The interstellar comet 3I/ATLAS recently reached its closest point to the Sun, known as perihelion, around October 29-30. This event allowed scientists to study its composition and behavior. 3I/ATLAS is only the third interstellar comet ever discovered, following ʻOumuamua and 2I/Borisov, and has sparked significant interest in the scientific community.

Harvard astrophysicist Avi Loeb has reported that the interstellar object 3I/ATLAS has exhibited a number of anomalous properties that suggest it might be an extraterrestrial probe or form of alien technology. And new observations have emerged in the last few days. Loeb notes that as 3I/ATLAS swung closest to the Sun, it sped up on its own —a mysterious "non-gravitational acceleration." In plain terms, it's moving in ways that gravity alone can't explain.

Furthermore, 3I/ATLAS shone bluer than the Sun, an unusual trait for a comet, which typically appears redder. Loeb pondered: Could this color come from ionized gases, or —more provocatively— from something artificial, like an engine or light source within?
