When the first images from the James Webb Space Telescope were released in 2022, one in particular became instantly iconic: a striking orange and blue view of the Carina Nebula, affectionately known as the Cosmic Cliffs. Now, a visualization from NASA gives a new way to experience that iconic image in 3D.
NASA scientists worked together with others from the Space Telescope Science Institute (STScI), Caltech/IPAC, Center for Astrophysics | Harvard & Smithsonian, and NASA’s Jet Propulsion Laboratory to create this 3D visualization of the beautiful nebula. Using data from James Webb as well as the Hubble and now-retired Sptizer space telescopes plus the Chandra X-ray Observatory, you can see how the nebula appears in different wavelengths of light, from visible light to X-ray to infrared.
The video takes you from the heart of the nebula, zooming out to see the structures of dust and gas before heading to the famous Cosmic Cliffs. Then the visualization shows what it would look like to fly over the cliffs, exploring them in three dimensions.
The nebula gets its complex shape from the interplay of newborn stars and the dust and gas they are formed from. When stars are born, they give off gusts of stellar winds which push away material and sculpt it into delicate shapes. And when enough dust and gas is packed into one area, it can stick together due to the forces of gravity and become the core of a new star.
The region of the nebula known as the Cliffs is technically called Gum 31, where stars in the bright young cluster NGC 3324 have carved the cliff-like shapes in the clouds of dust.
“Bringing this amazing set of multiwavelength images to life showcases the variety of scientific features revealed by NASA’s space observatories,” said leader of the project, Frank Summer of STScI. “Plus, with the Cosmic Cliffs fly-through, one can experience the three-dimensional structure inherent in the 2D image, and foster a better mental model of the universe.”
After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.
Starship has 26 Starlink satellites to deliver
For decades, humanity has looked up at the Moon and wondered what it would be like to live on it. Think sprawling cities, factories, research centers, and permanent human settlements. Unfortunately, there is one fairly fundamental problem with that vision.
A new study published in Frontiers in Space Technologies argues that even the Moon's potentially enormous reserves of frozen water may be nowhere near enough to support city-sized populations sustainably. Researchers Martin Elvis and Jonathan McDowell estimate that the permanently shadowed regions near the lunar poles could contain roughly one billion tons of water. It sounds like an extraordinary amount until you put a million thirsty humans next to it.
