Tapes containing the original, high-quality transmission of the Apollo 11 moon landing were wiped after being quietly shelved in an unmarked storage area by NASA. While other recordings of the historic 1969 mission survived, the revelation that at least some moon landing video disappeared has fueled wild conspiracies that NASA has been covering up what astronauts saw or even that the whole mission was faked.

It was the summer of 2020, and researcher Walter Crist was wandering around the exhibits inside a Dutch museum dedicated to the presence of the ancient Roman empire in the Netherlands. As a scientist who studies ancient board games, one exhibit stuck out to Crist: a stone game board dating to the late Roman Empire. It was about eight inches across and etched with angular lines that roughly formed the shape of an oblong octagon inside a rectangle.

At the time of the alignment, Greg Brown, an astronomer at the Royal Observatory Greenwich, told PA Media: Groups of three, four or even five planets being visible aren't uncommon, regularly appearing throughout each year But the more planets are involved, the more things need to be aligned to be visible at once. According to Nasa, multi-planet viewing opportunities can last from weeks to more than a month, as planetary movements are slow and gradual.

The gas giant's shape and size, previously known only from data collected more than 45 years ago, have been updated at last. The biggest planet in the Solar System just got smaller and flatter.

Researchers have detected rising temperatures, bubbling gases and unusual sulfur formations inside Mexico's El Chichón volcano, also known as Chichonal. The changes were recorded by scientists from the National Autonomous University of Mexico (UNAM) during monitoring between June and December 2025. The volcano last erupted in 1982, killing at least 2,000 people in one of Mexico's deadliest volcanic disasters. Scientists observed elevated heat, shifting crater-lake chemistry, and gas emissions including hydrogen sulfide and carbon dioxide, which can be hazardous in high concentrations.

The biochemist revealed his results on February 2 on Spain's most-watched television program, El Hormiguero. The host, Pablo Motos, proclaimed: It's a miracle. Colleagues at his own center criticize Barbacid for not better explaining his conflict of interest. He and his colleagues Carmen Guerra and Vasiliki Liaki have applied for a patent for the commercial exploitation of their experimental therapy, should it ever become a reality.

In the pristine High Arctic sits the Kitsissut island cluster, also known as the Carey Islands, nestled between northwest Greenland and northeast Canada. The surrounding seas are perilous, and traveling there is difficult even with modern boats. But new archaeological evidence suggests ancient humans managed to sail to the islands, too. Early settlers lived on the islands between 4,500 and 2,700 years ago.

From changing size, to crushed immune systems and childbirth complications, humanity colonizing Mars could come with a host of problems for the human body. Elon Musk believes Mars settlement is possible by 2050, but there are considerable challenges and questions that still need to be answered before a permanent presence on the planet can be seriously considered, Rice University professor Scott Solomon believes.

Auroras are nature's most special light show: when charged particles from the sun hit our atmosphere, they can generate bright colors that dance across the night sky near the Earth's poles. Auroras can come in various forms, including bands, rays, patches and more. But why auroras form these patterns is less clear. Now, researchers say they've identified the battery that powers at least one kind of auroraaurora arcs.

Plenty of asteroids can survive their fiery plunge through the Earth's atmosphere. If they're big enough, they can prove incredibly destructive, like the 60-foot Chelyabinsk meteor that exploded over the southern Ural region in Russia in 2013, releasing a blast equivalent to 30 times the energy of the atomic bomb that was dropped on Hiroshima. And in case an even larger space rock were to ever threaten humanity, we'd have to get creative to keep it from colliding with our planet.

Venus has long been known as Earth's evil twin. While they both are roughly the same size and formed in the same inner region of the solar system, Venus is far less hospitable to life as we know it. Its surface temperatures can reach over 900 degrees Fahrenheit. Its clouds are made of sulfuric acid, and its surface atmospheric pressure is almost 100 times that of Earth, the equivalent of being 3,000 underwater.

In a white and sterile office that could belong to any one of the warehouses that dot this industrial strip between Brisbane's airport and horse-racing precinct, a young woman is engrossed in a puzzle. Only this puzzle comprises, perhaps, three different sets, each almost (but not quite) identical to the other and none likely to be completed. Emily Totivan wears blue plastic gloves. She is an archaeology student helping to catalogue artefacts.

Alongside the obvious nasal hairs that a few people choose to trim, all of us have cilia, or microscopic hairs in our noses that can move and sense things of their own accord. And so if anything gets trapped by the cilia, that triggers a reaction to your nerve endings that says: Right, let's get rid of this.' And that triggers a sneeze.

The Crew-12 astronauts will soon make their way to the ISS, joining the three remaining spacefarers on board after the previous mission was cut short due to a medical concern. NASA was originally planning a February 15 launch date for the mission, but it has moved it up to February 11. It's now targeting a liftoff of no earlier than 6:01 AM Eastern that day from Cape Canaveral in Florida.

The big news in rocketry this week was that NASA still hasn't solved the problem with hydrogen leaks on the Space Launch System. The problem caused months of delays before the first SLS launch in 2022, and the fuel leaks cropped up again Monday during a fueling test on NASA's second SLS rocket. It is a continuing problem, and NASA's sparse SLS launch rate makes every countdown an experiment, as my colleague Eric Berger wrote this week.

The first stage, of course, would be fully reusable. But what about the upper stage of New Glenn, powered by two large BE-3U engines? Around the same time, in the early 2010s, SpaceX was also trading the economics of reusing the second stage of its Falcon 9 rocket. Eventually SpaceX founder Elon Musk abandoned his goal of a fully reusable Falcon 9, choosing instead to recover payload fairings and push down manufacturing costs of the upper stage as much as possible.

Okay, first thing first: the universe is in fact expanding. We've known this for more than a century now, and it's the basis for modern cosmology. This idea is called the big bang modelwhich is an unfortunate name because it brings to mind a cosmos expanding like an explosion, with galaxies moving away from each other through space like shrapnel. But in fact space itself is expanding, and that's different.

"Granted, "[p]lants have extensive and well established mechanisms of communication, with that of volatiles being the most well studied and understood," he added. "There is also growing recognition that root exudates play a role in plant-plant interactions, though this is only now being deeply investigated. Nothing else, communication through mychorriza, has withstood independent investigation."

A team of geologists has found for the first time evidence that two ancient, continent-sized, ultrahot structures hidden beneath the Earth have shaped the planet's magnetic field for the past 265 million years. These two masses, known as large low-shear-velocity provinces (LLSVPs), are part of the catalog of the planet's most enormous and enigmatic objects. Current estimates calculate that each one is comparable in size to the African continent, although they remain buried at a depth of 2,900 kilometers.

Researchers at the Norwegian University of Science and Technology and the University of Tokyo have made a prototype of botanical cement made of desert sand and plant-based additives in hopes that it can be used to build houses and roads. Once mixed, the team adds tiny pieces of wood together and presses them all with heat to produce the cement.

About 45 minutes prior to landing in Honolulu on Dec. 18, 2022, the pilots of Hawaiian Airlines Flight 35, a widebody Airbus A330, saw a white, plume-like cloud swiftly rising vertically ahead of them, caused by a storm cell. Moments later came a hard jolt. Then the airplane dropped rapidly, creating a brief free-falling sensation inside the cabin. Phones, water bottles, blankets and service carts lifted into the air. Passengers were affected as well, with some held down by a seatbelt while others rose upward.

I killed seven houseplants before I discovered the secret: I was literally loving them to death. Every morning, I'd check on them with my watering can in hand, convinced that more water meant more love. Turns out, some plants thrive when you basically ignore them. In fact, there's one particular plant that actually prefers when you forget it exists for weeks at a time.

Real estate with ocean views, stunning mountain vistas, and wide-open green spaces sell at premium prices because humans find those settings pleasing [1-5]. Certain color combinations in fashion-such as brown and forest green-blend harmoniously, while others, such as hot pink and orange, clash. And our eyes like certain proportions in visual objects (like buildings and human faces) but not others.
