Stars come in many shapes and sizes. Our Sun, for example, is massive compared to Earth, but it's far from the largest or most impressive. Using the Hubble Space Telescope, NASA and the European Space Agency are able to observe many nearby stars and those surveys have helped scientists learn a great deal about how stars of all types are born, live, and die. In a new post on NASA's website, the space agency highlights Hubble's 31-year sightseeing campaign by targeting one of the brightest stars in the Milky Way, and it's downright beautiful.

The star, which is called AG Carinae, looks quite a bit different than our Sun, and that's because the two are only very distant cousins. AG Carinae is a type of star known as a luminous blue variable, a rare and massive type of star that is maintaining a delicate balance to prevent its total destruction. The image you see is a combination of exposures from Hubble that combine to reveal the unstable nature of the star, which is estimated to be 70 times as massive as our own Sun.
