| Star predicted to explode in 2022 | | If and when 2 stars in this binary system merge - as predicted - they'll increase in brightness 10 thousandfold, temporarily becoming a bright star in Earth's sky. | | | | Tonight … Contemplate the apex of the sun's way | | Our sun moves around the center of the galaxy, toward the star Vega. Astronomers call this motion the apex of the sun's way. One circuit - about 230 million years - is called a cosmic year. | | | Star of the week: Rigel | | Blue-white Rigel, in the constellation Orion, is one of the brightest stars in the night sky. It's about twice as hot, and 40,000 times brighter, than our sun. | | | | | |

| | Contemplate the apex of the sun's way | Look northwestward at nightfall now, toward the star Vega, and you'll be looking in the direction our sun travels around the center of the Milky Way galaxy. | | | |
