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."
