Astrophysically, dark matter's gravity accounts for multiple disparate observations. From individual, rotating galaxies to the large-scale cosmic web, the evidence supporting dark matter is overwhelming.
New methods directly reveal dark matter's presence more rigorously than ever before. When galaxies interact within clusters, stars get stripped out, emitting faint intracluster light.
This 'tracing' technique lets us see and map out dark matter as never before, offering superior insights through the advanced capabilities of JWST compared to previous technologies.
The technique has been successfully leveraged previously with Hubble, revealing unexpected features, but now JWST offers a superior scientific potential for mapping dark matter distribution.
