NASA Discovers The  Ton Ice Ball On Its way

Largest Comet-a 500-

NASA Announced On Tuesday

that the Hubble Space Telescope has discovered the largest comet ever seen, and it is truly massive.

The discovery of this star which has been nicknamed 'Earendel' sets a new benchmark for NASA as the star was formed in the first billion years after the Universe was formed.

The Nucleus Of The Comet

the icy object at its centre that does not include its tail—is estimated to be 80 miles across and weigh 500 trillion tonnes

C/2014 UN271

or comet Bernardinelli-Bernstein, is the name of the icy behemoth


Pedro Bernardinelli and Gary Bernstein, astronomers, discovered it in 2010.

Reseachers Have Only

recently been able to determine its exact size. This is partly due to the comet's distance from the planet Uranus, which is about 2 billion miles

It Is Also Because

comets are encased in a shell of gas and dust that forms their distinctive tails and shrouds their core.

Astronomers Led By

Man-To Hui of the Macau University of Science and Technology

Were Able To Seperate

the comet's core from its shell and reveal the size of its main body by combining computer models with Hubble's observations.

 David Jewitt, co-author of a study describing the discovery, said, "It's big and it's blacker than coal."
