"This is just one sliver of data that Webb is providing us, using the NIRISS instrument specifically." "We've been able to use other telescopes to explore exoplanet atmospheres in the infrared, but not to this level of detail," Knicole Colón, an astrophysicist at NASA's Goddard Space Flight Center in Maryland, said. ![]() And Webb's new data offers scientists more data than ever before about that strange atmosphere. The only known cloudless planet, WASP-96 b has been an enigma and a prime target for further study since its discovery in 2013. It orbits its star every 3.4 days, and has a unique, cloudless atmosphere made largely of sodium. The gas giant world, about half the size of Jupiter, is the closest of the newly revealed objects, at about 1,150 light-years away. The final piece of Webb's first public science results wasn't an image at all, but a spectrum - a representation of the amount of different wavelengths of light emitted by an exoplanet dubbed WASP-96 b. (Image credit: NASA, ESA, CSA, and STScI) "As we go into the center, we see kind of the surprise for us, which is - we knew this was a binary star, but we effectively didn't really see much of the actual star that produced the nebula, but now in MIRI, this star glows red because it has dust around it, so in MIRI, we got to see both stars very clearly," he added.Īn analysis of James Webb Space Telescope data identifies chemicals present in the atmosphere of the hot exoplanet WASP-96 b. The new images show the shells formed by that gas, Karl Gordon, an astronomer at the Space Telescope Science Institute, said during the event, as well as patches in the nebula where starlight shines through. Having blown off all its outer layers, the dying white dwarf star at the nebula's heart is unimaginably hot and releasing intense ultraviolet radiation, causing the gas around it to light up. It is a planetary nebula, or an expanding cloud of gas surrounding a dying star. ![]() In contrast, The Southern Ring Nebula is closer to Earth - a mere 2,000 light-years away.
