Harvard scientist Avi Loeb stirred debate by suggesting that the item is probably not fully pure and will even symbolize some type of “alien know-how,” citing numerous anomalies in its habits. Nevertheless, NASA formally classifies 3I/ATLAS as a comet, as mirrored within the newest photos it launched.
Because the comet strikes nearer towards its December 19, 2025, nearest method to Earth, a number of observatories have captured new photos.

Right here’s a have a look at the newest three:-
1. NASA’s Hubble House Telescope: A Clear View of the Nucleus
Hubble was among the many first to picture 3I/ATLAS shortly after its discovery, displaying a teardrop-shaped mud cocoon across the object. On November 30, Hubble reobserved the comet utilizing its Broad Subject Digital camera 3, when it was 286 million kilometers away.
The brand new picture exhibits background stars stretched into streaks, as Hubble tracked the comet’s fast movement. On the middle is a shiny white dot, representing the comet’s nucleus, surrounded by a glowing coma and a visual tail.
In keeping with Loeb’s evaluation, the coma now extends roughly 40,000 km, whereas the anti-tail reaches almost 60,000 km. NASA has not but launched the total knowledge set from this remark, which shall be essential for figuring out the composition of the fuel plume.
2. ESA’s Juice Spacecraft: Twin Tails Detected
On December 4, the European House Company (ESA) shared a brand new picture captured by its Jupiter Icy Moons Explorer (Juice) spacecraft utilizing its Navigation Digital camera (NavCam).
Taken on November 2, simply two days earlier than Juice’s closest method at 66 million km, the photograph reveals the comet’s glowing coma and hints of two tails.
The plasma tail—made from electrically charged fuel—extends towards the highest of the body.
A fainter mud tail, composed of tiny stable particles, stretches towards the decrease left.
ESA famous that full knowledge outcomes shall be out there in February subsequent 12 months, because the spacecraft is presently utilizing its fundamental antenna as a warmth protect, limiting knowledge transmission velocity.
3. Beautiful Beginner Picture from Namibia
A panoramic ground-based picture of 3I/ATLAS was taken on December 2, 2025, by beginner astronomers Gerald Rhemann and Michael Jäger in Farm Tivoli, Namibia. Utilizing a 12-inch telescope, they mixed exposures of 20, 6, 6, and 6 minutes to disclose wonderful particulars of the comet.
Loeb defined that the picture’s subject of view—75 by 110 arcminutes—corresponds to six.1 by 9 million kilometers on the comet’s distance of 280 million kilometers from Earth on that day.
With its closest method simply days away, 3I/ATLAS continues to ship extraordinary knowledge and visuals. As extra observations are available in, scientists hope to unlock much more clues about this uncommon interstellar customer—and whether or not it behaves like a typical comet or one thing fully completely different.
