Comets

An unusual "horned" comet is now visible in the night sky and may even make a rare appearance during the total solar eclipse on April 8, 2024.

The Solar and Heliospheric Observatory just hit a milestone with its 5,000th comet detection.

New, specially edited photos show a previously unseen swirl of light surrounding the city-size comet 12P/Pons-Brooks, which is currently racing toward the sun and will later zoom past Earth.

Researchers are calling on amateur astronomers to help photograph the broken tail of a comet on track to pass by Earth this spring.

Comet Wild 2 formed 4.5 billion years ago and is a relic of the birth of the solar system. In 2006, NASA brought pieces of it down to Earth.

On Friday, Dec. 8, Halley's Comet reaches its farthest point from the sun and begins its journey back through the solar system.

What is causing the structure of the dust to evolve, and where exactly the dust comes from, is still a mystery.

The exact cause of 'Devil Comet' 12P/Pons-Brooks' flare-ups is unknown, though the best guess is that perhaps a fissure has developed on the comet's nucleus due to a build-up of gas.

An icy volcanic comet that is three times as large as Mount Everest, nicknamed the "Devil Comet," erupted again Nov. 14. This is the fourth explosive event for 12P/Pons-Brooks since July 2023.

Scientists suspect that comets may have delivered the key ingredients for life on Earth, and new research outlines how exoplanets could have received these deliveries, too.
