The last time we did a story on extrasolar planets (or exoplanets) in October, 2009, there had been 374 planets outside our solar system discovered. As of June 28, 2010 that number had risen to 464.
We present new ways to identify single and multiple moons around extrasolar planets using planetary transit timing variations (TTVs) and transit duration variations (TDVs). For planets with one moon, ...
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 ...
Even though the ingredients for life have been confirmed to be practically everywhere we look, the only world where we've definitively confirmed its existence is Earth. Exoplanet science has exploded ...
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 ...
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 ...
A team of astronomers from Germany, Bulgaria, and Poland has used a completely new technique to find an exotic extrasolar planet. The same approach is sensitive enough to find planets as small as ...
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 ...
