Crab Nebula seen in different wavelength
May 15, 2017 · ESA/Hubble
This video starts with a composite image of the Crab Nebula. The image was assembled by combining data from five telescopes spanning nearly the entire breadth of the electromagnetic spectrum: the Karl G. Jansky Very Large Array , NASA’s Spitzer Space Telescope , the NASA/ESA Hubble Space Telescope , ESA’s XMM-Newton Observatory , and NASA’s Chandra X-ray Observatory .
The video dissolves to the red-coloured radio wavelength view that shows how the neutron star’s fierce wind of charged particles energise the nebula, causing it to emit radio waves. The yellow-coloured infrared image includes the glow of dust particles absorbing ultraviolet and visible light. The green-coloured Hubble visible-light image offers a very sharp view of hot filamentary structures that permeate this nebula. The blue-coloured ultraviolet image and the purple-coloured X-ray image show the effect of an energetic cloud of electrons driven by a rapidly rotating neutron star at the centre of the nebula.
