The Prawn Nebula is a large stellar nursery positioned within the constellation Scorpius, about 6,000 gentle years from Earth. Though the nebula stretches 250 light-years and covers an area 4 instances the dimensions of the complete moon, it emits gentle primarily in wavelengths the human eye can not detect, making it extraordinarily faint to earthbound viewers. Hubble’s gaze, nevertheless, exhibits a small part of the nebula right here in each seen and invisible infrared gentle, capturing dazzling element of the nebula’s construction, together with vibrant areas of glowing fuel.

The Prawn Nebula, also referred to as IC 4628, is an emission nebula, which implies its fuel has been energized, or ionized, by the radiation of close by stars. The radiation from these large stars strips electrons from the nebula’s hydrogen atoms. As the energized electrons revert from their higher-energy state to a lower-energy state by recombining with hydrogen nuclei, they emit power within the type of gentle, inflicting the nebula’s fuel to glow. In this picture, purple signifies the presence of ionized iron (Fe II) emission.

This Hubble Space Telescope picture was captured as a part of a survey of massive- and intermediate-size “protostars,” or newly forming stars. Astronomers used the infrared sensitivity of Hubble’s Wide Field Camera 3 to search for hydrogen ionized by ultraviolet gentle ionized by the protostars, jets from the celebrities, and different options.
