The NASA Parker Solar Probe is set to make the closest encounter with the Sun in history, diving into the star’s outer atmosphere under extreme conditions. Launched in 2018, the probe aims to unravel the mysteries of the Sun, including the inexplicable heating of its corona. The spacecraft will communicate its findings on December 27 after enduring temperatures of 1,400°C and traveling at speeds over 430,000 mph. Understanding solar activity is crucial for predicting space weather impacts on Earth.
