NASA SHARES IMAGERY OF COMET 3I/ATLAS, Nov 19, 2025, Greenbelt, MD/online, 3:00 pm ET

NASA will hold a live event at Goddard Space Flight Center in Greenbelt, MD on November 19, 2025 to share imagery of Comet 3I/ATLAS collected by NASA missions.  That includes the Hubble Space Telescope, the James Webb Space Telescope, and SPHEREx.  The comet flew within 19 million miles of Mars in early October and also was observed by NASA’s Mars Reconnaissance Orbiter and ESA’s ExoMars Trace Gas Orbiter.

The event will air on NASA+, the NASA app, the agency’s website and YouTube channel, and Amazon Prime.

The interstellar comet that is passing swiftly through our solar system was discovered on July 1, 2025 by the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) observatory in Chile. The “3I” designation is because it is the 3rd Interstellar object to be observed entering our solar system from elsewhere in the Milky Way galaxy, hence “3I/ATLAS.”

It poses no threat to Earth, coming no closer than 170 million miles (270 million kilometers).

Briefing participants are:

• NASA Associate Administrator Amit Kshatriya
• Nicky Fox, associate administrator, Science Mission Directorate
• Shawn Domagal-Goldman, acting director, Astrophysics Division
• Tom Statler, lead scientist for solar system small bodies
