I’m noticing 6 spikes like the James Webb telescope, so the diffraction of light is the same as Webb, 6 mirrors.
What can this do that Webb can’t?
From the ESA website:
“In the absence of Earth’s atmosphere, and with optics of the highest quality, the angular resolution of a telescope is determined by the size of its primary mirror. Since Euclid has a smaller primary mirror than the Hubble Space Telescope, it will resolve fewer fine details, but the image quality will be outstanding and the lower resolution will be adequate to achieve its scientific goals. The telescope and its optics are designed to deliver a large field of view and a stable image quality throughout the survey.”
