Eclipse in Chile & Argentina

A solar eclipse happens when the moon casts a shadow on Earth, fully or partially blocking the sun’s light in some areas. Observers within the path of totality will be able to see the sun’s corona (weather permitting). Watch online to experience the excitement!

Parker Solar Probe

Humanity’s First Visit to a Star

Parker Solar Probe is a historic mission, flying into the Sun’s atmosphere (or corona) for the first time! It will have 24 orbits around the sun, traveling at a top speed of 430,000 mph—the fastest man-made object ever! It can also withstand temperatures outside the spacecraft that reach nearly 2,500 degrees Fahrenheit (1,377 degrees Celsius)!
