Spirals, ellipticals, irregulars, oh my!
Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA's Chandra X-ray Observatory and ot...
A trio of NASA space telescopes teamed up to capture a gorgeous new look at the glowing spiral galaxy NGC 4258 and its two anomalous extra arms.
"Astronomy is not just science or spirit; it's both at the same time."
The Vera C. Rubin Observatory has released a stunning image of the COSMOS field. This image contains over half a million galaxies and fifty thousand stars. Astronomers have studied...
A greedy galaxy that existed less than 1.3 billion years after the Big Bang is hoarding supermassive black holes.
In this July 6, 2026, image, NASA's James Webb Space Telescope's Mid-Infrared Instrument (MIRI) reveals the nearby galaxy Centaurus A, exposing the dusty structures and hidden acti...
The Milky Way has a secret history of galaxy mergers that we are only now starting to uncover.
Galaxies in the infancy of the Universe are the building blocks of more modern galaxies. They began as small "shreds" of material that coalesced over time to form larger ones. That...
Observations of remote cosmic explosions reveal that the outer spiral arms of the Milky Way might extend farther out than previously thought. The post Gamma-Ray Bursts Size Up the...
The earliest example of the Milky Way cannibalising a smaller galaxy for its growth involved a cosmic meal that left a scar at the heart of our galaxy.
Understanding the formation and evolution of the centers of galaxies is one of the most intriguing challenges in astrophysics. The new study aims to unveil the physical processes t...
Three supermassive black holes in a distant and therefore very old galaxy offer a glimpse into how black holes merged and grew in the early universe. Light from the galaxy J0148-42...
Learn how two galaxies slowly pulling toward each other inspired a name that captures their cosmic collision and the birth of new stars within them.
Using a state-of-the-art galaxy simulation, a team led by scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) gained new insights into the processes shaping galact...
Researchers have obtained the deepest images ever taken of IC 1101, allowing them to identify the galaxy's outer edge for the first time. The observations confirm it as the largest...
It is not one object. It is a very large number of them, arranged in a curve on a scale larger than anyone had expected.
Observing our celestial neighbor (and something much farther away).
Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more...
The Whirlpool galaxy (M51) is a classic grand spiral galaxy. It was the first object identified as a spiral, way back in 1845. At the time, it and other galaxies were considered sp...
Here are some tips to get the most out of your galaxy images. The post Astrophotography: Picturing Galaxies appeared first on Sky & Telescope.
WASHINGTON: The Milky Way, a large and spiral-shaped galaxy that is home to hundreds of billions of stars including our sun, has taken a long and complicated path to achieve its....
Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's larges...
