a Total of 24 times, the Nasa probe, “Parker Solar Probe to fly” by the atmosphere of the sun. 31. October to 11. November of 2018 took their first flight. Now Nasa has released the first pictures of the record flight.

On 8. November was a record at the time of the probe was 27 million kilometres from the sun and its outer atmosphere, the corona. You are out of energy gases, which exudes the sun-rich.

to see With the naked eye the corona from earth is only in the case of a total solar Eclipse as a halo around the sun. The probe image, however, shows two intense particle flows from the sun at close range. Beams of left light in the picture.

The recording was put together from a plurality of sequentially shot photos. This is also an interesting effect: The round, white point slightly to the left of the center of the image of the big gas planet Jupiter. He moved to the time of the recording by the field of view of the camera. Thus, the black points can be explained. Also there Jupiter was at other points in time. In the case of the processing of the image he was expected then, but by the Software.

“has something nobody had seen,” said project scientist Nour Raouafi from the Johns Hopkins University Applied Physics Lab in Laurel (Maryland) on the image at the annual meeting of the American Geophysical Union (AGU) meeting in Washington.

“Parker Solar Probe” for the shot so close to the star flew past like no other probe. The previous record holder, the German-American Mission, “Helios”, had in the seventies, almost double the distance. In the following orbit, you will approach the sun even more.

Outside the sun’s atmosphere is particularly hot

in contrast, as one might intuitively think, it is in the outer atmospheric layer of the sun is hotter than in the closer to the star nearby areas. Up to 5.6 million degrees Celsius in the corona Lord. At the sun’s surface the temperature is only at 5500 degrees.

Until today, researchers have not understood exactly why the suns atmosphere is outside, so hot. “Parker’s Solar Probe” to investigate the phenomenon in more detail, by missing particles as well as magnetic and electric fields in the corona.

Here, the probe must withstand temperatures of about 1370 degrees Celsius. Almost twelve inches of thick carbon armor protects you from too much radiation. The particle flows from the sun are sometimes so strong that they can affect the magnetic field of the earth. Experts fear that, when a particularly fierce sun, would make the storm the earth, damage is in the trillions-height could occur(read more here).

In addition, flights should approach the probe to the sun, up to 6.2 million kilometers. The next corona by flight is scheduled for April 2019. Then, the probe should not send additional data from the first investigation, which arrive currently, due to an unfavorable Position.

The sun is, so to speak, between the “Parker Solar Probe” and of the earth. Lost the data. The probe have enough memory capacity to the measurement data of two full Orbits, onboard cache, so the researchers

on the way the probe is in August 2018. In the future, they should also clarify how solar winds to be accelerated within a short period of time. Some of the most energetic particles from the sun shoot, with more than half the speed of light into space.
