Solar Energetic Particles

The May 2024 solar storm created two new temporary belts of high-energy particles surrounding Earth. The findings are particularly important for spacecraft launching into geostationary orbits, which can be damaged as they traverse the dangerous belts.

On Aug. 8, NASA scientists may have spotted a record number of sunspots when hundreds of individual spots were estimated to occur within 24 hours.

The northern lights may be visible Tuesday and Wednesday over several northern states, from New York to Idaho.

Japan's LignoSat will test wood's resilience in space and could lead to a new era of more sustainable, less polluting satellites

A powerful solar storm in May 2024 created auroras on Mars and provided scientists with crucial information that could aid future crewed missions to the Red ...

An enormous "Miyake event"—a bombardment of Earth by particles from the sun—hit 14,300 years ago. Such an event today would have devastating effects

The Parker Solar Probe is the little engine that just keeps going and going by the sun. On September 27th, it made its 17th close approach and skimmed just 7.26 million kilometers (4.51 million miles) above the sun's "surface" layer (called the photosphere).

Spacecraft named for pioneering UChicago scientist ventures closer to sun than humanity has ever been

Mild solar storms can cause more serious problems to GPS satellites than once-in-a-century events, a new study has found.

Where was the radiation impact the worst? You might be surprised.

A coronal mass ejection erupted from the sun on 28 October 2021 and was spread over such a wide area that Mars and Earth, while on opposite sides of the sun and around 250 million kilometers apart, received an influx of energetic particles.

A solar eruption detected simultaneously at Earth, the Moon and Mars emphasises the need to prepare human exploration missions for the dangers of space radiation.

This discovery is literally the hottest thing in a while.

Solar flares and coronal mass ejections (CME) are two of the most energetic processes in the solar system, showering the Earth's magnetic field with billions of tons of highly energetic plasma gas, potentially disrupting power grids, satellites and communications networks. Understanding the underlying particle acceleration process involved in large solar energetic particle (SEP) events like these has been one of…

Scientists have examined the contributions of galactic cosmic rays and solar energetic particles associated with superflares from the young Sun to the formation of amino acids and carboxylic acids in the early Earth's atmosphere.

On Nov. 3 a solar storm caused a temporary crack in Earth's magnetic field. The resulting hole enabled energetic particles to penetrate deep into the planet's atmosphere and set off extremely rare pink auroras.
