Stunning new imagery of the distant celestial object NGC 2392, better known as the “Lion Nebula,” has been obtained by NASA’s James Webb Space Telescope.
The cosmic vista captured by Webb reveals a colorful view of the ancient nebula, whose characteristic appearance resembles one of nature’s most respected apex predators, complete with a bushy-looking “mane” composed of hazy stellar gases and objects similar to comets.
The new high-resolution imagery offers one of the clearest and most detailed views of the Lion Nebula ever seen. Previous images captured by Webb’s predecessor, the Hubble Space Telescope, were obtained in 2000, featuring the same celestial feature in visible light.
With the added spectral ranges Webb’s Near Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) can capture, the Lion Nebula now appears in colorful pinks and indigo hues, surrounded by distant galaxies blazing in brilliant orange from across vast cosmic distances, whose light has traveled billions of years to reach our Solar System.
A particularly striking feature about the new imagery is the way cosmic dust and regions of ionized gas are showcased in the new Webb imagery.
“It’s taken several thousand years for this collection of gas and dust to reach its current shape, and the nebula’s components continue to be altered,” read a portion of a statement released by the European Space Agency (ESA) that accompanied the new images.
One reason that helps account for the changing appearance of the Lion Nebula over time can be found at its center, where the remnants of a slowly dying white dwarf star (which effectively forms the nose in the lion’s face after which the nebula is named) continues to supercharge the surrounding cosmic structures made visible in the new Webb imagery.
The rest of the lion’s face is composed of an expanding bubble of ionized gas, the nature of which remains somewhat mysterious. Presently, astronomers are uncertain about what exact mechanisms give rise to the complex appearance of this gassy bubble and its internal structures, which are a recurring element in ancient nebulae such as this.
NGC 2392 isn’t the only celestial feature known as the “Lion Nebula.” An entirely separate diffuse nebula located in the Cepheus constellation, known as Sharpless 2-132, also shares this nickname due to its shape, which resembles a lion’s body seen from the side.
For now, the Lion Nebula is captured in the Webb imagery, which, despite its almost serene beauty, represents a highly active area of the cosmos, undergoing constant change as material is continually ripped away from the stellar central core.
Sometime in the next 10,000 years or so, this striking celestial feature will eventually be destroyed, once the white dwarf powering the nebula completely dies and the remnants of stellar material are completely dispersed into the surrounding space.
Until then, this remarkable cosmic feature will remain a target of study by astronomers, whose inquiries are helped significantly by the unprecedented clarity offered in the latest Webb images.
Additional information about the Lion Nebula (NGC 2392) can be found on NASA’s official page documenting the Webb MIRI imagery.

Two dormant volcanoes in the Andes are shown “connected” by the glowing ribbon of a distant cosmic feature stretching across the sky between them, in a rare cosmic alignment echoing ancient legends about these neighboring peaks—and all of it was captured in one of the most breathtaking astronomy images in recent memory.
The photo (seen below) was captured by astrophotographer Gonzalo Laserna Vargas and showcased by the American space agency this week. In it, we see Parinacota and Pomerape, a pair of ancient stratovolcanoes that form an unmistakable part of the landscape along the border between Bolivia and Chile.
In local folklore, these two prominences represent a prince and princess whose forbidden romance forever linked them in myth. Although no geological evidence exists for any physical links between them, astronomy recently helped fulfil that mythic connection in an unprecedented night sky display. The unique conditions that made this image possible, as well as the planning and preparation that went into it, were described by Vargas in a recent post on his Instagram account.
In the new imagery, recently featured as NASA’s Astronomy Picture of the Day, Barnard’s Loop—a vast arc of glowing hydrogen gas surrounding part of the constellation Orion—is showcased in a long-exposure photograph as it appears behind the two volcanoes.
The image was captured coinciding with the appearance of the nebula directly behind the volcanoes, and from an angle that causes the visible portion of the celestial object to appear as though it is rising from the mouths of the ancient volcanic peaks, uniting them through what resembles a colorful, luminous aerial display.
Despite the awe-inspiring appearance of the imagery, as part of the larger Orion Molecular Cloud, Barnard’s Loop remains at a distance of around 440 parsecs from these dormant volcanic peaks—in other words, close to 1,400 light-years away.
Capturing a cosmic convergence at this scale required careful planning by Vargas, who took a sequence of exposures from the same location in Bolivia in mid-April, at a time when the nebula appeared perfectly in between the two mountain summits.
One thing that helped with this is the fact that Barnard’s Loop is one of the largest emission nebulae visible from Earth. Although it is far too faint to be seen easily with the naked eye, the nebula’s vibrant pink and orange colors appear in long-exposure photography, revealing its eerie halo fueled by the presence of hydrogen gas.
Along with Barnard’s Loop, several of the night sky’s most recognizable objects also make an appearance in Vargas’s photo. Near the center of the image is the Orion Nebula, which happens to be one of the nearest stellar nurseries to Earth. Such areas of the cosmos are places where new star formation occurs within vast clouds of cosmic dust and gas.
To the nebula’s right, Betelgeuse is also visible, the reddish supergiant which was recently confirmed to have a stellar companion after more than a century of speculation about what might cause unusual variances in its brightness.
Higher in the image, another striking feature—the Rosette Nebula—can also be seen, revealed as a massive cloud of glowing gas around a small group of young stars.
Although each of these features is separated by hundreds or even thousands of light-years from Vargas’s imagery, they all appear in a singular frame, producing a dramatic cosmic backdrop for the ancient volcanic landscape they appear above.
Hence, for reasons that are easy to see, Vargas’s photo was named NASA’s Astronomy Picture of the Day for July 28, 2026, revealing another artful view of the cosmos that relies on far more than just advanced equipment—it also showcases the necessity for astronomical knowledge, careful preparation, and, of course, impeccable timing.
The result in this case is a moment captured in time, where mythology, an ancient volcanic landscape, and the cosmos all converge within a single frame.

A key component of the Orion Nebula had escaped detection by astronomers until now, according to a new study in Astronomy & Astrophysics.
An international team led by Juan Diego Soler at the University of Vienna used two of the world’s most advanced radio telescopes to map neutral atomic hydrogen gas across the nebula’s outer shell at unprecedented resolution. The new maps provide a clearer view of the celestial feature, and reveal a previously uncatalogued second bubble—a shell with much less mass than earlier estimates—and a four-light-year filament of gas extending from the structure.
Neutral hydrogen emits a faint radio signal at a wavelength of 21 centimeters, making it possible to trace otherwise invisible gas between the stars. Soler’s team solved this by combining data from the Karl G. Jansky Very Large Array in New Mexico and the FAST telescope in China. The VLA provided high resolution, while FAST picked up faint, widespread signals. Together, they produced the first detailed hydrogen map of the extended Orion Nebula, at the same scale as earlier ionized carbon maps.
Earlier calculations based on ionized carbon estimated that the front half of the shell was about 1,100 times the mass of our Sun. The hydrogen observations paint a different picture, suggesting the shell actually weighs in at closer to 100 solar masses. “Measuring mass is fundamental,” Soler said, “because it tells us about the efficiency of these newly formed stars shaping their environment with wind and radiation.”
A shell with only a tenth of the previously assumed mass significantly alters calculations of how efficiently newly formed stars shape their environment. The researchers note that molecular hydrogen, which is not detected in either the hydrogen or carbon data, may account for some of the missing mass.
The hydrogen maps also revealed an uneven distribution of gas, indicating a second, smaller cavity within the main shell. The team searched catalogs of known stars and young stellar objects in the region but found no candidate at the bubble’s center. The source responsible for creating the cavity may not be the type of object included in current catalogs.
Daniel Seifried at the University of Cologne, a co-author on the study, pointed to what that means for the models astronomers build to explain regions like this one. “These stunning observations serve as a reference for many modern astrophysical simulations investigating the evolution of gas and stars in the Milky Way. These are the kind of images that challenge the theoretical models and numerical simulations that we use to understand how massive stars affect their immediate surroundings.”
Previous models generally treated Orion’s shell as the product of a single expanding bubble. The discovery of a second cavity, with no obvious source at its center, instead suggests the nebula was shaped by multiple episodes of stellar feedback.
The new maps also uncovered a filament of hydrogen extending about four light-years from the shell’s western edge. Previous carbon-based observations saw only the base of this structure. The filament contains about 80 solar masses of hydrogen and does not appear to be associated with any known group of young stars. Its origin is unclear; it could be gas leaking through a weak spot in the shell or a leftover from the original cloud that existed before the bubble formed.
Claire Murray of the Space Telescope Science Institute, another co-author, framed the discovery within the broader push behind the observations. “This study is an exciting demonstration of the power of the latest-generation radio telescopes to uncover new pieces to the star formation puzzle.” Despite being one of the galaxy’s most extensively studied star-forming regions, the Orion Nebula continues to reveal discoveries.
This survey is the first scientific result from the NeAtHood project, which aims to map atomic hydrogen across nearby star-forming regions accessible to the VLA and FAST telescopes. Soler and his colleagues now plan to apply the same approach to additional targets. “Orion is only the beginning. Our newly developed methods show how future interferometers will reveal the hidden structure and dynamics of the interstellar medium—even in regions that astronomers already believed they understood well,” Soler explained.
If one of the sky’s best-studied star-forming regions still contains hidden structures, other nearby nebulae may prove equally surprising as the NeAtHood survey expands.
