Story summary

Researchers observed cryovolcanism on the interstellar comet 3I/ATLAS.
As 3I/ATLAS approached the Sun, it sublimated, emitting gas and dust jets.
The study notes that 3I/ATLAS travels at 137,000 miles per hour and shares similarities with trans-Neptunian objects, with a composition that may include materials crucial for life's origins on Earth, and scientists are racing to study it before it departs next year.
