Purple clouds rise into a starry night sky in this beautiful image.
B.G Boyd captured this photo in early August around 5 a.m. while gazing up at the night sky over Tucson, Arizona to witness the annual Perseid meteor shower. Sunlight has turned the dark sky a deep purple as revealed by the clouds in the foreground.
Sirius, the brightest star in Earth's night sky, is among the celestial objects visible in the image. Also known as the Dog Star or Sirius A, stargazers can locate Sirius by using the three stars of Orion’s belt, which point downward toward the star.
Open star cluster, the Pleiades, appears in the shot as well. The cluster, also known as M45, comprises 800 stars formed about 100 million years ago. The celestial object is located in the constellation Taurus approximately 410 light-years away from Earth. A light-year is the distance light travel in one year, or about 6 trillion miles (10 trillion kilometers).
