ATel #17571: Detection of comet 3I/ATLAS in radio wavelength during closest approach to Earth using uGMRT

www.astronomerstelegram.org

The interstellar comet 3I/ATLAS reached its closest approach to Earth on 19th December 2025, at a distance of about 1.8 AU. We conducted low-frequency radio observations of the comet using the upgraded Giant Metrewave Radio Telescope (uGMRT) Band-5 at a central frequency of 1239 MHz on the day of the closest approach and two days before and two days after. The preliminary data analysis suggests the successful detection of comet 3I/ATLAS on 17 and 19 December 2025, with a significance greater than 10σ with flux densities on 17 and 19th December of 3.86 ± 0.38 mJy and 0.81 ± 0.05 mJy, respectively. The comet was not detected on 21 December 2025.

We find that comet 3I/ATLAS was significantly bright before its close approach (17 December) and became considerably faint at the closest approach (19 December), followed by a non-detection afterwards (21 December).

This study represents a key step toward probing cometary radio emissions at meter wavelengths. The detection confirmed the presence of measurable radio continuum emissions, likely arising from dust-related emissions and/or plasma processes associated with the interactions between the cometary environment and solar wind. Detailed calibration, imaging, time-variability studies, and spectral line analyses, including a search for atomic HI emissions at 1420 MHz, are currently in progress. These analyses will place important constraints on the physical conditions of the cometary coma, including dust content and interaction mechanisms.

Further scientific results will be presented in a follow-up publication.

We thank the GMRT operations team for scheduling and supporting these observations. The GMRT is operated by the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research.

In two weeks, it makes the closest approach to Jupiter.

The "unlikely" interstellar comet was almost on the plane of the ecliptic.

The 3I/Atlas object will pass at the minimum distance from Jupiter in exactly 2 weeks.

On March 16, 2026, the last significant event in the busy life of the comet and the alien spacecraft, 3I/Atlas (aka C/2025 N1 ATLAS), is expected. The object will pass at a minimum distance from the largest planet in the Solar system, Jupiter. According to the latest available estimates, the two bodies will approach at a distance of about 53 million kilometers — an insignificant amount by the standards of space.

Passing at such a close distance from Jupiter is the final link in a chain of truly unique coincidences that abound in the orbit of 3I/Atlas and which, in addition to its interstellar nature, have attracted widespread attention. The main feature of this orbit is its amazing proximity to the plane in which the planets of the Solar system rotate. Whereas most distant comets and asteroids fly into the Solar System from a variety of angles (top, bottom, and side), 3I/Atlas follows a trajectory that lies almost exactly in the ecliptic plane. This allowed him to previously "visit" all four planets closest to the Sun — Mars, Venus, Mercury and Earth. The chances of such a match are no more than 5-10%. Even more "incredible", with a chance of only about 2%, will be the upcoming approach to Jupiter at a distance of about 50 million km. Combined with the interstellar nature of the wanderer who flew into the Solar System, the full probability of a combination of all these factors is so low that the possibility of a repeat of such an event is almost excluded. With a high degree of probability, such an object will remain the only one in the modern history of mankind. In any case, if an interstellar body with the same orbital features arrives at Earth again after a while, scientists will be the first to announce that aliens are flying to us, so incredible will be the second such coincidence.

Famous last words. And not because of any alien stuff. The low statistical chances of having that trajectory suggests that it was helped along the way by the companion star. A binary (especially a long‑period companion) is dynamically more efficient per encounter at disturbing distant interstellar comets, like the ones increasingly described as visitors to our solar system.

In catalogs and scientific books, 3I/Atlas, of course, will forever remain a comet, since no observations have allowed us to assert the opposite. Those who don't want to give up the dream of an extraterrestrial ship or probe don't have to. In the end, we all understand that if an extraterrestrial civilization capable of traveling between the stars and, consequently, ahead of us by centuries, or even tens of thousands of years, wanted to disguise an artificial object as a comet, it is difficult to imagine that it would not succeed.

Ahead of the 3I/Atlas lies the emptiness of space and oblivion. The object will no longer encounter any large bodies of the Solar System after passing by Jupiter. In July of this year, the body will cross the orbit of Saturn, in April 2027 - the orbit of Uranus, and in March 2028 — the orbit of Neptune. In all these cases, at distances of billions of kilometers from the corresponding planets. Inside the Solar System (if it's just a comet), 3I/Atlas will stay for about five thousand more years — that's how long it will take it to reach its outermost borders, to the far edge of the Oort cloud.

However, no one will see any of this anymore. Already this year, after crossing the orbit of Saturn, the celestial body will cease to be visible even to the largest telescopes. At this point, the mother alien ship will be able to safely take him on board)

Indeed, 3I/Atlas came from the direction of Sagitarrius which is the general area of where the brown dwarf was before its closest approach to the Sun.

More research coming out showing how unique the comet was. The article has too many failed theories not worth mentioning, but I'll quote interesting points which shows that this comet was a sign of something afoot or different in our modern times.

'Interstellar messenger' 3I/ATLAS could be nearly as old as the universe itself, James Webb telescope observations reveal

Researchers already knew from the comet's speed and trajectory that it was potentially the oldest comet ever seen.

In our modern age, at least.

Previous estimates put the comet's age at somewhere between 3 billion and 11 billion years old. The new findings further narrowed down the comet's age and origin by looking at isotope measurements taken by JWST when the comet flew past Earth in December 2025.

"They show that 3I/ATLAS isotopic composition is very different from solar system comets and suggest that it likely formed 10-12 billion years ago," Romain Maggiolo, a research scientist at the Royal Belgian Institute for Space Aeronomy who was not involved in the study, told Live Science in an email. "In other words, 3I/ATLAS formed in a stellar environment different from ours, not only somewhere else in space, but also at a much earlier time in the history of the Milky Way."

The authors of the new preprint looked at the ratio of isotopes, or versions of elements, in material outgassed by 3I/ATLAS. They found that the comet's water is more enriched in deuterium, a heavier hydrogen isotope, than any previously studied comet, while its ratio of carbon isotopes also exceeded levels normally seen in our solar system.

Comet 3I/ATLAS is only the third interstellar object ever recorded in our solar system. The space rock, which Hubble Space Telescope observations suggest is somewhere between 1,400 feet (440 meters) and 3.5 miles (5.6 kilometers) wide, zoomed into our solar system at around 137,000 mph(221,000 km/h) last year before slingshotting around the sun.

The Cs said it was 8 km wide. We'll find out in a couple of days what a 8 km wide comet does in interaction with Jupiter, as comet 3I Atlas makes perihelion with the giant planet.

Finding those puzzle pieces is a race against time for astronomers, as comet 3I/ATLAS is now hurtling out of the solar system. It's currently passing Jupiter, where it is expected to make its closest approach on Sunday (March 15). The comet will come within about 33 million miles (54 million km) of the gas giant — much closer than it got to Earth.

Yesterday, I went outside with my stargazing binoculars to see Jupiter on a completely clear sky. I was regaled with my very own Galilean moment when I spotted Jupiter's four moons at twilight. It looked like a necklace of pearls It was Io, Europa, Callisto and Ganymede. 3 to the left and 1 to the right of Jupiter. It was heavenly!

Let's "finish" this thread with a bit of Russian humor. Perihelion is happening right now, as I write this post.

The latest significant event in the eventful life of Comet 3I/ATLAS—its closest approach to Jupiter, the largest planet in the Solar System—will occur today at 3:20 p.m. Moscow time. According to calculations by NASA JPL, the celestial body will pass within 53.6 million kilometers of the gas giant, which is a vast distance by Earth standards, but represents an exceptionally close (and in a sense, almost unbelievable) flyby by the standards of the Solar System.

The celestial body’s current speed exceeds 65 km/s. There is no possibility of catching up with and intercepting an object with such parameters. The only thing we can hope for is that in 100 or 200 years, if humanity has mastered sublight speeds by then, it will send a research probe in the direction where the celestial visitor will disappear, catch up to it, and definitively determine its nature. Or it might not find it at the calculated location, which in a sense would also determine the nature of the object, even more definitively.

Within the Solar System—if we consider the Oort Cloud to be its boundary—the celestial body will remain for another 10,000 years or so, although, as previously reported, it will completely disappear from the field of view of modern tracking systems in the second half of this year.

There have been no reports from NASA regarding any attempt to obtain the latest images of 3I/ATLAS using the Juno spacecraft, which is currently operating near Jupiter. However, the satellite’s optical instruments are not designed for this type of imaging, so the results would have been disappointing anyway and would only have fueled new suspicions of a cover-up. However, it is not out of the question that such images will eventually be taken—it is worth waiting to see.

Answers to the questions raised in connection with 3I/ATLAS’s transit past Jupiter, particularly regarding the possibility of probe deployment (within the extraterrestrial theory), will not be obtained under any scenario. It is impossible to make out anything of the sort from either Earth or Juno, so all sides will stick to their positions. Overall, there is currently an objective decline in interest in the celestial body. Therefore, as the object moves further away from Earth, it seems everything will come to an inevitable reconciliation along the lines of “we’ll never know anything anyway.” For now, let’s just wave goodbye to the comet. If, at that moment, you imagine that you’re waving to an alien probe or spacecraft flying away from Earth, that’s fine—it’s okay.

Of intesrest is the reality that we don't have the technology to study these comets beyond a specific range. Any claims that we know for sure what is lurking out there in "the immediate neighborhood", is wishful thinking.

The comet cluster is probably an exception if the largest comet there is about the size of dwarf planet Ceres (900 km).

According to Deepseek calculations this comet alone can be spotted decades before it arrives and there may be many more similar sized comets in the cluster.

It is basically no different than the discoveries of dozens of even smaller dwarf planets beyond Pluto (which are not being hidden).
