After decades of searching, astronomers might finally be on the verge of discovering thefirst confirmed exomoon, a natural ...

A group of astronomers claim they have found the first exomoon in the universe. While we know about around 6,000 exoplanets, an exomoon has never been found. That might soon change if the latest ...

After decades of searching, astronomers may have finally stumbled upon the first moon known to exist beyond our solar ...

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 ...

China search for Earth 2.0 leads a bold 2026–2030 space plan to probe the early universe, our Sun, and Earth-like exoplanets.

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to ...

Exoplanet scientists are eagerly awaiting the discovery of an atmosphere around a terrestrial exoplanet. Not a thin, tenuous, barely perceptible collection of molecules, but a thick, robust, ...

An exoplanet is what we call planets that exist outside of our own solar system. The first one was discovered in 1992, but as we get more powerful and precise telescopes and instruments, scientists ...

Stronger links between researchers who work on Earth’s and other planets’ atmospheres, and between the experimental, modelling and observational communities, will help to interpret the astronomical ...

Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have ...

Exoplanets are planets outside Earth's solar system. In 1995, a gas giant named 51 Pegasi b, which orbits a star similar to Earth's sun, etched its name in history as the first exoplanet ever ...
