What do you mean by astronomical observation from moon surface vis a vis low earth orbiting observatory?
Asked in The Moon
What advantages would you have if you built an observatory on the lunar surface?
If you built an observatory on the lunar surface, there would be no atmosphere to battle in viewing what you needed to see. Therefore, as far as an observatory goes, one could see more due to the fact that the sky would be much more clear from the moon since it has no atmosphere than that of Earth, which does.

Space orbiting telescopes are found where?
Usually orbiting Earth, that is, in an orbit around Earth, but fairly close to Earth - a few 100 km. distance from Earth's surface, at most. Usually orbiting Earth, that is, in an orbit around Earth, but fairly close to Earth - a few 100 km. distance from Earth's surface, at most.

Asked in The Moon, Astronomy, Planet Venus
Why is it hard to observe Venus from Earth?
For most observers, Venus is always close to the Sun, and therefore can only be observed near the horizon, where atmospheric distortion is the greatest. The observation of its surface is impossible from Earth because of the dense clouds of sulfur dioxide and sulfuric acid that cover the entire planet. But orbiting robot probes have mapped its waterless surface using radar.

Is it better to make astronomical observations from the Moon's surface or from a low earth orbiting observatory?
One of the main reasons why there is a push to construct a base on the moon is because telescopic observations from the moon would be clearer due to the fact that there would be no interference from an atmosphere, as is experienced on the Earth. Answer Moon Answer The heavy mirror in a large telescope becomes distorted in a gravitational field when fixed on the earth, which would happen even on the moon with its reduced gravity. This reduces the quality of the image. Actuators placed under the mirror are used to minimise this effect in some large modern telescopes (called active optics, see reference). However, orbiting the earth in space the telescope mirror becomes weightless and these effects can be virtually eliminated. This simplifies the telescope design and the subsequent image quality should be improved. An orbiting telescope would also be cheaper to launch and service than one located on the Moon.
How are geographers able to determine direction on the surface of the earth?
Directions can be established by comparing the geographical coordinates of a location with those of another location. Determining direction Direction on the Earth's surface can be obtained by a compass (which points to the location known as the North Magnetic Pole) or by comparing the position of astronomical objects (the Sun and stars). The Sun generally rises in the east and sets in the west, and long observation has determined more precise directions based on the day of the year. The stars appear to drift only very slowly from their nightly positions. The most modern determiner of direction is the GPS receiver, which receives information from an orbiting satellite whose position is precisely known. These can indicate directional motion on the surface to within a tiny fraction of a degree.
What uses orbiting satellites to provide the location of any point on the earth's surface?
Asked in Latitude and Longitude
What is the longitude and latitude of astro signs and the planets?
The system of latitude/longitude is an imaginary matrix that's pinned to the Earth's surface, and was created in order to describe locations on the Earth's surface. The system used to describe the locations of astronomical objects in the sky is similar but separate, and is pinned to the imaginary dome of the sky. You may have noticed that the position of astronomical objects over the Earth's surface is constantly changing ... it only takes a few minutes to notice the change ... and that the positions of the planets change even among the rest of the astronomical objects.
