# This is your Astronomy Tonight podcast. Good evening, stargazers! Today is December 14th, and we're celebrating one of the most dramatic and scientifically profound moments in modern astronomy! On this very date in **2018**, NASA's Parker Solar Probe made its closest approach to the Sun, reaching a mind-bending distance of just **26.55 million kilometers** from the solar surface. But here's where it gets really wild – this wasn't just a casual flyby. The spacecraft was traveling at approximately **163 kilometers per second**, making it the fastest human-made object *ever*, absolutely obliterating the previous speed record! To give you some perspective, that's roughly **586,000 kilometers per hour** – fast enough to travel from Earth to the Moon in just four hours. The Parker Solar Probe was literally screaming through the Sun's corona, our star's outermost atmosphere, gathering unprecedented data about solar wind, magnetic fields, and the mysteries of coronal heating – one of astronomy's greatest unsolved puzzles. The engineering behind this achievement is nothing short of miraculous. The spacecraft had to survive temperatures reaching 1,377 degrees Celsius on its heat shield while instruments inside remained at a comfortable room temperature. It's like flying through an inferno while sitting in an air-conditioned cabin! If you're fascinated by humanity's daring missions to unlock the secrets of our Sun, please **subscribe to the Astronomy Tonight podcast** for more cosmic adventures.
