Comet 12P/Pons-Brooks, also nicknamed the “devil’s comet”, will very soon be visible from Earth. The phenomenon is rare: it only occurs approximately every 71 years.
The next time it will be possible to observe it will therefore be in… 2095. It is currently at the limit of visibility with the naked eye, it is better to equip yourself with binoculars or a telescope to appreciate the spectacle up close. To make sure you don't miss anything, you'll have to look to the northwest, towards the constellation Andromeda.
