Solar flares ☀️ Solar flares are huge bursts of energy released from the Sun. These intense bursts of radiation take just a few minutes to reach millions of degrees, and their effects can be devastating, causing blackouts and interfering with satellites. Solar flares sound scary, but they won't exactly destroy Earth. Occasional flares from the Sun could reach our planet if they are especially powerful, at which point they can cause damage to power grids. #freeAstroSci #FollowTheScience #scientif

The Sun emitted a strong solar flare on Nov. 30, 2025, peaking at 9:49 p.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.9 class: go.nasa.gov/4alXf6P Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel. To see how such sp

Explosions on the surface of the sun, known as solar flares, can have an impact on life and technology on Earth and experts say the sun is now in its most active period in two decades. Bill Murtagh is the program coordinator for the NOAA's Space Weather Prediction Center and described the sun as one big magnet with a north and south pole-- it also has negative and a positive polarity. Over the course of 11 years, the sun does a rotation of that polarity. "The sun is a big ball of electrically ch

The Sun emitted a strong solar flare peaking at 3:08 a.m. ET on May 27, 2024.

Today’s BIG solar flare is causing all these amazing northern lights. It peaked at X5.1 intensity—the strongest flare of 2025 so far and the most powerful since an X9.0 event in October 2024. Solar flares are ranked by their X-ray brightness in 5 classes (A, B, C, M, X), with each class representing a 10x increase in energy output. Within the X class (the most intense), the number indicates further strength. - X1: Baseline strong flare. - X5: About 5x stronger than X1, releasing energy equivalen
