Skywatchers should look to the heavens for a glimpse of a rare comet last seen when Neanderthals inhabited the planet.
Astronomers say the celestial spectacle will be at its best this year, and it is unlikely to be seen again after it leaves our skies to zip off into outer space.
WalesOnline reports the best day for sightings is expected to be February 1, when the comet will be closest to our world and at its brightest after it travels around the Sun for 20 days.
