Other active spacecraft monitoring the Sun include SOHO, ACE, IRIS, WIND, Hinode, the Solar Dynamics Observatory, and STEREO. The corona is the outer atmosphere of the Sun. It Took 100,000 Photos to Put Together This 230-Megapixel Picture of the Sun. NASA Releases First Photo Ever Taken from Inside the Sun’s Corona. NASA Shares Spectacular 10-Year Time-Lapse Video of the Sun. But when you walk away from the fire, you feel cooler. NASA Releases Incredible Photo of ISS Passing Across the Sun. Other dazzling images reveal the upper atmosphere of the sun, dubbed the corona which has a temperature of more than a million. Imagine that you’re sitting next to a campfire. It’s not exactly clear what the campfires are yet, NASA noted. Image credit: NASA The corona’s high temperatures are a bit of a mystery. 9, 2020 – is a joint mission between ESA (the European Space Agency) and NASA to collect data that will help answer a central question of heliophysics: How does the Sun create and control the constantly changing space environment throughout the solar system? Image of corona from NASAs Solar Dynamics Observatory showing features created by magnetic fields. Parker Solar Probe is designed to swoop within about 4 million miles (6.5 million kilometers) of the Sun's surface to trace the flow of energy, to study the heating of the solar corona, and to explore what accelerates the solar wind. This marked the first time in history that a spacecraft had touched the Sun. 14, 2021, NASA announced that Parker had flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there. The Sun as seen by the ESA/NASA Solar Orbiter spacecraft on March 25, 2022, one day before its closest approach of about 0.32 au, which brought it inside the orbit of. The electrically charged particles themselves are called a plasma. NASA’s Parker Solar Probe is studying our star from closer than any other spacecraft. The particles in the corona are electrically charged and follow the Sun’s magnetic field lines out into space. NASA and other international space agencies monitor the Sun 24/7 with a fleet of solar observatories, studying everything from the Sun’s atmosphere to its surface.
