A new machine learning model has predicted that there are 44 Earth-like planets in other star systems in the Milky Way galaxy, with researchers from Switzerland claiming that the algorithm at the core ...

Southwest Research Institute scientists propose a new model for the formation of compact exoplanetary systems that contain multiple rocky planets in tight orbits around their star. In this model, ...

OK, first, let’s get the name out of the way. Scientists have cataloged this exoplanet as PSR J2322-2650 b. It’s called that because it orbits a pulsar (a rapidly rotating neutron star) designated PSR ...

A slew of recent studies have used computer simulations to model the hypothetical conditions on rocky exoplanets with exotic orbits and spin states. What they show is that, contrary to the standard ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Hot Jupiters, giant planets that circle their stars in just a few days, have long defied simple explanations of how planetary systems grow and evolve. A new tidal “clock” hidden in their orbits is now ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...
