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 out some ...

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

The four dots are exoplanets, with the black disk obscuring their star, 133.3 light-years away from Earth. The partial circles are their orbital motions, a time-lapse compiled fro ...

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 ...

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

“The exoplanet community is just giddy at the ... of a gas giant planet’s host star filtering through the world’s atmosphere. Known as transmission spectroscopy, this technique is incredibly ...

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 ...
