The cryovolcanic "centaur" comet 29P/Schwassmann-Wachmann has erupted four times in less than 48 hours, becoming unusually ...

However, such analyses are challenging when studying fully formed comets like Hale-Bopp, and become even trickier as the ...

comet or interstellar object, including its surface composition, shape, and structure, and the composition of its gas coma and plasma environment. Exploring comets is the main way to learn about the ...

But you need to see it soon. The coma and long tail of comet Tsuchinshan-ATLAS, also called C/2023 A3 (Tsuchinshan–ATLAS), is ...

Above: Takaya Okada (Japan) observes Comet C/2023 A3 with his EVSCOPE2. In the background you can see the comet tracing its ...

As a comet gets closer to the sun, it heats up slightly. That causes the ice covering its nucleus to become a gas, creating a coma. This gas — and dust — from the coma trails behind the comet ...

Writing in the journal Nature Communications, an international team describe how 2I/Borisov’s coma - the nebulous envelope around the nucleus of a comet - polarised light at a higher rate than ...

Last year, another comet, 12P/Pons-Brooks, drew attention with similar explosions that gave it a horned shape, earning it the ...

and become even trickier as the comet approaches the sun, where it heats up and spews dust and gases into a giant glowing "coma." One of the main questions the new study's researchers have ...

It’s a long-period comet from the Oort Cloud, a sphere around the solar system that’s home to millions of comets. Astronomers think it loops around the sun once every 80,000 years. Its coma is ...
