A NASA mission, IMAP, and two more spacecraft that will study space weather are traveling through space atop a single SpaceX rocket.

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.

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.

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

NASA’s Magnetospheric Multiscale Mission has uncovered surprising behavior of pickup ions drifting through the solar wind near Earth. These particles, once thought to be minor players, appear capable of generating waves and influencing how the solar wind heats and evolves.

NASA has discovered a new interstellar comet that's currently located about 420 million miles away from Earth. The space agency spotted the quick-moving object with the Atlas telescope in Chile on Tuesday and confirmed it was a comet from another star system.

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 ...

Scientists have just discovered a rare interstellar object hurtling through the solar system, and it's expected to make its closest approach to Earth on October 30. Officially named 3I/ATLAS, the comet was first observed on July 1 by the NASA-funded ATLAS ...

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.
