Narrative:

The event of a cracked; co-pilot #2 side window occurred during climb out phase of flight around 21;000 feet. We were roughly around 20-25 miles northwest ZZZ. As we were climbing to 24;000 feet the entire side window cracked all over and made a loud popping noise. There was a shockwave feeling on my chest and I felt my ears pop as well. The best way to describe this is like going to a fireworks display show and feeling the shockwave and hearing a loud bang from the big 'boomer' type fireworks. The pilot sitting next to me in the left seat heard the noise as well and visually saw the windshield but didn't feel the pressure on his chest or ears like I did. The event nonetheless caused us to react accordingly. I donned my O2 mask and we [advised ATC] and began an expedited descent to land as soon as possible at the nearest airport; which in our case was ZZZ. Once we were at a safe altitude to sustain life without supplemental oxygen I removed my O2 mask. We safely landed in ZZZ without injury to crew or passengers; which there were 3 of them. I couldn't say what caused the window to crack like that but it's the first time I've seen anything like that happen in flight. It should be noted that cabin pressure was nominal and was climbing and descending on schedule as it normally would during the climb and descent phase of flight. No cabin pressure change occurred when the window cracked in flight. Another aircraft was flown in to ZZZ to recover the passengers and continue them on their journey.since it appeared to be a freak accident in flight to the window I couldn't say a suggestion to avoid recurrence of this event. Neither the captain nor I had any cas message or indication in flight that would prelude to the window cracking like it did. It was a learning experience however and did build more confidence to reacting to inflight abnormalities that one can't really train for and that it's important to keep flying the airplane number one; and number two safely and efficiently react and get the aircraft on the ground as soon as practical; which the 'cracked/shattered windshield' QRH says to do.

Title: CE-750 flight crew reported the First Officer's windshield shattered in flight; so the flight diverted to the nearest suitable airport.
