A Chilly Giant: The Coldest Planet Ever Photographed
14 HerculisSun Jun 15 2025
The James Webb Space Telescope has done it again. This time, it has captured a stunning image of a cold, massive planet orbiting a star. This planet, named 14 Herculis c, is a whopping seven times bigger than Jupiter. It is located about 60 light-years away from Earth. This makes it one of the farthest planets ever directly photographed. The planet is so cold that its temperature is a mere 26 degrees Fahrenheit (minus 3 degrees Celsius). This is surprisingly chilly for a planet. Most planets that have been directly imaged are scorching hot. So, this discovery is quite unusual.
The planet is part of a star system that is quite different from our own. In our solar system, all planets orbit the sun in the same plane. However, the two planets in the 14 Herculis system are tilted at an angle of about 40 degrees relative to each other. This misalignment suggests that something dramatic happened early in the system's formation. Scientists think a third planet might have been kicked out of the system. This could have caused the remaining planets to shift into their unusual orbits. It is a reminder that our own solar system could have had a similar chaotic past.
The James Webb Space Telescope was able to capture this image thanks to its advanced technology. The telescope's Near-Infrared Camera (NIRCam) can detect near-infrared light. This type of light is just beyond what the human eye can see. Cold objects shine brightly in infrared light. So, the telescope's ability to detect this light made it possible to photograph the cold planet. This discovery opens up a new area of study for scientists. They can now explore older, colder exoplanets that were previously too difficult to observe.
The James Webb Space Telescope is a remarkable piece of technology. It has a primary mirror that is 21 feet (6. 5 meters) in diameter. This mirror is made from beryllium and is covered in a thin layer of gold. The gold coating helps the mirror reflect infrared light more effectively. The telescope was designed to last for five to ten years. However, due to fuel-saving measures during its launch, it is now expected to operate for up to 20 years. This means that scientists will have plenty of time to make more exciting discoveries.
The discovery of 14 Herculis c is a significant achievement. It shows how much we still have to learn about the universe. Every new planet that is discovered challenges our understanding of how planetary systems form and evolve. This discovery is a reminder that there is still so much out there waiting to be explored. It is an exciting time for astronomy, and the James Webb Space Telescope is at the forefront of this exploration. It is helping us to see the universe in a whole new light.
