The world's first wooden satellite has been built by Japanese researchers who said their tiny cuboid craft will be blasted off on a SpaceX rocket in September.

Each side of the experimental satellite developed by scientists at Kyoto University and logging company Sumitomo Forestry measures just 10 centimeters (four inches).

The creators expect the wooden material will burn up completely when the device re-enters the atmosphere -- potentially providing a way to avoid the generation of metal particles when a retired satellite returns to Earth.

These metal particles could have a negative impact on the environment and telecommunications, the developers said as they announced the satellite's completion on Tuesday.

"Satellites that are not made of metal should become mainstream," Takao Doi, an astronaut and special professor at Kyoto University, told a press conference.

The developers plan to hand the satellite, made from magnolia wood and named LignoSat, to space agency JAXA next week.

It will be sent into space on a SpaceX rocket from the Kennedy Space Center in September, bound for the International Space Station (ISS), they said.

From there, the satellite will be released from the Japanese ISS experiment module to test its strength and durability.

"Data will be sent from the satellite to researchers who can check for signs of strain and whether the satellite can withstand huge changes in temperature," a Sumitomo Forestry spokeswoman told AFP on Wednesday.

Also on Tuesday, a rocket carrying a separate sophisticated satellite -- a collaboration between the European Space Agency (ESA) and JAXA -- blasted off from California on a mission to investigate what role clouds could play in the fight against climate change.

The EarthCARE satellite will orbit nearly 400 kilometers (250 miles) above Earth for three years.

A new study suggests that a tiny, icy world beyond Pluto harbors a thin, delicate atmosphere that may have been created by volcanic eruptions or a comet strike.

Just 300 miles (500 kilometers) or so across, this mini Pluto is thought to be the solar system's smallest object yet with a clearly detected global atmosphere bound by gravity, said lead researcher Ko Arimatsu of the National Astronomical Observatory of Japan.

“This is an amazing development, but it sorely needs independent verification. The implications are profound if verified,” said Southwest Research Institute's Alan Stern, the lead scientist behind NASA's New Horizons mission to Pluto and beyond. He was not involved in the study.

The finding offers fresh insight into our solar system’s farthest, coldest objects in a region known as the Kuiper Belt. Researchers used three telescopes in Japan to observe the object in 2024 as it passed in front of a background star, briefly dimming the starlight.

“It changes our view of small worlds in the solar system, not only beyond Neptune,” Arimatsu said in an email. Finding an atmosphere around such a small object was “genuinely surprising," he added, and challenges “the conventional view that atmospheres are limited to large planets, dwarf planets and some large moons.”

This so-called minor planet — formally known as (612533) 2002 XV93 — is considered a plutino, circling the sun twice in the time it takes Neptune to complete three solar orbits. At the time of the study, it was more than 3.4 billion miles (5.5 billion kilometers) away, farther than even Pluto, the only other object in the Kuiper Belt with an observed atmosphere.

This cosmic iceball’s atmosphere is believed to be 5 million to 10 million times thinner than Earth’s protective atmosphere, according to the study appearing Monday in the journal Nature Astronomy.

It’s 50 to 100 times thinner than even Pluto’s tenuous atmosphere. The likeliest atmospheric chemicals are methane, nitrogen or carbon monoxide, any of which could reproduce the observed dimming as the object passed before the star, according to Arimatsu.

Further observations, especially by NASA’s Webb Space Telescope, could verify the makeup of the atmosphere, according to Arimatsu.

“That is why future monitoring is so important," he said. "If the atmosphere fades over the next several years, that would support an impact origin. If it persists, or varies seasonally, that would point more toward ongoing internal gas supply” from ice volcanoes.

Anne Boleyn won the heart of King Henry VIII, gave birth to one of the country's most well-known monarchs, and lost her head in 1536, but her appearance has continued to challenge art historians and online sleuths, according to BBC.

Now a computer science team believes they have discovered a previously unknown sketch of Boleyn by using facial recognition on a famous collection of Tudor portraits.

Boleyn became Henry VIII's second wife in 1533, but her reign was short-lived: approximately three years. She was accused of adultery, incest and treason and was executed.

All the painted portraits that exist of her were made after her lifetime, creating a mystery around what she actually looked like and making her appearance the subject of fascination and debate for centuries.”

The research team, led by the University of Bradford, said the new discovery is “exciting” and the methodology could be replicated to do more art detective work. But there is skepticism from within the art history community over the findings.

“We don't have a lifetime painted portrait of her that's absolutely secure, a wonderful painting that we can use as a reference point,” said Dr. Charlotte Bolland, a senior curator for research and 16th-Century collections at the National Portrait Gallery, who is independent from the new study.

She added: “Her reign wasn't necessarily long enough for an established iconography... and there is this tantalizing suggestion that perhaps some of her images might have been deliberately destroyed.”

Although there are no known surviving paintings made in her lifetime, there are a handful of lifelike, yet contested, depictions left. Including a preparatory sketch with her name on it.

It exists within a precious collection of drawings of Tudor court members by the masterful artist Hans Holbein the Younger, now held by the Royal Collection Trust.

Many modern art historians, such as Dr. Bendor Grosvenor, accept the label on this drawing is correct and that it is a surviving contemporary likeness of her.

But there is a counter argument, which claims it was mislabeled.

Despite these opposing theories, what is widely believed, based on written evidence, is that the collection of Holbein drawings does indeed contain a portrait of Anne Boleyn - somewhere.

Hoax calls involving alleged bomb threats and even claims of active shooters have prompted evacuations and closures at several zoos around the US in recent days, disrupting family plans and taxing public safety resources in some cities.

No explosives or real dangers have been found in the latest string of what authorities are describing as swatting incidents, The Associated Press reported.

The FBI considers swatting an increasing national problem. Aside from diverting resources, such calls can cost thousands of dollars per incident, endanger first responders and the public and can lead to federal charges.

In the latest case, police on Sunday swept the Akron Zoo in northeast Ohio after a threat led to the evacuation of visitors. Authorities gave the all-clear, but zoo managers opted to close for the rest of the day.

Just hours later, police were seen stationed outside the Cleveland Metroparks Zoo as visitors were evacuated due to a threat there. Some visitors took to social media, expressing anger that they had to leave.

The Columbus Zoo and Aquarium in central Ohio was evacuated on Saturday. Zoo president and CEO Tom Schmid told television station WCMH that due to similar threats at other zoos, employees had a safety drill last week and an exercise Saturday morning that helped prepare them for the emergency evacuation.

“This is part of life now around the country, around the world,” Schmid said, noting the uptick in such threats. “And so we have to make sure we’re vigilant.”

Threats also have been called in to zoos in Kentucky, Tennessee, Florida and Arizona.

Last year, dozens of hoax calls to college campuses across the US resulted in classes being canceled, campuses being locked down and in some cases students hiding under desks only to find out later that they were the victims of swatting.

Last week, federal prosecutors announced charges against a juvenile following a series of swatting calls aimed at universities and other institutions in Pennsylvania and elsewhere in August 2025. According to prosecutors, the defendant identified as a member of the cybercriminal group “Purgatory.”

The FBI has logged thousands of swatting incidents since creating a national database in 2023. Targets have included schools, public institutions and celebrities.

“Swatting is sometimes conducted as an act of revenge or a prank. It is a serious crime that has potentially dangerous consequences," the agency said in a statement Sunday. "Law enforcement personnel have been wounded responding to swatting incidents, and victims have been treated for injuries such as heart attacks as a result of such events.”
