How galaxies get their shapes and evolve is widely debated.

To better understand observations of the most distant galaxies, an international team of astronomers has built a sample of local galaxies which can be studied in much higher detail. In a newly published study they show how the amount of light that escapes from a galaxy is connected to its physical properties. The result has implication for how we interpret observations of galaxies in the early universe.

Not all galactic neighborhoods are under construction; some have gone quiet. A new paper sheds new light on the ongoing debate about the reasons why.

A light-bending cluster of galaxies 9 billion light-years away is NASA's Friday photographic gift to people who want to end the work week with deep thoughts.

A team of astrophysicists affiliated with multiple institutions in the U.S., one in Germany and one in Canada, has developed a new theory to explain the existence of odd, dark matter–free dwarf galaxies. In their paper published in the journal Nature, the researchers propose that a collision between two dwarf galaxies could explain the dark matter–free dwarf galaxies that have been discovered over the past several…

Lado Samushia, associate professor of physics in the College of Arts and Sciences, Kansas State University, is part of a collaboration studying the mysterious force behind the universe's accelerating expansion, referred to as dark energy.

Galaxies bigger than ours appear less than a billion years after the Big Bang.

The James Webb Space Telescope has captured two early galaxies that are much brighter than astronomers expected they would be. Read more. The post Bright, early galaxies surprise astronomers first appeared on EarthSky.

A research team of Chinese astronomers has recently discovered 1,547 compact galaxies in the LAMOST DR9, of which 1,417 are newly discovered and include a large sample of Green Pea, Blueberry and Purple Grape galaxies. This is the largest sample of new compact galaxies discovered at one time to date.

The NASA/ESA Hubble Space Telescope imaged these two overlapping spiral galaxies named SDSS J115331 and LEDA 2073461, which lie more than a billion light-years from Earth.

This Hubble Picture of the Week features a richness of spiral galaxies: the large, prominent spiral galaxy on the right side of the image is NGC 1356; the two apparently smaller spiral galaxies flanking it are LEDA 467699 (above it) and LEDA 95415 (very close at its left) respectively; and finally, IC 1947 sits along the left side of the image.

These new images from the NASA/ESA/CSA James Webb Space Telescope are part of the large, long-standing Physics at High Angular resolution in Nearby GalaxieS (PHANGS) project.

Scientists are finding record-breaking galaxies in Webb images that may have existed when the universe was less than 200 million years old. The post Webb reveals more record-breaking galaxies first appeared on EarthSky.

Delian Asparouhov, newly minted Founders Fund partner and co-founder of Varda Space Industries, is obsessed with speed. As a hobby, he's getting his pilot's license, hoping to eventually fly a fighter jet. On the ground, he prefers to listen to audiobooks at triple the normal tempo. And when he ...

Digital Science has reimagined the way in which research collaborations within universities can be visualized.

An evocative new image captured by the Gemini North telescope in Hawai'i reveals a pair of interacting spiral galaxies — NGC 4568 and NGC 4567 — as they begin to clash and merge. These galaxies are entangled by their mutual gravitational field and will eventually combine to form a single elliptical galaxy in around 500 million years. Also visible in the image is the glowing remains of a supernova that was detected…

ABSTRACT. The triggering mechanism for the most luminous, quasar-like active galactic nuclei (AGN) remains a source of debate, with some studies favouring trigg

We think of galaxies as ancient. Our own galaxy, the Milky Way, formed 13.6 billion years ago, and the James Webb Space Telescope has allowed us to peer back...

Scientists have made a whole bunch of surprising new discoveries using the James Webb Space Telescope recently. Now, a group of galaxies have been observed which researchers are claiming should not exist at all in their current state. The earliest and most massive galaxies ever found by NASA's teles...

Paris (AFP) – The James Webb Space Telescope has discovered the four most distant galaxies ever observed, one of which formed just 320 million years after the Big Bang when the universe was still in its infancy, new research said on Tuesday.The Webb telescope has unleashed a torrent of scientific di...
