After a decadelong hunt, scientists have finally pinned down the distance to an ancient galaxy teeming with star formation, finding it to be among the farthest galaxies of this type yet known, ...

Here’s a hand-wavy attempt: a galaxy is a collection of stars, gas, dust and dark matter all held together by mutual gravity. At the lower end of the scale, some very small galaxies could be ...

The James Webb Space Telescope (JWST) has just pushed the boundaries of astronomical observation. A galaxy named MoM-z14 has been identified as the most distant object ever observed. This discovery, ...

When Brant Robertson saw a new measurement of the distance to a familiar galaxy, he laughed out loud. For more than a decade, the galaxy had been a contender for the most distant ever observed. In ...

When it comes to the Milky Way and Andromeda galaxies, there’s a whole “will they or won’t they” thing going on. In 2012 scientists published their results of Hubble Space Telescope observations ...

The most distant galaxy cluster yet has been discovered by combining data from NASA’s Chandra X-ray Observatory and optical and infrared telescopes. The cluster is located about 10.2 billion light ...

Our Universe consists of hundreds of billions of galaxies, and for nearby galaxies, distances are mainly measured by classical Cepheids and RR Lyrae (RR Lyr) stars. RR Lyr stars are pulsating variable ...

The Hubble Space Telescope has unveiled the faint glow of ESO 490-017, a dwarf irregular galaxy over 23 million light-years ...

(Nanowerk News) Our universe is around 13.8 billion years old. Over the vastness of this time, the tiniest of initial asymmetries have grown into the large-scale structures we can see through our ...
