NASA Enters the Solar Atmosphere for the First Time Empty NASA Enters the Solar Atmosphere for the First Time

Post by Dragon Fri Dec 17, 2021 2:21 am

For the first time in history, a spacecraft has touched the Sun. NASA’s Parker Solar Probe has now flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there.

As it circles closer to the solar surface, Parker is making new discoveries that other spacecraft were too far away to see, including from within the solar wind – the flow of particles from the Sun that can influence us at Earth.

In 2019, Parker discovered that magnetic zig-zag structures in the solar wind, called switchbacks, are plentiful close to the Sun.

But how and where they form remained a mystery.

Halving the distance to the Sun since then, Parker Solar Probe has now passed close enough to identify one place where they originate: the solar surface.

As Parker Solar Probe passed through the corona on encounter nine, the spacecraft flew by structures called coronal streamers.

These structures can be seen as bright features moving upward in the upper images and angled downward in the lower row.

Such a view is only possible because the spacecraft flew above and below the streamers inside the corona.

Until now, streamers have only been seen from afar.

They are visible from Earth during total solar eclipses.

As Parker Solar Probe ventures closer to the Sun, it’s crossing into uncharted regimes and making new discoveries.

This image represents Parker Solar Probe's distances from the Sun for some of these milestones and discoveries.
