exoplanet

The James Webb Space Telescope has snapped its first direct images of an exoplanet. With its uniquely powerful instruments, Webb captures details that other observatories miss, which will help us understand these distant worlds better and potentially find the first signs of extraterrestrial life.Most exoplanets are detected and studied indirectly through their host star, such as how it wobbles from the gravitational influence as it orbits or how it blocks the light as it passes in front of the star. Directly imaging these…

In yet another historic moment, the James Webb Space Telescope has captured the first-ever direct image of an exoplanet. The planet in question, known as HIP 65426 b, is between six to 12 times the mass of Jupiter. It’s roughly 15 million to 20 million years old and was originally discovered in 2017. The capturing of this new image is so notable because this is the first time we have ever captured an image of a planet outside of our solar system. Yes, we have detected them, and James Webb has even detected carbon…

There it is, in four different bands of the infrared spectrum: the gas giant HIP 65426b, the first exoplanet directly imaged by the Webb Space Telescope.“Obtaining this image felt like digging for space treasure,” said Aarynn Carter, an astronomer at the University of California, Santa Cruz, who led the analysis of the images, in a NASA release. “At first all I could see was light from the star, but with careful image processing I was able to remove that light and uncover the planet.”While these are the first direct…

The James Webb Space Telescope — already famous for its mesmerizing images of the cosmos — has done it again. The telescope has captured the first unambiguous evidence of carbon dioxide in the atmosphere of a planet outside the Solar System. The finding not only provides tantalizing hints about how the exoplanet formed, it is also a harbinger for what’s to come as Webb studies more and more alien worlds. It was reported in a manuscript on the preprint server arXiv, ahead of peer review, and is expected to publish in …

The James Webb Space Telescope has, for the first time, detected evidence of carbon dioxide in the atmosphere of a planet outside the solar system. The evidence has been spotted on the exoplanet WASP-39 b, which was discovered in 2011. Located some 700 light-years from Earth, WASP-39 b is a hot gas giant planet that orbits a Sun-like star. According to NASA, the finding gives important insights into the formation and composition of the planet. In addition, it also suggests that the most powerful space telescope may be…

This illustration shows what exoplanet WASP-39 b could look like, based on the current understanding of the planet.WASP-39 b is a hot, puffy gas giant with a mass 0.28 times Jupiter (0.94 times Saturn) and a diameter 1.3 times greater than Jupiter, orbiting just 0.0486 astronomical units (4,500,000 miles) from its star. The star, WASP-39, is fractionally smaller and less massive than the Sun. Because it is so close to its star, WASP-39 b is very hot and is likely to be tidally locked, with one side facing the star at all…

The James Webb Space Telescope has clearly detected carbon dioxide in the atmosphere of an exoplanet for the first time. The find marks a milestone for the telescope’s goal of analyzing distant planets, which could eventually help discover signs of extraterrestrial life.One of James Webb’s key science goals is to study the composition of the atmosphere of exoplanets, with the hopes of ultimately finding ones that could host life. The main method the telescope uses to do this is transmission spectroscopy.Essentially, every…

Webb Space Telescope has detected “unequivocal” evidence of carbon dioxide in a distant exoplanet’s atmosphere, according to a European Space Agency release. According to the ESA, “it is the first clear, detailed, indisputable evidence” of carbon dioxide in a planet outside of our solar system.The world is a gas giant—similar to Jupiter—about 700 light-years away. It’s called WASP-39 b and was first discovered in 2011, but only now were scientists able to train the Webb Telescope’s remarkable spectroscopic powers on the…

Astronomers may have discovered the youngest exoplanet ever detected. They detected the world in question around the adolescent star AS 209 using the Atacama Large Millimeter/submillimeter Array in Chile. Of course, detecting a signal from the planet doesn’t prove its existence. As such, James Webb will now target that area and look for more evidence the planet exists.
