In Cepheus, there is a NGC 7822.

There are hot, young stars and pillars of gas and dust in the picture. The glowing star forming region lies about 3000 light-years away at the edge of a giant cloud. There are bright edges and dark shapes in this telescopic skyscape. Data from narrowband filters show emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red colors. The emission line and color combination have become well-known. The emission is powered by the hot stars. Their powerful winds and radiation sculpt and erode the denser pillar shapes and clear out the characteristic light-years across the center of the cloud. As the pillars are eroded away, any forming stars will be cut off from their star stuff. The field of view spans 40 light-years.

The young star Jet Mho 2147 is a young star.

This stunning ground-based image of stellar jets from the Gemini South Observatory was improved by laser guide stars and adaptive optics. There are two outflows from a young star. At an estimated distance of 10,000 light-years, it lies toward the central Milky Way and the boundary of the constellations Sagittarius and Ophiuchus. The star is obscured by a dense region of cold dust. The jets are still visible in the image even though the system is estimated to be about 5 light-years away. Precession is believed to be the cause of the apparent wandering direction of the jets. Part of a multiple star system, the young star's rotational axis would slowly wobble like a top under the influence of its nearby companions.
