Big Picture Science for April. 27, 2026: 40 Years After Chernobyl

Heavily damaged industrial building with its upper structure torn open. The image is black and white and shows a large rectangular complex viewed from above at an angle. The central portion has a huge gaping hole and the roof and upper levels are shredded, with twisted metal, exposed beams, and collapsed sections scattered around. Many exterior walls are broken away, leaving open window bays and jagged concrete edges. Nearby sections of the complex are partially intact but still show severe structural damage. A road or paved area runs along one side of the building, relatively clear compared to the chaotic destruction of the main structure.









Big Picture Science: 40 Years After Chernobyl

On April 26th, 1986, an explosion at the Chernobyl Nuclear Power Plant in the Soviet Union blasted a plume of radioactive debris a half mile into the sky, blanketing Europe. Witnesses described a laser of blue light eerily shooting up from the reactor core. Built to represent the bright future of nuclear power, Chernobyl instead became the biggest nuclear disaster in history. In the first of a two-part series, we retell the story of the accident, the role that design flaws and human error played, and the futile attempts at radiation containment. We also consider the long shadow the catastrophe cast over nuclear power, and the significant political fallout of the Soviet coverup; the Ukrainian vote for independence and the fall of the U.S.S.R.
