NASA's Parker Solar Probe came closer to the sun than ever before



The above image was taken by a probe of WISPR (Widepred Field Wide for Solar Probe) device on November 8 and it shows what is known as the coronal ribbon. These streamers are composed of solar material within the corona and tend to occur across areas of increased solar activity. This film appeared over the eastern limb of the sun and included at least two visible rays. You can also see Jupiter in the background – a bright spot towards the center.

"The heliophysists have been waiting for more than 60 years for such a mission," said Nikola Fuchs, director of NASA's heliophysics department.

The Solar Probe Parker will work to answer three main questions: How is the solar corona significantly warmer than the surface of the sun is visible, how is the solar wind that ejected from the sun as fast as it is and how some of the solar particles rapidly from the sun more than half the speed of light?

"Parker Solar Probe provides us with important measurements for understanding solar phenomena, which have puzzled us for decades," said Nur Raouafi, Parker Solar Project Probe at the Johns Hopkins University Applied Physics Laboratory. "To close the link, the local sampling of the Sun Corona solar wind and the young Parker needed Solar Probe does just that."

Measurements from this first solar encounter only began to be sent back to Earth on December 7, but scientists believe that a lot of good data was collected during the run. The second solar encounter should end in April 2019, and the spacecraft's mission is to continue until 2025.
