NASA’s Solar Dynamics Observatory (SDO) has captured shocking images of how a furious spark from the Sun is about to bombard Earth.
According to Live Science, SDO – itself a spacecraft orbiting the Sun at an altitude of 36,000 km – has captured the flame classified as M-type, or medium intensity, above. This is the spark that caused the recent radio loss.
NASA says the original images obtained by SDO have 10 times the resolution of high-definition television images, providing many interesting and vivid details for scientists studying the mad mother star. our fury.

In the latest batch of images, colored for easy identification by the human eye, a bright spark can be seen with light in the extreme ultraviolet part of the spectrum, indicating that it has an extremely high temperature.
Class M “flares” are a rather powerful beam of energy, a sudden burst of explosive electromagnetic radiation from the Sun traveling at the speed of light to an unfortunate target – here the Earth.
The National Oceanic and Atmospheric Administration (NOAA) has classified it more specifically as an M.96, which means it’s not too far off to be the most powerful X-class.

According to NOAA, the spark captured by NASA caused a radio wave loss when it hit Earth. Radio waves travel across our planet by emitting particles that reach the upper ionosphere and then return to Earth. But this solar flare charged to the lower ionosphere, causing the radio waves to lose energy as they passed, swallowed up by the atmosphere.
This type of outage mainly affects air and maritime communications or other short-wave radio stations. The ionization process can also disrupt signal transmission from navigation satellites, such as those of the US GPS network.
This latest spark, born from sunspot number 2975, is considered magnetically complex and has fired a total of 20 raging sparks in the past week alone. A few sparks are associated with a coronal mass ejection (CME).
The CME reaches Earth more slowly than normal sparks but like a ticking time bomb, disrupting the planet’s magnetic field, triggering the beautiful aurora borealis. Last week, the aurora appeared on Wednesday night and early Thursday morning in Canada, northern parts of the US and in New Zealand.
