The Hubble constant, a set number that connects a galaxy’s speed to its distance from Earth and tells us how fast the ...

An international team of scientists has unveiled the largest and most detailed map of the universe ever created using the James Webb Space Telescope, revealing nearly 800,000 galaxies stretching ...

A surprising pattern of spatial distribution was discovered in dwarf galaxies, whereby diffuse ones cluster more strongly than do compact ones — opposite to the trend seen in massive galaxies.

Astronomers have for the first time spotted two galaxies in the throes of a deep-space “duel.”Related video above: The dark energy pushing our universe apart may not be what it seems ...

Stitched together from thousands of snapshots, the map is called the COSMOS-Web field, and it reveals almost 800,000 galaxies stretching all the way back to the universe’s start. “Our goal was to ...

The James Webb Space Telescope's deepest view of a single target yet depicts spinning arcs of light that are galaxies from the universe's distant past, the European Space Agency said Tuesday.

The team found only a 2 percent probability that the galaxies will collide in the next five billion years. In slightly over half of the simulated scenarios, Andromeda and the Milky Way experience ...

The best one is magnitude 9.2 NGC 5466, a loose globular cluster of stars that are more than 12 billion years old. Keep in mind the universe is 13.777 billion years of age. The 60 or so galaxies ...

It's a common question because, for many years, astronomers have theorized that the two largest spiral galaxies in our cosmic neighborhood — our Milky Way and Andromeda (also called M31 ...

At first glance, this is a large galaxy cluster. Take another look, though, and the warped light from older, distant galaxies comes into view. The James Webb Space Telescope captured this stunning ...
