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 other telescopes displays a collection of galactic images that showcase this variety.
Astronomers put galaxies into three main categories: spirals like our own Milky Way with arms emanating from their cores, ellipticals that are older and likely the results of mergers, and irregulars that can encompass a wide range of galactic phenomena.
This gallery displays a collection of 16 galactic images from Chandra and other telescopes. Astronomers put galaxies into three main categories: spirals like our own Milky Way, ellipticals that are older and likely the results of mergers, and irregulars that can encompass a wide range of galactic phenomena.

Just as gems reveal the history of Earth through how they were forged over billions of years, these galactic gems are a way to study Earth’s place in our home galaxy of the Milky Way. By looking outward to other galaxies, we learn more about our own – including clues to its past and future.
There are 16 new images in this galactic gallery. Each one contains X-ray data from Chandra that has been collected across Chandra’s decades in space. This high-energy data has been combined with data from telescopes such as NASA’s James Webb and Hubble Space Telescopes, IXPE (Imaging X-ray Polarimetry Explorer), Neil Gehrels Swift Observatory, NuSTAR (Nuclear Spectroscopic Telescope Array), and others both on the ground and in space.

Major M104 Famous for its broad central bulge and dark outer dust ring, this galaxy sits at a nearly edge-on tilt to Earth. Chandra X-rays (cyan and orange) isolate compact point sources and hot gas in the galaxy’s sprawling halo, merged with Hubble optical light (warm white) and Webb infrared vision (purple-red dust lane). Studying M104 may help bridge the gap between spirals and ellipticals, helping astronomers better understand how a galaxy’s giant outer cloud of stars grows and ages alongside its inner disk. X-ray: NASA/CXC/SAO; Optical:NASA/Hubble Heritage Team/AURA/STScI; Infrared: NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/L. Frattare Arp 143 This ring galaxy system formed when a smaller companion galaxy punched straight through its center like a bullseye, creating a powerful cosmic shockwave. Chandra X-rays (purple) uncover bright X-ray binary systems scattered along the collision shock wave, laid over Hubble’s optical image (blue and white) of expanding stellar rings. Such head-on collisions can trigger vast ripple effects, sparking huge waves of star birth across entire galaxies. X-ray: NASA/CXC/SAO; Optical: NASA/ESA/STScI/J. Dalcanton; Image Processing: NASA/CXC/SAO/L. Frattare NGC 4725 A “one-armed” barred spiral galaxy surrounded by a prominent star-forming ring. Chandra’s X-ray data (magenta) pinpoints several bright X-ray sources, likely caused by growing black holes, embedded within the sweeping optical disk (soft blue and white) captured with the Mt. Lemmon Observatory. Galaxies with unusual single arms can offer a window into how the gravity from a passing galaxy can trigger bursts of star formation. X-ray: NASA/CXC/SAO; Optical: NASA/ESA/STScI/NAOJ/R. Gendler; Image Processing: NASA/CXC/SAO/L. Frattare NGC 1385 A barred spiral galaxy packed with regions where stars are actively forming. Chandra X-ray data (magenta) highlights stellar nurseries and X-ray binaries scattered along dusty spiral structures brought to life by Hubble optical (white and grey) and Webb infrared (orange and red) observations. Comparing multiwavelength data of barred spirals containing active star formation helps scientists map how local starbursts build up galactic mass over time. X-ray: NASA/CXC/SAO; Optical: NASA/ESA/STScI; Infrared: NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/L. Frattare NGC 660 A rare “polar ring” galaxy where a tilted outer ring of stars and dust rotates over the galaxy’s poles, an unusual structure likely caused by a collision with another galaxy about a billion years ago. Chandra’s X-rays (purple) reveal a possible growing supermassive black hole in the center of the galaxy, plus X-ray binaries nestled within the stars and dust captured by the Gemini Observatory in optical light (gold, blue and white). Studying polar rings teaches us about the diverse effects of stellar collisions on the shapes of galaxies. X-ray: NASA/CXC/SAO; Optical:NSF/International Gemini Observatory/AURA; Image Processing: NASA/CXC/SAO/L. Frattare M82 An irregular galaxy undergoing intense star formation because of a gravitational interaction with a neighboring galaxy hundreds of millions of years ago. Chandra X-rays (blue), supplemented by NuSTAR data, show towering superwinds of million-degree gas blowing thousands of light-years out of the galactic disk, with Hubble optical light (yellow, orange and white) showing the galaxy shape, and Webb and Spitzer detailing infrared dust emission (red). M82 was nicknamed the Cigar Galaxy mostly because of its edge-on angle to Earth, which makes its central disk look like an elongated, cigar-shaped oval with small optical telescopes. The galaxy illustrates how violent galactic “exhaust systems” can regulate a galaxy’s growth by venting gas outwards. X-ray: NASA/CXC/SAO; Optical: NASA/ESA/STScI; Infrared: NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/L. Frattare, J. Major, and K. Arcand NGC 3256 A pair of colliding, gas-rich spiral galaxies merging into a single massive system. Chandra’s X-ray data (pink) isolates point sources and shock-heated gas, Hubble’s optical light (blue and white) captures tidal tails of stars, and Webb’s infrared vision (red and orange) cuts through the dust to show hidden star formation. Galaxy collisions like this offer a preview of our far future, showing what might happen if our own Milky Way collides and merges with the nearby Andromeda Galaxy. X-ray: NASA/CXC/SAO; Optical: NASA/ESA/STScI; Infrared: NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/L. Frattare NGC 3938 A face-on spiral galaxy whose orientation gives us an unobstructed view of its disk. X-ray emissions from Chandra (magenta) detail energetic X-ray binaries and supernova remnants scattered across dust lanes in an optical image (white, blue and gold) from Adam Block with Mt. Lemmon Observatory. Face-on orientations are important for galactic studies because they provide the most unobstructed views of a galaxy’s stars and gas. X-ray: NASA/CXC/SAO; Optical: Adam Block/Mount Lemmon SkyCenter/University of Arizona; Image Processing: NASA/CXC/SAO/L. Frattare NGC 4631 A spiral galaxy viewed from its side, featuring a giant halo of hot gas blowing out of its stellar disk. X-rays from Chandra and ESA’s XMM-Newton (purple and royal blue) trace hot gas driven out by supernovas and black holes and neutron stars pulling gas from their companions, while optical light (light blue, gold and white) from ground-based observer R. Jay GaBany showcases dense dust lanes. Edge-on views of galaxies allow astronomers to study how flat their stellar disks are and provide the clearest views of material located above or below the disk. X-ray: NASA/CXC/SAO; Optical: ©2011-2015 by R Jay GaBany, Cosmotography.com; Image Processing: NASA/CXC/SAO/L. FrattareX-rays are critical for the study of galaxies, revealing unique and important information about these cosmic building blocks. For example, Chandra exposes gas that has been superheated to millions of degrees by winds from massive stars, the outflows from supermassive black holes, and the debris from exploded stars. These are key sources of elements in our bodies, in the air we breathe, and the planet we live on. Chandra also sees some of the hottest and most energetic galactic phenomena in the universe, forming a more complete picture of how galaxies live, interact, and evolve when combined with data from other types of light and telescopes.
Spiral and star-forming engines
Face-on spiral galaxies like Messier 33 and NGC 3938 offer unobstructed views of places where energetic pairs of stars and cosmic explosions live along spiral arms. Barred spirals like NGC 1672 and NGC 1385 show how central bar-shaped collections of stars, gas, and dust funnel fuel inward to ignite bursts of star formation. NGC 4725 reveals how star formation can be triggered by a previous collision with another galaxy. Meanwhile, edge-on views of NGC 4631 (the Whale Galaxy) and the starburst Messier 82 (the Cigar Galaxy) showcase giant halos and superwinds of million-degree gas driven thousands of light-years into space by intense explosions of stars, enriching surrounding intergalactic space with vital elements.
Active galactic nuclei, black hole outflows
Powerful, growing black holes in the cores of their host galaxies, known as active galactic nuclei, send energy outward in outbursts and jets that impact entire galaxies. In Centaurus A, Chandra and IXPE data expose a high-energy particle jet blasting tens of thousands of light-years into space from its central engine. In Messier 106, jets from the supermassive black hole heat surrounding gas to create spiral arms that are different from those typically found in spiral galaxies. Meanwhile, the iconic Sombrero Galaxy (Messier 104) highlights a supermassive black hole embedded in a colossal stellar bulge, where Chandra’s X-rays map a diffuse halo of million-degree gas and hot stellar remnants surrounding its sweeping dust lanes.
Collisions, mergers, cosmic disruptions
The gallery also showcases galaxies undergoing extreme gravitational transformations. A direct impact in Arp 143 acts like a cosmic bullseye, creating an expanding ring galaxy and triggering waves of star birth. Violent mergers, such as NGC 3256 and the dust-shrouded starburst II Zw 096, reveal the kind of chaotic galaxy collisions that dominated the early universe and offer a preview of the Milky Way’s distant future merger with nearby galaxy Andromeda. NGC 1569 acts as a local laboratory for studying early universe starbursts, NGC 660 showcases a rare “polar ring” galaxy where a ring of stars orbits over its poles, and Messier 90 shows a spiral galaxy plowing through the Virgo Cluster, having its star-forming gas violently stripped away.
