NASA's Parker Solar Probe has now flown through the Sun's upper atmosphere - the corona - and sampled particles and magnetic fields there. Flying through the solar coronathat is the magnetic field-dominated region of the solar atmosphere. The Mach number drops below unity (one) when a field line transitions between two different coronal hole regions (the blue and red regions marked on the Sun). The X-59 is designed to demonstrate the ability to fly supersonic while producing just a quiet sonic thump instead of the loud sonic boom typically associated with supersonic flight.
NASA's Parker Solar Probe "Touches" the Sun - News For Kids Watch this video on the NASA Goddard YouTube channel. The corona is the upper atmosphere of the celestial light source, and reaching it has been likened to "touching" the Sun by NASA. This is only the beginning of Parker Solar Probe flying through the solar corona. The switchbacks origins were further narrowed when the scientists found the patches aligned with magnetic funnels that emerge from the photosphere between convection cell structures called supergranules. Beyond it (circle at right), the Suns magnetic fields and gravity are too weak to contain the plasma and it becomes the solar wind, racing across the solar system so fast that waves within the wind cannot ever travel fast enough to make it back to the Sun. The switchbacks are a reversal of the magnetic field. The black hole, which is less massive than any other black hole yet identified in the early universe, was discovered in a galaxy that existed just over 570 million years after the big bang. Parker Solar Probe has now touched the Sun, passing through the Suns outer atmosphere, the corona for the first time in April 2021.

Credits: NASA's Goddard Space Flight Center/Joy Ng Its magnetized and an active star and flying so close to it will tell us exactly how it works. In August, Parker Solar Probe will fly by Venus - using the planet's gravity to help set up an even closer perihelion in the future . This limit is defined by the distance at which disturbances in the solar wind cannot propagate back to the solar surface. It marks the transition to the solar wind which moves through the solar system. Closer to the solar wind's source, Parker Solar Probe is seeing a much different picture: a complicated, active system. Once there, it will . Until now, streamers have only been seen from afar. Artists rendition of the Parker Solar Probe in the suns atmosphere, or corona. One thing that were looking forward to is when Parker Solar Probe flies through one of the huge CMEs very close to the Sun and tell us how the solar energetic particles are accelerated to almost the speed of light.
For The First Time, NASA 'Touches' The Sun Until now, researchers were unsure exactly where the Alfvn critical surface lay. One theory suggests they might be created by waves of plasma that roll through the region like ocean surf. Parker Solar Probe launched aboard a Delta IV-Heavy rocket from Cape Canaveral, Aug. 12, 2018 at 3:31 a.m. EDT. These structures can be seen as bright features moving upward in the upper images and angled downward in the lower row. For humanity, it is a humungous stride.
