Here's something you've never seen before: Pole North the Sun


We're very curious people about the nuclear furnace that has life powers on Earth. We have looked at the Sun in so many different ways, based on Earth and space. Yet, we have had a very difficult time to get a glimpse of its poles.

Now, solar mission has given us only that, in the form of an image that has gathered together data collected by the PROBA-2 (PRoject for OnBoard Autonomy 2) European Space Agency satellite, in an orbit around the Earth.

Our home planet – and most of the things in the Solar System – is covering the Sun in an airplane more or less, close to the star mediator. This is called the ecliptic plane, and this is the result of a dust and gas flat disk whipping around the Sunday baby, the planets formed from it.

We also launch a spacecraft on the ecliptic plane, for a practical reason. The Earth spin on its axis gives a little boost to a rocket, which means that it takes less effort to get in space. The closer launch to the equator, the more the boost. It would be much harder to launch a rocket from the Earth's polar regions.

So launches of Earth's rockets are already traveling in the ecliptic plane and therefore they are not usually able to look at the Sun's poles. Yes is It is possible to get out of this plane, but it's pretty hard and it takes a lot of time.

In fact, there was one researcher looking at the Sun's poles, however. NASA, the ESA and the Canadian National Science Council on Ulysses, who were overflowing the Sun's poles, worked at a distance of almost 322 million kilometers (200 million miles). That is over twice the average distance between the Earth and the Sun.

It was an absolute sporting unit. They had to send all the check to Jiwpiter. Then, once she got there, they had to slow it down to almost, then use Jüiter's lack of Ulysses out of the ecliptic plane.

Then there were only three giant Solo loops over 15 years, from 1994 to 2009. And we learned a lot of Ulysses – but none of the instruments was a camera.

This is the reason why we have never been able to see one of the Sun's poles directly with their eyes.

This time, we are not looking at a photograph either, strictly – but it's likely that it will be very close.

"Although the poles can not be seen directly, when a spacecraft observes the solar atmosphere they collect data on everything along their strand, and also look at the atmosphere that extends around the Sun's disc , "explained the ESA.

"Scientists can use this to find the appearance of the colonial regions."

Spread through a slide, when the Sun is rotated, PROBA-2 takes these elements in extreme ultraviolet wavelengths and combines to rebuild the Solar poles.

You can see the lines between the individual slices, and the line across the middle is created due to small changes in the solar environment over the timetable for which the data was collected.

ESA scientists have been building these images since June this year, and uploaded into a database so that they can observe how the Sun's poles change over time.

This is so that they can build on the information collected by Ulysses, and try to learn more about the dynamics of solar phenomena in the polar regions – such as coronal holes, Alfvén waves and Rossby waves.

The NASA Parker Solar Probe, launched earlier this year, has already come closer to the Sun than any other space ship. But he's not going to leave the ecliptic plane.

For real pictures, we may have to wait for the ESA Solar Orbiter, which was scheduled to launch in 2020. It will not go to orbit the poles, but it will go to rotate in very high latitudes that it will be able to visualize the mysterious and bad regions.
