galaxy

This JWST image shows the Big Wheel galaxy (in the center) and its cosmic environment. The galaxy is a gigantic rotating disk lying 11.7 billion light-years away. Its spiral disk stretches across 100,000 light-years, making it larger than any other galaxy disk confirmed at this epoch of the universe. The blue blob and some of the other larger objects in the image are galaxies in the nearby universe. The smaller objects tend to be distant galaxies; however, the larger galaxy to the lower left of Big Wheel is part of the same remote galactic structure as Big Wheel. Credit: NASA/ESA

Astronomers Find Giant Dinosaur of a Galaxy

This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc galaxy existing only 700 million years after the Big Bang. This makes it the most distant and earliest known Milky Way-like galaxy found to date.

A galaxy suddenly became much brighter in late 2019. This reveals a giant black hole at its center that's woken up and started feeding on surrounding gas, making the whole galaxy light up. This is the first time scientists have observed this awakening happen.

A 3D rendered image of the spiral galaxy NGC 4151, with a bright central region representing the active galactic nucleus. The image zooms in to show a glowing accretion disk surrounding a supermassive black hole, with twin jets of particles emanating from the disk's center. Colorful spectral lines are overlaid on the image, highlighting the iron fingerprints detected by XRISM's Resolve instrument.

The second- and fourth-most distant galaxies ever seen (UNCOVER z-13 and UNCOVER z-12) have been confirmed using the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). The galaxies are located in Pandora’s Cluster (Abell 2744), show here as near-infrared wavelengths of light that have been translated to visible-light colors. The scale of the main cluster image is labelled in arcseconds, which is a measure of angular distance in the sky. The circles on the black-and-white images, showing the galaxies in the NIRCam-F277W filter band onboard JWST, indicate an aperture size of 0.32 arcsec.

The Hubble Space Telescope has captured an image of an object in the ultraviolet part of the spectrum, which appears similar in size to our Milky Way. Researchers have been puzzled by this object for some time, but recently found similarities between it and a nearby galaxy known as IC 5249, which lacks a bulge and is observed edge-on. The images in ultraviolet and visible light of both objects are strikingly similar and suggest that the object could be a galaxy without a bulge viewed edge-on. Credit for the images goes to HST.
