Nearby Earth-Sized Exoplanet HD 137010 b Sparks Habitability Debate

Astronomers analyzing Kepler data have identified HD 137010 b, a rocky, Earth-sized exoplanet orbiting a nearby K-type orange-dwarf star about 150 light-years away, with a 355-day year. Its Earth-like size and orbit make it a compelling habitability candidate, potentially aided by a CO2-rich atmosphere, but the planet’s temperature is expected to be very cold and only a single transit was observed. Follow-up observations—ideally three transits—are needed to confirm its existence and assess habitability, especially given potential tidal locking around cooler stars.

Earth-sized exoplanet HD 137010 b hints at a Mars-like world in its star’s habitable zone

An Earth-sized planet HD 137010 b, about 6% larger than Earth and 146 light-years away, orbits a sun-like star every ~355 days and has roughly a 50% chance of residing in its star's habitable zone. Its surface temperature would be more Mars-like due to the cooler, dimmer star, potentially below −70°C. The planet was detected via a transit captured by NASA's Kepler K2 mission and initially flagged by citizen scientists; confirmation requires additional transits, and its proximity makes it a prime target for future telescopes.

Pandora: NASA’s new star watcher to sharpen exoplanet hunt with Webb

NASA’s Pandora exoplanet telescope, launched Jan 11, 2026, will monitor target stars for long periods to map stellar activity and starspots that can distort exoplanet transits, enabling a joint Webb–Pandora approach to study exoplanet atmospheres. Smaller than JWST but designed for repeated observations (about 200 hours per target across ten revisits over a year), Pandora will help separate stellar noise from planetary signals and will operate in low Earth orbit with eventual control shifting to the University of Arizona, accelerating the quest to identify potentially habitable worlds.

Citizen Scientists Uncover Kepler Space Telescope's Final Planets in Archive Data

Citizen scientists sifting through archive data from NASA's Kepler Space Telescope have identified the last three exoplanets discovered by the telescope. The Kepler Space Telescope, which launched in 2009, spent four years monitoring stars for the dip in brightness caused by a planet passing in front. After a reaction wheel failure in 2013, the telescope conducted the K2 observing campaign until it ran out of fuel in 2018. Despite the lack of fuel, the telescope's last observation run provided enough data for citizen scientists to identify three potential planets, confirming two of them. The discovery highlights the historical importance of these planets, given the circumstances of their identification.

The Uniqueness of Our Solar System: A Space Anomaly?

The Uniqueness of Our Solar System: A Space Anomaly?

Our Solar System is unique compared to the thousands of exoplanets discovered so far, leading some to believe that it could be an outlier in the galaxy. Most exoplanets discovered are not conducive to life due to their size and proximity to their stars. Exoplanet science is limited by our technology and our imagination, and there could be many more types of planets out there that we cannot currently detect. As technology advances, we may discover thousands of worlds hidden from our current view, and our understanding of exoplanets may change drastically.

Discovery of Two Habitable 'Super Earths' Near Proxima Centauri.

Discovery of Two Habitable 'Super Earths' Near Proxima Centauri.

Two new planets, designated TOI-2095 b and TOI-2095 c, have been discovered orbiting a red dwarf star 137 light-years away using NASA's Transiting Exoplanets Survey Satellite (TESS). Both planets are in the habitable zone and have estimated masses of 4.1 and 7.5 Earths, respectively. Future observations with other instruments could help determine the composition of the planets and confirm whether they are rocky worlds or something else.

Eternal Planetary Systems: Building for Perpetuity.

A study published in MNRAS explores how a super-advanced civilization might pack a bunch of planets into the habitable zone of a single star. The team found that as many as 24 Earth-like worlds could be packed into stable horseshoe resonances, sharing a common habitable zone. Such a system could prove the existence of an advanced civilization if the orbits were aligned to pass in front of their star from our vantage point, and we could detect them as exoplanets using the transit method.
