Scientists studied how space junk moved in orbit over a 36-year span, finding that increased solar activity caused it to fall to Earth faster.

A new Sun-centered and science-focused coloring book produced by NASA in partnership with the University of Alaska Fairbanks (UAF) is now available for people to learn while showing their artistic side.
Earth’s magnetic field is like a powerful trap. It lures electrically charged particles in space, near our planet, and snares them in an invisible, doughnut-shaped pen around Earth known as the ring current. This captive swarm of charged particles plays an important role in how Earth reacts to changing conditions in space, called space weather, which […]
The twin eruptions briefly disrupted radio signals across the dayside of Earth.
Acting as stellar archaeologists, scientists have found fossilized magnetism on long-dead white dwarf stars, which may help to explain how stars evolve.

“In the inner corona, a region very difficult to observe, we saw slow solar wind gusts moving three to four times faster than expected.”

An X1.4 solar flare triggered radio blackouts and launched a fast CME as NASA prepares for its Artemis 2 moon mission.

The powerful magnetic field belonging to the sun is generated far beneath the visible surface.
As four astronauts travel around the Moon on NASA’s Artemis II mission, they will venture beyond Earth’s protective magnetic field. The crew’s spacecraft, Orion, will carry and protect them as they journey into deep space and serves as the main protection against the Sun’s intense power. During their 10-day flight, NASA and the National Oceanic and Atmospheric Administration (NOAA) will monitor the […]
NASA’s Van Allen Probe A is expected to re-enter Earth’s atmosphere almost 14 years after launch. From 2012 to 2019, the spacecraft and its twin, Van Allen Probe B, flew through the Van Allen belts, rings of charged particles trapped by Earth’s magnetic field, to understand how particles were gained and lost. The belts shield Earth from cosmic radiation, solar storms, and the constantly streaming […]
