To find the answer to this question, you can start by conducting a search using reliable sources such as books, scientific journals, and reputable websites.
You could start by searching for information about Galileo and his observations of the moon using keywords like "Galileo telescope moon observations" or "Galileo moon features observed."
Once you have gathered information from various sources, you can analyze the data and summarize the observations made by Galileo. In this case, Galileo observed several features on the moon, but the most significant ones were:
B: Wide, dark areas and strange spots and ridges
Galileo's observations revealed that the moon's surface was not smooth, as previously believed, but rather consisted of uneven terrain with dark regions and irregular features. He noticed dark spots, now known as lunar maria, which are large, flat areas on the moon's surface. Additionally, Galileo discovered ridges and other formations, indicating that the moon was not a perfect sphere.
It is important to remember that Galileo did not find evidence of other life forms on the moon. His observations were limited to visual features of the lunar surface.
