View at EarthSky Community Photos. | Garth Battista was in New Yorkâs Catskill Mountains â at Manhattan Country School â when he caught the easy-to-see constellation Orion and the star Sirius (far left). Sirius is always easy to see. Itâs the skyâs brightest star. Orionâs Belt â the short, straight row of 3 medium-bright stars â always points to it. Thank you, Garth!
Although white to blue-white in color, Sirius might be called a rainbow star, as it often flickers with many colors. The flickering colors are especially easy to notice when you spot Sirius low in the sky.
