This image from Webb’s NIRCam short-wavelength channel shows the Orion Nebula, its stars, and many other objects in unprecedented high definition in the near infrared. Many of the young stars are surrounded by dense disks of gas and dust which may be forming planets. In other cases, those disks are being destroyed by the intense ultraviolet radiation and strong winds from the most massive stars in the region. Many of these photoevaporating disks are visible if you zoom into the image. Image credit: NASA / ESA / CSA / M. McCaughrean / S. Pearson.

Schematic representation of the tilted accretion disk model. The black hole spin axis is assumed to be straight up and down in this illustration. The jet direction points almost perpendicular to the disk plane. The misalignment between the black hole spin axis and disk rotation axis triggers the precession of the disk and jet.
