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.
AnswerMoon AnswerThe 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.

What color is Dysnomia?
Dysnomia, the moon of the dwarf planet Eris, appears to be a reddish color based on astronomical observations. This color may be due to the presence of organic compounds on its surface.
What did Thomas Harriot use the telescope for?
Thomas Harriot used the telescope for astronomical observations, specifically to study the Moon. He made detailed maps of the Moon's surface, documenting its craters and mountains. Harriot's observations were significant contributions to the field of astronomy during his time.
What is the astronomical definition of rille?
A depression on the surface that looks like a channel.
Why is The moon surface visible to an observer on earth?
Its surface is visible because of how AU's (Astronomical Units) it is away from the Earth.
How do they find out about the surface on mars?
They use robots. Yes. They also get data from orbiting spacecraft.

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.

What methods did astronomers use to study the entire surface of the moon?
Orbiting satellites.

When did NASA found the water on moon?
NASA announced the discovery of water on the moon in October 2020. This discovery was made through observations by the Stratospheric Observatory for Infrared Astronomy (SOFIA) telescope. The presence of water molecules was detected on the sunlit surface of the moon, challenging previous assumptions about lunar water distribution.
The planet closest to the sun to have satellite?
Venus has two artificial satellites orbiting it, radar-mapping the surface and gathering other useful information about its surface.
What evidence is there that this force also pulls on objects closer to the surface of earth?
Objects in free fall experience the same acceleration regardless of their mass, indicating that gravity affects all objects equally. Additionally, the weight of an object decreases as it moves away from Earth's surface, suggesting a gravitational force that weakens with distance. Finally, observations of celestial bodies orbiting Earth or falling towards it further support the idea that gravity interacts with objects at all distances from Earth's surface.
