      6 Min Read NASA’s Chandra Releases New 3D Models of Cosmic Objects
      New three-dimensional (3D) models of objects in space have been released by NASA’s Chandra X-ray Observatory. These 3D models allow people to explore — and print — examples of stars in the early and end stages of their lives. They also provide scientists with new avenues to investigate scientific questions and find insights about the objects they represent.
      These 3D models are based on state-of-the-art theoretical models, computational algorithms, and observations from space-based telescopes like Chandra that give us accurate pictures of these cosmic objects and how they evolve over time.
      However, looking at images and animations is not the only way to experience this data. The four new 3D printable models of Cassiopeia A (Cas A), G292.0+1.8 (G292), Cygnus Loop supernova remnants, and the star known as BP Tau let us experience the celestial objects in the form of physical structures that will allow anyone to hold replicas of these stars and their surroundings and examine them from all angles.
      Cassiopeia A (Cas A)
      Using NASA’s James Webb Space Telescope, astronomers uncovered a mysterious feature within the remnant, nicknamed the “Green Monster,” alongside a puzzling network of ejecta filaments forming a web of oxygen-rich material. When combined with X-rays from Chandra, the data helped astronomers shed light on the origin of the Green Monster and revealed new insights into the explosion that created Cas A about 340 years ago, from Earth’s perspective.

      X-ray: NASA/CXC/SAO; Optical: PanSTARRS; Image Processing: NASA/CXC/SAO/N. Wolk This 3D model shows a star less than 10 million years old that is surrounded by a disk of material. This class of objects is known as T Tauri stars, named after a young star in the Taurus star-forming region. The model describes the effects of multiple flares, or outbursts that are detected in X-rays by Chandra from one T Tauri star known as BP Tau. These flares interact with the disk of material and lead to the formation of an extended outer atmosphere composed by hot loops, connecting the disk to the developing star.

      X-ray: NASA/SAO/CXC; Optical: John Stone (Astrobin); Image Processing: NASA/SAO/CXC/L. Frattre, N. Wolk The Cygnus Loop (also known as the Veil Nebula) is a supernova remnant, the remains of the explosive death of a massive star. This 3D model is the result of a simulation describing the interaction of a blast wave from the explosion with an isolated cloud of the interstellar medium (that is, dust and gas in between the stars). Chandra sees the blast wave and other material that has been heated to millions of degrees. The Cygnus Loop is a highly extended, but faint, structure on the sky: At three degrees across, it has the diameter of six full moons.

      3D Model of Cygnus LoopINAF-Osservatorio Astronomico di Palermo/Salvatore Orlando G292.0+1.8
      X-ray: NASA/CXC/SAO; Optical:NSF/NASA/DSS; Image Processing This is a rare type of supernova remnant observed to contain large amounts of oxygen. The X-ray image of G292.0+1.8 from Chandra shows a rapidly expanding, intricately structured field left behind by the shattered star. By creating a 3D model of the system, astronomers have been able to examine the asymmetrical shape of the remnant that can be explained by a “reverse” shock wave moving back toward the original explosion.

      Visual Description
      This release features visualizations of three supernova remnants and one star. Each is rendered as a composite image, and as a digital 3-dimensional model, presented in separate short video clips. The composite images are two dimensional and static, but the digital models rotate, showcasing their three-dimensionality.
      The first featured supernova is Cassiopeia A. In the X-ray, optical, and infrared composite image, the debris from an exploded star resembles a round purple gas cloud, marbled with streaks of golden light. In the rotating, 3D model, the purple gas cloud is depicted as a flat disk, like a record or CD. Bursting out the front and back of the disk is an orange and white shape similar to a ball of coral, or a head of cauliflower lined with stubby tendrils. Most of the ball, and the majority of the tendrils, appear on one side of the disk. On the opposite side, the shape resembles dollops of thick whipped cream.
      Next in the release is a star known as BP Tau. BP Tau is a developing star, less than 10 million years old, and prone to outbursts or flares. These flares interact with a disk of material that surrounds the young star, forming hot loops of extended atmosphere. In the composite image, BP Tau resembles a distant, glowing white dot surrounded by a band of pink light. The rotating, 3D model is far more dynamic and intriguing! Here, the disk of material resembles a large blue puck with round, ringed, concave surfaces. At the heart of the puck is a small, glowing red orb: the developing star. Shooting out of the orb are long, thin, green strands: the flares. Also emerging from the orb are orange and pink petal-shaped blobs: the loops of extended atmosphere. Together, the orb, strands, and petals resemble an exotic flowering orchid.
      The third celestial object in this release is the supernova remnant called Cygnus Loop. In the composite image, the remnant resembles a wispy cloud in oranges, blues, purples, and whites, shaped like a backwards letter C. The 3D model examines this cloud of interstellar material interacting with the superheated, supernova blast wave. In the 3D model, the Cygnus Loop resembles a bowl with a thick base, and a wedge cut from the side like a slice of pie. The sides of the bowl are rendered in swirled blues and greens. However, inside the thick base, revealed by the wedge-shaped cut, are streaks of red and orange. Surrounding the shape are roughly parallel thin red strands, which extend beyond the top and bottom of the digital model.
      The final supernova featured in this release is G292.0+1.8. The composite image depicts the remnant as a bright and intricate ball of red, blue, and white X-ray gas and debris set against a backdrop of gleaming stars. In the 3D model, the remnant is rendered in translucent icy blue and shades of orange. Here, the rotating shape is revealed to be somewhat like a bulbous arrowhead, or perhaps an iceberg on its side.

      Exploring the Universe Through Sight, Touch, and Sound
      For the first time in history, we can explore the universe through a rich blend of senses—seeing, touching, and hearing astronomical data—in ways that deepen our understanding of space. While three-dimensional (3D) models are essential tools for scientific discovery and analysis, their potential extends far beyond the lab.
      Space can often feel distant and abstract, like watching a cosmic show unfold on a screen light-years away. But thanks to remarkable advances in technology, software, and science, we can now transform telescope data into detailed 3D models of objects millions or even billions of miles away. These models aren’t based on imagination—they are built from real data, using measurements of motion, light, and structure to recreate celestial phenomena in three dimensions.
      What’s more, we can bring these digital models into the physical world through 3D printing. Using innovations in additive manufacturing, data becomes something you can hold in your hands. This is particularly powerful for children, individuals who are blind or have low vision, and anyone with a passion for lifelong learning. Now, anyone can quite literally grasp a piece of the universe.
      These models also provide a compelling way to explore concepts like scale. While a 3D print might be just four inches wide, the object it represents could be tens of millions of billions of times larger—some are so vast that a million Earths could fit inside them. Holding a scaled version of something so massive creates a bridge between human experience and cosmic reality.
      In addition to visualizing and physically interacting with the data, we can also listen to it. Through a process called sonification, telescope data is translated into sound, making information accessible and engaging in a whole new way. Just like translating a language, sonification conveys the essence of astronomical data through audio, allowing people to “hear” the universe.
      To bring these powerful experiences to communities across the country, NASA’s Universe of Learning, in collaboration with the Library of Congress, NASA’s Chandra X-ray Observatory, and the Space Telescope Science Institute, has created Mini Stars 3D Kits that explore key stages of stellar evolution. These kits have been distributed to Library of Congress state hubs across the United States to engage local learners through hands-on and multisensory discovery.
      Each Mini Stars Kit includes:
      Three 3D-printed models of objects within our own Milky Way galaxy: Pillars of Creation (M16/Eagle Nebula) – a stellar nursery where new stars are born Eta Carinae – a massive, unstable star system approaching the end of its life Crab Nebula – the aftermath of a supernova, featuring a dense neutron star at its core Audio files with data sonifications for each object—mathematical translations of telescope data into sound Descriptive text to guide users through each model’s scientific significance and sensory interpretation These kits empower people of all ages and abilities to explore the cosmos through touch and sound—turning scientific data into a deeply human experience.

      Image: This Copernicus Sentinel-2 image shows part of one of the world’s natural wonders – the Great Barrier Reef in the Coral Sea off the east coast of Queensland, Australia.
      Zoom in to explore this image at its full resolution or click on the circles to learn more. 
      The Great Barrier Reef extends for nearly 2300 km and covers an area of more than 344 000 sq km, approximately the size of Italy. It is the largest living organism on Earth and the only living thing the naked eye can see from space.
      Despite its name, the Great Barrier Reef is not a single reef, but an interlinked system of about 3000 reefs and 900 coral islands, divided by narrow passages. An area of biodiversity equal in importance to tropical rainforests, the reef hosts more than 1500 species of tropical fish, 400 types of coral, hundreds of species of bird and seaweed and thousands of marine animals, including sharks, barracuda and turtles.
      In recognition of its significance the reef was made a UNESCO World Heritage Site in 1981.
      The section of reef seen here is the southern part off the coast of the Shire of Livingstone in Central Queensland. Part of the mainland and the islands surrounding the coast are visible in the bottom left corner. The tan-coloured sea along the coasts is due to sediment in the water.
      A chain of small coral islands can be seen scattered across the centre of the image. The blue hues of the coral contrast with the dark waters of the Coral Sea.
      Part of the reef is covered by clouds dominating the upper part of the image. The clouds form a surprisingly straight line, also visible as a distinct shadow cast over the islands below.
      Coral reefs worldwide suffer regular damage due to climate change, pollution, ocean acidification and fishing. Furthermore, they are increasingly under threat from coral bleaching, which occurs when the algae that makes up the coral die, causing it to turn white. This phenomenon is associated with increased water temperatures, low salinity and high sunlight levels.
      While these coral reefs are ecologically important, they are difficult to map from survey vessels or aircraft because of their remote and shallow location. From their vantage point in space, Earth-observing satellites such as Copernicus Sentinel-2, offer the means to monitor the health of reefs across the globe.

      In northwest Australia, the Great Sandy Desert holds great geological interest as a zone of active sand dune movement. While a variety of dune forms appear across the region, this astronaut photograph features numerous linear dunes (about 25 meters high) separated in a roughly regular fashion (0.5 to 1.5 kilometers apart).NASA On March 25, 2013, an astronaut aboard the International Space Station took this photo of the Great Sandy Desert in northwest Australia, showcasing linear dunes separated in a roughly regular fashion. When you fly over such dune fields—either in an airplane or the space station—the fire scars stand out. Where thin vegetation has been burned, the dunes appear red from the underlying sand; dunes appear darker where the vegetation remains.
      Strings of narrow lakes that represent ancient rivers are also present in the region. The white feature down the center of the image is Lake Auld. The color is the result of a cemented combination of fine, clay-like sediment and salts from the evaporation of flood waters that occasionally fill the lake. Linear dunes can be seen entering Lake Auld on the east side. During flooding events, the sand of the dune noses is dispersed, becoming incorporated into the muds and salts of the lake floor sediments. During the long, intervening dry periods, sand can blow across the lake floor to build thinner, smaller dunes, visible as linear accumulations on the west side of the lake.
