I always wonder that internet is basically to the core connected computers/network etc.. but how does satellite internet work? Do they have some towers on earth that send signal to satellites?

Yep, these are called uplinks. They usually are a big dish rather than an antenna-like ‘tower’ to focus the signal in the satellite’s general area in the sky. Uplink = signal up
A downlink is a dish or antenna connected to your home device, or an internet service provider will have a big dish as theirs. Downlink = signal down
