why nasa telescope keep taking pictures of sun every 4times per day?

Question

will only taking sun's pictures show us that science is growing up?
i think this is waste of time and waste of funds and resources. Our planet doest have any danger from Sun. lets move too far to discover and achieve better things in space rather than sticking around the sun. I think this probe is fruitless.



Why on our earth the sounds on the sun, which are the result of reactions taking place on it, can be heard? hopefull these sounds and explosions could be heard from near by planet mercury or venus!

Answer 1

The sun is a big ball of nuclear activity which occasionally flares up and sends damaging spikes of radiation our way called solar flares. These flares have the potential to greatly damage and destroy satellites, which in this day and age we rely heavily on.By monitoring the "weather" on the sun, much as we do on Earth, we can predict when a flare is likely to occure and if it's heading our way or not and sometimes satellite operators are able to put the satellites into modes or positions which would minimize the damage they receive.

We also think changes on the sun play an important role in large changes in the Earth's atmosphere.

The sun literally keeps us and our planet alive. It's important for us to know what it's doing.

Answer 2

Consider this. A solar flare can cause Aura Borealas and other electrical desurbances. Every satilite which orbits the earth is subject to being fried if a solar flare of sufficient magnitude strikes while it is in operation. That is military and Civilian satilites. We have become too dependant on these satilites day to day for that to not be a priority. GPS operates on 24 earth centric satilities. This is important to both the military and civilian sectors. If one of those satilites goes out without a backup, your OnStar will not work. Television from around the world gets around the world via satilite. The Internet is carried, in part, via satilite transmissions. I know this because I used to log into one satilite when I was configuring computers while I worked for Compaq for one of our customers. Our astranauts lives depend on being protected from solar flares which these satilites look for. When a solar flare is shot from the sun on a collision course for the International Space station, our people inside that station have less than 8 minutes to stop what they are doing and get to the protected areas of the station or risk death. Is this a good enough set of reasons to look at the sun? I think so.

Answer 3

The sun is essential to all life on earth (to a near approximation) so I don't think it's a bad idea to keep an eye on it and try to understand it.

I agree that the sounds made by the sun must be amazing, but sound cannot travel through the vacuum of space (contrary to what you may have seen on 'Star Wars' et al) so you wouldn't be able to hear anything from even a nearby planet. Remember, in space, nobody can hear you scream!

Answer 4

You are talking complete and utter nonsense. The sun is the only stellar body that has any serious effect in our every day lives. Climate, earthquakes, energy, tides, radio communications, electronics, structures and many many others are only a small fraction of the immediate effects to human every day lives by the sun.

By studying the sun we are studying an average star and by understanding its processes we understand how the universe works, how planets form how life came to being.

By the way what you say about "sounds" on the sun shows that your knowledge and understanding of Astronomy is very very small. I urge you to read some books on the basics before attempting to express any opinion on work of scientists that you do not understand.

Answer 5

Sun spots and other indicators of solar activity are important because they can interfere with satellites.

Also - the sun is the source of all life/energy on Earth - which makes it pretty important, right? I, for one, think we should keep a pretty good eye on it. While we do have TONS of theories, we really know very little about the sun - and we sure couldn't replace it if it went out!
