The Earth has undergone five significant mass extinctions over its 4.54 billion-year history, with the most recent, which wiped out non-avian dinosaurs, linked to the Chicxulub asteroid impact. Some extinction events may have astrophysical origins, such as supernovae or cosmic phenomena, but an intriguing hypothesis suggests life on Earth could have been seeded by an “interstellar gardener,” potentially resetting life when it becomes unfavorable.
Recently, interest has surged around the interstellar comet 3I/ATLAS, prompting questions from figures like Kim Kardashian. NASA confirmed that it’s the third known interstellar comet and posed no threat to Earth. Questions have arisen regarding its peculiar characteristics, such as its unusual orbit, gas composition, and acceleration that doesn’t fit standard cometary behavior.
Avi Loeb, who is deeply involved in studying 3I/ATLAS, emphasized the importance of timely data sharing among scientists, especially in light of a potential government shutdown affecting research. As 3I/ATLAS approaches Earth on December 19, 2025, ongoing observations will be critical to understanding its nature and origin.
Loeb’s observations include its retrograde orbit, unusual gas plume composition, and acceleration patterns. He argues for a scientific approach that prioritizes transparency and curiosity rather than preemptive conclusions.
