Massive 85-mile-wide frozen giant comet observed near Neptune using powerful telescope in Chile
A groundbreaking discovery was recently made about the largest comet ever observed hurtling toward the sun from the Oort Cloud in the outer reaches of our solar system.
Astronomers recently got a close-up look at the comet, known as C/2014 UN271, flying through deep space with the powerful Atacama Large Millimeter/submillimeter Array(ALMA) radio telescope in Chile.
The icy giant is 85 miles across and is more than 10 times the size of any known comet, according to the National Radio Astronomy Observatory (NRAO).
The NRAO reported that astronomers found that new observations from the comet showed jets of carbon monoxide gas erupting out from the comet’s solid icy core.
