This stability is a testament to the complex dynamics of binary star exoplanet systems. The orbital patterns of these planets may be compared to resonant orbital patterns, as seen in a 2013 study that ...

Astronomers studying a faint red dwarf star called LHS 1903 have found a four-planet system arranged in a sequence that no standard model of planet formation predicted. The system follows a ...

The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our solar system because it is similar in size to Earth, rocky, and resides in an area around its star ...

This ARKS gallery of faint debris disks reveals details about their shape: belts with multiple rings, wide smooth halos, sharp edges, and unexpected arcs and clumps, which hint at the presence of ...

Two investigations underscore the role of orbital instabilities in accounting for the diversity of planetary systems. As viewed from Earth (blue curves), the microlensing of a distant star by an ...

An international team of astronomers reports the discovery of a new exoplanet orbiting a sunlike star as part of the Next Generation Transit Survey (NGTS). The newfound alien world, designated NGTS-39 ...

The takeaway: An international team of astronomers has published a study on LHS 1903, a red dwarf star hosting a truly unusual planetary system. Unlike our solar system and many previously discovered ...

Astronomers have captured some of the most detailed images of debris discs—rings of leftover dust, gas, and rocks that circle a star—from fully formed, "teenage" planetary systems. And those images, ...
