Iran almost certainly had some role in a major attack on an oil production facility in Saudi Arabia, according to independent analysts reviewing the available evidence.

The question is how big.

The attack came on Sept. 14. Multiple drones or missiles struck Saudi Aramco's Abqaiq facility, causing massive damage and crippling the nation's oil production. The production of 5.7 million barrels of crude oil per day had to be suspended, according to the company.

A major oil storage terminal on Grand Bahama Island was damaged by Hurricane Dorian and has leaked oil into the surrounding environment, raising concern that the oil could damage local reefs and wildlife.

The South Riding Point facility sits on the shore of the island's eastern side and is home to 10 giant storage tanks capable of holding up to 6.75 million barrels of crude, according to Equinor, the company that runs the facility.

The first thing Melissa Hanham did when she saw President Trump's tweet last week was take a screen grab.

"My reaction was to immediately save the image to my phone just in case it got taken down," she says.

The wording on the tweet was cryptic: "The United States of America was not involved in the catastrophic accident during final launch preparations for the Safir [space launch vehicle] Launch at Semnan Launch Site One in Iran," the president said. "I wish Iran best wishes and good luck in determining what happened at Site One."

Timothy Koeth's office is crammed with radioactive relics — old watches with glowing radium dials, pieces of melted glass from beneath the test of the world's first nuclear weapon.

But there is one artifact that stands apart from the rest: a dense, charcoal-black cube, 2 inches on a side. The cube is made of pure uranium metal. It was forged more than 70 years ago by the Nazis, and it tells the little-known story of Germany's nuclear efforts during World War II.

Satellite imagery shared exclusively with NPR shows that an Iranian rocket appears to have exploded on the launch pad Thursday.

Iran has crossed another line set in the 2015 nuclear deal between it and major world powers.

According to state media, Iran has begun enriching uranium above levels enshrined in the agreement. The move sends a signal that Iran is losing patience with a deal that has not provided the economic relief promised, more than a year after the United States withdrew from the agreement.

Iran is on the verge of crossing a key line included in the nuclear deal it reached with the U.S. and other powers in 2015. As soon as Thursday, it's expected to announce that its uranium stockpiles have exceeded limits set by the deal.

Victoria Girgis was leading a public outreach session at the Lowell Observatory in Flagstaff, Ariz., when one of her guests noticed a string of lights moving high overhead.

"Occasionally, you'll see satellites, and they look kind of like shooting stars moving through the sky," Girgis says. "But this was a whole line of them all moving together."

In January, a group of high-level military commanders gathered at an air base in Yemen. It was far from the frontlines of the country's ongoing civil war.

Then, without warning, a small drone appeared out of the sky and exploded, spraying the group with shrapnel. According to news reports, the blast killed several, including the Yemeni government's head of military intelligence.

North Korea's newest missile has a striking resemblance to an advanced Russian design, according to experts analyzing images from a test of the weapon on Saturday morning.

The missile, which North Korea describes as a "tactical guided weapon," appears superficially to be nearly identical to Russia's Iskander missile — a highly accurate short-range weapon capable of striking targets more than 150 miles away.

On the outskirts of Riyadh, Saudi Arabia is building what it sees as the future of its energy production.

A secretive group of scientists who advise the U.S. government on everything from spy satellites to nuclear weapons is scrambling to find a sponsor after the Defense Department abruptly ended its contract late last month.

The group, known as the Jasons, will run out of money at the end of April. The Pentagon says that the group's advice is no longer needed, but independent experts say it has never been more relevant and worry the department is throwing away a valuable resource.

Earlier this year, President Trump laid out an ambitious plan for U.S. missile defenses. "Our goal is simple," Trump said during a speech in January. "To ensure that we can detect and destroy any missile launched against the United States, anywhere, anytime, anyplace."

To reach that goal, the administration's proposed new defense budget calls for hundreds of millions of dollars to study the use of lasers and particle beams in space. "It's new technology," the president said.

Except it isn't.

Early Friday morning, Japan's Hayabusa2 spacecraft detonated an explosive device over a small asteroid. The goal was to create a fresh crater that will later be studied by the spacecraft.

India says it shot down one of its own satellites, making it only the fourth country to test an anti-satellite weapon.

India's Prime Minister Narendra Modi announced the successful test on Wednesday in a rare national address and on social media. The test would "have a historic impact on generations to come," Modi said in a tweet.

The announcement comes just weeks before national elections in which Modi's party has tried to paint itself as being hawkish on national security.

A Spanish court says assailants who broke into North Korea's Embassy in Madrid last month later fled to the U.S.

According to new documents unsealed on Tuesday, the perpetrators of the attack included a U.S. citizen and another resident. The leader of the plot fled via Lisbon to Newark, N.J., and offered stolen material to the FBI in New York.

The Missile Defense Agency says it has conducted another successful test of its ground-based interceptor system.

Monday's test involved a missile carrying a dummy warhead fired from Kwajalein Atoll in the Pacific Ocean toward the U.S. West Coast. Sensors tracked the missile as it flew, and then two interceptors were launched from Vandenberg Air Force Base in California.
