph, it took a brief moment to look over ...

The spacecraft will map the boundaries of the heliosphere, study how Earth’s outer atmosphere reacts to solar activity and provide continuous monitoring of space weather

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather, NASA said.

An interstellar tourist is taking a quick trip through our solar system, becoming one of just three known objects to ever do so, according to NASA. A comet from a solar system outside our own was first noticed on July 1 by a NASA telescope located in Rio ...
