The first mention of anything resembling a space station occurred in Edward Everett Hale’s 1869 “The Brick Moon”. The first to give serious, scientifically grounded consideration to space stations were Konstantin Tsiolkovsky and Hermann Oberth about two decades apart in the early 20th century. In 1929 Herman Potočnik’s The Problem of Space Travel was published, the first to envision a “rotating wheel” space station to create artificial gravity. Conceptualized during the Second World War, the “sun gun” was a theoretical orbital weapon orbiting Earth at a height of 8,200 kilometres (5,100 mi). No further research was ever conducted. In 1951, Wernher von Braun published a concept for a rotating wheel space station in Collier’s Weekly, referencing Potočnik’s idea. However, development of a rotating station was never begun in the 20th century.
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:
Moon in a Fire element (Aries, Leo or Sagittarius) will react directly and with enthusiasm to anything that they can pioneer or have a leading part in directing change or something new. Emotions driven by fire can be explosive, impatient and restless but will feel at home in having a mission and implementing action in getting things off the ground and aiming for a goal.
If you want to measure our solar system, how would you do it? This simplest way is to measure it in light years. For those not familiar with the term, a light-year is the distance that light travels in a vacuum in one year. This is because the distances between stars is so huge that it is otherwise very challenging to imagine them. A light year is exactly 9,460,730,472,580.8 kilometers. Putting this into real world distances, the Milky Way is approximately 100,000 light-years across.
