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.

Barnard’s Loop Rising

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.

a Cosmic Convergence

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.

A Cosmic Neighborhood United in Imagery

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.

The Orion Nebula’s Miscalculated Bubble

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.

A Second Bubble

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.

An Unexpected Filament

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.
