Exoplanet systems as a research area investigate the formation, architecture, dynamics, and physical properties of planetary systems orbiting stars other than the Sun, integrating observational, theoretical, and computational approaches. The field encompasses detection techniques (e.g., transits, radial velocities, direct imaging, microlensing), characterization of planetary masses, radii, atmospheres, and orbits, and statistical studies of population demographics as functions of stellar type, metallicity, and environment. It also addresses disk–planet interactions, migration processes, multi-planet dynamics, and stability, with implications for planet formation theories, comparative planetology, and the occurrence and potential habitability of terrestrial and giant planets in diverse stellar contexts.
Could scientists find life in the clouds of exoplanet atmospheres? This is what a manuscripton the arXiv preprint server hopes to address as a team of researchers investigate how the biosignatures of microbes could be identified ...

In approximately 5 billion years, the sun will deplete its hydrogen fuel and collapse under its own gravity, becoming a white dwarf. Though Earth-sized, this dense remnant will retain much of the sun's gravitational influence.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers from the University of California, Irvine (UCI) and elsewhere, have discovered two new exoplanets orbiting M-dwarf stars. The newfound alien worlds are ...
Is anybody out there? Probably. Most stars have planets; we've discovered more than 6,000 exoplanets thus far, and the most basic statistics point toward the existence of countless potentially habitable worlds in the universe. ...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants of dead stars.
An instrument is set to improve the detection and direct imaging of planets outside our solar system by harnessing the power of liquid crystals. The Programmable Liquid-crystal Active Coronagraphic Imager for the DAG telescope ...
