Astronomers detect "wobbling high-latitude jet" in comet 3I/ATLAS, according to a preprint paper. A new mutation of flu strain A (H3N2) is driving an increase in influenza cases and hospitalizations. Bears in central Italy are evolving to become smaller and less aggressive after interacting with humans, study finds.

Interstellar object 3I/ATLAS has grown a colossal, sunward anti-tail larger than the distance to the moon. Is this an unprecedented comet, or is Harvard's Avi Loeb right about a technological origin?

On July 1st, 2025, the third interstellar object (ISO) ever detected was seen making its way through our solar system. Shortly after being alerted by automated detection systems, astronomers at the European Space Agency (ESA) began using observatories in Hawaii,

With 3I/ATLAS just days away from making its closest approach to Earth, agencies around the globe are conducting the largest and most extensive planetary defense drill — with the goal of protecting ourselves against future threats from beyond.

Interstellar comet 3I/ATLAS shows a rare sun‑facing anti‑tail, raising concerns that survey telescopes miss exotic visitors

In the spirit of the season, the interstellar comet 3I/ATLAS is changing color as it leaves the sun behind — shifting from a reddish tint to a faint green glow. That visible change signals the comet is reacting to solar heat and releasing new gases in space, giving scientists fresh clues about what it is made of and how it behaves.

Harvard Professor Avi Loeb explains that alignments between interstellar object 3I/ATLAS and gamma-ray bursts are statistically expected, with a dozen coincidences occurring over 8,000 years of Solar System transit.
