Could a solar storm destroy the earth? — City news


Not an empty question. Scientists have been asking them since they began noticing and predicting magnetic storms.

The other day we wrote about a fairly typical phenomenon for the Sun – a catastrophically growing double spot, which has already become several times larger than the Earth. The explosion of this place will almost inevitably cause a magnetic storm on Earth.

Billions of tons of solar matter rushes at a speed of thousands of kilometers per second, reaches the Earth and … affects our condition with some malaise, on communication satellites – malfunctions, on the atmosphere with stronger auroras, etc.

What if the lightning turns out to be twice, ten times more powerful? What then?

Many scientists insist that we are reliably protected from “outbursts of sun rage.” Solar storms affect radar and satellites to a greater extent, but the Earth’s atmosphere absorbs, quenches and scatters them so well that only the most sensitive of the planet’s inhabitants (and are they not suspicious?) complain of headaches.

The atmosphere of our planet is very dense – a real shield from solar flares. However, they are not harmless. It is not without reason that NASA experts closely monitor the sun’s behavior and record its potentially dangerous activity.

A significant part of the solar material is emitted as X-rays and ultraviolet radiation. But the intense energy from the explosion can greatly superheat the gas adjacent to the flare in the solar atmosphere. And additional bundles of “charges” rush out into outer space, which scientists called the coronal mass.

If the explosion occurs when our planet, orbiting the star, is opposite the ejection, the coronal mass “shoots” with aim. By the way, along the way, it loses speed and, depending on the initial impulse, reaches the Earth at different times. “On the road” it takes her from fifteen hours to several days.

Some NASA experts have expressed concern that such outbreaks could potentially cause an Internet apocalypse, leaving Earthlings without access to the global network for months.

But most scientists agree that the sun’s activity cannot affect life on Earth more significantly. During the four billion years that our planet has existed, the most serious disasters were caused by “stray” guests, comets, huge meteorites that traveled through space and flew into our cozy little solar system from outside. Although, of course, nothing can be ruled out. Therefore, astronomers continue to observe in all directions – both for the Sun and for other space bodies flying around.
