NASA, ESA, CSA, L. Hustak (STScI) The big aim, though, is for Webb to detect exoplanet atmospheres. The researchers were able to gather some data on the newly detected planet’s atmosphere and to rule ...

When a planet gets that close to its host star, it can have its atmosphere stripped away by the star’s heat and radiation. In the case of the recently discovered exoplanet LHS 475 b, JWST observed two ...

In August astronomers revealed they had used JWST to detect carbon dioxide on an exoplanet for the first time by watching for signs of the gas in the light of a gas giant planet’s host star filtering ...

The planet is rocky and almost precisely the same size as Earth, but whips around its star in only two days. Researchers ...

The data shows that the exoplanet is an Earth-sized terrestrial (not water covered) world, but it is not known if it has an atmosphere. “The observatory’s data are beautiful,” noted Erin May ...

Exoplanet LH 475b has a radius about 99 percent the size of Earth’s, but that rocky radius is surrounded by either a choking atmosphere of carbon dioxide — or the vacuum of space, according to ...

The search for biosignatures on exoplanets got a boost of energy when the James Webb Space Telescope began observations. One of the telescope’s science objectives is to characterize exoplanet ...

Furthermore, Webb’s capabilities allowed the team to attempt to characterize the exoplanet’s atmosphere and composition. “There is no question that the planet is there. Webb’s pristine data validated ...

Not only was NASA's James Webb Space Telescope able to identify the exoplanet but it was also able to detect a range of ...
