Hubble Captures Young Stars Changing Their Environments

Captured by Hubble, HOPS 150 and HOPS 153 exist within environments shaped by powerful forces. But these stars release energy that reshapes the space around them, carving out new paths in their cosmic neighborhoods as a reminder that transformation is possible and driven by persistence and light.

An area in the Orion nebula filled with dark, puffy clouds. On the image’s right side is a large area of clouds crossed by a dark bar. The region glows in red and whitish colors lit by a protostar within. At the other side a large jet of material ejected by the protostar appears to be made of thin, wispy, blue, and pink clouds. A couple of foreground stars shine brightly in front of the nebula.

This NASA/ESA Hubble Space Telescope image features the nearest star-forming region to Earth, the Orion Nebula (Messier 42, M42), located some 1,500 light-years away.
