Eye on the Night Sky
Sunday, April 12, 2026
Today:
To the left of Orion’s belt, the brilliant star in the southwest is Sirius, known as the Dog Star, and the brightest star in the sky. As it lowers closer to the horizon, notice that as it twinkles, it flashes many colors. Its light is bending on its way through our atmosphere, giving us pin-point glimpses of its spectrum or rainbow, one color at a time.
