Don’t worry, this magma is cool to the touch.
a team of scientists at Cornell University took existing atmospheric and surface composition data to understand the mantles—or the interior—of 16 different exoplanets by modeling and synthesizing them here on Earth. They were able to create and cool artificial lava from other distant locales in our universe inside the lab, no volcanic eruption required.
Given that exoplanets are difficult to reach by even our farthest traveling space probes, there have rarely been experimental studies done on these faraway worlds, sayslead author of the study and engineering professor at Cornell University who studies geochemistry and volcanology.
Before the dawn of its glittering blue oceans and towering green forests, Earth too was a lava planet—molten and uninhabitable. At one point in its 4.5 billion-year lifetime, the planet might have resembled the hellish landscape of other super-sized Earths, like
