Question

Can you please help with the following questions:

What effects does a large Sun-spot system have on the Earth?

How can astronomers explore the layers of the Sun below its surface?

Why don't space-craft melt in the heat of the million degree corona?

Thanks for you input!!!

Answer 1

sunspots and the subsequent solar flares and prominences that come with them cause northern lights on earth (and other planets). they can also cause interference with cell phones and tv signals.

they explore the lower layers by looking at the sun through different telescopes and filters. if you look at it in the infra red it looks different than it does from a visible light perspective, or from x-rays. different wavelengths of light show different depths, we can never see right to the core, and what we know of the inner layers is from calculations and models of what happens inside of a star.

a spacecraft would melt, which is why none have been sent that close. most sun explorer crafts stay by earth and observe from there, there is no need to get into the sun's corona.

Answer 2

I saw an episode done about the sun in that series on the History Channel that was called "Secrets of the Sun".

It mentioned in there that the sun spots when they face the earth can create sun storms and when these storms occur they can cause power grids to fail. They gave some other examples as well.

It also mentioned that the core of the sun is 27,000,000 degrees hot. Because of how hot the core of the sun is it would be as the last poster said the spaceship would melt.

Scientists measure the sun with the help of computer models such as thru agencies at NOAA (the one also known for keeping an eye on hurricanes during hurricane season).

This program from The History Channel was amazing. I saw this episode thru my cable system's On Demand service.

Answer 3

Violent geomagnetic storms might consequence if a huge sunspot equipment looks on the sunlight. Sunspots are areas the place magnetic field lines replace into fairly twisted. whilst they adjust into twisted, vast quantities of means gets stored up,and whilst the magnetic field can undergo not greater, that means is released as effectual photograph voltaic flares and coronal mass ejections. those might reason means grids to fail with the aid of fact the geomagnetic storms that consequence whilst the CME's hit the Earth's magnetic field. they'll bring about extensive electric currents in means lines and ruin transformers and different kit. large electric currents will additionally be brought on in pipelines or perhaps the oceans, inflicting corrosion and different issues. large doses of gamma and x-rays will hit the better environment and something in earth orbit. An astronaut accessible ought to get a deadly radiation dose, and satellites could be disabled or destroyed. Even human beings aboard severe flying airplane close to the poles may well be in grave risk or radiation ailment or cancers brought about with the aid of radiation exposure. The Earth's magnetic field will additionally replace into overloaded, and hurl plasma down magnetic field lines to the ambience around the magnetic poles, sparking the northern and southern lighting fixtures. a large photograph voltaic flare will jam radio communications, and systems and people who rely on issues such with the aid of fact the international Positioning Satellites ought to locate themselves no longer able to the two talk or navigate for hours or days at a time.
