CEERS-2112
most distant barred spiral galaxy
CEERS-2112 is one of the most distant barred spiral galaxies observed as of 2023. The light observed from the galaxy was emitted when the universe was only 2.1 billion years old. It was determined to be similar in mass to the Milky Way.
Observations
The galaxy is located in the Extended Groth Strip cosmological field and it was identified as a barred spiral galaxy thanks to the observations of the NIRCam instrument onboard the James Webb Space Telescope. These observations were made in June 2022 as part of the Cosmic Evolution Early Release Science (CEERS) survey and are publicly available for the general community.
Morphology
CEERS-2112 is a barred spiral galaxy, resembling the structure of the Milky Way. It presents a concentration of stars moving on very elliptical orbits in its central region, which appears as an elongated structure (stellar bar), from which two faint spiral arms develop. In the local Universe, about 70% of galaxies show this appearance, which is quite rare in the early Universe, where the percentage diminishes to about 5% at redshift z > 2.
Stellar mass
The galaxy has a stellar mass of 3.9 billion times that of the Sun, comparable with that of the Milky Way 11.7 billion years ago.
The public source identifies “CEERS-2112” as most distant barred spiral galaxy. This brief keeps that definition visible, then builds a research path around CEERS-2112, most and distant.
Why this record matters
A short description can identify a subject without explaining its stakes. For “CEERS-2112”, the useful work is to connect “most distant barred spiral galaxy” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q123556206. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2023 and 2022.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
