Spanish-Led Team Confirms New Planet in Habitable Zone
A Granada-based team confirmed an inner lava-world and a second planet in the star’s habitable zone, with the outer world about twice Earth’s size.
- On Monday, August 31, 2026, the Andalusian Institute of Astrophysics confirmed the TOI-1752 system hosts two planets orbiting a red dwarf approximately 337 light-years from Earth using NASA's TESS satellite data.
- TOI-1752 b orbits in 0.94 days as an "extremely hot" lava world, while TOI-1752 c sits in the "optimistic habitable zone" with a 32-day orbital period. The contrasting pair provides a rare opportunity for atmospheric comparison.
- Researchers compare these planets orbiting the same M-dwarf star under identical stellar conditions; lead author Alberto Peláez Torres and 49 collaborators noted the system's paired nature resolves a methodological gap in atmospheric research.
- Atmospheric researchers plan to characterize both worlds using the James Webb Space Telescope and the European Space Agency's Ariel mission, scheduled for 2029 launch, with both planets ranked as high-priority targets.
- Scientists regard TOI-1752 c as a "twin" of K2-18 b, a sub-Neptune discovered a decade ago, establishing this system as a critical benchmark for understanding atmospheric retention around low-mass stars.

A blistering lava world and a larger planet sitting in the habitable zone have been confirmed orbiting the same red dwarf 337 light-years away, a rare pairing that has put the system near the top of astronomers' list for probing whether an alien world can hold an atmosphere.
The discovery could finally let scientists test whether distant worlds can hang onto their atmospheres—or lose them to the stellar winds of their parent stars.

Two new planets discovered outside Solar System. One of them could be like Earth
Spanish researchers have identified two exoplanets orbiting the red dwarf TOI-1752. One of them has emerged as a key target because it may support liquid water if its atmosphere is suitable.

El CorreoWith twice the size of the Earth and about 18oC of temperature, TOI-1752 c could have liquid water and atmosphere, maintains the Institute of Astrophysics of Andalusia
It is the TOI-1752 system, about 337 light years from Earth. To locate it, the TESS satellite, a NASA satellite, was used to detect decreases in the brightness of stars when a planet passes by.
