Ripple effect 🌀 Seen here by Webb's Mid-Infrared Instrument (MIRI) is the galaxy M51, also known as NGC 5194. The gravity of its neighbor, the dwarf galaxy NGC 5195, is thought to be partially responsible for those prominent & distinct spiral arms! While MIRI brings out the web-like structure of the dust in the galaxy, NIRCam focuses more on ionized gas from newly formed star clusters. More: esawebb.org/images/potm2308c/
One of the brightest nebulae in the night sky is Messier 42, the Orion Nebula, located south of Orion’s belt. At its core is the young Trapezium Cluster of stars, the most massive of which illuminate the surrounding gas and dust with their intense ultraviolet radiation fields, while protostars continue to form today in the OMC-1 molecular cloud behind.
No tricks, just treats. 🎃 Treat yourself to the bewitching sight of barred spiral galaxy M83 — which comes alive with detail in this new image by the Webb telescope’s MIRI instrument.
