This infrared image shows IC 417, an emission nebula that is energized by hot, massive blue stars. A cluster of young stars called ‘Stock 8’ can be seen at center right; the light from this cluster carves out a bowl in the nearby dust clouds, seen here as green fluff. Along the sinuous tail in the center and to the left, groupings of red point sources are also young stars. Image credit: NASA / JPL-Caltech / 2MASS.

The inset image zooms in on the gap nearest to the star, which is at the same distance as the Earth is from the Sun, suggesting an infant version of an Earth-like exoplanet could be emerging from the dust and gas. The additional concentric light and dark features represent other planet-forming regions farther out in the disc. Image credit: S.
