NASA's James Webb Space Telescope Reveals Massive Star Clusters Form Faster Inside Galaxies
Researchers said the findings may also help scientists better understand how planets form around stars.

Astronomers Uncover the Vast Greater Pleiades Complex with 3,000 Hidden Stars
Astronomers analyzing Gaia and TESS data have discovered that the famed Pleiades is only the bright center of a much larger stellar complex containing over 3,000 stars. Spanning 2,000 light-years, this vast family reveals how young clusters form, travel, and disperse across the galaxy.

Ursa Major III May Be a Star Cluster, Not a Dark-Matter Dwarf Galaxy
Astronomers have long thought Ursa Major III, also called UNIONS 1, was a dark-matter-packed dwarf galaxy. But new simulations suggest it may instead be a compact star cluster bound by black holes and neutron stars. Located 30,000 light-years away, Ursa Major III contains just ~60 visible stars yet shows puzzlingly high stellar velocities. The new ...

Earendel: JWST Suggests the Most Distant Star May Be a Star Cluster
Earendel, the farthest object ever seen, was first thought to be a single massive star from the early universe. New findings from JWST suggest it may instead be a star cluster, with many stars grouped together. Scientists used gravitational lensing to spot Earendel, which made its light appear thousands of times brighter.

Gravitational Waves Reveal Black Hole Ancestry Through Spin Analysis
A study published in Physical Review Letters explores how gravitational waves reveal the ancestry of black holes. By examining 69 black hole mergers, researchers found that spin shifts indicate repeated collisions in dense star clusters. This insight supports models suggesting black holes grow through sequential mergers. Observatories like LIGO and...

Webb Telescope Confirms Planet-Forming Disks Last Longer in Early Universe
The James Webb Space Telescope has revealed that planet-forming disks around stars in the early universe lasted far longer than previously believed. By studying NGC 346, a star cluster in the Small Magellanic Cloud, Webb observed disks surviving for 20–30 million years, challenging current models. This discovery suggests that low-metal environmen...

Oldest Planetary Nebula Hosted by 500-Million-Old Galactic Cluster Discovered: All Details
The oldest visible planetary nebula has been discovered by astronomers inside a 500-million-year-old galactic open cluster. These planetary nebulas are glowing shrouds ejected from dying stars, which present a spectacular sight. Believed to be of high astrophysical value, the rare celestial jewel has been discovered inside a cluster called M37 and ...

Dazzling Diamond-Like Stars Perfect Visual Treat
NASA's Hubble space telescope has captured a glittering star cluster that resembles an opulent diamond tapestry, containing a collection of some of the brightest stars seen in our Milky Way galaxy.

Hubble Survey Unlocks Clues to Star Birth in Neighbouring M31 Galaxy
Astronomers have found that the neighbouring Andromeda galaxy and our own Milky Way have a similar percentage of new-born stars based on mass.

Astronomers Unlock Clues to Star Birth in Neighbouring Galaxy
After analysing images of 2,753 young, blue star clusters in the neighbouring Andromeda galaxy (M31), astronomers with the help from "citizen scientists" have found that M31 and our own Milky Way have a similar percentage of new-born stars based on mass.

Stars Found Forming at Milky Way's Outer Edge
Brazilian astronomers said today they had found two star clusters forming in a remote part of our Milky Way galaxy where such a thing was previously thought impossible.
