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)
