Early Universe Clues Found Locally

A portion of the dwarf galaxy Wolf–Lundmark–Melotte (WLM) captured by the James Webb Space Telescope’s Near-Infrared Camera. The image demonstrates Webb’s remarkable ability to resolve faint stars outside the Milky Way. Color translation: 0.9-micron light is shown in blue, 1.5-micron in cyan, 2.5-micron in yellow, and 4.3-micron in red (filters F090W, F150W, F250M, and F430M). Credit: NASA, ESA, CSA, Kristen McQuinn (RU); Image Processing: Zolt G. Levay (STScI) There are two ways to go digging for ancient relics in our universe. You can use a telescope like the JWST to look at the light from...

Black Holes Formed Before Stars

Black Holes Formed Before Stars

An illustration of a magnetic field generated by a supermassive black hole in the early universe, showing turbulent plasma outflows that help turn nearby gas clouds into stars. New findings suggest this process might be responsible for accelerated star formation in...

Unexpected Galaxy Photobombs Cluster

Unexpected Galaxy Photobombs Cluster

A color-composite image of PEARLSDG made with JWST NIRCAM data. Individual stars are visible as small points of light in the image. Its somewhat dull color and lack of many bright stars is consistent with its old age and lack of ongoing star formation. Credit: Image...

Quasars Spotted Blowing Away Gas

Artist’s impression of an outflow of molecular gas from the quasar J2054-0005. Credit: ALMA (ESO/NAOJ/NRAO) Gas dynamics are more than a little complicated no matter where you look. The dynamics of gas in and around forming galaxies makes is particularly...

Explaining Early Bright Galaxies

A composite of Stephan’s Quintet, a visual grouping of five galaxies, constructed from almost 1,000 separate image files from the James Webb Space Telescope. UCLA astrophysicists believe if cold dark matter theories are correct, the Webb telescope should find tiny,...

Gas Ripples Shake Up Ancient Galaxies

FIR image of BRI 1335–0417 overlaid with our identified bar ellipses (blue ellipse) and two-armed spiral structure identified in Tsukui & Iguchi (2021, black solid line). Contours start at 2σ but are logarithmically spaced in powers of 2 (2σ, 4σ, 8σ,...)....

One Theory Puts Us Somewhere Special

The image shows the distribution of matter in space (blue; the yellow dots represent individual galaxies). The Milky Way (green) lies in an area with little matter. The galaxies in the bubble move in the direction of the higher matter densities (red arrows). The...
