Is it true that Long-period comets come from the Oort cloud?
Yes. Multiple reference and peer-reviewed sources state that long-period comets originate from the Oort cloud, including NASA's Oort Cloud facts page and Wikipedia's Oort cloud article. Several research papers describe long-period comets as coming from the Oort cloud, though some phrase it as a hypothesis.
