WASP-96 b is an exoplanet made up mostly of gas. The spectrum also shows evidence of clouds and haze, which were thought not to exist in WASP-96 b's atmosphere. Within the spectrum are highlights that indicate the presence of water molecules. JWST's observations of exoplanet WASP-96 b, a planet outside our solar system, is not an image but a spectrum of light.

Furthermore, scientists will be able to get a full count of these low-mass stars and account for their impact throughout the nebula. But by studying the jets revealed in the new image, scientists can understand how these stars are expelling gas and dust out of the cloud, thereby reducing the amount of material available to form new stars. Little is known about the numerous small, or low-mass, stars within nebulae. Scientists can also learn how star formation affects these clouds. The Webb telescope’s observations in nebulae like this will help scientists answer some of the unknown questions of astrophysics, like what determines the number of stars in a certain region and why do stars form with certain masses. However, if too much material is pushed away, it may prevent a star from forming. The pressure changes can cause the gas and dust to collapse, forming a new star in a process called accretion. As the edge of this region moves inward toward the gas and dust, it may encounter unstable areas. Within the Carina Nebula, a star-forming region known as NGC 3324 was captured by the Webb telescope in this image. ![]() ![]() Thanks to its infrared cameras, JWST can peer into these dusty regions of space, revealing incredible details previously unseen by other telescopes. ![]() Nebulae are massive clouds of gas and dust, some spanning up to hundreds of light-years across. Stellar nurseries, young stars, and protostellar jets, which are narrow, ultra-fast streams of gas emanating from baby stars, are all on display in this image of the Carina Nebula, a cloud of gas and dust approximately 7,600 light years away.

What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region NGC 3324 in the Carina Nebula.
