 Here we are zooming in to take another look at A.G. Corina, as viewed by Hubble this past year. The expanding shell of gas and dust that surrounds the star is about five light years wide, which equals the distance from here to Proxima Centauri, the nearest star to our sun. The huge structure was created from one or more giant eruptions about 10,000 years ago that blew the star's outer layers into space. The expelled material amounted to roughly 10 times our sun's mass. A.G. Corina is known as a luminous blue variable. These are among the most massive and brightest stars known. This one is 70 times more massive than our sun, but shines with a million times the brilliance. They only shine for a few million years compared to the roughly 10 billion year lifetime of our sun. A.G. Corina is estimated to be just a few million years old.
