The Chernobyl disaster remains the world’s worst nuclear accident, displacing hundreds of thousands and reshaping global safety standards decades later.

The Chernobyl disaster occurred when technicians at the power station, near Pripyat in the north of Ukraine, then part of the Soviet Union, ran a test on reactor number four to simulate shutting it down during an electricity blackout.

Forty years ago, in April 1986, there was an explosion at the Chernobyl Nuclear Power Plant. It was the worst nuclear accident in history. Then the plant was in the USSR, it is part of northern Ukraine now.

Photographer Pierpaolo Mittica has been documenting the passage of time at the disaster site as clean-up crews, tourists, and war, come and go in a landscape still teeming with radiation. "We are just at the beginning of the story of Chernobyl.

The nuclear incident at Chernobyl spread radiation across Europe and led to political changes that played a role in the collapse of the Soviet Union.

Ideas have been floated for how the contaminated zone could bring economic benefits to Ukraine. But for the foreseeable future, it will be an army-controlled security belt.

Russia’s invasion deepens the saga of Ukraine’s Chernobyl Exclusion Zone. A woman who fled war and ended up there says, “We overcame radiation. We will overcome Russia, too.”

Chernobyl's worst day may have turned out to be a windfall for its wolves. As the 40th anniversary of the 1986 reactor meltdown rolled around on Sunday, scientists say wolf numbers in the Chernobyl Exclusion Zone are now about seven times higher than before the disaster,

The disaster that struck at the Chernobyl nuclear power plant in Ukraine, and the dogs and their offspring who survived, presented a unique research opportunity for a University of South

In the novel "When There Are Wolves Again" by E.J. Swift, the Chernobyl disaster and its legacy is extrapolated to a near future where natural habitats are depleted and precarious.

These 20 pictures capture the aftermath of the infamous 1986 Chernobyl incident—effects that are, in some cases, still felt today.
