The USA's NASA space agency has set a new record. On Christmas Eve, its Parker spacecraft flew closer to the Sun than any spacecraft before by going. Parker left Earth in 2018 to photograph the Sun. Parker is also the fastest object ever made. In 2023, it flew at a speed of 635,266 kph.

Parker is named after a scientist. He spent his life studying the Sun. He wanted to know why the Sun's flares are hotter than the Sun's surface. The surface is 4,100ºC; while the flares can be 1.1 million degrees Celsius. Scientists also want to find out how solar winds start.
