Orion, the Great Hunter of Greek mythology, dominates the winter sky. This constellation is among the easiest to recognize. It is full of young stars, dying stars, and many nebulae.
Betelgeuse, one of Orion’s “shoulders,” is a red supergiant star about 650 times bigger than the Sun. It shines with the brightness of tens of thousands of Suns.
Rigel, one of Orion’s “knees,” is a triple-star system made up of two smaller stars orbiting a blue supergiant. Rigel’s blue supergiant star has a short lifespan.
On February 15, the Moon passes across the upper part of the solar disk, producing a partial solar eclipse.
The eclipse will be visible only from southern South America and parts of Antarctica.
