Summary Draft 1

From the webpage “Why stars look spiky in images from the James Webb Space Telescope” from The Verge (2022) tells us the reason why the stars look spiky. Two functions of the James Webb Space Telescope (JWST) contributes to why the star looks spiky in the images from JWST. It is due to the primary and secondary mirror and the distance between them. The JWST is a reflecting telescope, whereby a large primary mirror gathers the light and reflects it back to a smaller mirror. The shape of the primary will affect how the light is being reflected onto the secondary mirror where it will lead the light to the near-infrared cameras (NIRCam) and near-infrared spectrographs (NIRSpec) from James Webb Space Telescope (NASA, n.d). The near-infrared camera (NIRCam) is JWST’s primary imager capable of covering ‘wavelength range 0.6 to 5 microns’NASA (n.d). NIRCam can detect light from stars and galaxies in the early process of formation. The near-infrared spectrographs (NIRSpec) is an instrument that analyses the wavelength that is captured by the NIRCam from NASA (n.d).
