Preparations for Next Moonwalk Simulations Underway (and Underwater)
On Sept. 9, 2025, NASA’s Solar Dynamics Observatory captured this image of the Sun.NASA/GSFC/Solar Dynamics Observatory It looked like the Sun was heading toward a historic lull in activity. That trend flipped in 2008, according to new research.
The Sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. Case in point: Since the 1980s, the amount of solar activity had been steadily decreasing all the way up to 2008, when solar activity was the weakest on record. At that point, scientists expected the Sun to be entering a period of historically low activity.
But then the Sun reversed course and started to become increasingly active, as documented in the study, which appears in The Astrophysical Journal Letters. It’s a trend that researchers said could lead to an uptick in space weather events, such as solar storms, flares, and coronal mass ejections.
“All signs were pointing to the Sun going into a prolonged phase of low activity,” said Jamie Jasinski of NASA’s Jet Propulsion Laboratory in Southern California, lead author of the new study. “So it was a surprise to see that trend reversed. The Sun is slowly waking up.”
The earliest recorded tracking of solar activity began in the early 1600s, when astronomers, including Galileo, counted sunspots and documented their changes. Sunspots are cooler, darker regions on the Sun’s surface that are produced by a concentration of magnetic field lines. Areas with sunspots are often associated with higher solar activity, such as solar flares, which are intense bursts of radiation, and coronal mass ejections, which are huge bubbles of plasma that erupt from the Sun’s surface and streak across the solar system.
NASA scientists track these space weather events because they can affect spacecraft, astronauts’ safety, radio communications, GPS, and even power grids on Earth. Space weather predictions are critical for supporting the spacecraft and astronauts of NASA’s Artemis campaign, as understanding the space environment is a vital part of mitigating astronaut exposure to space radiation.
Launching no earlier than Sept. 23, NASA’s IMAP (Interstellar Mapping and Acceleration Probe) and Carruthers Geocorona Observatory missions, as well as the National Oceanic and Atmospheric Administration’s SWFO-L1 (Space Weather Follow On-Lagrange 1) mission, will provide new space weather research and observations that will help to drive future efforts at the Moon, Mars, and beyond.
Solar activity affects the magnetic fields of planets throughout the solar system. As the solar wind — a stream of charged particles flowing from the Sun — and other solar activity increase, the Sun’s influence expands and compresses magnetospheres, which serve as protective bubbles of planets with magnetic cores and magnetic fields, including Earth. These protective bubbles are important for shielding planets from the jets of plasma that stream out from the Sun in the solar wind.
Over the centuries that people have been studying solar activity, the quietest times were a three-decade stretch from 1645 to 1715 and a four-decade stretch from 1790 to 1830. “We don’t really know why the Sun went through a 40-year minimum starting in 1790,” Jasinski said. “The longer-term trends are a lot less predictable and are something we don’t completely understand yet.”
In the two-and-a-half decades leading up to 2008, sunspots and the solar wind decreased so much that researchers expected the “deep solar minimum” of 2008 to mark the start of a new historic low-activity time in the Sun’s recent history.
“But then the trend of declining solar wind ended, and since then plasma and magnetic field parameters have steadily been increasing,” said Jasinski, who led the analysis of heliospheric data publicly available in a platform called OMNIWeb Plus, run by NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The data Jasinski and colleagues mined for the study came from a broad collection of NASA missions. Two primary sources — ACE (Advanced Composition Explorer) and the Wind mission — launched in the 1990s and have been providing data on solar activity like plasma and energetic particles flowing from the Sun toward Earth. The spacecraft belong to a fleet of NASA Heliophysics Division missions designed to study the Sun’s influence on space, Earth, and other planets.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
What Would It Take to Say We Found Life?
We call this the podium test. What would it take for you personally to confidently stand up in front of an international audience and make that claim? When you put it in that way, I think for a lot of scientists, the bar is really high.
So of course, there would be obvious things, you know, a very clear signature of technology or a skeleton or something like that. But we think that a lot of the evidence that we might encounter first will be much more subtle. For example, chemical signs of life that have to be detected above a background of abiotic chemistry. And really, what we see might depend a lot on where we look.
On Mars, for example, the long history of exploration there gives us a lot of context for what we might find. But we’re potentially talking about samples that are billions of years old in those cases, and on Earth, those kinds of samples, the evidence of life is often degraded and difficult to detect.
On the ocean worlds of our outer solar system, so places like Jupiter’s moon Europa and Saturn’s moon Enceladus, there’s the tantalizing possibility of extant life, meaning life that’s still alive. But potentially we’re talking about exceedingly small amounts of samples that would have to be analyzed with a relatively limited amount of instrumentation that can be carried from Earth billions of miles away.
And then for exoplanets, these are planets beyond our own solar system. Really, what we’re looking for there are very large magnitude signs of life that can be detectable through a telescope from many light-years away. So changes like the oxygenation of Earth’s atmosphere or changes in surface color.
So any one of those things, if they rose to the suspicion of being evidence of life, would be really heavily scrutinized in a very sort of specific and custom way to that particular observation. But I think there are also some general principles that we can follow. And the first is just: Are we sure we’re seeing what we think we’re seeing? Many of these environments are not very well known to us, and so we need to convince ourselves that we’re actually seeing a clear signal that represents what we think it represents.
Carl Sagan once said, “Life is the hypothesis of last resort,” meaning that we ought to work hard for such a claim to rule out alternative possibilities. So what are those possibilities? One is contamination. The spacecraft and the instruments that we use to look for evidence of life are built in an environment, Earth, that is full of life. And so we need to convince ourselves that what we’re seeing is not evidence of our own life, but evidence of indigenous life.
If that’s the case, we should ask, should life of the type we’re seeing live there? And finally, we need to ask, is there any other way than life to make that thing, any of the possible abiotic processes that we know and even the ones that we don’t know? And as you can imagine, that will be quite a challenge.
Once we have a piece of evidence in hand that we really do think represents evidence of life, now we can begin to develop hypotheses. For example, do we have separate independent lines of evidence that corroborate what we’ve seen and increase our confidence of life?
Ultimately, all of this has to be looked at hard by the entire scientific community, and in that sense, I think the really operative word in our question is we. What does it take to say we found evidence of life? Because really, the answer, I think, depends on the full scientific community scrutinizing and skepticizing this observation to finally say that we scientists, we as a community and we as humanity found life.

Three U.S. military veterans, two from the Air Force and one from the Navy, took the stand Tuesday during the third congressional hearing on Unidentified Anomalous Phenomena (UAPs), the government’s sanitized new term for UFOs.
The most shocking moment came when Congressman Eric Burlison of Missouri unveiled never before seen military footage: a U.S. drone firing a hellfire missile at a mysterious object off the coast of Yemen on October 30, 2024.
The grainy black and white video shows the 100 pound precision weapon streaking toward the target, only to ricochet off harmlessly as the object shot away at impossible speed. Just as baffling, three smaller spheres hovered in formation around the craft, undisturbed by the impact.
Reactions were mixed. Skeptics immediately dismissed the video, claiming it could be nothing more than a misidentified balloon, its apparent speed exaggerated by the drone’s telephoto lens. Others suggested the missile was part of a weapons test rather than a failed strike on something otherworldly.
But the testimony didn’t stop with the video. Two veterans alleged the government has been actively silencing witnesses, threatening those who came forward, and even blacklisting service members who refused to stay quiet. Dylan Borland, a former Air Force geospatial intelligence specialist, testified that multiple agencies conspired to destroy his career blocking jobs, forging documents, and tampering with his security clearance.
For some, this hearing represented a breakthrough in UFO transparency. For others, it was little more than political theater. As one observer put it: it looks like it is just another carefully staged distraction, the UFO spectacle might just be a smokescreen for something deeper.

The first video, beginning around the 1:02 mark, was captured on a dash cam while driving eastbound on a four-lane freeway. Suddenly, a large triangular craft entered the frame, flying approximately 300 to 400 feet above the road.
Although the exact location remains unknown, the sighting is remarkable for its level of visible detail:
A blinking light with two dull orange lights in the center. A large circular feature on the underside, possibly an energy source. A distinctly aerodynamic triangular design. What appears to be an energy field or interference surrounding the craft. An estimated width of 75 to 100 feet, with no audible sound, suggesting non-conventional technology.
When viewed in slow motion, the footage stands out as one of the most striking nighttime captures to date, raising the question: is this a black-budget military project, or evidence of something extraterrestrial? Interestingly, the triangular craft bears a strong resemblance to the rumored TR-3B black manta, an alleged anti-gravity alien reproduction vehicle.
Additional almost similar sightings in Texas and Florida.
Austin, Texas: A dark craft hovering silently in the night sky, completely stationary throughout the entire recording. Sarasota, Florida: Three energy sources forming a triangular pattern while hovering in the night sky. It looks like it could be one of those triangle crafts.
Today, many aerial craft, whether human-made or not, are observed using technologies that remain beyond our current understanding.

The weight of the gods was crushing, their toil beyond endurance. Let the burden pass to humankind! So speak the oldest verses carved into clay, a fragment from the Atrahasis tale of Mesopotamia. Yet what if these divine figures were not simply legends? What if the stories hint at something far older and stranger than we have allowed ourselves to believe? The name Anunnaki comes from the etched symbols of Sumerian records, their lines recounting the deeds of deities who shaped the world and watched over the Earth.
From the cradle of ancient Mesopotamia comes a story older than any empire, etched into clay tablets and whispered through time: the tale of the Anunnaki. Were they gods, symbols, or something far stranger visitors from beyond the stars who shaped human civilization? The myths of Sumer speak of creation, rebellion, giants, and a great flood. But when paired with the ancient astronaut theory, these legends take on a new dimension, one that could rewrite human history.
Who were the Anunnaki? In the ancient Sumerian texts of Mesopotamia, they are described as the offspring of An, the sky god, and Ki, the earth goddess. Their names appear across the Atrahasis epic, the Enuma Elish, the Epic of Gilgamesh, and the Sumerian King List, etched into clay tablets more than 4,000 years ago.
To mainstream historians, the Anunnaki are mythological gods. Yet in the ancient astronaut theory, they were real beings, extraterrestrial visitors who shaped early civilization.
Author Zecharia Sitchin popularized the idea that the Anunnaki came from Nibiru, a hidden “twelfth planet” on a long, elliptical orbit. According to his interpretation of Sumerian records, the Anunnaki faced an environmental crisis. Their planet’s atmosphere was failing, and the solution they sought was gold, which could be ground into particles and suspended as a shield.
This quest for survival brought them to Earth more than 400,000 years ago. They mined resources, altered life, and may even have engineered humanity itself.
The tablets describe how the lesser gods, the Igigi, were forced into back-breaking labor until they rebelled. To replace them, the Anunnaki created humans.
In myth, mankind was formed from clay mixed with divine blood. In Sitchin’s interpretation, this was genetic engineering: the fusion of Anunnaki DNA with Homo erectus. The first prototype was Adamu, a name that echoes the biblical Adam.
The Sumerian “Edin,” later mirrored in the Hebrew Eden, may not have been a paradise garden but an Anunnaki laboratory outpost.
Two Anunnaki brothers shaped humanity’s destiny: Enki – the god of wisdom and waters, often seen as humanity’s ally, granting knowledge. Enlil – stern and authoritarian, seeking control and fearing that humans might grow too powerful. Their rivalry runs through Mesopotamian myth, influencing stories of divine punishment, survival, and human struggle.
Over time, some Anunnaki defied the rules and took human women as partners. Their offspring were the Nephilim, giants and “mighty men of renown.” The Book of Enoch calls their fathers the Watchers, led by Shemyaza.
According to the stories, these hybrids grew violent, corrupted the world, and became uncontrollable. The solution was drastic: a great flood to wipe the Earth clean.
The Atrahasis epic, the story of Utnapishtim in the Epic of Gilgamesh, and the biblical Noah all describe the same event: a chosen man warned by a god, a vessel built to preserve life, animals carried aboard, and birds released to find land. Humanity survived, but weaker, with shorter lifespans, and forever changed.
Supporters of the ancient astronaut theory believe the Anunnaki left traces in stone:
Mesopotamian ziggurats – described as “bonds between heaven and earth,” possibly landing platforms.
The Great Pyramid of Giza – aligned to true north, massive in scale, theorized as a power plant or beacon rather than a tomb.
Megalithic monuments worldwide – stone circles, cyclopean walls, and sacred sites possibly linked to Anunnaki influence.
The Sumerian King List also suggests a divine legacy, describing rulers with lifespans of thousands of years, perhaps evidence of semi-divine hybrids.
Mainstream archaeology sees the Anunnaki as symbolic deities, metaphors for cosmic order and human struggle. But in alternative history, they were real beings, extraterrestrial visitors from Nibiru, who shaped civilization, taught astronomy, metallurgy, agriculture, and law, and left their mark in myths and monuments that endure to this day.
Explore the mystery of the Anunnaki—Sumerian gods, Nibiru, genetic engineering, Nephilim, the Great Flood, and the ancient astronaut theory in the video below.
