For the first time, scientists have definitively discovered an "invisible" alien planet by noticing how its gravity affects the orbit of a neighboring world, a new study reports. NASA's Kepler space ...

Astronomers from Germany, Bulgaria and Poland have used a completely new technique to find an exotic extrasolar planet. The same approach is sensitive enough to find planets as small as the Earth in ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Scientists from UNSW Sydney have located a potential new exoplanet—a planet that orbits a star outside of our solar system—using a technique known as "transit timing variation." In research ...

Following on from Paper I in our series (Xie 2012), we report the confirmation by Transit Timing Variations (TTVs) of a further 30 planets in 15 multiple planet systems, using the publicly available ...

Anew planet-hunting technique that was used to detect an exotic alien world maybe sensitive enough to help astronomers search for Earth-sized planets thatorbit other stars, according to a new study.

Figure 5. MEGNO stability maps superimposed on an upper mass-limit function of a hypothetical perturber. A MEGNO of around 2 indicates quasi-periodic (regular) orbits. A MEGNO of 5 or larger indicates ...
