NASA’s Webb Reveals Dynamic Panorama of Star Formation
NASA’s James Webb Space Telescope recently observed IC 348, a star-forming region just 1,000 light-years away from Earth. Webb’s sharp vision revealed tiny brown dwarfs, some just twice Jupiter’s mass, and young stars ejecting powerful jets crashing into surrounding gas and dust.

This starry view of the nearby star-forming region IC 348 is one of the largest images released to date from NASA’s James Webb Space Telescope. Using Webb, astronomers searched IC 348 for brown dwarfs, which are less massive than the smallest stars. The researchers discovered brown dwarfs just twice the mass of Jupiter, bringing the study of these curious objects into a new mass range and revealing new insights about the star formation process.
The star-forming region IC 348 is located just 1,000 light-years away in the constellation Perseus. In regions like IC 348, cold clouds of molecular hydrogen gas collapse to form new stars, creating glowing, sculpted scenes like this one. The star-formation process can create widely varied objects, from massive stars that expire after only a few million years in core-collapse supernova explosions to the smallest and most common stars, which are long lived and produce powerful stellar storms.

The smallest stars weigh in at around 8 percent of the Sun’s mass. Below this mass lies a strange class of objects called brown dwarfs. Brown dwarfs form in the same way stars do, through the collapse of molecular clouds. However, unlike stars, the cores of brown dwarfs never become hot enough to fuse ordinary hydrogen into helium (though many briefly fuse deuterium, or heavy hydrogen, early in their lives).
What’s still not clear, and what researchers hoped to learn by using Webb’s sensitive instruments to study IC 348, is how small the smallest objects created by the star-formation process are. In other words, how small is the smallest brown dwarf?
The team used Webb’s NIRCam (Near-Infrared Camera) in 2024 to capture the warm glow of young brown dwarfs and newborn stars seen in this new image of IC 348. After selecting candidate brown dwarfs based on their colors and brightness, they followed up with Webb’s NIRSpec (Near-Infrared Spectrograph) in 2025 to conduct spectroscopic observations to study the masses of the brown dwarfs.
These deep Webb observations revealed something remarkable to the researchers: brown dwarfs with masses as low as just twice the mass of Jupiter or only 0.19 percent of the Sun’s mass — far smaller than theory predicts brown dwarfs should be. These are the least massive brown dwarfs known and their existence poses a challenge to models of how stars form.
In addition to the discovery of these unexpectedly lightweight brown dwarfs, the Webb observations contained even more surprises. One of the lightest newfound brown dwarfs showed signs of a disk, suggesting that small planets could be forming around an object that is itself only the mass of a planet.
While inspecting the spectra of IC 348’s brown dwarfs, the research team also found a feature they attributed to an unidentified hydrocarbon — molecules made only of hydrogen and carbon atoms. This specific feature has only been seen in the atmospheres of the lowest-mass brown dwarfs, suggesting that these extreme objects might exist in a spectral class of their own.
The stars and brown dwarfs of IC 348 aren’t the only attractions in this image. A brilliantly detailed collection of protostars occupies the upper right corner. Several of these protostars are accompanied by Herbig-Haro objects, which are luminous regions that form when jets from growing newborn stars crash into the gas and dust around the star.
The long, narrow feature that is oriented horizontally in this corner is the Herbig-Haro object HH 797. Upon close inspection, this source is revealed to be two protostars with nearly parallel outflows. Just to the right of HH 797 is the propeller-shaped source HH 211, which features both narrow jets and broader outflows.

The data used to create this image comes from the Webb General Observer Program 4866. In addition to studying the lowest-mass objects created through the star-formation process, this program also seeks to understand how the populations of planetary-mass objects like brown dwarfs vary between star-forming regions, as well as the origins of the hydrocarbon feature in the lowest-mass brown dwarfs.
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 CSA (Canadian Space Agency).

APOD: 2026 September 15 – A Daytime Eclipse: Moon Occults Venus

A Daytime Eclipse: Moon Occults Venus
There was something behind the clouds. Upon close inspection, it was the Moon, which was hard to see yesterday around noon above the small village of Cessy, France. But soon, it was not only the Moon. As expected, a bright dot suddenly appeared from behind the Moon — the planet Venus far in the distance. Captured in the single featured exposure, both appeared to show a crescent phase. The Moon’s crescent was quite slight — with only about 10 percent of its face illuminated by the Sun. In contrast, Venus’s crescent was more full — showing about 25 percent illumination. Venus appeared brighter because it is nearer the Sun and because its clouds are more reflective than the dark lunar surface. An occultation of Venus by the Moon is visible to only about 10 percent of the Earth, but in yesterday’s event even most of that was experiencing daytime.
