Whirlpool Galaxy Hubble NASA Center Picture

What later became known as the Whirlpool Galaxy was discovered on October 13, 1773, by Charles Messier while hunting for objects that could confuse comet hunters, and was designated in Messier’s catalogue as M51. Its companion galaxy, NGC 5195, was discovered in 1781 by Pierre M├ęchain, although it was not known whether it was interacting or merely another galaxy passing at a distance. In 1845, William Parsons, 3rd Earl of Rosse, employing a 72-inch (1. 8 m) reflecting telescope at Birr Castle, Ireland, found the Whirlpool possessed a spiral structure, the first “nebula” to be known to have one. These “spiral nebulae” were not recognized as galaxies until Edwin Hubble was able to observe Cepheid variables in some of these spiral nebulae, which provided evidence that they were so far away that they must be entirely separate galaxies even though they are seen close together

Only once since I began a twenty year fascination with Einstein's time/light theory have I heard from anyone connected to NASA who dared to address this fact to a sublimely ignorant public. He was hushed up in the slow lane with indifference and a public that couldn't tell you how the world can make it through the next decade without imploding. With a list of almost infinite problems how can we think of getting people out that far, much less plan for the return of our astronauts after 4000 generations of time. The GRAIL mission determined the internal structure of the Moon in great detail for nine months during 2012. Armed with this the new information, GRAIL astronomers were able to redefine the sizes of the largest impact basins on the lunar surface. What is the difference between a Lunar Eclipse and New Moon? They seem quite similar and there is often confusion between the two. A lunar eclipse happens twice a year whereas a new moon happens once a month. Here is further clarification:
