From within the inky black plumes of the Chamaeleon I dark cloud, the light from three reflection nebulae breaks through

The ominous Chamaeleon I dark cloud, the nearest star-forming region to Earth, is captured in this image taken with the 570-megapixel Department of Energy-fabricated Dark Energy Camera mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. Chamaeleon I is one portion of the larger Chamaeleon Complex and is home to three reflection nebulae that are brightly illuminated by nearby newly formed stars.

The origin of our Sun, and all the planets, comets and asteroids that orbit it, can be traced back to their birthplace inside a massive cloud of cold gas and dust, not unlike the billowing molecular cloud featured in this image. Found within these cool regions of highly condensed interstellar material are stellar nurseries where young stars are emerging from the swirling gaseous plumes. These regions are also home to nebulae that shine bright with the reflected light of newly formed stars.

This image was captured with the 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam) mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. It showcases the atramentous molecular cloud known as the Chamaeleon I dark cloud. Located about 500 light-years away, Chamaeleon I is the nearest active star-forming region to Earth. This dark cloud is estimated to be around two billion years old and is home to about 200–300 stars.

Chamaeleon I is just a small component of the larger Chamaeleon Complex, an enormous active stellar birthplace that occupies almost the entirety of the southern constellation Chamaeleon, even overlapping into Apus, Musca, Carina and Octans. The Chamaeleon Complex also includes the Chamaeleon II and Chamaeleon III dark clouds, which show little and no active star formation, respectively.

Near the center of this image, brightly glowing from within the thick cosmic dust, is one of Chamaeleon I’s notable features, the stunning reflection nebula Cederblad 111. Reflection nebulae are clouds of gas and dust that do not create their own light, but instead shine by reflecting the light from nearby stars. This happens in the surroundings of newly formed stars that are not hot enough to excite the hydrogen atoms of the cloud, as is the case for emission nebulae. Instead, their light bounces off of the particles within the cloud.

Cederblad 110, a second reflection nebula within Chamaeleon I, can be seen just above Cederblad 111 with its recognizable C-shape. Like Cederblad 111, Cederblad 110 lies close to an active low-mass star forming region where the light of young stars is scattered by the nebula’s dust particles. This reflection creates a bright pocket of light amongst the otherwise opaque clouds.

Below the pair of reflection nebulae is the orange-tinted Chamaeleon Infrared Nebula. Resembling the wings of an ethereal cosmic aviator, this nebula is the product of streams of fast-moving gas that are being ejected from a newly formed low-mass star at the core of the nebula. These streams have carved a tunnel through the interstellar cloud where the young star was born. The infrared and visible light emitted by the nascent star escapes along this tunnel and scatters off its walls, giving rise to the wispy reflection nebula.

Embedded throughout Chamaeleon I, astronomers have also found numerous Herbig-Haro objects — bright patches of nebulosity that form when ionized jets of gas ejected from newly born stars collide with slow-moving gas in the surrounding cloud. One of these objects can be spotted as a tiny, faint red patch lying in the dusty realm between Cederblad 111 and Cederblad 110

NASA's Webb Telescope Unmasks True Nature of the Cosmic Tornado

Craving an ice cream sundae with a cherry on top? This random alignment of Herbig-Haro 49/50 — a frothy-looking outflow from a nearby protostar — with a multi-hued spiral galaxy may do the trick. This new composite image combining observations from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) provides a high-resolution view to explore the exquisite details of this bubbling activity.

Herbig-Haro objects are outflows produced by jets launched from a nearby, forming star. The outflows, which can extend for light-years, plow into a denser region of material. This creates shock waves, heating the material to higher temperatures. The material then cools by emitting light at visible and infrared wavelengths.

When NASA's retired Spitzer Space Telescope observed it in 2006, scientists nicknamed Herbig-Haro 49/50 (HH 49/50) the “Cosmic Tornado” for its helical appearance, but they were uncertain about the nature of the fuzzy object at the tip of the “tornado.”  With its higher imaging resolution, Webb provides a different visual impression of HH 49/50 by revealing fine features of the shocked regions in the outflow, uncovering the fuzzy object to be a distant spiral galaxy, and displaying a sea of distant background galaxies.

HH 49/50 is located in the Chamaeleon I Cloud complex, one of the nearest active star formation regions in our Milky Way, which is creating numerous low-mass stars similar to our Sun. This cloud complex is likely similar to the environment that our Sun formed in. Past observations of this region show that the HH 49/50 outflow is moving away from us at speeds of 60-190 miles per second (100-300 kilometers per second) and is just one feature of a larger outflow.

Webb’s NIRCam and MIRI observations of HH 49/50 trace the location of glowing hydrogen molecules, carbon monoxide molecules, and energized grains of dust, represented in orange and red, as the protostellar jet slams into the region. Webb’s observations probe details on small spatial scales that will help astronomers to model the properties of the jet and understand how it is affecting the surrounding material.

The arc-shaped features in HH 49/50, similar to a water wake created by a speeding boat, point back to the source of this outflow. Based on past observations, scientists suspect that a protostar known as Cederblad 110 IRS4 is a plausible driver of the jet activity. Located roughly 1.5 light-years away from HH 49/50 (off the lower right corner of the Webb image), CED 110 IRS4 is a Class I protostar. Class I protostars are young objects (tens of thousands to a million years old) in the prime time of gaining mass. They usually have a discernable disk of material surrounding it that is still falling onto the protostar. Scientists recently used Webb’s NIRCam and MIRI observations to study this protostar and obtain an inventory of the icy composition of its environment.

These detailed Webb images of the arcs in HH 49/50 can more precisely pinpoint the direction to the jet source, but not every arc points back in the same direction. For example, there is an unusual outcrop feature (at the top right of the main outflow) which could be another chance superposition of a different outflow, related to the slow precession of the intermittent jet source. Alternatively, this feature could be a result of the main outflow breaking apart.

The galaxy that appears by happenstance at the tip of HH 49/50 is a much more distant, face-on spiral galaxy. It has a prominent central bulge represented in blue that shows the location of older stars. The bulge also shows hints of “side lobes” suggesting that this could be a barred-spiral galaxy. Reddish clumps within the spiral arms show the locations of warm dust and groups of forming stars. The galaxy even displays evacuated bubbles in these dusty regions, similar to nearby galaxies observed by Webb as part of the PHANGS program.

Webb has captured these two unassociated objects in a lucky alignment. Over thousands of years, the edge of HH 49/50 will move outwards and eventually appear to cover up the distant galaxy.

Want more? Take a closer look at the image, “fly through” it in a visualization, and compare Webb’s image to the Spitzer Space Telescope’s.


Herbig-Haro 49/50 is located about 625 light-years from Earth in the constellation Chamaeleon.

The James Webb Space Telescope is the world's premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.
