Four of Our Favorite SOHO-discovered Comets

The video discusses NASA's Sungrazer project, which allows global citizens to discover new comets using images from the ESA-NASA Soho satellite. The project recently celebrated its 4000th comet discovery. The video highlights notable comet discoveries, including those from the Kroetz Group, and explains the significance of sun grazers. It also emphasizes how these discoveries provide insights into the sun's environment. The video concludes by acknowledging the contributions of NASA, ESA, and citizen scientists in achieving this milestone.
