Comet 3I/ATLAS reaches its closest point to the Sun today, facing a final test of Avi Loeb's 'alien ship' theory. Will it perform an impossible manoeuvre, or will science put the controversial claim to rest for good?

The interstellar object 3I/ATLAS has gathered significant scientific attention, and soon it will reach its closest point to the sun.

Other than being a ‘Trojan Horse’ alien spaceship set to release probes to study our planet, or crashing into Earth, neither of which are likely, it looks like Comet 3I/ATLAS is what it appears to be — a comet — although a somewhat unique one.

Comets Lemmon and SWAN are nearing Earth in a rare double cosmic treat. Where and what time can you see them? What to know.

A captivating interstellar wanderer, known as 3I/ATLAS, has become the focal point of global astronomical interest. Researchers are intrigued by its peculiar behavior, notably a tail that shifts direction unexpectedly.

"Comets are like cats. They both have tails and do what they want," said comet discoverer David Levy many times. Well, Comet C/2025 A6 (Lemmon) is proving his words true. Most comet-watchers thought that Lemmon would reach its brightest October 21 when it was closest to Earth.
