The James Webb Space Telescope observed 19 nearby face-on spiral galaxies in near- and mid-infrared light as part of its contributions to the Physics at High Angular resolution in Nearby GalaxieS ...

A team of astronomers studying the distribution of galaxies in nearby space has discovered something truly extraordinary: a ...

The universe teems with systems of two stars orbiting each other in a seemingly endless cosmic dance. Scientists have long hypothesized that one out of three massive stars in these binaries have their ...

Galaxies like our Milky Way grew through cascading mergers of smaller galaxies that began billions of years ago. The ancient ...

At approximately 100,000 light years in diameter, the Milky Way’s vastness and the broader, ever-changing dynamics of the cosmos defy any attempt to fully understand our home galaxy and its history.

Massive galaxies with active nuclei are not merely a stage between youthful galaxies that are birthing stars and dying galaxies, but rather they can exhibit periods of profuse star birth. The ...

An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a ...

Image of the irregular dwarf galaxy Sextans A, located at a distance of about 4 million light years from us, towards the edge of the Local Group, captured by the VST (VLT Survey Telescope), an Italian ...

According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull ...

The latest data release from the Sloan Digital Sky Survey (SDSS) includes observations revealing the internal structure and composition of nearly 5,000 nearby galaxies observed during the first three ...
