A planetary system described as abnormal, chaotic, and strange by researchers has come into clearer view with NASA’s James Webb Space Telescope. Using Webb’s NIRCam (Near-Infrared Camera), researchers have successfully imaged one of two known planets surrounding the star 14 Herculis, located 60 light-years away from Earth in our own Milky Way galaxy.
The exoplanet, 14 Herculis c, is one of the coldest imaged to date. While there are nearly 6,000 exoplanets that have been discovered, only a small number of those have been directly imaged, most of those being very hot (think hundreds or even thousands of degrees Fahrenheit). The new data suggests 14 Herculis c, which weighs about 7 times the planet Jupiter, is as cool as 26 degrees Fahrenheit (minus 3 degrees Celsius).

Balmer (JHU), D. Bardalez Gagliuffi (Amherst College)
The team’s results covering 14 Herculis c have been accepted for publication in The Astrophysical Journal Letters and were presented in a press conference Tuesday at the 246th meeting of the American Astronomical Society in Anchorage, Alaska.
“The colder an exoplanet, the harder it is to image, so this is a totally new regime of study that Webb has unlocked with its extreme sensitivity in the infrared,” said William Balmer, co-first author of the new paper and graduate student at Johns Hopkins University. “We are now able to add to the catalog of not just hot, young exoplanets imaged, but older exoplanets that are far colder than we’ve directly seen before Webb.”
Webb’s image of 14 Herculis c also provides insights into a planetary system unlike most others studied in detail with Webb and other ground- and space-based `observatories. The central star, 14 Herculis, is almost Sun-like – it is similar in age and temperature to our own Sun, but a little less massive and cooler.
There are two planets in this system – 14 Herculis b is closer to the star, and covered by the coronagraphic mask in the Webb image. These planets don’t orbit the host star on the same plane like our solar system. Instead, they cross each other like an ‘X’, with the star being at the center. That is, the orbital planes of the two planets are inclined relative to one another at an angle of about 40 degrees. The planets tug and pull at one another as they orbit the star.
This is the first time an image has ever been snapped of an exoplanet in such a mis-aligned system.
Scientists are working on several theories for just how the planets in this system got so “off track.” One of the leading concepts is that the planets scattered after a third planet was violently ejected from the system early in its formation.
“The early evolution of our own solar system was dominated by the movement and pull of our own gas giants,” added Balmer. “They threw around asteroids and rearranged other planets. Here, we are seeing the aftermath of a more violent planetary crime scene. It reminds us that something similar could have happened to our own solar system, and that the outcomes for small planets like Earth are often dictated by much larger forces.”
Understanding the Planet’s Characteristics With WebbWebb’s new data is giving researchers further insights into not just the temperature of 14 Herculis c, but other details about the planet’s orbit and atmosphere.
Findings indicate the planet orbits around 1.4 billion miles from the host star in a highly elliptical, or football-shaped orbit, closer in than previous estimates. This is around 15 times farther from the Sun than Earth. On average, this would put 14 Herculis c between Saturn and Uranus in our solar system.
The planet’s brightness at 4.4 microns measured using Webb’s coronagraph, combined with the known mass of the planet and age of the system, hints at some complex atmospheric dynamics at play.
“If a planet of a certain mass formed 4 billion years ago, then cooled over time because it doesn’t have a source of energy keeping it warm, we can predict how hot it should be today,” said Daniella C. Bardalez Gagliuffi of Amherst College, co-first author on the paper with Balmer. “Added information, like the perceived brightness in direct imaging, would in theory support this estimate of the planet’s temperature.”
However, what researchers expect isn’t always reflected in the results. With 14 Herculis c, the brightness at this wavelength is fainter than expected for an object of this mass and age. The research team can explain this discrepancy, though. It’s called carbon disequilibrium chemistry, something often seen in brown dwarfs.
“This exoplanet is so cold, the best comparisons we have that are well-studied are the coldest brown dwarfs,” Bardalez Gagliuffi explained. “In those objects, like with 14 Herculis c, we see carbon dioxide and carbon monoxide existing at temperatures where we should see methane. This is explained by churning in the atmosphere. Molecules made at warmer temperatures in the lower atmosphere are brought to the cold, upper atmosphere very quickly.”
Researchers hope Webb’s image of 14 Herculis c is just the beginning of a new phase of investigation into this strange system.
While the small dot of light obtained by Webb contains a plethora of information, future spectroscopic studies of 14 Herculis could better constrain the atmospheric properties of this interesting planet and help researchers understand the dynamics and formation pathways of the system.
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).

I Am Artemis: Ernesto Garcia
Listen to this audio excerpt from Ernesto Garcia, Rayotech Scientific engineering manager:
0:00 / 0:00
Your browser does not support the audio element.My name is Ernesto Garcia, and I am an engineering manager at Rayotech Scientific in San Diego, in charge of fabricating the windowpanes for the Orion spacecraft.
Fabricating Orion’s windowpanes entails a very strict manufacturing process. It involves first starting from a giant sheet of glass that we cut down to near net shape. Once we get down to that near net shape, we perform a grinding operation. We grind the window edges and grind the faces.
The windows are visible on the Orion spacecraft crew module for Artemis I, shown here on May 2, 2019, undergoing direct field acoustic testing at NASA’s Kennedy Space Center in Florida.NASA/Rad Sinyak
Once we do all that grinding, we perform a specialized process where we actually strengthen the edges of the window. Since most of the window’s strength comes from the edges, we want to make sure that those are perfect and pristine, and so we minimize any subsurface damage that is around that. Then we send it off to get polished and coated.
After that, we perform pressure testing in our lab, which is really the most important thing that is required for this window to prove that it can survive in space. We apply the required stresses to make sure that the windows can survive on the Orion spacecraft.
The opportunity to be part of this program has been something that I’m really proud of.
When I was a child, I always wanted to work for NASA — and now, I work directly with NASA engineers, work with the windows first-hand, and work to develop processes.Ernesto Garcia
Engineering Manager, Rayotech Scientific
Coming up with ideas of how to manufacture [the windows] and then coming up with the pressure testing equipment to verify that they are going to survive in space was extremely fulfilling.
Being able to participate in Artemis I and seeing those windows on that [Orion spacecraft] — seeing it go into space — was probably one of the most rewarding things I’ve ever experienced besides having my kids. My children are immensely proud of what I’m doing. Seeing my kids’ reactions when I’m letting them know that I’m working directly with people that are putting things in space, with people that are making changes in the world — it’s something that inspires them.
NASA astronauts and Artemis II crew members Reid Wiseman and Victor Glover look through a window of Orion spacecraft mockup during Post Insertion and Deorbit Preparation training at the Space Vehicle Mockup Facility in Houston, Texas. The crew practiced getting the Orion spacecraft configured once in orbit, how to make it habitable, and suited up in their entry pressure suits to prepare for their return from the Moon.Mark Sowa – NASA – JSC
I imagine it will be a very special experience for the Artemis II astronauts to look out of these windows on their mission around the Moon. For them to be able to just look out and see what’s around them…to explore what else is out there from their eyes, not a camera’s point of view. It’s going to be pretty extraordinary that they’ll be able to see from their eyes — through our windows — something that not everybody else gets to see.
