City-size comet headed toward Earth ‘grows horns’ after massive volcanic eruption

An uncommon volcanic comet flying towards the solar seems to have “grown horns” after it exploded, inflicting it to shine like a small star and bathe supercold “magma” into house. It’s the first time this comet has been seen erupting in virtually 70 years. 

The comet, named 12P/Pons-Brooks (12P), is a cryovolcanic — or chilly volcano — comet. Like all different comets, the icy object is made up of a stable nucleus, crammed with a mixture of ice, mud and fuel, and is surrounded by a fuzzy cloud of fuel known as a coma, which leaks out of the comet’s inside. However in contrast to most different comets, the fuel and ice inside 12P’s nucleus construct up a lot that the celestial object can violently explode, taking pictures out its frosty guts, often known as cryomagma, by means of giant cracks within the nucleus’s shell.
