The Orion Nebula has always been a very exciting object for study since there are so many different interactions between stars and dust and gas going on there. It is a star forming region which means stars are being formed and are evolving as we speak and it gives us a great chance to try to understand how our own Sun formed and evolved. The reason we see X-rays within the Orion nebula is because of the interaction between the material surrounding many of the young stars and their magnetic fields. Since the Orion nebula is a star forming region, it contains many Young Stellar Objects or YSO's. YSO's come in the form of protostars and T-Tauri stars where a protostar will eventually form into a T-Tauri stars. Most X-rays we detect come from the T-Tauri stars because protostars are too deeply embedded in gas and dust for the X-rays to escape. Astronomers are still trying to better understand the specific processes which produce the X-rays and how they are related to how the new star formed. There is some evidence that the X-ray activity is related to the star's rotation as well as interactions with its newly formed protoplanetary disk (a disk of dust and gas out of which a solar system could form). The study of new solar systems around other stars in a new and exciting science since it helps us understand how our planets formed and the odds of there being other Earth-like planets within our own Galaxy. Thanks for the great question!
