The most chemically primitive galaxy in the early universe: clues to the mysterious origins of ultra-faint dwarfs
Peer-Reviewed Publication
This May brings a rare celestial treat, two full moons in one month! We’re exploring the science of space and how astronomy connects us through curiosity, discovery, and a shared wonder for what lies beyond.

An international team led by Associate Professor Kimihiko Nakajima of Kanazawa University has captured a rare look at the early universe. Using the James Webb Space Telescope (JWST *1) and the power of a gravitational lensing (* 2) in space, the team achieved a definitive characterization of LAP1-B, an ultra-faint galaxy from 13 billion years ago. Expanding upon initial detections, this new study utilized deep JWST spectroscopy to reveal a record-breaking low oxygen abundance (* 3) -- merely 1/240th that of the Sun. This chemically primitive state, coupled with an elevated carbon-to-oxygen ratio and a dominant dark matter halo, suggests that LAP1-B is the long-sought "ancestor" of the mysterious fossil galaxies found near our Milky Way today, providing a historic window into the earliest, most primitive stages of galaxy assembly.
A review paper by scientists from Imperial College London examined how sensor‑integrated suits and soft exoskeletons could replace traditional exercise hardware with lightweight, modular, and intelligent systems that provide real‑time monitoring, dynamic loading, and personalized training—all while fitting inside a cramped spacecraft.
The new research paper, published on Apr. 17 in the journal Cyborg and Bionic Systems, discussed the challenges of the outer space environment and the musculoskeletal health complications derived from prolonged exposure. The currently employed solutions to address these complications are discussed, along with their limitations and potential solutions.
