Planet Formation
Astronomers have identified a four-planet system around the red dwarf star LHS 1903 where the outermost planet is rocky, defying typical formation patterns. This discovery, led by researchers from McMaster University and the University of Warwick, challenges established theories on how planets develop. Observations from space and ground-based telescopes revealed the unexpected composition of the distant world.

A three-year research project funded by the National Science Foundation is underway to uncover the origins of eccentric warm Jupiters, massive gas giants with elongated orbits around their stars. Led by an astronomer at Northern Arizona University, the study aims to explain why these planets align precisely with their stars' equators despite their unusual paths. The findings could reshape understanding of planet formation, including our own solar system.
