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 […]
Mars is not what it used to be. Once warm, watery, and blanketed by a thick atmosphere, today the Red Planet is cold, dry, and draped by a thin atmospheric veil. The main culprit is a relentless stream of particles from the Sun, known as the solar wind. Over billions of years, the solar wind has stripped away […]
The sun’s visible disk has been perfectly free from sunspots for the first time since June 2022, suggesting the current solar cycle might be heading toward its quieter phase.
…
An impulsive X4.2 solar flare sparked strong radio blackouts across Africa and Europe as the giant sunspot continues to rage.
…
A rapidly growing sunspot has fired off at least 18 M-class and three X-class flares in just 24 hours, including an intense X8.3 eruption.
