Deep in the older, denser reaches of the Milky Way, there is a red dwarf star that shouldn’t exist — or at least, its family ...

A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.

The planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than the familiar one by which most systems grow ...

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...

A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover a planetary system that turns our understanding of planet formation upside ...

A network of powerful ground-based telescopes captured rare starspot-crossing events on TOI-3884b, revealing cooler patches on the star’s surface and rapid changes tied to its rotation. By combining ...

The Panel on Giant Planet Systems is one of six panels providing topical input to the Planetary Science and Astrobiology Decadal Survey Steering Group. This panel will discuss the role played by ...
