(CNN) — Astronomers are questioning the theories of planet formation after discovering an exoplanet that technically shouldn’t exist. The planet, about the mass of Neptune and more than 13 times as ...

When it comes to explaining how planets are formed, the protoplanetary hypothesis is the most widely accepted explanation. In simple terms, the donut-shaped disc of dust and gas around a star forms ...

A rocky planet beyond gas dwarfs in LHS 1903 indicates that planetary systems form in unexpected ways.

A new model developed by scientists from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) extends the theory of elastic phase separation towards nanoscopic structures. Such ...

A recent study published in Science examines exoplanet LHS 3154b that orbits its parent star in just 3.7 days but is 13.2 times as massive as the Earth with the star being nine times less than our Sun ...

A groundbreaking discovery in the field of exoplanet research is forcing scientists to reconsider long-held theories about how planets form. An international team of astronomers, led by the University ...

A pair of NASA spacecraft detected tiny variations in the Moon's gravitational pull, which may be the result of a dense layer sinking to the bottom. Reading time 2 minutes During its early years of ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...
