Kelly Lepo | JWST's primary mirror is made up of 18 hexagonal, gold-coated segments. A new blog post is out today from the team that keeps the mirror segments perfectly aligned so that they function as one big mirror. So far, everything is going great. The overall performance of the telescope is far better than expected, and the alignment needs fewer corrections than expected. https:// blogs.nasa.gov/webb/2024/11/08 /monitoring-webbs-mirrors-for-optimal-optics/ # JWST # NASA # Astronomy

David Meyer | "Webb’s NIRCam (Near-Infrared Camera) captured this detailed image of SN 1987A (Supernova 1987A), which has been annotated to highlight key structures. At the center, material ejected from the supernova forms a keyhole shape. Just to its left and right are faint crescents newly discovered by Webb. Beyond them an equatorial ring, formed from material ejected tens of thousands of years before the supernova explosion, contains bright hot spots. Exterior to that is diffuse emission and two faint outer rings. In this image blue represents light at 1.5 microns (F150W), cyan 1.64 and 2.0 microns (F164N, F200W), yellow 3.23 microns (F323N), orange 4.05 microns (F405N), and red 4.44 microns (F444W)." 1987A is an awesome thing... https:// webbtelescope.org/contents/med ia/images/2023/136/01H8Q0YNFRGYKJC8JM90V1WHSG # astronomy # supernova # 1987A # physics # NASA # JWST
