      Since November 2024, strange blinking lights have been reported worldwide, an unexplained phenomenon that’s left many puzzled. MrMBB333 believes he may have found a connection. 

      Also known as electrical pollution, dirty electricity refers to high-frequency voltage spikes that ride along standard power lines. These rogue signals, forms of electromagnetic interference (EMI), can spread through our infrastructure, causing devices to glitch or behave unpredictably. 
      If this interference is appearing globally, the source might be something massive, possibly deep within Earth’s core. Rogue frequencies from the core could travel up and interact with power grids, solar systems, and transmission lines, triggering widespread anomalies. 
      Supporting this idea is a discovery from NASA’s ANITA project in Antarctica. While searching for cosmic neutrinos, scientists instead detected impossible radio signals rising from deep within Earth, signals that defy current physics.  
      According to current science, these waves should have been absorbed by the Earth’s crust long before reaching the detectors. But they weren’t. 
      When researchers checked their findings against other experiments, nothing lined up. This means they didn’t detect neutrinos, but something entirely unknown. Could this be a new kind of particle? A glitch in reality? Or something even stranger? 
      Although it is not known whether the strange radio signals detected deep beneath the Antarctic ice are related to the rogue signals believed to originate from Earth's core, MrMBB333 suggests there could be a connection. He proposes that similar forms of electromagnetic interference (EMI) might be disrupting global electronics and even contributing to the mysterious blinking light phenomenon. 
      Another possible factor at play is that the magnetic field is weakening as well as Solar Cycle 25 — the current 11-year cycle of solar activity marked by the Sun’s magnetic field reversal and increasing sunspot activity. This cycle began in December 2019 and is expected to reach its peak in 2025. 
      Therefore, could this solar phenomenon be interfering with the rogue electromagnetic signals from the Earth’s core are behind the strange blinking lights observed around the world? 
      If that’s the case, although I don’t recall the blinking light phenomenon ever appearing this intensely before, then the strange lights may begin to fade as Solar Cycle 25 winds down. Still, that doesn’t explain the origin of the mysterious radio signals rising from deep beneath Antarctica’s ice.

      A mysterious object within our own galaxy is emitting a bizarre pulsing signal directed at Earth, one that scientists say is unlike anything ever recorded, and they haven’t ruled out an alien origin. 
      NASA astrophysicist Dr. Richard Stanton, who led the research team, described the signal as “strange” and said its properties defy all known astrophysical explanations. “In more than 1,500 hours of observations, we’ve never seen a pulse like this,” 

      Stanton noted. The signal originates from a sun-like star approximately 100 light-years away in the constellation Ursa Major (the Great Bear). It was first detected as a flash of light that abruptly brightened, dimmed, and then brightened again, an unusual pattern that immediately drew attention.
      Even more puzzling, the pulse repeated exactly four seconds later, matching the first in every detail.
      According to Stanton’s findings, published in Acta Astronautica, the signal also triggered bizarre activity in the host star, causing it to partially vanish in just a tenth of a second, a phenomenon with no clear scientific explanation. 
      It's noteworthy that this object was specifically targeting Earth with its signal, not just broadcasting randomly into space, but directing its transmission toward our planet. 
      Whatever the intention behind it, that alone is intriguing. Even more interesting is that NASA publicly acknowledged this discovery. While NASA’s statements aren't always fully transparent, could this be a prelude to something bigger, perhaps a forthcoming revelation about the discovery of a Dyson Sphere, or even confirmation of intelligent extraterrestrial life?

      Eclipses, Auroras, and the Spark of Becoming: NASA Inspires Future Scientists
      In the heart of Alaska’s winter, where the night sky stretches endlessly and the aurora dances across the sky in a display of ethereal beauty, nine undergraduate students from across the United States were about to embark on a transformative journey. These students had been active ‘NASA Partner Eclipse Ambassadors’ in their home communities, nine of more than 700 volunteers who shared the science and awe of the 2024 eclipse with hundreds of thousands of people across the country as part of the NASA Science Activation program’s Eclipse Ambassadors project. Now, these nine were chosen to participate in a once-in a lifetime experience as a part of the “Eclipses to Aurora” Winter Field School at the University of Alaska Fairbanks. Organized by the Astronomical Society of the Pacific and NASA’s Aurorasaurus Citizen Science project, supported by NASA, this program offered more than just lectures—it was an immersive experience into the wonders of heliophysics and the profound connections between the Sun and Earth.
      From January 4 to 11, 2025, the students explored the science behind the aurora through seminars on solar and space physics, hands-on experiments, and tours of cutting-edge research facilities like the Poker Flat Research Range. They also gained invaluable insight from Athabaskan elders, who shared local stories and star knowledge passed down through generations. As Feras recalled, “We attended multiple panels on solar and space physics, spoke to local elders on their connection to the auroras, and visited the Poker Flat Research Range to observe the stunning northern lights.”
      For many students, witnessing the aurora was not only a scientific milestone, but a deeply personal and emotional experience. One participant, Andrea, described it vividly: “I looked to the darkest horizon I could find to see my only constant dream fulfilled before my eyes, so slowly dancing and bending to cradle the stars. All I could do, with my hands frozen and tears falling, I began to dream again with my eyes wide open.” Another student, Kalid, reflected on the shared human moment: “Standing there under the vast Alaskan sky… we were all just people, looking up, waiting for something magical. The auroras didn’t care about our majors or our knowledge—they brought us together under the same sky.”
      These moments of wonder were mirrored by a deeper sense of purpose and transformation. “Over the course of the week, I had the incredible opportunity to explore auroras through lectures on solar physics, planetary auroras, and Indigenous star knowledge… and to reflect on these experiences through essays and presentations,” said Sophia. The Winter Field School was more than an academic endeavor—it was a celebration of science, culture, and shared human experience. It fostered not only understanding but unity and awe, reminding everyone involved of the profound interconnectedness of our universe.
      The impact of the program continues to resonate. For many students, that one aurora-lit week in Alaska became a turning point in the focus of their careers. Sophia has since been accepted into graduate school to pursue heliophysics. Vishvi, inspired by the intersection of science and society, will begin a program in medical physics at the University of Pennsylvania this fall. And Christy, moved by her time at the epicenter of aurora research, has applied to the Ph.D. program in Space Physics at the University of Alaska Fairbanks—the very institution that helped spark her journey. Their stories are powerful proof that the Winter Field School didn’t just teach—it awakened purpose, lit new paths, and left footprints on futures still unfolding.

      NASA Observes First Visible-light Auroras at Mars
      On March 15, 2024, near the peak of the current solar cycle, the Sun produced a solar flare and an accompanying coronal mass ejection (CME), a massive explosion of gas and magnetic energy that carries with it large amounts of solar energetic particles. This solar activity led to stunning auroras across the solar system, including at Mars, where NASA’s Perseverance Mars rover made history by detecting them for the first time from the surface of another planet.
      The first visible-light image of green aurora on Mars (left), taken by the Mastcam-Z instrument on NASA’s Perseverance Mars rover. On the right is a comparison image of the night sky of Mars without aurora but featuring the Martian moon Deimos. The moonlit Martian night sky, lit up mostly by Mars’ nearer and larger moon Phobos (outside the frame) has a reddish-brown hue due to the dust in the atmosphere, so when green auroral light is added, the sky takes on a green-yellow tone, as seen in the left image. NASA/JPL-Caltech/ASU/MSSS/SSI “This exciting discovery opens up new possibilities for auroral research and confirms that auroras could be visible to future astronauts on Mars’ surface.” said Elise Knutsen, a postdoctoral researcher at the University of Oslo in Norway and lead author of the Science Advances study, which reported the detection.
      Picking the right aurora
      On Earth, auroras form when solar particles interact with the global magnetic field, funneling them to the poles where they collide with atmospheric gases and emit light. The most common color, green, is caused by excited oxygen atoms emitting light at a wavelength of 557.7 nanometers. For years, scientists have theorized that green light auroras could also exist on Mars but suggested they would be much fainter and harder to capture than the green auroras we see on Earth.
      Due to the Red Planet’s lack of a global magnetic field, Mars has different types of auroras than those we have on Earth. One of these is solar energetic particle (SEP) auroras, which NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission discovered in 2014. These occur when super-energetic particles from the Sun hit the Martian atmosphere, causing a reaction that makes the atmosphere glow across the whole night sky.
      While MAVEN had observed SEP auroras in ultraviolet light from orbit, this phenomenon had never been observed in visible light from the ground. Since SEPs typically occur during solar storms, which increase during solar maximum, Knutsen and her team set their sights on capturing visible images and spectra of SEP aurora from Mars’ surface at the peak of the Sun’s current solar cycle.
      Coordinating the picture-perfect moment
      Through modeling, Knutsen and her team determined the optimal angle for the Perseverance rover’s SuperCam spectrometer and Mastcam-Z camera to successfully observe the SEP aurora in visible light. With this observation strategy in place, it all came down to the timing and understanding of CMEs.
      “The trick was to pick a good CME, one that would accelerate and inject many charged particles into Mars’ atmosphere,” said Knutsen.
      That is where the teams at NASA’s Moon to Mars (M2M) Space Weather Analysis Office and the Community Coordinated Modeling Center (CCMC), both located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, came in. The M2M team provides real-time analysis of solar eruptions to the CCMC for initiating simulations of CMEs to determine if they might impact current NASA missions. When the simulations suggest potential impacts, the team sends out an alert.
      At the University of California, Berkeley, space physicist Christina Lee received an alert from the M2M office about the March 15, 2024, CME. Lee, a member of the MAVEN mission team who serves as the space weather lead, determined there was a notable solar storm heading toward the Red Planet,which could arrive in a few days. She immediately issued the Mars Space Weather Alert Notification to currently operating Mars missions.
      “This allows the science teams of Perseverance and MAVEN to anticipate impacts of interplanetary CMEs and the associated SEPs,” said Lee.
      “When we saw the strength of this one,” Knutsen said, “we estimated it could trigger aurora bright enough for our instruments to detect.”
      A few days later, the CME impacted Mars, providing a lightshow for the rover to capture, showing the aurora to be nearly uniform across the sky at an emission wavelength of exactly 557.7 nm. To confirm the presence of SEPs during the aurora observation, the team looked to MAVEN’s SEP instrument, which was additionally corroborated by data from ESA’s (European Space Agency) Mars Express mission. Data from both missions confirmed that the rover team had managed to successfully catch a glimpse of the phenomenon in the very narrow time window available.
      “This was a fantastic example of cross-mission coordination. We all worked together quickly to facilitate this observation and are thrilled to have finally gotten a sneak peek of what astronauts will be able to see there some day,” said Shannon Curry, MAVEN principal investigator and research scientist at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder (CU Boulder).
      The future of aurora on Mars
      By coordinating the Perseverance observations with measurements from MAVEN’s SEP instrument, the teams could help each other determine that the observed 557.7 nm emission came from solar energetic particles. Since this is the same emission line as the green aurora on Earth, it is likely that future Martian astronauts would be able to see this type of aurora.
      “Perseverance’s observations of the visible-light aurora confirm a new way to study these phenomena that’s complementary to what we can observe with our Mars orbiters,” said Katie Stack Morgan, acting project scientist for Perseverance at NASA’s Jet Propulsion Laboratory in Southern California. “A better understanding of auroras and the conditions around Mars that lead to their formation are especially important as we prepare to send human explorers there safely.”
      On September 21, 2014, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft entered orbit around Mars. The mission has produced a wealth of data about how Mars’ atmosphere responds to the Sun and solar wind NASA/JPL-Caltech More About Perseverance and MAVEN

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s Curiosity Mars rover sees its tracks receding into the distance at a site nicknamed “Ubajara” on April 30, 2023. This site is where Curiosity made the discovery of siderite, a mineral that may help explain the fate of the planet’s thicker ancient atmosphere.Credit: NASA/JPL-Caltech/MSSS New findings from NASA’s Curiosity Mars rover could provide an answer to the mystery of what happened to the planet’s ancient atmosphere and how Mars has evolved over time.
      Researchers have long believed that Mars once had a thick, carbon dioxide-rich atmosphere and liquid water on the planet’s surface. That carbon dioxide and water should have reacted with Martian rocks to create carbonate minerals. Until now, though, rover missions and near-infrared spectroscopy analysis from Mars-orbiting satellites haven’t found the amounts of carbonate on the planet’s surface predicted by this theory.
      Reported in an April paper in Science, data from three of Curiosity’s drill sites revealed the presence of siderite, an iron carbonate mineral, within the sulfate-rich rocky layers of Mount Sharp in Mars’ Gale Crater.
      “The discovery of abundant siderite in Gale Crater represents both a surprising and important breakthrough in our understanding of the geologic and atmospheric evolution of Mars,” said Benjamin Tutolo, associate professor at the University of Calgary, Canada, and lead author of the paper.
      To study the Red Planet’s chemical and mineral makeup, Curiosity drills three to four centimeters down into the subsurface, then drops the powdered rock samples into its CheMin instrument. The instrument, led by NASA’s Ames Research Center in California’s Silicon Valley, uses X-ray diffraction to analyze rocks and soil. CheMin’s data was processed and analyzed by scientists at the Astromaterials Research and Exploration Science (ARES) Division at NASA’s Johnson Space Center in Houston.
      “Drilling through the layered Martian surface is like going through a history book,” said Thomas Bristow, research scientist at NASA Ames and coauthor of the paper. “Just a few centimeters down gives us a good idea of the minerals that formed at or close to the surface around 3.5 billion years ago.”
      The discovery of this carbonate mineral in rocks beneath the surface suggests that carbonate may be masked by other minerals in near-infrared satellite analysis. If other sulfate-rich layers across Mars also contain carbonates, the amount of stored carbon dioxide would be a fraction of that needed in the ancient atmosphere to create conditions warm enough to support liquid water. The rest could be hidden in other deposits or have been lost to space over time.
      In the future, missions or analyses of other sulfate-rich areas on Mars could confirm these findings and help us better understand the planet’s early history and how it transformed as its atmosphere was lost.
      Curiosity, part of NASA’s Mars Exploration Program (MEP) portfolio, was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington.
