How Long Does It Take To Get To The Moon?
How long does each phase of the Moon last?
Could the moon ever cause a person to tan? And following that logic-train, if direct sunlight can cause people to tan—and even burn—then why not reflected sunlight? The actual answer is no. Skin produces melanin as a result of continued sun exposure. Ultraviolet rays are harmful; they can cause skin damage and even cancer.
A series of new animations by a NASA scientist show just how zippy — and also how torturously slow — the speed of light can be. Light speed is the fastest that any material object can travel through space. That is, of course, barring the existence of theoretical shortcuts in the fabric of space called wormholes and the ability to go through them without being destroyed. In a perfectly empty vacuum, a particle of light, which is called a photon, can travel , miles per second , kilometers per second , or about This is incredibly fast. However, light speed can be frustratingly slow if you're trying to communicate with or reach other planets, especially any worlds beyond our solar system.

Moonlight consists of mostly sunlight with little earthlight reflected from the parts of the Moon 's surface where the Sun 's light strikes. The intensity of moonlight varies greatly depending on its phase , but even the full Moon typically provides only about 0. The color of moonlight, particularly around full Moon, appears bluish to the human eye compared to most artificial light sources due to the Purkinje effect. Moonlight is not actually tinted blue, and although moonlight is often referred to as "silvery", it has no inherent silvery quality. The Moon's albedo is 0. Moonlight generally hampers astronomical viewing, so astronomers usually avoid observing sessions around full Moon.
