Uranus and Neptune May Be Rock-Dominated Planets, Study Suggests

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 missions will be essential to confirm what truly lies beneath the blue atmospheres of these mysterious outer worlds.

Iceland lost 750 sq km of glaciers over the last two decades due to global warming

Iceland's glaciers have lost around 750 square kilometres (290 square miles), or seven percent of their surface, since the turn of the millennium due to global warming, a study published on Monday showed. The glaciers, which cover more than 10 percent of the country's land mass, shrank in 2019 to 10,400 square kilometres, the study in the Icelandic scientific journal Jokull said. Since 1890, the land covered by glaciers has decreased by almost 2,200 square kilometres or 18 percent. But almost a third of this decline has occurred since 2000, according to the recent calculations by glaciologists, geologists and geophysicists. Experts have previously warned that Iceland's glaciers are at risk of disappearing entirely by 2200. The ice's retreat over the past two decades is almost equivalent to the total surface area of Hofsjokull, Iceland's third-biggest ice cap at 810 square kilometres. "Glacier-area variations in Iceland since around 1890 show a clear respo...
