There have been many significant developments in astronomy. If you are asking about the two most important, then I suggest you consider the development of the telescope by unknown opticians in Belgium, and the wide adoption of the Copernican theory of a Sun-centered solar system.
There are a number of other developments that are probably almost as important; perhaps some of the other folks here can suggest some.
Babylonian astronomy was important in terms of the functioning of the state and for the king. Celestial phenomena were tracked and recorded, as well as events that happened on Earth that corresponded with those phenomena. In doing so, Babylonian astronomers created a respotiory of known omens, so that the king could take action against whatever the sky predicted would happen. They were able to create an accurate astronomical table so they could know what was happening in the sky even if it was obscured and were also able to notice when something happened in the sky that was out of the ordinary or against know patterns.
We'll make you a deal: instead of just typing your homework questions in verbatim, spend half a minute thinking about what kind of information we'd need to have to answer it (hint: it would help if we knew what "these cultures" were), and then we'll consider actually answering you.
Babylonians excelled in astronomy and math.
One I know is the invention of the telescope
They were the first to divide a circle into 360 degrees so that angles could be measured, and they made the first recorded observations of things in the sky.
Newton theoretically and Hubble observationally( natural experiments).
every culture has made some contribution to astronomy.
Newton's Theory of Gravity and Newton's Reflective Telescope are two major achievements in astronomy.
Babylonians:)
People who made important contributions to our knowledge of astronomy include Kepler, Galileo, Bruno (Giordano Bruno), Einstein, Lemaitre, Zwicky, Hubble... And a host of others. You can find many more names, for instance, if you check the Wikipedia article on "History of astronomy".
what contributions have the Seneca tribes made to our nation today
That's a really hard one to answer. If you are talking about historical or "famous" figures in astronomy, it would depend on the list provided. If you are talking about who made the latest contribution in general, well there are tons of papers constantly being published, so it will change frequently.
There are no problems faced by multiculturalism. Multiculturalism encourages racial and ethnic harmony. How can educating people on accepting another culture and being made aware of the contributions to our nation from ALL cultures cause a problem? I feel that the only problems facing multiculturalism, are the people who do not believe in it and who do not embrace what it stands for.
Asia had more contributions than Africa because they made mush more thing and was better for the country,
She made contributions to astronomy, philosophy, & mathematics.
Since human beings first looked into the skies, during the daytime and particularly at night, there has been astronomy. Many major figures from ancient times through to the present day have made contributions to astronomy.
Babylonians
The four main indigenous cultures that have made major contributions to the population of South America are the Inca, Maya, Aztec, and Guarani peoples. These cultures have left lasting legacies in terms of art, architecture, language, agriculture, and cultural practices across the region.

the possiblility of traveling to other galaxys
Many contributions were made by Chinese and Islamic astronomers to modern day astronomy, including the trigonometric methods created to determine the precision of dates, and supernova research.
Most cultures have significant aspects of astronomy present in them, as it was a primary method for telling time and planning crops around the world. Chinese history has some of the earliest recorded accounts of comets and even a supernova. Greek astronomers, through their ties with the rise of the Roman Empire, have had many of their constellations adopted by the western powers. They also have the earliest estimate for the diameter of the earth (which they determined to be round long before that!) at ~300 BC. Mayans and Egyptians have extensive calendar systems, though their impact on modern astronomy (again, in the western hemisphere) is minimal.
The indigenous cultures of Mesopotamia included the Sumerians, Assyrians, and Babylonians. Each culture had its own unique language, religion, and social structure. They developed sophisticated systems of writing, created monumental architecture, and made significant contributions to mathematics, astronomy, and literature.
Hypatia is remembered for her contributions in the field of mathematics and philosophy. She was a renowned scholar and teacher in the city of Alexandria in late antiquity, where she made significant advancements in geometry, astronomy, and Neoplatonism philosophy.
