Extragalactic Archaeology tells the 'life story' of a whole galaxy

Mergers, Mayhem, and the Milky Way

Galaxies grow through mergers and collisions, and astronomers want to know more about the mergers in the Milky Way's past. But mergers can stir up the stars in the resulting galaxy...

See and hear galaxies evolve from the dawn of the universe

The most realistic picture yet of how galaxies formed and then evolved from the beginning of time has been revealed in a suite of new and unique audiovisual simulations. These data...

How Massive Star Clusters Shape Galaxy Evolution

A team of researchers used the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope to observe almost 9,000 star clusters in four nearby galaxi...

ALMA and JWST investigate giant disk galaxy's formation and evolution

European astronomers have used the Atacama Large Millimeter Array (ALMA) and the James Webb Space Telescope (JWST) to observe a recently discovered giant disk galaxy known as ADF22...

Galaxies Don’t Die All at Once

State-of-the-art simulations shed light on how galaxies die — and how we can determine the cause of death. The post Galaxies Don’t Die All at Once appeared first on Sky & Teles...

Gravitational lens shows a galaxy just 800 million years post-Big Bang

Early galaxy has elements produced by the Universe's first supernovae.

Astrophysicists use 'space archaeology' to trace the history of a spiral galaxy

Billions of years ago, a young spiral galaxy began to grow in a crowded part of the universe. It pulled in gas and small companion galaxies, slowly building up the bright central r...

Hubble Capture a Starry Spiral Cosmic Neighbor

A spiral galaxy seen close up and tilted at an angle, so that its disc fills the view from corner to corner. Its disc is yellow near to the centre and pale blue farther out, showin...

DECam's New Image of the Sombrero Galaxy: A Portrait of Ancient Mergers

The 570 megapixel Dark Energy Camera captured this image of the iconic Sombrero Galaxy. The galaxy has characteristics of both elliptical galaxies and spiral galaxies, and is likel...

Why were galaxies so active in the early universe? We may be getting close to the answer

Early galaxies were star-forming machines, gobbling up gas and spitting out stars with a furious intensity. A new model helps explain why things were so different back then.

Synthetic universe allows you to 'see and hear' galaxies evolving from the dawn of time (video)

Scientists have used a synthetic universe to observe how the first galaxies evolved and grew. In fact, it is so close to the real thing that it's tricking some astronomers.

Ultra-Faint Dwarf Galaxies Could Unlock Secrets of the Early Universe

Tiny galaxies orbiting the Milky Way may hold clues to one of cosmology’s biggest mysteries. Ultra-faint dwarf galaxies are among the smallest known galaxies orbiting the Milky Way...

A Galaxy Cluster's Wild Youth

The galaxy cluster Abell 2029 is sometimes described as “the most relaxed cluster in the Universe.” This moniker does not arise from some sort of mellow vibe, but rather because of...

New James Webb Space Telescope images reveal how massive star clusters can reshape galaxies

The James Webb Space Telescope has helped scientists peek into the secrets of galactic evolution — and the view is stunning, too.

Hubble reveals rare galaxy 100 million light-years away caught in transition

This NASA Hubble Space Telescope image reveals an enigmatic galaxy with a bright center and a face that hints at spiral structure, yet it holds no obvious spiral arms. Reddish-brow...

Image: A gently glowing galaxy

A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this NASA Hubble Space Telescope image from April 13, 202...

Local dwarf galaxies may preserve a record of the infant Universe

Ultra-faint dwarf galaxies orbiting the Milky Way are cosmic fossils. New simulations reveal how these tiny systems reflect early Universe conditions and why some galaxies grew whi...

How a single star can reshape an entire galaxy

Astronomers who simulate galaxies do not always get the same result, even when they start from identical conditions. New research from Leiden University shows that this is not a fl...

Gazing Into the Past With TIME

How can astronomers observe ancient galaxies when they're so challenging to resolve? By looking at a whole bunch of them at once in a single spectral line and seeing how it changes...

3D print - galaxy

Image Caption purple, blue, and pink iridescent 3D model of the Steven's quintet galaxy cluster A researcher used software to convert an image of stars into...

Scientists use rare 'Einstein Cross' to learn about young galaxy with surprisingly old stars

"The discovery of this exceptional object has allowed us to accurately study the nature of the stars at the center of an elliptical galaxy in a remote era of the universe, when the...

Astronomers Stunned by Ancient Galaxy With No Spin

A massive galaxy from less than 2 billion years after the Big Bang is baffling astronomers because it shows no sign of rotation. Astronomers using the James Webb Space Telescope ha...

Hubble reveals spiral galaxy 53 million light-years away in striking detail

In this new image by the NASA/ESA Hubble Space Telescope, a spiral galaxy glittering with star clusters is the center of attention. NGC 3137 is located 53 million light-years away...
