NASA Researchers Discover More Dark Comets

These celestial objects look like asteroids but act like comets now come in two flavors. The first dark comet — a celestial object that looks like an asteroid but moves through space like a comet — was reported less than two years ago. Soon after, another six were found. In a new paper, researchers announce […]

5 Surprising NASA Heliophysics Discoveries Not Related to the Sun

With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve mysteries about of the solar system and beyond.

November’s Night Sky Notes: Snowballs from Space

by Kat Troche of the Astronomical Society of the Pacific If you spotted comet C/2023 A3 (Tsuchinshan-ATLAS) in person, or seen photos online this October, you might have been inspired to learn more about these visitors from the outer Solar System. Get ready for the next comet and find out how comets are connected to […]

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 […]
