A new study compares young and old exoplanets to uncover how worlds shrink, migrate and evolve over time — offering insights ...

They then compared the occurrence rates of these planets using data from NASA's TESS, or Transiting Exoplanet Survey Satellite, for the younger population and from Kepler for the older population.

"There really is something very different about how these giant planets form versus how small planets like Earth form." ...

More than 60 years after the first debunked discovery of a planet orbiting Barnard’s Star, the closest single-star system to ...

Since the turn of the millennium, thanks to advancing technology, we have been in a golden age of exoplanet discovery. Space-based telescopes such as Kepler and the Transiting Exoplanet Survey ...

And Kepler-16 b, located roughly 250 light-years away, is the real deal. Discovered in 2011, this exoplanet defies the traditional solitary planetary orbit by circling two stars — much like the ...

The frequency of that stellar wobble reveals an exoplanet’s orbital period and distance from its star, and its strength provides an estimate of the unseen world’s mass. The observations ...

Astronomers have discovered two exoplanets around TOI-1453, a star about 250 light years away. These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from ...

A team of researchers led by Dr. Daniel Angerhausen, a Physicist in Professor Sascha Quanz's Exoplanets and Habitability Group at ETH Zurich and a SETI Institute affiliate, tackled this question ...
