The smallest, reddest galaxies in this image may be among the most distant known, existing when the universe was just 800 million years old. Hubble’s powerful vision snagged a view of the galaxies by taking a very deep exposure of the sky, staring at the HUDF area for more than 11 days. The images taken with the Mid-Infrared Instrument, also called MIRI, provided a clear, sharp view of a faint halo outside the ring. Way Galaxy can be seen in ground-based images. The team believes the spikes are from molecules that form in the dense shadows of the ring. Outside of the ring are prominent spiky features that point away from the dying star, which glow in infrared light but were only faintly visible in previous images taken by the Hubble Space Telescope. “The bright iconic ring structure of the nebula is composed of about 20,000 individual clumps of dense molecular hydrogen gas, each of them about as massive as the Earth,” Wesson wrote. Wesson and his international team called ESSENcE, which stands for the Evolved StarS and their Nebulae in the JWST Era, used Webb’s Near-Infrared Camera and Mid-Infrared Instrument to capture unprecedented details that could help them understand more about how planetary nebulae evolve over time. The image has undoubtedly captured the minds of amateurs and. “It begs the question: how does a spherical star create such intricate and delicate non-spherical structures?” The Hubble Ultra Deep Field displays nearly 10,000 galaxies across the observable Universe in both visible and near-infrared light. “As a last farewell, the hot core now ionizes, or heats up, this expelled gas, and the nebula responds with colorful emission of light,” wrote Roger Wesson, an astronomer at Cardiff University, in a NASA blog post about Webb’s latest observations of the Ring Nebula. The Ring Nebula was created as a dying star, called a white dwarf, began shedding its outer layers into space, creating glowing rings and expanding clouds of gas. This view of nearly 10,000 galaxies is the deepest visible-light image of the cosmos. Some nebulae are stellar nurseries where stars are born. Messier and astronomer Darquier de Pellepoix discovered the Ring Nebula in 1779. Planetary nebulae, which have nothing to do with planets despite the name, usually have a rounded structure and were so named because they initially resembled the disks from which planets form when French astronomer Charles Messier discovered one for the first time in 1764.
