For the first time in over seven decades, the Mount Everest-sized 'Devil Comet', officially known as 12P/Pons-Brooks, is making its way into the inner solar system and may be observable with the naked eye in the coming weeks. Its closest proximity to the Sun on April 21 is expected to make it most visible, particularly for those in the northern hemisphere, where it will reach optimal visibility by Sophie Jenkins

For the first time in over seven decades, the Mount Everest-sized 'Devil Comet', officially known as 12P/Pons-Brooks, is making its way into the inner solar system and may be observable with the naked eye in the coming weeks. Its closest proximity to the Sun on April 21 is expected to make it most visible, particularly for those in the northern hemisphere, where it will reach optimal visibility until mid-April.
Dr. Robert Massey, Deputy Executive Director at the Royal Astronomical Society, advises that while the comet may not dazzle in brightness, under optimal conditions-absence of moonlight, minimal light pollution, and clear skies-there is a chance to spot it without the aid of telescopes. He recommends using binoculars for a better view and suggests consulting smartphone apps or finder charts to locate this celestial body, which will appear as a small, greyish haze.
The comet, completing its orbit every 71.3 years, presents a rare observation opportunity before its next appearance in 2095. Named after Jean-Louis Pons and William Robert Brooks, the discoverers from the 19th century, 12P/Pons-Brooks has intrigued astronomers since its identification in 1812, with sightings dating back to the 14th century.
Its notable green hue, attributed to the presence of dicarbon molecules that absorb and reradiate sunlight, alongside a "horned appearance" characteristic of cryovolcanic comets, has heightened interest. These eruptions, caused by internal pressure from heating, contribute to its nickname, "Devil Comet."
For those eager to witness this once or possibly twice-in-a-lifetime event, gazing towards the west-north-west post-sunset is recommended.
