On June 27th in the world of astronomy, one of the most exciting events occurred back in 2018. On this date, astronomers announced the discovery of complex organic molecules in the plumes of Saturn's moon Enceladus. This finding was made possible by data collected from NASA's Cassini spacecraft during its epic 13-year mission exploring the Saturnian system.

The discovery of these organic molecules, specifically large, carbon-rich compounds, was a groundbreaking moment in the search for potential life beyond Earth. Enceladus, with its subsurface ocean and hydrothermal vents, suddenly became one of the most promising candidates for hosting extraterrestrial life in our solar system.

Imagine the excitement in the scientific community! Astronomers and astrobiologists around the world were practically doing cartwheels in their observatories. The water-rich plumes shooting out from Enceladus's south pole were found to contain molecules with masses above 200 atomic mass units - much larger and more complex than previously thought possible.

This discovery led to a flurry of new research proposals and heated debates about the possibility of microbial life thriving in the warm, dark depths of Enceladus's global ocean. Some scientists even joked about renaming Enceladus to "Enceladus Prime" or "Life-celadus" in light of its newfound status as a prime astrobiological target.

The finding also sparked renewed interest in developing missions to explore icy moons, with some enthusiastic researchers proposing wild ideas like submarine probes to dive into Enceladus's subsurface ocean. While these ambitious plans are still in the realm of science fiction, the discovery on June 27, 2018, certainly fueled the imaginations of scientists and space enthusiasts alike.

So, as we look back on this date in astronomical history, we can't help but wonder: what other secrets might Enceladus be hiding beneath its icy surface? And more importantly, when can we go back for a closer look?
