I am new to Rust programming language. Can Rust be used to make operating system?
Philipp Oppermann has a blog series on doing just that: Writing an OS in Rust
Yes, Redox is an operating system written in Rust: https://www.redox-os.org/
Rust is well-suited to building the low-level parts of an OS. For another example, my microkernel Pebble is written entirely in Rust.
Here is the outline for an operating systems course: https://tc.gts3.org/cs3210/2020/spring/index.html
