NASA on Tuesday said it had succeeded in deflecting an asteroid in a historic test of humanity’s ability to stop an incoming cosmic object from devastating life on Earth.

The fridge-sized Double Asteroid Redirection Test (DART) impactor deliberately smashed into the moonlet asteroid Dimorphos on September 26, pushing it into a smaller, faster orbit around its big brother Didymos, said NASA chief Bill Nelson.

“DART shortened the 11 hour 55 minute orbit to 11 hours and 23 minutes,” he said. Speeding up Dimorphos’ orbital period by 32 minutes exceeded NASA’s own expectation of 10 minutes.

“We showed the world that NASA is serious as a defender of this planet,” added Nelson.

The asteroid pair loop together around our Sun every 2.1 years, and pose no threat to our planet.

But they are ideal for studying the “kinetic impact” method of planetary defense, in case an actual approaching object is ever detected.

DART’s success as a proof-of-concept has made a reality of science fiction — notably in films such as “Armageddon” and “Don’t Look Up.”

Astronomers rejoiced in stunning images of matter spreading out thousands of miles in the wake of the impact — pictures collected by Earth and space telescopes, as well as a mini satellite that had traveled to the zone with DART.

Pseudo-comet

Thanks to its temporary new tail, Dimorphos, which is 530-foot (160-meter) in diameter or roughly the size of a big Egyptian pyramid, has turned into a manmade comet.

But quantifying just how well the test worked required an analysis of light patterns from ground telescopes, which took a few weeks to become apparent.

The binary asteroid system, which was around 6.8 million miles (11 million kilometers) from Earth at impact, is visible only as a single dot from the ground.

Ahead of the test, NASA scientists said the results of the experiment would reveal whether the asteroid is a solid rock, or more like a “rubbish pile” of boulders bound by mutual gravity.

If an asteroid is more solid, the momentum imparted by a spaceship will be limited. But if it is “fluffy” and significant mass is pushed at high velocity in the opposite direction to impact, there will be an additional boost.

Never actually photographed before, Dimorphos appeared as a speck of light around an hour before impact.

Its egg-like shape and craggy, boulder-dotted surface finally came into clear view in the last few moments, as DART raced toward it at roughly 14,500 miles (23,500 kilometers) per hour.

Mass extinction

Very few of the billions of asteroids and comets in our solar system are considered potentially hazardous to our planet, and none are expected in the next hundred years or so.

But wait long enough, and it will happen.

The geological record shows, for example, that a six-mile wide asteroid struck Earth 66 million years ago, plunging the world into a long winter that led to the mass extinction of the dinosaurs along with 75 percent of all species.

An asteroid the size of Dimorphos, by contrast, would only cause a regional impact, such as devastating a city.

Kinetic impact with a spaceship is just one way to defend the planet, albeit the only method possible with current technology.

Should an approaching object be detected early, a spaceship could be sent to fly alongside it for long enough to divert its path via using the ship’s gravitational pull, creating a so-called gravity tractor.

Another option would be launching nuclear explosives to redirect or destroy an asteroid.

NASA believes the best way to deploy such weapons would be at a distance, to impart force without blowing the asteroid to smithereens, which could further imperil Earth.

FBI Warns of Possible Iranian Drone Attack on U.S. West Coast

The Federal Bureau of Investigation (FBI) has warned police departments in California about a possible Iranian plan to carry out a drone attack against the west coast of the United States, according to a report published Wednesday by ABC News.

The warning was issued through a memorandum sent to agencies participating in a Joint Terrorism Task Force, outlining the possibility of a surprise attack involving unmanned aerial vehicles launched from a vessel off the U.S. coastline.

According to the document, intelligence suggested that in early February 2026 Iran may have considered an attack against unspecified targets in California if the United States carried out airstrikes on Iranian territory.

However, the memo also noted that authorities lack additional details about the timing, method, specific targets, or individuals responsible for the alleged plan.

Reports cited by U.S. media indicate that the alert coincided with the start of a military offensive by the administration of Donald Trump against the Iran, a development that has heightened tensions across the Middle East.

Law enforcement sources with counterterrorism experience told the Los Angeles Times that the warning is part of a routine precautionary advisory based on information from the U.S. Coast Guard.

The sources emphasized that there is no credible indication of an imminent attack and no evidence that Iran currently has the capability to successfully carry out such an operation.

California is home to the largest Iranian community in the United States. According to the Migration Policy Institute, more than half of Iranian immigrants in the country lived in the state in 2019, including around 140,000 people in Los Angeles County alone.

The city also hosts a neighborhood widely known as “Tehrangeles,” where a large Iranian community began settling in the 1960s and continued to grow following the Iranian Revolution.

Trump Says Iran Is Welcome at 2026 World Cup but Warns of Security Concerns

The President of the United States, Donald Trump, said Thursday that the national football team of Iran is “welcome” to participate in the 2026 World Cup, although he suggested it might be safer for the team not to take part in the tournament.

“The Iranian national soccer team is welcome at the World Cup, but I really don’t think it’s appropriate for them to be there, for their own safety,” Trump wrote on his social media platform Truth Social.

His comments came a day after Iran’s sports minister, Ahman Donyamali, said that there are currently no conditions for the country to participate in the tournament following the killing of Iran’s Supreme Leader, Ali Khamenei, during a military offensive launched on February 28 by Israel and the United States.

“After the corrupt government killed our leader, there are no conditions that allow us to take part in the World Cup,” the Iranian official said. He added that the country has faced two wars in the past eight or nine months, resulting in thousands of civilian deaths, making participation in the tournament unlikely.

On Tuesday, the president of FIFA, Gianni Infantino, met with Trump at the White House.

Following the meeting, Infantino said that Trump reiterated that Iran’s national team would be allowed to compete in the FIFA World Cup 2026.

“We discussed the current situation in Iran and the fact that the Iranian team has qualified to participate in the FIFA World Cup 2026. During the conversation, President Trump reiterated that the Iranian team is, of course, welcome to compete in the tournament in the United States,” Infantino wrote on Instagram.

Iran issues threat to Trump as conflict escalates over Strait of Hormuz

The head of Iran’s Supreme National Security Council, Ali Larijani, threatened U.S. President Donald Trump on Tuesday, warning him to “beware of being eliminated.”

The Republican president had warned on Monday that he would strike Iran “very hard” if the Islamic Republic blocked oil shipments through the Strait of Hormuz, which has effectively been closed since the war began eleven days ago.

“Iran is not afraid of your empty threats. Others more powerful than you tried to destroy the Iranian nation and failed. Beware that you are not eliminated,” Larijani wrote on X.

Earlier, Iran’s Revolutionary Guards — the ideological military force of the Islamic Republic — also said their forces would move to block oil exports from the Gulf.

Meanwhile, Israeli Prime Minister Benjamin Netanyahu said Israel’s military offensive against Iran is far from over.

“Our aspiration is that the Iranian people free themselves from the yoke of tyranny; ultimately, that depends on them. But there is no doubt that with the measures taken so far we are breaking their bones, and we are not finished yet,” Netanyahu said in a statement.
