Planets in the Goldilocks zone may be snowballs

Seattle WA (SPX) May 15, 2018 Aspects of an otherwise Earthlike planet's tilt and orbital dynamics can severely affect its potential habitability - even triggering abrupt "snowball states" where oceans freeze and surface life is impossible, according to new research from astronomers at the University of Washington. The research indicates that locating a planet in its host star's "habitable zone" - that swath of space j

Planets in the Goldilocks zone may be snowballs

Modelling suggests life potential is determined by more than simply distance from a star. Richard A Lovett reports.
