With the help of thousands of citizen scientists, a new study measured exactly how much brighter night skies are getting every year.
NASA has been gaining momentum in recent years as investment into space has ramped up in the US. In 2022, missions dealt with the farthest, closest, hottest and coldest conditions in the universe.
