Strongest Solar Storm in 20 Years Hits Earth
A very strong solar storm hit Earth on January 18-19, 2026.
It was the strongest in over 20 years.
The storm was caused by a big explosion on the Sun called a solar flare, which sent a lot of charged particles towards Earth.
These particles caused beautiful lights in the sky called auroras, which were seen in places like California and Germany.
The storm also caused some problems with radio communications, satellites, and power grids.
Scientists are studying the Sun to understand these storms better, and India even sent a mission called Aditya-L1 to learn more about the Sun.
The storm was so strong that it was ranked 4 out of 5 on the intensity scale.
It also made the Earth's magnetic field very active, which can affect many things on our planet.
A powerful solar radiation storm struck Earth on January 18-19, 2026, ranking 4 out of 5 on the intensity scale.
The storm was caused by an intense X-class solar flare, the strongest in 23 years, sending a fast coronal mass ejection (CME) towards Earth.
The CME hit Earth's magnetic field, escalating geomagnetic conditions to severe G4 storm levels.
The storm triggered stunning auroral displays, visible as far south as Southern California, Greenland, Austria, and Germany.
The storm can disrupt radio communications, satellite operations, power grids, and pose risks to astronauts and airline passengers.
