Hubble captures one of the brightest stars in our galaxy Today’s Video of the Day from NASA Goddard features one of the brightest stars in our galaxy, AG Carinae, surrounded by a glowing halo of gas and dust. 

The image of the giant star was captured by Hubble on the 31st anniversary of the telescope’s launch.

According to NASA, the expanding shell of gas and dust that surrounds the star is about five light-years wide, which equals the distance from here to the nearest star beyond the Sun, Proxima Centauri.

The massive structure was formed about 

10,000 years ago, when a series of outbursts blew the star’s outer layers into space. The material that was ejected is about 10 times the mass of our Sun.

Luminous blue variable stars like AG Carinae are among the largest and brightest stars known, and live only for a few million years.  The word galaxy comes from a  French and Medieval Latin from the Greek term for the Milky Way ‘milky (circle)’, named after its appearance as a milky band of light in the sky. Also In the astronomical wording, the capitalized word “Galaxy” is often used to refer to our galaxy, the Milky Way, to distinguish it from the other galaxies in our universe. The English term  is Milky Way. Therefore shown above The Hubble captures one of the brightest stars in our galaxy.
