Images from telescopes with segmented mirrors also exhibit diffraction spikes due to diffraction from the mirrors' edges. As before, two spikes are perpendicular to each edge orientation, resulting in six spikes (plus two fainter ones due to the spider supporting the secondary mirror) in photographs taken by the James Webb Space Telescope.

The Webb telescope's mirror is composed of 18 individual mirrors, each having a hexagonal rim, rather than the round rim typically used in telescopes. The six diffraction spikes from the rim along with the two horizontal diffraction spikes from the struts, for a total of eight diffraction spikes.
The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant , or faint for the Hubble Space Telescope . [ 9 ]
James Webb: Born in NC, schooled at UNC-Chapel Hill. ... A second star, barely visible at lower left along one of the bright star’s diffraction spikes, is the nebula’s source. It has ejected ...

Astronomers observed a close pair of black holes dancing around one another using the Hubble Space Telescope and Chandra X-ray Observatory.
The couple share Alexander and James, who were born in 2019 and 2020, and she is also mother to Albert from her first marriage, who was born in 2012. Gere said he had lived in New York most of his ...
