Infrared measurements of TRAPPIST-1 c indicate that it is probably not as Venus-like as once imagined. NASA's James Webb Space Telescope has successfully measured the heat radiating from TRAPPIST-1 c, ...

A Carnegie-led team of astronomers detected the strongest evidence yet of an atmosphere around a rocky planet beyond our solar system. Their work, published in The Astrophysical Journal Letters, used ...

Add Yahoo as a preferred source to see more of our stories on Google. An artist’s rendering shows TOI-561 b with a thick atmosphere over a global magma ocean, supported by Webb observations indicating ...

Researchers have detected a thick atmosphere around a planet called 55 Cancri e, which is twice as big as Earth and classified as a super Earth. The atmosphere of 55 Cancri e consists of carbon ...

Could a planet that sizzles under constant stellar glare still wrap itself in a thick, protective atmosphere? For decades the answer seemed obvious-no. Yet NASA’s James Webb Space Telescope has now ...

It took a few attempts, but JWST has finally found strong evidence of an atmosphere around a rocky world outside our solar system. To add to the intrigue, this isn’t the planet’s original atmosphere — ...

For years, scientists have puzzled over how Mars lost the thick atmosphere it once had. That atmosphere was essential for liquid water to exist on the planet's surface, billions of years ago. Today, ...

Caption: This artist’s concept shows what the ultra-hot super-Earth exoplanet TOI-561 b could look like based on observations from NASA’s James Webb Space Telescope and other observatories. Webb data ...
