…to ponder next time you want to see your problems from another perspective.






Antares is about 700 times the diameter of our own Sun, 15 times more massive, and 10,000 times brighter. Antares is the brightest star in the constellation of Scorpius and one of the brighter stars in all the night sky. Antares is seen surrounded by a nebula of gas which it has itself expelled. Radiation from Antares’ blue stellar companion helps cause the nebular gas to glow bright visible to us even though Antares is located about 500 light years away from earth. As you well know, a light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers. :))
