This is not a Comet, this is a Star.

Colossal tail trails dying star

The tail measures a massive 13 light years in length

A distant star that hurtles through space at extraordinary speeds has a huge, comet-like tail trailing in its wake, astronomers say.

The appendage, which measures a colossal 13 light years in length, was spotted by Nasa's Galaxy Evolution Explorer (Galex) space telescope.

The researchers said that nothing like it had ever been spotted around a star.

They believe the star, known as Mira, will help them to study what happens as stars meet their demise.

Mark Seibert, a co-author of the paper, which was published in the journal Nature, and a scientist at the Carnegie Observatories in Pasadena, said: "This is an utterly new phenomenon to us, and we are still in the process of understanding the physics involved."
