Comet 3I/ATLAS: A Multi-Mission Observing Campaign
6 months agoUS
Interstellar comet 3I/ATLAS is under intense observation by multiple space missions as it traverses our solar system. ESA’s Juice mission and NASA’s Hubble Space Telescope are among the assets tracking this celestial visitor.
Key Insights
•
ESA’s Juice mission observed 3I/ATLAS with its science instruments and navigation camera in November 2025.
•
A test image from Juice’s NavCam revealed the comet’s coma and hints of plasma and dust tails.
•
Hubble reobserved 3I/ATLAS on Nov. 30, capturing its movement against background stars.
•
NASA missions are collaborating to gather as much data as possible before 3I/ATLAS exits the solar system.
Why this matters: Studying interstellar comets like 3I/ATLAS provides insights into the composition and conditions of other star systems. Observing it from multiple locations gives scientists a more complete picture.
In-Depth Analysis
Comet 3I/ATLAS, discovered in the summer of 2025, is an interstellar object making a temporary visit to our solar system. ESA’s Jupiter Icy Moons Explorer (Juice) used its science instruments to observe 3I/ATLAS in November 2025. Even a test download from Juice's NavCam revealed a glowing coma and hints of both plasma and dust tails. The image was taken on November 2, 2025, two days before Juice’s closest approach to the comet at a distance of about 66 million km. NASA’s Hubble Space Telescope also reobserved the comet on November 30, 2025, using its Wide Field Camera 3. The comet was approximately 178 million miles (286 million kilometers) from Earth at the time. Hubble tracked the comet’s movement, creating streaks from background stars in the images. Previous observations were made in July, and multiple NASA missions continue to study 3I/ATLAS as it departs the solar system.
