Light from the sun hits the moon on one side, resulting in the sliver of light we normally see from a waxing moon, and it also reflects off the Earth toward the moon, faintly illuminating the entire lunar surface. The bright light to the left is the planet Venus, which is currently slightly farther away from Earth than the sun. The blue star just above the moon is Dabih, which is more than 344 lightyears from Earth (meaning the light we see from that star now has taken 344 years to reach us.)
