Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, ...

A distant exoplanet might have an atmosphere similar to Earth's, early observations from the James Webb Space Telescope (JWST ...

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, ...

Astronomers are pulling back the curtain on two of the universe’s biggest mysteries: how planets are born and how invisible ...

Methane gas may signal an atmosphere or geological activity on a distant dwarf planet located at the outer edge of the Solar System. A research team led by the Southwest Research Institute has ...

There is much less water on the surfaces of distant planets outside our solar system than previously thought. These ...

Exoplanets are worlds outside our solar system. Just over three decades ago, the first exoplanets were confirmed by Aleksander Wolszczan and Dale Frail. Now, with the aid of Nasa spacecraft and ...

See composite views of the Cartwheel Galaxy captured by the James Webb Space Telescope. The galaxy is 500 million light years away and has also been imaged by Hubble Space Telescope, comparison shown ...

Although ‘steam worlds’ were first proposed about twenty years ago, they are now supported by observations. The James Webb Space Telescope has detected water vapor around several sub-Neptunes, with ...

NASA spotted a new moon almost at the border of our solar system. Back in 1986, a theory came up that this cosmic body could ...
