According to Jainism, yes, living beings can be born in different realms and celestial worlds, but this is not described in the same way as modern science’s “other planets.”

In Jain philosophy, the universe is divided into:

• Devaloka — heavenly realms
• Naraka — hellish realms
• Manushyaloka — human realm
• Tiryanchaloka — animal/micro-life realm

So, Jainism teaches that the soul can take birth in many different places within the universe according to its karma. However, going to another physical planet by a machine or travel as imagined today is not a central teaching of Jain scriptures.

In short:

• Different realms/worlds? Yes, according to karma.
• Space-travel to other planets as modern science means? Not specifically taught in Jainism.

If you want, I can also explain the Jain view of the universe and lok in simple language.
