While parts of the Earth experienced a total lunar eclipse early Friday, a spacecraft on the moon captured the spectacle from a different perspective — a solar eclipse that appeared as a fiery ring in space.
The Blue Ghost lunar lander, which has been on the moon since the spacecraft's successful touchdown on March 2, captured images of the sun, Earth and moon lined up at around 4:30 a.m. ET, the private Texas-based company Firefly Aerospace announced Friday.
The lander captured what is known as the 'diamond ring' effect, which is when light from the sun peeks through right before totality — in this case when the Earth fully blocked the sun — and after.
Firefly Aerospace also shared footage made up of several images stitched together that the lander had rapidly captured during the solar eclipse. These images show the spacecraft taking on a deep red hue as the sunlight is refracted through the Earth's atmosphere, resulting in a shadow cast on the lunar surface.
'Firefly's Blue Ghost lunar lander had the rare opportunity to operate on the Moon and capture the first (high-definition) imagery of a total solar eclipse on March 14,' Will Coogan, Blue Ghost's chief engineer, said in a email. 'This is the first time in history a commercial company has ever been operational during an eclipse on the Moon, and we're incredibly proud of the imagery we've downlinked so far.'
The images came in after the lander's X-band antenna — the device used to beam data and images back from the vehicle — warmed up after facing cold temperatures during the darkness caused by totality, Firefly Aerospace posted on X.
'Operating for nearly 5 hours of darkness during a total eclipse is as challenging as operating during the lunar night — temperatures on the Moon can quickly drop below -100°C (minus 148 degrees Fahrenheit) and there's no sunlight to provide power, so the lander was solely running on battery power,' Coogan said in an email. 'But this team continues to raise the bar and make achievements that are incredibly difficult look easy.'
A spacecraft has captured an eclipse while on the moon's surface only one other time. In 1967, NASA's Surveyor 3 lander, which had been sent to gather data in preparation for the Apollo missions, captured a series of images that documented the first view of an eclipse from another celestial body.
The Blue Ghost lander has been documenting its journey through space since it left Earth on January 15, sharing breathtaking imagery of the moon and Earth. Next up, Firefly looks to capture the lunar sunset on Sunday.
During lunar sunsets, a mysterious phenomenon occurs when the moon's horizon glows, which is believed to be caused by sunlight scattering through floating electrostatic particles, according to NASA.
Firefly CEO Jason Kim has told CNN that he is looking forward to verifying this event.
'There's a phenomenon called the lunar horizon glow that only the Apollo 15 and 17 astronauts have seen with their eyes,' Kim said. 'We're going to be able to capture that in 4K-by-4K high-definition video and share that with the rest of the world.'
Besides sharing the imagery, Blue Ghost has 10 NASA science and technology instruments aboard as part of the space agency's Commercial Lunar Payload Services, or CLPS, initiative.
CLPS is part of NASA's broader Artemis program, which aims to land astronauts on the moon for the first time in more than 50 years. The instruments are currently working to collect data primarily on the moon's subsurface, such as lunar dust and regolith, the loose rocks and mineral fragments that cover the lunar surface.
Shortly after the sunset, the lander will continue to operate for several hours during the lunar nighttime before the period of darkness and cold temperatures are expected to cause the spacecraft to cease operations.

A Cracked Piece of Metal Self-Healed in Experiment That Stunned Scientists

File this under 'That's not supposed to happen!'. In an experiment published in 2023, scientists observed a damaged section of metal healing itself. Though the repair was only on a nanoscale level, understanding the physics behind the process could inspire a whole new era of engineering. A team from Sandia National Laboratories and Texas A&M University was testing the resilience of a small piece of platinum suspended in a vacuum using a specialized transmission electron microscope technique to pull the ends of the metal 200 times every second. They then observed the self-healing at ultra-small scales in the 40-nanometer-thick wafer of metal. Cracks caused by the kind of strain described above are known as fatigue damage: repeated stress and motion that causes microscopic breaks, eventually causing machines or structures to break. Amazingly, after about 40 minutes of observation, the crack in the platinum started to fuse back together and mend itself before starting again in a different direction. "This was absolutely stunning to watch first-hand," said materials scientist Brad Boyce from Sandia National Laboratories when the results were announced. "We certainly weren't looking for it. What we have confirmed is that metals have their own intrinsic, natural ability to heal themselves, at least in the case of fatigue damage at the nanoscale." These are exact conditions, and we don't know yet exactly how this is happening or how we can use it. However, if you think about the costs and effort required for repairing everything from bridges to engines to phones, there's no telling how much difference self-healing metals could make. While the observation is unprecedented, it's not wholly unexpected. In 2013, Texas A&M University materials scientist Michael Demkowicz worked on a study predicting that this kind of nanocrack healing could happen, driven by the tiny crystalline grains inside metals essentially shifting their boundaries in response to stress. Demkowicz also worked on this study, using updated computer models to show that his decade-old theories about metal's self-healing behavior at the nanoscale matched what was happening here. That the automatic mending process happened at room temperature is another promising aspect of the research. Metal usually requires lots of heat to shift its form, but the experiment was carried out in a vacuum; it remains to be seen whether the same process will happen in conventional metals in a typical environment. A possible explanation involves a process known as cold welding, which occurs under ambient temperatures whenever metal surfaces come close enough together for their respective atoms to tangle together. Typically, thin layers of air or contaminants interfere with the process; in environments like the vacuum of space, pure metals can be forced close enough together to literally stick. "My hope is that this finding will encourage materials researchers to consider that, under the right circumstances, materials can do things we never expected," said Demkowicz. The research was published in Nature. An earlier version of this article was published in July 2023.

Conspiracy Theorists Are Creating Special AIs to Agree With Their Bizarre Delusions

Conspiracy theorists are using AI chatbots not only to convince themselves of their harebrained beliefs, but to recruit other users on social media. As independent Australian news site Crikey reports, conspiracy theorists are having extensive conversations with AI chatbots to "prove" their beliefs. Then, they post the transcripts and videos on social media as "proof" to others. According to the outlet's fascinating reporting, there are already several bots specifically trained on harebrained conspiracy theories, including a custom bot designed to convince parents not to vaccinate their children. The news highlights a troubling trend, with countless ChatGPT users developing bizarre delusions and even spiraling into severe mental health crises, as we reported last week. Experts have warned that AI chatbots are designed to be incredibly sycophantic, predisposing them to agreeing with users even when doing so is clearly harmful. Much like delusions of spiritual awakenings, messianic complexes, and boundless paranoia, conspiracy theorists are finding the perfect conversational partner in tools like ChatGPT. Since they were trained on the open web — an enormous data set that includes unfounded conspiracy theories, like the belief that vaccines cause autism — they can easily be coaxed into furthering these theories. As Crikey reports, one chatbot called Neo-LLM was trained by a Texan anti-vaxxer using over 100,000 dubious articles from the far-right conspiracy theory news website Natural News. It's unclear how many users have downloaded the chatbot, but promotional videos have garnered tens of thousands of views. In short, it's an alarming trend that shows the dangers of powerful AI chatbot tech falling into the wrong hands. In particular, people suffering from mental health issues can be convinced they're talking to a real authority, rather than a parroting language model that continuously calculates the probability of the next word. That kind of delusion can have devastating consequences. As the New York Times reported last week, a 35-year-old man — who had previously been diagnosed with bipolar disorder and schizophrenia before becoming obsessed with ChatGPT — was shot and killed by police after he charged at them with a knife following a mental health crisis centering on the bot. Since AI chatbots have become incredibly effective at generating convincing-sounding answers, their ill use could have real-life implications. Researchers have shown that AI chatbots can easily be weaponized and taught how to spew an endless firehose of disinformation. With the Trump administration actively rolling back AI regulations and key politicians furthering anti-vaccine conspiracy theories themselves, the future looks bleak. Even tech companies have historically failed to implement effective guardrails to stop chatbots from hallucinating. However, some experts have pondered if the tech could be used for good as well. Last year, researchers at MIT found that chatbots can also be used to reduce the belief in conspiracy theories, a glimmer of hope as the internet becomes increasingly polluted with deranged, AI-generated claims.
