Meet Einsteinium – The Mysterious, Glowing Element
Einst
einium might sound like something out of a science fiction story, but it is very real—and seriously fascinating. It’s a synthetic element, meaning it doesn’t occur naturally and has to be made in a lab. With its silvery-white metallic look, it is warm to the touch (don’t try it!). It is extremelyÌý radioactive.ÌýFun Facts:Ìý Einsteinium is so radioactive it glows with a visible blue light - it literally lights up! But it gets even weirder: the heat from its ownÌý radioactivity actually destroys its crystal structure, meaning it slowly self-Ìý destructs over time.

Einsteinium was first discovered in December 1952 by Albert Ghiorso and a team of scientists. ÌýThe discovery came from analyzing the fallout of the Ivy Mike nuclear test, which was the first-ever successful thermonuclear explosion, conducted on November 1, 1952, at Enewetak Atoll in the Pacific Ocean.
