‘Messy’ galaxies in the early universe struggled to settle

Researchers used the James Webb Space Telescope to study young galaxies in the early universe, finding most were turbulent and 'clumpy'. Despite this chaos, galaxy dynamics show a gradual transition towards ordered structures, suggesting that galaxies like our Milky Way formed through frequent mergers and bursts of star formation.

Physicists explain a stellar stream’s distinctive features

Researchers found a core-collapsing self-interacting dark matter subhalo is responsible for the peculiar spur and gap features observed in the GD-1 stellar stream. This discovery provides insights into the nature of dark matter itself and offers a new explanation for the observed perturbations.

Introducing ‘UFO’ galaxies—the Milky Way’s dustier cousins

Researchers discovered a class of unusually large and red galaxies, called Ultra-red Flattened Objects (UFOs), near the limit of Hubble's observable range. The James Webb Space Telescope's infrared capabilities allowed them to spot these 'dustier cousins' of the Milky Way.

Galaxy changes classification as jet changes direction

Astronomers have discovered a galaxy with a unique activity in its core, leading to a reclassification as a giant radio galaxy. The PBC J2333.9-2343 galaxy has a blazar at its center with jets that changed direction drastically by up to 90 degrees.

Old and new stars paint very different pictures of the Triangulum Galaxy

Researchers used the Panchromatic Hubble Andromeda Treasury Triangulum Extended Region — or PHATTER — survey to study the Triangulum galaxy. The team discovered two drastically different structures depending on the age of the stars, with younger and older stars having distinct distributions.

Hubble's ultraviolet views of nearby galaxies yield clues to early universe

Astronomers studied 37 nearby galaxies using Hubble Space Telescope images in ultraviolet light, finding that faraway galaxies may not be inherently odd-shaped. The survey suggests that astronomers are detecting the 'tip of the iceberg' of very distant galaxies, and that their shapes may be influenced by incomplete observations.
