It is mostly based on estimates of habitability by the Habitable Worlds Catalog (HWC), and data from the NASA Exoplanet Archive. The HWC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo. [1] . There is also a speculative list being developed of superhabitable planets.

Aug 6, 2024 · Discovering the first true "alien Earth" is a long-held dream of astronomers — and recent exoplanet discoveries have shown that small, rocky worlds like our own are abundant in our galaxy.

Oct 1, 2024 · Far beyond the eight familiar planets in our solar system, countless bizarre and extreme worlds await discovery — and some have already been found. Thanks to rapidly advancing telescope...

Jul 31, 2024 · Researchers have identified some exoplanets that are promising. The artist's concept depicts Kepler-186f , the first validated Earth-size planet to orbit a distant star in the habitable zone—a range of distance from a star where …

Mar 23, 2025 · Red dwarfs, common hosts for habitable-zone exoplanets, are notorious for violent flares that could strip away atmospheres or irradiate surfaces. Now that we’ve got the basics covered, let’s blast off and visit some of the closest potentially habitable exoplanets.

Feb 13, 2025 · Around a star just 20 light-years from the Solar System, astronomers have confirmed the existence of what might be a habitable world. The exoplanet HD 20794 d is just under six times the mass of Earth, orbiting a Sun-like star at the right distance for liquid water to form on its surface.

Mar 10, 2025 · Explore an interactive gallery of some of the most intriguing and exotic exoplanets discovered so far. Learn more about every confirmed exoplanet — 5,800 and counting — in this continuously updated resource.

Mar 6, 2025 · Although the planet is located in the system’s habitable zone, it is too early to say whether it could host life. Its high mass and eccentric orbit make it a very different world from ours. Unlike most planets in the Solar System, HD 20794 d’s orbit is not circular but elliptical. ... Alien Super-Earth Planet Discovered Just 26 Light-Years ...

Mar 23, 2025 · This surprising availability of energy makes planets orbiting close to white dwarfs strong candidates in the search for alien life. This is especially true given the 7 billion years of potential ...

Feb 23, 2025 · Although it lies in the habitable zone, its elliptical orbit presents challenges in determining its true potential for life. Future telescopes may soon provide deeper insights into its atmosphere, making this one of the most exciting exoplanet discoveries in recent years.
