Harvard astrophysicist Avi Loeb has observed a perplexing anomaly in the behaviour of 3I/ATLAS, the third interstellar object spotted in our solar system since 1I/'Oumuamua in 2017 and 2I/Borisov in 2019.
Unlike typical comets, which develop tails pointing away from the Sun due to solar radiation and wind, 3I/ATLAS has maintained a narrow jet pointing towards the Sun even after its trajectory was bent by 16 degrees at perihelion.
