City-size comet headed toward Earth 'grows horns' after
massive volcanic eruption
Story by Harry Baker • Yesterday 12:06 PM
An unusual volcanic comet flying toward the sun appears
to have "grown horns" after it exploded, causing it to
shine like a small star and shower supercold "magma"
into space. It is the first time this comet has been
seen erupting in almost 70 years.
The comet, named 12P/Pons-Brooks (12P), is a
cryovolcanic — or cold volcano — comet. Like all other
comets, the icy object is made up of a solid nucleus,
filled with a mix of ice, dust and gas, and is
surrounded by a fuzzy cloud of gas called a coma, which
leaks out of the comet's interior. But unlike most
other comets, the gas and ice inside 12P's nucleus
build up so much that the celestial object can
violently explode, shooting out its frosty guts, known
as cryomagma, through large cracks in the nucleus's
shell.
On July 20, multiple astronomers detected a major
outburst from the comet, which suddenly became around
100 times brighter than it usually appears,
Spaceweather.com reported. This increase in brightness
occurred when the comet's coma suddenly swelled up with
gas and ice crystals released from the comet's
interior, allowing it to reflect more sunlight back to
Earth.
As of July 26, the comet's coma had grown to around
143,000 miles (230,000 kilometers) across, or more than
7,000 times wider than its nucleus, which has an
estimated diameter of around 18.6 miles (30 km),
Richard Miles, an astronomer with the British
Astronomical Association who studies cryovolcanic
comets, told Live Science in an email.

Ridiculous. It's just a comet. It doesn't have "horns."
