NASA and the Goddard Space Flight Center use the Hubble Space Telescope to watch the Wolf-Rayet star NaSt1 blow its outer layers. This star isn't exactly new - in fact its thousands of years old, and it was first discovered by humans several decades ago. What's strange about this star and what makes it newsworthy today is its unique pancake-shaped disk of gas. Normally a star such as this shows a couple of lobs of gas blasting from opposite sides. The disk surrounding this star is nearly 2 trillion miles wide.
