NASA recently shared an image capturing the Sun as it proudly displays its flares. The caption accompanying this image playfully reads, "Sunny, thank you for the sunshine bouquet." It goes on to describe how the Sun, with its vast size and magnetic influence, has a profound impact on everything within our solar system. In the image, the Sun appears as a mesmerizing swirl of orange and yellow hues, with a prominent burst of orange and red emanating from the lower left corner. On the Sun's surface, yellow cracks extend into the surrounding dark space. What is coronal mass ejection (CME)? The Sun's upper layer, known as the corona, is filled with plasma and governed by intricate magnetic fields. Temperatures in the corona can soar to millions of degrees. This region serves as the source of solar winds and coronal mass ejections, shaping the dynamics of our solar system. End of the article
The video's caption further explains that the Sun's atmosphere is a dynamic place where significant events like solar flares and coronal mass ejections (CMEs) take place. The Near Earth Solar Dynamics Observatory recorded a CME in September 2012, which travelled at speeds exceeding 900 miles per second, resulting in the appearance of a mesmerizing aurora.
Think of it as a substantial cloud of solar flares accompanied by magnetic fields that the Sun releases during intense bursts of heat. These CMEs can reach incredible heights, spanning millions of miles. When they interact with Earth's magnetic field, we're treated to awe-inspiring auroras dancing across the polar skies. However, they can also disrupt satellites and power grids due to their intense energy. For astronauts in space, prolonged exposure to unfiltered UV rays from CMEs can damage skin cells and increase cancer risks. Essentially, CMEs are like radiant bursts of sunlight that impact everything in their vicinity.
