New Habitable Planet Discovered 35 Light-Years Away! Exploring the Possibility of Extraterrestrial Life: A New Star in the Habitable Zone — The Fifth Super-Earth Demonstrates the Diversity of the Universe

1. Overview of the Discovery—The Impact of Being "35 Light-Years Away"

On July 31, 2025, Brazil's news site UOL Tilt reported "A Potentially Habitable Planet Close to Earth Discovered," sparking excitement among astronomy enthusiasts worldwide. The star of the show is the fifth planet L 98-59 f in the red dwarf system L 98-59

. The distance of 35 light-years from Earth is practically "next door" on a galactic scale.

2. What is the L 98-59 System?

L 98-59 is an M3-type dwarf star with a mass of 0.3 solar masses, located in the direction of Pisces. In 2019, TESS discovered the first three planets, followed by a fourth in 2021, and now the system is confirmed to have five planets. Notably, four of these planets are diverse, with volcanic and water worlds.EarthSky

3. Observation Methods—A New World Unveiled by "Data Mining"

The team reanalyzed old data from HARPS and ESPRESSO using a proprietary algorithm to extract non-transiting planets from stellar velocity variations. The precision improved by a factor of two, leading to the derivation of mass and an orbital period of 23 days. This AI-like approach to past data is a model case for maximizing outcomes while minimizing observation costs.

4. Scientific Significance—The Possibility of "Liquid Water" and the Super-Venus Concern

L 98-59 f receives 1.02 times the stellar light compared to Earth. The theoretical temperature ranges from 273 to 300 K, and if atmospheric pressure is adequate, oceans could be maintained. However, if the mass is large and volcanic activity is strong, it could become a "Super-Venus." If the James Webb Telescope detects water vapor or CO₂ through transmission spectroscopy, the potential for life could be rapidly assessed.WIREDSpace

5. Reactions on Social Media—A Mix of Enthusiasm and Caution

 

• X (formerly Twitter)

  • WIRED Science's official account called it a "game-changer in the search for extraterrestrial life."X (formerly Twitter)

  • Space influencer @345_space posted "#NextEarth is becoming a reality," quickly garnering 10,000 likes.X (formerly Twitter)

• Reddit /r/space

  • "Interesting, but 'potentially habitable' is an exaggeration" (DreamChaserSt)

  • "Just wordplay for headlines," said another skeptical voice (YsoL8)Reddit

• Instagram

  • Science account hellopakistan introduced it as "Say hello, L 98-59 f!" receiving over 650 ❤️.Instagram

  • In visual posts, a fantastical CG of a "blue glowing dot floating around a quiet red dwarf" went viral.Instagram

These varied reactions reflect the allure of "possible life" and the tension with scientific caution.

6. Future Roadmap—Webb, ELT, and Probes

The James Webb Space Telescope has already added this star system to its target list. Additionally, the European Extremely Large Telescope (ELT), scheduled for operation in the early 2030s, aims for direct imaging. Moreover, the "Life Finder" project is considering sending ultra-small probes to nearby systems using laser sails. A one-way mission to a destination 35 light-years away, taking about 20 years, is becoming a reality.

7. Conclusion—Is There Really a "Neighbor"?

L 98-59 f: Could it be a "second Earth," or is it a hot, acidic hell? The answer remains shrouded in mystery, but this achievement showcases a new era in planetary science driven by "data reuse" and "multi-wavelength collaboration." The joy and skepticism on social media serve as excellent educational material for scientific literacy. The true resolution lies in the hands of next-generation telescopes and our own patient observations.
