A rare visitor from interstellar space, comet 3I/ATLAS, is about to make its closest approach to the Sun. On 30 October, it will reach perihelion, the point in its journey where it is nearest our star and expected to be at its most active.
But while this cosmic traveller heats up, sky-watchers on Earth will miss the show entirely. The comet is currently hidden behind the Sun, lost in its blinding glare.
