Space probes now soar through the galaxy to explore the mysteries of Mars Venus the outer Giants the distant exoplanets and the farthest stars but our own home star still.
Has its unsolved mysteries that’s about to change previously we’ve looked at small areas not the whole disk or we’ve had gaps in our coverage where we’ve looked for a day or we’ve not looked for a day we’ve looked for part of a day but not the whole time so this is really our first chance to look at the Sun as a whole star a high-tech solar probe arrives in space locked and loaded it’s mission watch the Sun 24/7 in high-definition color and transmit mega broadband images.
Back to earth the Solar Dynamics Observatory takes images of the Sun in very high resolution high-definition in many wavelengths and essentially it takes movies of the Sun using four HD telescopes the sdo transmits an unblinking hi-def like channel to earth uploading 50 times.
More science data than any probe mission in NASA history it was really exciting to look at some of the first images what we saw was very.
Small features in one place having a big effect someplace else so we could see something near the center of the disk center of the Sun and you can.
See the connection between that and what was happening a hundred thousand two hundred thousand miles away the advanced optics watched the Sun in ten different light.
Wavelengths including the extreme ultraviolet this wavelength is so deadly that without Earth’s upper atmosphere to filter it a day at the beach would be fatal our eventual goal is to look inside the Sun to see.
What’s happening below the surface what the currents are what the motions are and how that all ties together in a big picture the sto will activate a sensor the helioseismic magnetic imager that can see through the scorching solar.
Surface peculiar seismic and magnetic imager we’re using sound waves to probe inside just like we do in a seismic.
Way for earthquakes we can use sound waves inside the Sun to look at see what’s happening inside so we look at the vibrations as they bounce off the surface and then try and figure what’s.
Happening inside the Sun it’s this inner core the solar dynamo at scientists most want to demystify from here come the unpredictable violent eruptions.
Of high-energy material that can threaten the earth so that material is charged often in the form of what’s called a coronal mass ejection it’s a huge amount of material in the form of charged particles those charged particles arrive here at Earth and interact with our magnetic field if you can.
Get close enough to do direct measurements on that sort of activity we’d better understand how those processes were getting close to planetary bodies is something space probes have been doing for half a century but getting a.
Probe close to the Sun is a suicide mission or is it scheduled for launch in 2015 Solar Probe plus will fly directly into the Suns two million degree Corona.
And survive Solar Probe plus.
Will get very close to the Sun with an eight or nine solar radii from the Sun now for comparison the earth is 200 solar radii from the centre of the Sun so Solar Probe plus is going to be immersed within the corona the corona is a mysterious part of.
The star we call the Sun though farther from the Sun’s core it’s actually hotter than the sun’s surface but if a human were to somehow get there they’d get a frigid surprise the solar corona.
Is very hot millions of degrees in temperature that means the particles are moving around very very rapidly so you might.
Think that if you were immersed in the corona you would get burned but there are so few particles that the total amount of energy being transferred to a body is less than the amount of energy being radiated so in fact you would freeze if you were immersed in the solar corona as long as you had a good heat.
Shield protecting you from the disk.
Of the Sun solar probe plus will come equipped with a lightweight carbon foam heat shield allowing it to survive the massive heat the freezing effect and even operate near room temperature when it completes its mission Solar Probe plus will reveal the structure of the sun’s magnetic fields and explore the flow of solar energy that heats the Sun’s corona and makes life on our planet possible it’s important to remember that the Sun is the nearest star so really it’s important to study the Sun as part of the entire enterprise of studying all the stars in the.
Universe ultimately space probes will bring us knowledge far beyond the Sun and into the distant parts of our galaxy where billions of other Suns burn and potentially a few blue planets await future human explorers to learn some of the most amazing secrets about our universe we need spacecraft.
Because they can go places and see things that we could never do from here on earth there’s a deeper reason that we send probes out into space we humans have it in our DNA to be curious and to explore and of course probes that we send into space to the planets and ultimately to the stars represent our migration into the cosmos it is almost certainly our destiny as a species to crawl off the planet.
Earth and out into our galaxy and the universe as a whole until that day space probes will continue to peel back with wonders of the cosmos and the universe will continue to give up her secrets as these robotic avatars pursue humanity’s quest for the stars.
