"Explosion Alters Devil Comet's Appearance, Turning it Green and Hornless"

The 'Devil Comet', also known as 12P/Pons-Brooks, has lost its iconic horns after a massive volcanic eruption. Astronomers have observed new characteristics in the comet, including a mysterious shadow and a rare green hue. The comet, which is cryovolcanic and has an icy shell, will make its closest approach to Earth in over 70 years next summer. The recent eruption caused the comet's coma to expand, but the distinctive horns were not visible. It remains uncertain if the horns will reappear in the future.

"Iconic 'Devil Comet' Transforms into Green Spectacle after Volcanic Eruption"

The massive "devil comet" known as Comet 12P/Pons-Brooks has lost its iconic horns after its latest volcanic eruption, but has gained a rare green hue and a mysterious shadow. The comet, a cryovolcanic comet with an icy nucleus, has experienced three major eruptions, each time expanding its coma and appearing brighter to astronomers. The absence of horns suggests that the eruption may have damaged the obstruction that caused their formation. Additionally, the comet's coma now exhibits a green coloration due to high levels of dicarbon, and a shadow is believed to be cast by the outflowing cryomagma. Comet 12P/Pons-Brooks is expected to make its closest approach to Earth in June 2023.

"Earth's Encounter with a Transforming 'Devil Comet' Sparks Alarm"

The cryovolcanic comet 12P/Pons-Brooks, nicknamed the "devil" comet due to its distinctive horns, is hurtling towards Earth and has undergone a major change in shape. The comet, three times bigger than Everest, has lost its horns and now has a mysterious shadow. It has also turned green, possibly due to high levels of dicarbon. The comet is expected to keep exploding as it gets closer to Earth but will not return until 2095.
