How do massive stars—like the one in nebula N83B—shape their environment? This Hubble Space Telescope image has helped to decipher the complex interplay of gas and radiation of the star-forming region. It illustrates just how these massive stars sculpt their environment—by generating powerful winds that alter the shape of the gaseous nebula that surrounds them. Here, the star is blowing a glowing spherical bubble in the nebula. #Hubble #nebula #stars #StarFormation #winds Credit: NASA, ESA, Mohammad Heydari-Malayeri (Observatoire de Paris, France). ALT-TEXT: The background of space is black, dotted with pink stars randomly across the frame. The right half of the image is covered in a semi-transparent red haze, which is broken up by a dark, uneven dust lane at the bottom. At center-left is a large white star. It is surrounded by light red and dark red gas and dust in the shape of a large irregular circle, which is less transparent than the section at right. The circle is about a quarter of the size of the red at right. A smaller pink star appears next to the white star. Some background stars shine through this circle.
