What can star variability—changes in a star's brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted for publication in The Astronomical Journal ...

The habitable zone is just the start. Scientists now focus on exoplanet atmospheres to find signs of life beyond Earth. Discover how carbon cycling, greenhouse gases, and NASA's upcoming Habitable ...

For decades, the search for alien life has revolved around a narrow ring around stars where liquid water could exist on a planet’s surface. That “habitable zone” remains important, but astronomers are ...

Have scientists finally confirmed the existence of the first exomoon? This is what a study released on the preprint server ...

A planet's habitability is determined by a confluence of many factors. So far, our explorations of potentially habitable ...

HMC is a natural electromagnetic radiation that occurs in the frequency range of 600-1700 kilohertz (KHz), which is much lower than the frequencies used by conventional radio stations.
