a gas giant 12 times larger than Jupiter

NASA continues to amaze us with the prodigious capabilities of the James Webb Space Telescope. Not only for photographing galaxies never seen before, but also for taking the opportunity to take spectacular photos of Jupiter. Their latest achievement It was the first image of an exoplanet achieved with this telescope. One that is gigantic.

HIP65426b. It is not a very flattering name, but that is the name of this exoplanet that is the first to be captured by the new NASA, ESA and CSA space telescope.

gigantic and very young. This exoplanet is between six and 12 times larger than Jupiter and is relatively young: its age is about 15 to 20 million years, when the Earth formed about 4.5 billion years ago.

a complicated portrait. The planet was discovered in 2017 using the SPHERE instrument – ​​installed at an observatory in Chila – which allows images to be taken in infrared light, but Webb can go further in those wavelengths, and has now revealed new details that ground-based telescopes could not. captured by the infrared glow of the Earth’s atmosphere.

a little treasure. This is how Aarynn Carter describes the discovery. This researcher led the analysis of the images and found a common problem in the images of exoplanets: the stars are so bright that they tend to hide them, but she and her team managed to process the image, eliminate the brightness of the star HIP 65426 that is your hostess and discover the planet.

A planet far away from its star. It also helped that this planet is very far from its host star: no less than 100 times farther than the Earth is from the Sun. That allowed Webb to more easily “separate” the planet from the star in the image. By the way: HIP 65426 b is not habitable — it was expected — and it is a gas giant with no rocky surface.

This is how the James Webb Space Telescope is going to change the way we see the universe

This is just the beginning. As those responsible for this milestone pointed out, this is just the beginning and it is expected that the James Webb will take many more photos not only of discovered exoplanets, but also of undiscovered exoplanets.
