Innovative technique for finding worlds
The Transiting Exoplanet Survey Satellite, operated by the United States space agency, now applies a method that accounts for relativistic effects to detect subtle variations in starlight.
Einstein’s contribution to the discovery
By modelling time dilation and light bending, researchers refined stellar light curves and identified a periodic dip indicative of an unseen planet.
Characteristics of the newly identified exoplanet
The body orbits a Sun‑like star roughly 200 light‑years away. Preliminary estimates suggest an Earth‑size radius and an orbital period of about 30 days.
Implications for exoplanet science
This approach expands the toolkit for locating small planets that were previously lost in data noise, complementing transit and radial‑velocity techniques.
Future prospects
- Follow‑up studies will target the planet’s atmospheric composition.
- The method will be applied to the entire TESS archive.
- Scientists anticipate a rise in detections of additional terrestrial‑size worlds.
