Astronomers using the Gemini South telescope have confirmed that the atmosphere of a scorching exoplanet carries the same chemical fingerprint as its host star, providing the strongest direct evidence ...

A rocky exoplanet 48 light-years from Earth has offered the 'strongest evidence yet' that other planets besides Earth could be hospitable to life.

What can a 3D map of an exoplanet’s atmosphere teach astronomers about the planet’s formation, evolution, and composition? This is what a recent study published in Nature Astronomy hopes to address as ...

Astronomers have found some pretty wild exoplanets. Some are balls of lava the temperature of hell, one is partially made of diamond, and another may rain molten iron. However, not all exoplanets are ...

Exoplanets are planets that orbit stars other than the sun and thus exist outside the solar system. The word "exoplanet" ...

(Nanowerk News) Scientists using NASA’s James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our ...

The James Webb Space Telescope has separated the thermal glow of a rocky planet from the light of its star and used that ...

Hydrogen can react with other chemicals, and both it and helium can be lost to space. Venus, Earth, and Mars are thought to have second atmospheres, with their original hydrogen/helium envelopes ...

Astronomers discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was ...

While the celestial body seems to host three features that could make a livable environment—an atmosphere, a rocky composition and a temperature that could allow liquid water to sit on the surface—res ...

Conventional wisdom assumes the ratio of gases in a planet's atmosphere should match the ratio of gases in the natal disk that birthed it. For the first time, researchers compared gases in a ...

Meet Tylos: a gas giant 900 light years away and with a climate never seen before on any planet known to scientists. Reading time 3 minutes Astronomers have uncovered the secrets of an alien ...
