Explore how Earth would appear without life. Studies from Universe Today and Cornell University reveal atmospheric signals, surface conditions, and implications for exoplanet observations.

Scientists might have just found Earth's icy, distant cousin a few hundred million light-years away. HD 137010 b is one of ...

Beyond that, in the decades to come, we might be able to see the colours of an exoplanet’s surface, and determine if plant life might be present there. And then we can search for changes in a planet’s ...

How any Earth-sized exoplanets exist, and how do we find them? This is what a recent study published in The Astrophysical Journal Letters hopes to address | Space ...

An exoplanet's instellation flux, or insolation flux, describes the amount of solar energy that reaches the exoplanet's surface. It's measured in watts per square meter (W/m²). In the paper, the ...

The planets have been nicknamed Earth's seven sisters. — -- An international team of astronomers has discovered seven potentially habitable exoplanets — or planets outside our solar system — that ...

A newly discovered exoplanet, TOI-561 b, is shaking up conventional theories about planetary atmospheres. According to a recent study published in The Astrophysical Journal Letters, this ultra-hot ...

Scientists identify exoplanet candidate HD 137010 b, a possible Earth-size world orbiting a Sun-like star 146 light-years away ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

Beyond our solar system, sub-Neptunes — gassy planets larger than Earth but smaller than Neptune — reign as the most common type of exoplanet observed in our galaxy. Despite their prevalence, no such ...
