Interstellar Comet 3I/ATLAS Today: Tail, Radio Signal & Viewing Guide
Interstellar comet 3I/ATLAS has survived its close approach to the Sun, developed a prominent ion tail, and emitted its first detected radio signal. Its orbit was confirmed with help from a Mars spacecraft. New data strongly counters online speculation about an artificial origin. The comet is currently in Virgo, about 2.1 AU from Earth, visible only by telescope.
