Here is how subsidence craters are formed: an underground nuclear explosion gets set off and creates a hole underneath the ground. The ground collapses because nothing is supporting it anymore and then boom, giant crater. It is so gnarly to see because the ground looks like its melting into the core of the Earth.
The National Security Archive has published what is said to be the most comprehensive and detailed list of nuclear weapons targets and applied weapons strategy that has ever been declassified. The report includes details plans for purposefully targeting civilian populations and military infrastructure for the…
The nuclear bomb, that devastatingly powerful world killer of a weapon, has been around for 70 years. The first nuclear bomb—Trinity—was detonated in a test in New Mexico in 1945, a month later the US Army dropped nukes on Hiroshima and Nagasaki and the world was never the same. Here’s an interesting visualization…
The State Department has blocked the release of declassified documents about the CIA's role in the 1953 coup that overthrew Iran's democratically elected prime minister, due to the ongoing negotiations with Tehran over its nuclear program. But some historians think this is a dumb decision, that could actually backfire.
A newly declassified document obtained by a nuclear historian reveals that the Manhattan Project scientists who designed and detonated the first atomic bomb estimated that 10 to 100 enhanced "superbombs" would produce enough atmospheric radiation to wipe out the human race.
Although the Catholic Church has always opposed nuclear weapons, the Vatican reluctantly acknowledged during the Cold War that mutual assured destruction was the best-worst option for averting catastrophe. Today, a dramatic declaration from Pope Francis reversed that position.
The U.S. nuclear weapons program has been plagued by failings such as misplaced weapons, drug abuse and a cheating scandal. And now, the Energy Department's Office of the Inspector General tells us, some federal employees who transport these weapons have engaged in "unsuitable behavior" such as "uncontrolled anger."
Yesterday, negotiations over Iran's nuclear program failed to meet the deadline. Talks have been extended, but already an emerging chorus of "I told you so" says that it's pointless to negotiate with a fanatical religious regime that views nuclear war as holy martyrdom. It's time to put this myth to rest.
It came up the other night as dinner conversation. "Where do you think the next nuclear war will break out?" I asked. Everybody had an opinion.
On October 27, 1962, the captain of a Soviet submarine ordered a torpedo with a ten-kiloton nuclear warhead to be launched at a U.S. aircraft carrier. One man's decision prevented that order from being carried out—and his story is a cautionary tale about what could still happen in today's world.
Until the day he died, physicist Samuel Cohen declared that his invention, the neutron bomb, was a "moral" and "sane" weapon that would kill enemy combatants, while sparing civilians and cities. But, despite the support of fans like Ronald Reagan, this weapon of not-as-much mass destruction proved to be a hard sell.
Better late than never? Nearly 70 years after the Manhattan Project conducted the world's first atomic bomb test, the National Cancer Institute will soon begin a new investigation into the effects of the radioactive fallout on communities in New Mexico.
The Cold War is over, but you wouldn't know it looking at the current defense budget. The U.S. is spending hundreds of billions on new weapons systems to modernize its nuclear triad—and the Defense Department won't be able to pay for it without deeper cuts in conventional forces.
Henry Smith, a software engineer from Bristol, has been working on a game called — wait for it, 1980s movie fans — "Global Thermonuclear War." He was drawing concepts on a whiteboard, which proved to be unfortunate, since someone mistook it for a plan to nuke Washington, D.C.
The World War II program to develop an atomic bomb was the largest secret project ever undertaken by the U.S. government. But newly-declassified documents reveal how it hard it was to keep things secret as the weapon neared completion. Information leaks were everywhere, even in church sermons.
At the urging of Congress, military officials have begun considering East Coast sites for an anti-ballistic missile system that doesn't work and the Pentagon doesn't want. But members of Congress can't let such details stand in the way. Now states are vying to score the $4 billion allocated for this dubious effort.
For 17 years, James Doyle was a nuclear policy specialist at the Los Alamos National Laboratory. Then he wrote an article that made the case for getting rid of nuclear weapons. After that, his computer was seized, he was accused of releasing classified information, and then he was fired. What happened?
When NASA terminated the space shuttle program, it also deprived solid fuel manufacturers of their main customer. The result is a massive spike in propellant prices, which is increasing the cost of the U.S.-UK Trident nuclear program.
An unclassified excerpt of a Defense Department document reveals a subtle, but significant, change in language, which suggests that Iran's intercontinental ballistic missile technology does not pose an imminent threat to the U.S.
The Russian Ministry of Defense has announced that its only geostationary early-warning satellite — the Cosmos-2479, launched two years ago — is no longer functioning. With just two other observation satellites left in orbit, the chances of a false-alarm nuclear attack just escalated.
