NASA Just Confirmed The Largest Comet Ever Detected, And It's Truly Gargantuan

The largest comet ever discovered has been traveling towards the Sun for over 1 million years,

its gigantic scale shines a light on the mysterious objects that make up one of the biggest structures in our Solar System.

In a new study, astronomers used the Hubble Space Telescope to confirm that the solid center of the giant comet C/2014 UN271 (Bernardinelli-Bernstein) is the largest comet nucleus ever detected. 

It measures a staggering 50 times larger than most known comets, at almost 140 kilometers wide (about 85 miles).

However, that strangely large size – or rather its apparent weirdness – may also say much more about us and our limited concept of comets.

C/2014 UN271 is one such object, and it stands to tell us much about the existence of the frozen 'pristine' masses that make up the Oort Cloud.

These are thought to have formed early in the inner Solar System, before being flung out to its outermost fringes by the gravitational effects of giant planets like Jupiter and Saturn.

This comet is literally the tip of the iceberg for many thousands of comets that are too faint to see in the more distant parts of the Solar System,
