they face chikens in space suits and use ray guns on the moon so that's why the moon has ecrators.
I don't know but type it in on google search and keep looking it is much easier!
Since the beginning of astronomy. Astronomers are ALWAYS looking for new things.
To fully understand how craters are produced, I suggest you ask an expert. Astronomers could provide you with the answers you seek. However, astronomers don't seem to connect to answers.com, so you should search elsewhere to get the answer to your question. To get started, you should use a reliable search engine, such as Google.com to find out more about astrology and astronomers. I hope you find what you're looking for.
Astronomers have not yet made any findings regarding the possibility of life on Mars.
The Search for Extraterrestrial Intelligence (SETI) was officially established in April 1985 as a collaborative effort among scientists, astronomers, and researchers to search for signals or signs of intelligent life beyond Earth.
We can not answer your question because, stupidly, you have not told us what "them" are.

Astronomers, looking at deep space photographs of the Universe.
Scientists are looking for life by studying various indicators like water, organic molecules, and potential habitats on other planets or moons. They also search for biosignatures such as methane in the atmosphere or biomarkers in rocks for evidence of past or present life. Missions like the Mars rovers, telescopes scanning exoplanets, and upcoming missions to icy moons like Europa and Enceladus are all part of the search for life beyond Earth.
As such astronauts do not search for life. It is not quite as simple as looking a the window of a space station and seeing aliens going past. They can search for life by taking rock samples of planets and searching for bacteria but most of the search for life is done using telescopes to find radio waves being sent out by intelligent lifeforms. You could help this by joining the SETI program.
Uranus was observed deviating from its predicted orbit, leading astronomers to hypothesize the existence of an unseen planet exerting gravitational influence. This discrepancy prompted the search for Neptune, which was later discovered in 1846.
Astronomers have long been interested in the possibility of life on Mars because it is one of the most Earth-like planets in our solar system, with conditions that may have been suitable for life in the past. Discovering whether life ever existed on Mars could provide insights into the origins of life on Earth and the potential for life elsewhere in the universe. Additionally, understanding Mars' environmental history can help inform future exploration and the search for habitable conditions beyond our planet.
