The objects within galaxies have two basic types of motions: orbiting around the galaxy centre in a regular organized disc, or in orbits oriented at random without a clear direction of rotaiton. If we ...

Galaxies are collections of stars, gas, dust, and dark matter throughout the universe. Their size and scale can vary considerably. The Milky Way in which we live has 200 billion stars, which puts it ...

Subjective classification of galaxies can mislead us in the quest for the formation and evolution of galaxies since this is necessarily limited to a few features. The human mind is unable to ...

The James Webb Space Telescope’s first picture released to the public showed off thousands of galaxies. At first glance, the pinpoints of light shining in the blackness of space look like little stars ...

This image, taken with Hubble’s Wide Field Camera 3, features the spiral galaxy NGC 4680. Two other galaxies, at the far right and bottom center of the image, flank NGC 4680. NGC 4680 enjoyed a wave ...

Astronomers have applied artificial intelligence (AI) to ultra-wide field-of-view images of the distant Universe captured by the Subaru Telescope, and have achieved a very high accuracy for finding ...

The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports. The team has shown ...

Edwin Hubble, born November 20, 1889, made seminal observations in 1923 of the Andromeda Galaxy and a Cepheid variable, which significantly broadened the understanding of other galaxies and the ...

More than 85,000 Internet users have signed up to become galaxy inspectors as part of the Sloan Digital Sky Survey's "Galaxy Zoo" project - and you can, too. Inspectors go through a tutorial and click ...

The giant elliptical galaxy NGC 1052 (at left) dominates the cluster it's a part of, though many other large galaxies are present, such as the giant spiral NGC 1042. Nearby to these galaxies are small ...
