Parker Solar Probe. Is the Universe Curved? Amazing Moon Photos.
2:01pm - 3:00pm
Parker has many new finds about the mysteries of the corona. Parker is doing many flybys between Venus and the Sun, and has already challenged some of the current theories of the Sun. The probe will run until 2025. The first details about the Sun are HOOOOOOT. The probe is 23 million miles from the Sun to measure the solar wind and the corona. Our previous views of the sun were simple. Parker has found cosmic dust stops at a distance of 3.5 million miles from the sun. Parker also saw magnetic waves from the sun flip in a whip like motion 180 degrees in a matter of seconds. These switchbacks came in clusters. The solar wind now is known to have rough irregular texture. The plasma lacks an orderly sense of direction. Some flies out but some falls back. Parker also found a transition point in the solar wind. The corona rotates with the visible surface before it transitions and Parker spotted signs of the transition, and it now is known that it happens farther out than expected. Parker also observed several outbursts of solar energetic particles. They have never seen to be this small before. Amazing photos of the terrain of the moon.
