LONDON (IT BOLTWISE) – Astronomers have discovered three Earth-sized exoplanets in a binary star system using NASA’s TESS space telescope. This discovery could revolutionize our understanding of planet formation and stability in such systems. The exoplanets could even experience double sunsets, similar to Tatooine in Star Wars.

The discovery of three Earth-sized exoplanets in a binary star system known as TOI-2267 represents a significant development in astronomy. These planets were discovered using NASA’s TESS space telescope, which was specifically designed to search for exoplanets. The special feature of this system is that it is the first known binary star system in which planets transit around both stars.
The discovery contradicts previous theories that say binary star systems cannot support complex planetary systems due to their gravitational instability. However, the planets of TOI-2267 show that such systems can host stable planets. This opens new perspectives for studying planet formation and the stability of planets in dynamically complex environments.
In addition to TESS, the researchers also used other observatories such as SPECULOOS and TRAPPIST to characterize the planets more precisely. These observatories specialize in studying small exoplanets around cool and faint stars. The results of these observations could also be important for future missions such as the James Webb Space Telescope, which will be able to measure the masses, densities and possibly even the atmospheric chemistry of these planets.
The discovery of these exoplanets in a compact binary star system provides a unique opportunity to test the limits of planet formation in complex environments. This could greatly expand our understanding of the diversity of possible planetary architectures in our galaxy. The research results were recently published in the journal Astronomy & Astrophysics.
