Scientists say X-rays from nuclear explosion may deflect asteroids from Earth
Scientists in Albuquerque, New Mexico, say potentially dangerous asteroids could possibly be deflected by exploding a nuclear warhead more than a mile from its surface and showering it with X-rays to send it in a different direction.
Previous methods, as seen in blockbuster movies like “Armageddon” and “Deep Impact,” involved blowing up a nuclear warhead on an asteroid or comet and shattering it into multiple pieces.
But scientists now say the method would change the space object from a lethal bullet headed toward Earth into a shotgun blast of multiple fragments.
Last year, the National Academy of Sciences released a report calling planetary defense a national priority, and according to an ongoing NASA sky survey, the threat is credible.
STADIUM-SIZED ASTEROID DEEMED ‘POTENTIALLY HAZARDOUS’ BY NASA, IS EXPECTED TO MOVE ‘RELATIVELY CLOSE’ TO EARTH

The sky survey found there are about 25,000 objects big enough to cause varying degrees of destruction to Earth, and only about a third of them have been detected and tracked, according to a press release from the Sandia National Laboratories in Albuquerque.
Many of the objects move invisibly in the sun’s glare. In 2013, a relatively small object created chaos in Russia while a larger asteroid is credited with ending the age of dinosaurs.
“To most people, the danger from asteroids seems remote,” Nathan Moore, a physicist at Sandia National Laboratories said. “But our planet is hit by BB-sized asteroids every day. We call them shooting stars. We don’t want to wait for a large asteroid to show up and then scramble for the right method to deflect it.”
Moore’s team conducted several experiments with Sandia’s Z machine, the most powerful pulsed-power machine on Earth, to monitor the deflection of synthetic asteroids hit by Z’s sudden shocks.

While the machine is on Earth, all experiments are affected by gravity, though Moore’s team was able to beat the inevitable force temporarily to create a better simulation of asteroids floating freely in space.
Moore’s experiments used a technique called X-ray scissors, which removed the skewing effect of friction and gravity for a few microseconds.
The X-ray scissors allowed the model to create the effect of redirecting a free-floating asteroid when hit by a series of nuclear-intensity explosions.
Although the experiments were done in a much smaller environment than space, they could be scaled to predict the effects of nuclear explosions on an actual asteroid.

“I started working through the logic of how I could deflect a miniature asteroid in a laboratory just like in outer space,” Moore said. “A key fact was that asteroids in outer space aren’t attached to anything. But in a lab, everything is pulled down by Earth’s gravity, so everything is held in place by its gravitational attachment to something else. This wouldn’t let our mock asteroid move with the freedom of one in outer space. And mechanical attachments would create friction that would perturb the mock asteroid’s motion.”
And that’s where the X-ray scissors came in. The method allowed scientists to release a mock asteroid the size of a tenth of a gram and made of silica, into the free space vacuum.
The material was suspended by foil eight times thinner than human hair, which vaporized instantly when the Z machine fired.
The silica was then left free-floating as the X-ray burst hit it.

“It was a novel idea,” Moore said. “A mock asteroid is suspended in space. For a one-nanometer fall, we can ignore Earth’s gravity for 20 millionths of a second as Z produces a burst of X-rays that sweeps over the mock-asteroid surface 12.5 millimeters across, about the width of a finger.
“The trick is to use just enough force to redirect the flying rock without splitting it into several equally deadly subsections advancing toward Earth,” Moore added, referring to a real intercept scenario like the recent NASA DART experiment.
The news comes just days after NASA monitored a “potentially hazardous” asteroid moving past Earth last Tuesday.
NASA told Fox News Digital that the rocky object, which has been named 2024 ON, is 350 meters long by 180 meters wide, which roughly equals 1,150 feet by 590 feet — larger than previous estimates.
NASA has deemed the asteroid “stadium-sized” and reported it was 621,000 miles away from Earth, which is considered relatively close. Davide Farnocchia, a navigation engineer at NASA’s Jet Propulsion Laboratory, told Fox News Digital that an asteroid of this size coming this close to Earth only happens every five to ten years.
Although the asteroid was close enough to Earth to be deemed a “potentially hazardous object,” Farnocchia said there is no chance the asteroid would hit Earth. The asteroid would need to be within a couple of hundred miles to be a concern.
The asteroid was one of five that would pass by Earth last week, but the other rocky objects were not expected to come nearly as close as 2024 ON. The four asteroids were between 1.1 to 3.9 million miles away from Earth, and three of the asteroids measured roughly 51 feet in diameter, which is the size of a house.

Long Beach will hold a pride festival this weekend after the one they originally had scheduled was canceled.
Long Beach city officials said the celebration was nixed after the nonprofit that organizes it, Long Beach Pride, failed to submit the required information for an event permit.
It was supposed to start on Friday and last through Sunday.
“Despite continued collaboration and multiple deadline notices, the City did not receive the required documentation needed to complete safety reviews, inspect critical event infrastructure, such as the stage, electrical systems and tent, and emergency exiting plans to ensure compliance with public safety standards,” the city of Long Beach said in a statement. “With event programming scheduled to begin on May 15 at 5 p.m. with Teen Pride and essential information still outstanding, there is no longer sufficient time to safely permit the festival this year.”
Officials noted that they were working to see if a “shortened event” could be held this weekend, and indeed, an agreement was reached to stage a one-day gathering on Sunday.
Billed as “Canceled? Never Heard of Her!” and emceed by comedian and drag queen Jewels, it will still bring the city’s LGBTQ community together after Sunday morning’s Long Beach Pride Parade, which was not canceled.
“Long Beach Pride weekend is a culmination of celebrations put on by our community, including our many vibrant restaurants, bars and businesses, and that will never change,” Long Beach Mayor Rex Richardson said in a press release issued late Saturday night. “Along with the Pride Parade, we are proud to join the party with this new event that reaffirms what this City has always stood for: that every person belongs here.”
“The festival may have been canceled, but Long Beach drag artists don’t cancel joy,” added Jewels Long Beach.
The one-day “Canceled? Never Heard of Her!” festival will take place at Bixby Park from noon to 7 p.m. Sunday. A free event, it will include music by several performers and a drag show.

L.A. Jewish institution among targets of foiled terrorist attack, U.S. officials say
A Jewish institution in Los Angeles was among the locations targeted in a recently foiled terrorism plot, U.S. Attorney for the Southern District of New York Jay Clayton announced this week.
The thwarted terrorist attacks were the result of the recent arrest of Mohammad Baqer Saad Dawood Al-Saadi, an Iraqi national and senior member of Kata’ib Hizballah, U.S. officials said.
“Mohammad Baqer Saad Dawood Al-Saadi, a commander for the terrorist organization, Kata’ib Hizballah, faces serious charges for his role in numerous attacks against U.S. interests across the globe, including his efforts to kill on U.S. soil,” Clayton said. “As alleged, for years, Al-Saadi committed himself to furthering the terrorist goals of Kata’ib Hizballah and the IRGC, two terrorist organizations dedicated to harming the United States and its allies.”
Al-Saadi recently attempted to carry out attacks in the U.S., officials said, including attacks at Jewish cultural places of interest in New York, Los Angeles and Scottsdale, Ariz.
“Al-Saadi attempted to disrupt American society through intimidation and violence,” a press release from the U.S. Attorney’s Office reads. “… Those who engage in or support terrorism against Americans and on U.S. soil should take note: the whole of the federal government is committed to dismantling terrorist organizations and bringing their members to justice.”
In a three-month period, Al-Saadi allegedly directed 18 terrorist attacks throughout Europe, including bombings, arson, and assaults targeting American citizens and points of interest. Prior to his arrest, national security officials say he was planning similar attacks on U.S. soil. Assistant Attorney General for National Security John A. Eisenberg said that Al-Saadi “presented a serious threat to our national security.”
The European attacks included the bombing of the Bank of New York Mellon, an American bank, in Amsterdam on March 15. On April 29, two Jewish men, one of whom was a dual U.S.-British citizen, were stabbed and seriously injured in London.
In 2020, Al-Saadi took to social media, calling for others to attack and kill Americans in retribution for the deaths of Iranian military officer Qasem Soleimani and Iraqi military commander Abu Mahdi al-Muhandis, U.S. officials said. In more recent months, Al-Saadi allegedly used social media to encourage the killing of Americans and Jews to further the terrorist goals of Kata’ib Hizballah and the Islamic Revolutionary Guard Corps.
“In or about February 2026, for example, AL-SAADI posted on one of his social media accounts a message in Arabic, which read in part, ‘Do not abandon the blood of your Imam of the time, oh Shiites of Iraq. Kill everyone who supports America and Israel. Do not leave any of them remaining. Civil and military targets, as well as voices of discord, kill them everywhere.’” U.S. officials said.
NYPD Commissioner Jessica S. Tisch confirmed that one of the U.S. targets was a Manhattan synagogue. On April 3, Al-Saadi allegedly spoke to an undercover law enforcement officer whom Al-Saadi believed could carry out attacks in the U.S. That same day, Al-Saadi allegedly texted the undercover officers photographs and maps showing the exact location of a prominent Jewish synagogue in New York City.
Officials have not said what specific locations in L.A. and Arizona were targeted by the terrorist group.
Al-Saadi now faces numerous charges for these crimes in U.S. court. If convicted, he could be sentenced to life in prison.
The case is under investigation by the FBI’s New York Joint Terrorism Task Force, which is comprised of investigators and analysts from the FBI, the NYPD, the FBI Washington Field Office, Counterterrorism Division, and more than 50 other federal, state, and local agencies. Investigators also received help from the Department of Justice’s National Security Division, Counterterrorism Section, the Office of International Affairs of the Justice Department’s Criminal Division, and U.S. Customs and Border Protection.
A man armed with a knife was shot by L.A. police officers responding to an assault with a deadly weapon call overnight, authorities said.
According to the Los Angeles Police Department, officers with the Hollenbeck Division responded to an apartment complex in the 3000 block of Glenn Avenue in Boyle Heights at 1:45 a.m. Saturday after callers reported a male suspect was armed with a knife and had just assaulted someone in the complex.
Arriving officers found the suspect in front of the residence, but he did not comply with officers’ commands to drop the weapon. He then advanced toward the officers and an officer-involved shooting occurred, LAPD confirmed.
“The suspect was struck by gunfire and remained non-compliant,” the LAPD Public Information Officer said on X early Saturday morning. “Officers deployed a 40mm foam round and ultimately took the suspect into custody.”
Video obtained by KTLA shows the man being loaded into an ambulance and taken to a hospital; officials said he was transported in stable condition, adding that his knife was recovered at the scene and booked as evidence.
No officers or community members were injured during the incident. The man’s name was not released.
