A new image from the International Gemini Observatory reveals the growing tail of comet 3I/ATLAS, an interstellar visitor to our solar system. Captured during a public outreach event, the comet's tail has become more pronounced as it approaches the sun, indicating increased activity. This comet, only the third known interstellar object, poses no threat to Earth. It is expected to make its closest approach to the sun in late October and will remain visible through September. The observation session allowed students to engage with astronomers, enhancing public interest in space science. As it journeys back into interstellar space, 3I/ATLAS serves as a reminder of the wonders of our galaxy.
