To be aware, although genuine photographs of the Earth viewed from the Moon exist, many from NASA, some photographs shared on social media, that are purported to be the Earth viewed from the Moon, may not be real.
Earth and the Sun sometimes meet in the lunar sky, causing an eclipse. On Earth, one would see a lunar eclipse, when the Moon passes through the Earth's shadow; meanwhile on the Moon, one would see a solar eclipse, when the Sun goes behind the Earth. Since the apparent diameter of the Earth is four times as large as that of the Sun, the Sun would be hidden behind the Earth for hours. Earth's atmosphere would be visible as a reddish ring. During the Apollo 15 mission, an attempt was made to use the Lunar Roving Vehicle's TV camera to view such an eclipse, but the camera or its power source failed after the astronauts left for Earth.
Solar eclipse shadows, when the Moon blocks sunlight to the Earth, on the other hand, would not be as spectacular for observers on the Moon viewing the Earth: the Moon's umbra nearly tapers out at the Earth's surface. A blurry dark patch would be barely visible. The effect would be comparable to the shadow of a golf ball cast by sunlight on an object away. Observers on the Moon with telescopes might be able to discern the umbral shadow as a black spot at the center of a less dark region (penumbra) traveling across the full Earth's disk. It would look essentially the same as it does to the Deep Space Climate Observatory, which orbits Earth at the L1 Lagrangian point in the Sun-Earth system, from Earth.
In summary, whenever an eclipse of some sort is occurring on Earth, an eclipse of another sort is occurring on the Moon. Eclipses occur for observers on both Earth and the Moon whenever the two bodies and the Sun align in a straight line, or syzygy.

Sailing (sport)
The sport of sailing is racing other boats around a track or course which is marked with floating buoys or other fixed marks. Boats can be from small dinghies to large yachts. Usually, the small boats will just race each other and be of the same type. This is called one-design racing. Larger boats will often be of different sizes and race with a handicap system.
On the water, a large sailing competition among different boats is a regatta. This is usually a number of races, where the boat crew that performs the best over the series of races is the winner. A lot of racing is done around buoys or marks in safe water near the shore but some longer offshore races cross open water.
It could be said that the sport of international yacht racing began with the America's Cup in 1851. A group of members from the New York Yacht Club built a 101-foot schooner which they called America. This yacht was sailed to England where it won a challenge race for a trophy called the Hundred Guineas Cup. The race course took them around the Isle of Wight. This trophy was subsequently renamed The America's Cup and remained with the New York Yacht Club until 1983. An Australian yacht called Australia 2 finally took it from them after 132-years.
There are a number of famous yacht races being held every year is different parts of the world. These are held using large yachts and involve racing for a number of days without stopping. It is a test of skill and strength over a long time.
Some of the most famous races are:
Several famous round-the-world races are held also and these are:
The oldest known one-design sailing dinghy is the Water Wag. In 1887 a Mr Thomas Middleton proposed the idea of one design sailing punts, with centreboards all built and rigged the same. A number of these were built and the first race took place on April 12, 1887, in Kingstown (now Dún Laoghaire) Harbour near Dublin in Ireland.
Now dinghy racing is a worldwide sport and holds events and championships in many classes every year.
This is done entirely in small boats known as keelboats and dinghies. A keelboat has a weighted keel to keep it upright and a dinghy just uses a centreboard and the boat must be balanced by the crew. These were divided into different groups of identical boats called Classes. The first sailing Olympics took place in 1900 at Meulan near Le Havre in France. Over the years the classes of boats allowed to compete have changed because of new design and technology.
Races are sailed in fleets of equal boats racing around the same course at the same time. These race courses include different sailing angles: upwind, downwind and reaching.
This is one boat against another over a short course. It is important that the boats are the same and it is the normal race now used for the America's Cup but it is also sometimes used for racing in yacht clubs.
The Racing Rules of Sailing are used for the sport of yacht racing, windsurfing, kitesurfing, model boat racing, dinghy racing and any other form of racing around a course with more than one boat while powered by the wind.
