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.

Peruvian presidential candidate proposes death penalty amid crime surge

Peru is facing an unprecedented surge in crime ahead of its presidential election scheduled for April 12, with violence fueled by extortion networks and a wave of contract killings linked to organized crime.

Police data show that 2,200 homicides tied to organized crime were recorded in 2025, while extortion complaints increased by 19%, underscoring the growing security crisis in the South American nation.

Amid this backdrop, presidential candidate Álvarez has proposed reinstating the death penalty if elected, arguing that extreme measures are needed to curb the violence.

To implement the proposal, Álvarez said Peru would withdraw from the American Convention on Human Rights—also known as the Pact of San José—which the country signed in 1978. The agreement prevents member states that have abolished capital punishment from reinstating it.

Currently, Peruvian law only allows the death penalty in cases of treason during wartime.

“We have to leave the Pact of San José and apply the death penalty in Peru because those miserable criminals don’t deserve to live,” Álvarez told AFP during a campaign stop at a market in Callao, the port city neighboring Lima.

“An iron fist against those criminals,” he added, proposing to declare hitmen as military targets.

During the campaign event, Álvarez walked through stalls selling vegetables, groceries, and fish, greeting vendors while musicians played cumbia music nearby.

The 62-year-old candidate, who spent more than four decades working in television as a comedian, is a newcomer to politics and is running for president under the País para Todos party.

Polls place him fifth in voter preference with nearly 4% support in a fragmented race featuring 36 candidates.

“I am an artist who has taken a step into politics to bring peace to my country,” Álvarez told reporters while surrounded by supporters.

FBI: Man who attacked Michigan synagogue died from self-inflicted gunshot

The man who died during Thursday’s attack on a synagogue in the United States suffered a self-inflicted gunshot wound to the head, according to the FBI.

FBI agent Jennifer Runyan told reporters that the suspect, identified as 41-year-old Lebanese citizen Ayman Mohamad Ghazali, shot himself at some point during the confrontation.

“At some point during the shooting, Ghazali suffered a self-inflicted gunshot wound to the head,” Runyan said during a press conference.

A spokesperson for the U.S. Department of Homeland Security confirmed the suspect’s identity.

Authorities said Ghazali drove a truck into the Temple Israel synagogue in West Bloomfield, located in the state of Michigan, on Thursday.

According to Michael Bouchard, sheriff of Oakland County, synagogue security personnel noticed the vehicle and confronted the suspect with gunfire.

Investigators said it would be premature to speculate about the motive for the attack, although reports indicate Ghazali recently lost relatives during Israeli strikes in Lebanon earlier this month.

“It would be irresponsible for me to speculate about his motive,” Runyan said.

Ghazali arrived in Detroit in 2011 on a spouse visa for U.S. citizens and obtained American citizenship in 2016, according to reporting by The New York Times.

He was the father of two teenagers, divorced from his wife in 2024, and had recently been working as a waiter.

The newspaper also reported that Ghazali attended a memorial service in the nearby city of Dearborn for relatives killed in the recent conflict, alongside other grieving family members from the Lebanese town of Machghara.

The Federal Bureau of Investigation said the incident is being investigated as an act of violence targeting the Jewish community.

A source from Michigan’s Lebanese-American community told CBS News that several of Ghazali’s relatives had been killed roughly ten days before the attack, leaving him deeply devastated.

Mexican Navy Ships Deliver Third Shipment of Humanitarian Aid to Cuba

Two logistics support vessels from the Mexican Navy — the ARM Papaloapan and the ARM Huasteco — docked again on Friday in the bay of Havana carrying a third shipment of humanitarian aid for Cuba.

The vessels had previously arrived on the Caribbean island on February 28 with a second cargo that included 1,200 tons of food, sent to help alleviate the country’s ongoing crisis, which has worsened following the U.S. oil restrictions affecting fuel supplies to the island.

Cuba’s deputy foreign minister Josefina Vidal confirmed the new shipment in a social media post.

“Two ships carrying a third shipment of aid from the Government and the people of Mexico for the Cuban people are now arriving at the port of Havana. Thank you Mexico for your solidarity with Cuba,” she wrote.

Previous aid shipments

During the second shipment, the Papaloapan transported 1,078 tons of beans and powdered milk, while the Huastecocarried 92 tons of beans and 23 tons of assorted food products collected by social organizations with support from the government of Mexico City.

In recent months, Mexico has become the largest provider of humanitarian aid to Cuba, sending around 2,000 tons of supplies, mostly staple foods and hygiene products, in the two shipments prior to Friday’s delivery.

The first shipment alone included 814 tons of food.

Cuba praises Mexico’s support

Hours before the ships arrived, Cuban President Miguel Díaz-Canel highlighted Mexico’s support during a televised appearance, describing the country as “a friendly and brotherly nation that has shown tremendous solidarity,”particularly praising Mexican President Claudia Sheinbaum.

Díaz-Canel also addressed reports suggesting that Mexican donations were being resold in state-run stores, dismissing them as a “disinformation campaign” promoted by right-wing groups.
