Uranus and Neptune may not be true ice giants after all. New research using advanced hybrid simulations suggests the distant planets could be dominated by rocky material rather than water-rich ices. The findings challenge decades of planetary models and may help explain the planets’ unusual, non-dipolar magnetic fields. Scientists say future dedicated spacecraft mis...

More than 6,000 exoplanets (planets orbiting other stars), one of the most rapidly expanding frontiers in science, have now been confirmed by astronomers. Their search of other worlds has been transformed within a span of thirty years, which started as a form of speculation, to accurate detection. However, in the midst of this wave of discoveries, scientists believe t...
