Solar flares, images from NASA

Solar flares, images from NASA






If the sun had not risen, there would be no new day on Earth. An absolute certainty is our star, as the magnificent ones show. Images captured by NASAis far from asleep. Indeed, the Sun is more active than ever, a “dynamic object,” as the American space agency astronomers describe it, able to observe (and photograph) one of them. sunlight busier than ever.


‘Cause the sun keeps on bursting

“The sun emitted a powerful solar flare that peaked at 4:25 p.m. EDT. October 2, 2022“, this is official correspondence Solar Dynamics Observatory A mission by NASA (and a team of associated scientists) that is fully concerned with the continuous monitoring and observation of activities affecting the sun’s surface and beyond.

There our star It has never been more active, and NASA images in particular show us for the first time one of the most intense solar flares ever observed. There are astronomers Classified as X1, where the letter X indicates exactly the class of the glow (highest), and the number instead indicates the value of its power (1 out of 9 in this case). Concrete proof of how we are progressing towards the highest peak of solar activitywhere exacerbations occur more frequently.

The images captured by NASA are nothing short of fascinating, just as their description: “The sun envelops most of the image in eddies. solar activity visible on its entire surface – reports Solar Dynamics Observatory – in different shades of orange dark rusty orange to almost bright yellow orange compared with the heat of solar materials. Among the swirling orange hues are some bright near-white regions of the Sun that highlight the extremely hot material of solar flare bursts. Along the outer circumference of the Sun, its light penetrates the darkness of space It creates blurry images at intersections. The background of the image is the darkness of space”.

what is sunburst

Observed by the Solar Dynamics Observatory last October 2, it is one of the most intense eruptions ever recorded, but solar flares are practically constant activities on the Sun’s surface. powerful bursts of energy A burst of electromagnetic radiation from the solar atmosphere, as well as creating the most powerful explosive events in our Solar System. “The most powerful flashes have energy. equivalent to one billion hydrogen bombsEnough energy to power the entire world for 20,000 years,” NASA explains.

Is solar flare dangerous for Earth?

thought to be light takes about 8 minutes For traveling from the Sun to Earth, the same goes for the energy emitted by a glow in the solar atmosphere. But does all this pose a danger to our planet or can we be sure?

It is true that solar flares hit the Earth, but only when they occur on the side of the Sun facing our Planet, and their effects clearly depend on the class to which they belong (B, C, M, and X, from least intense to most intense). When? solar radiation when it reaches us, the earth’s atmosphere takes care of absorbing most of it, so it’s actually a direct danger For the people who fill the world.

But there are still some risk factors. As NASA explains very well, more intense solar flares are affecting some of our technologies, particularly high frequency radio used for navigation and GPS: electrical fluctuations and flashes in the ionosphere cause radio signal interruptions that can last for minutes or even hours. Finally, flashes represent a danger. spacecraft and astronauts orbiting outside the Earth’s atmosphere.
