The intricate features of the outflow, represented in a reddish-orange color, provide detailed clues about how young stars form and how their jet activity affects the surrounding environment. A chance alignment in this direction of the sky provides a beautiful juxtaposition of this nearby Herbig

Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear centres ignite and create heavy elements in their cores. After only a few million years (for the most massive stars), the material is blasted back into interstellar space where star formation can begin again.

This expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the supernova explosion that created this remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light 11,000 years to reach us. This sharp image from the James Webb Space Telescope shows the still-hot filaments and knots in the supernova remnant. The whitish, smoke-like outer shell of the expanding blast wave is about 20 light-years across. A series of light echoes from the massive star's cataclysmic explosion are also identified in Webb's detailed images of the surrounding interstellar medium.
