Hubble Captures Giant Star on the Edge of Destruction

A large white star in the middle of the image is surrounded by an envelope of translucent blue and red. Filaments of light appear to radiate from its center. Surrounding the translucent envelope that directly surrounds the star is a thick, cloudy red ring shining through a ring of blue, giving the red ring the appearance of having glowing purple splotches. The dark background is covered with tiny red, blue, and white stars.

Summary

Petulant Star Ejects Spectacular Bubble of Glowing Gases

The mighty blue giant AG Carinae is not your normal star. One of the brightest stars in our Milky Way galaxy, AG Carinae is sizzling hot, shining with the brilliance of 1 million suns. You would need super sunscreen if you lived in the star's vicinity. The star is up to 70 times heftier than our Sun and burning fuel at a ferocious rate.

Its opulence means that the mammoth star is living life in the fast lane. Pouring out so much energy takes a toll on the stellar behemoth. It is prone to convulsive fits, expanding in size like a hot air balloon and shedding its outer layers of material into space. One or more giant eruptions 10,000 years ago created the beautiful, expanding shell of dust and gas seen here. Stars like this one are rare: less than 50 reside in our local group of neighboring galaxies.

The Hubble Space Telescope snapped an image of this particularly large outburst to commemorate the 31st anniversary of the Earth-orbiting observatory's launch into space.
