Interstellar comet 3I/ATLAS, formally designated C/2025 N1 (ATLAS), is making a significant appearance in December 2025. Discovered on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System telescope in Chile, this comet is only the third confirmed interstellar visitor to our Solar System. It is characterized by a hyperbolic orbit, indicating it is not gravitationally bound to the Sun and is merely passing through. Recent observations have revealed high levels of methanol and hydrogen cyanide, molecules associated with the origins and destruction of life. Despite speculative claims of alien origins, NASA and experts assert that 3I/ATLAS is a natural comet. The comet is currently moving away from the Sun and will make its closest approach to Earth on December 19, 2025, at a safe distance of 1.8 astronomical units.

Hubble Telescope Captures Active Interstellar Comet 3I/ATLAS, Revealing New Insights

The Hubble Space Telescope has captured a new image of the interstellar comet 3I/ATLAS, confirming its active state even after its close approach to the Sun. Taken on November 30, 2025, the image shows the comet's bright nucleus surrounded by a coma of gas and dust, with background stars appearing as streaks due to the comet's rapid motion. This observation is significant as 3I/ATLAS is only the third interstellar object observed in our solar system. The data from Hubble, along with observations from NASA's Psyche mission and ESA's JUICE spacecraft, are helping scientists refine their understanding of the comet's trajectory and behavior. The comet is currently moving away from the Sun and will be closest to Earth around December 19, 2025.

NASA and the European Space Agency (ESA) have released new images of the interstellar comet 3I/ATLAS, which is making its final pass through the inner solar system. Discovered in late June and confirmed in July as the third known interstellar object, the comet is traveling at an estimated speed of 130,000 mph. It will make its closest approach to Earth on December 19, at a distance of approximately 170 million miles. The Hubble Space Telescope captured images of the comet's nucleus and coma, showing a bright white glow against streaked stars. The European Space Agency's Jupiter Icy Moons Explorer (Juice) also captured images, revealing a glowing coma and twin tails. These observations are part of a broader effort by various spacecraft to study the comet as it approaches Earth.

The Hubble Space Telescope has captured new images of the interstellar comet 3I/ATLAS as it nears its closest approach to Earth. This comet, originating from outside our solar system, was first observed in July and has been the focus of numerous missions due to its unique trajectory and composition. On November 30, Hubble's Wide Field Camera 3 provided a detailed view of the comet, which is currently 178 million miles from Earth. The European Space Agency's Jupiter Icy Moons Explorer also captured images of the comet, revealing two tails and a glowing halo of gas. The comet will come within 167 million miles of Earth on December 19, posing no risk to the planet.

NASA has released a new image of the interstellar comet 3I/ATLAS, captured by the Hubble Space Telescope on November 30, 2025. The image, taken when the comet was approximately 286 million kilometers from Earth, shows the comet's nucleus and coma with background stars appearing as streaks due to Hubble's tracking. This comet, discovered on July 1, 2025, by the ATLAS survey telescope in Chile, is only the third known interstellar object to pass through our solar system. The comet's path is hyperbolic, indicating it is not bound by the Sun's gravity and will not return once it leaves. Hubble's observations reveal a bright central coma surrounded by a teardrop-shaped halo and a sunward-pointing 'anti-tail,' a streak of dust and gas extending toward the Sun. This phenomenon is attributed to perspective and the distribution of dust grains along the comet's orbit.

Hubble and Juice Capture New Images of Interstellar Comet 3I/ATLAS Approaching Earth

The Hubble Space Telescope and the Jupiter Icy Moons Explorer (Juice) have captured new images of the interstellar comet 3I/ATLAS as it nears its closest approach to Earth. Discovered in July, 3I/ATLAS is only the third interstellar object observed passing through our solar system. The comet has intrigued astronomers due to its origin outside the solar system. Observations have been crucial in determining its trajectory and composition, particularly after gases sublimated from the comet during its closest pass by the sun in October. Hubble provided detailed views of the comet's teardrop shape, while Juice, en route to study Jupiter's moons, captured images showing a coma and two tails. The comet will come within 167 million miles of Earth on December 19, posing no risk to the planet.
