NASA Michoud Gets a Rare Visitor

Comet C/2023 A3 (Tsuchinshan-ATLAS) passes over NASA’s Michoud Assembly Facility in New Orleans in this Oct. 13, 2024, image. This comet comes from the Oort Cloud, far beyond Pluto and the most distant edges of the Kuiper Belt. Though Comet C/2023 A3 will be visible through early November, the best time to observe is between […]

ESA, NASA Solar Observatory Discovers Its 5,000th Comet

On March 25, 2024, a citizen scientist in the Czech Republic spotted a comet in an image from the Solar and Heliospheric Observatory (SOHO) spacecraft, which has now been confirmed to be the 5,000th comet discovered using SOHO data. SOHO has achieved this milestone over 28 years in space, even though it was never designed […]
