With less than 48 hours until the total solar eclipse crosses Greenland, Iceland, and Spain on August 12, local infrastructure across Southern Europe is reaching a breaking point. Hotel rates in the path of totality have quadrupled, while regional authorities in Spain prepare emergency traffic plans to manage millions of incoming eclipse tourists. While scientists are seizing this rare two-minute window of totality to gather solar corona data, the commercial frenzy highlights how event-driven tourism routinely overwhelms regional economies. Chasing rare celestial phenomena has turned into a volatile hospitality market, where public infrastructure bears the burden of short-term economic spikes.

On November 27 and 28, a series of powerful solar flares swept across the Sun’s surface, creating this coronal hole. This phenomenon is a temporary region of relatively cool, less dense plasma in the solar corona where the Sun's magnetic field extends into interplanetary space as an open field. The open magnetic field of a coronal hole allows solar wind to escape into space at a much quicker rate, leading to increased chances of geomagnetic storms upon colliding with Earth’s magnetosphere.

The Earth's magnetic field protects us not only from solar flares but also from cosmic radiation. When the Sun enters a Grand Solar Minimum, its magnetic field weakens for a long period. This lets more cosmic radiation into the Solar System, and this directly impacts the climate on Earth and increases volcanic activity. The last Little Ice Age occurred during a Grand Solar Minimum. But the coming Grand Solar Minimum is going to hit harder because the Earth's magnetic field is at least 30% weaker and, with the ongoing geomagnetic excursion, is continuing to weaken. This will let in more cosmic radiation, which will directly cause mutations, pandemics, cooling, crop failures, and even crustal displacement. Since the advent of modern technology, we haven't experienced either a Grand Solar Minimum or a geomagnetic excursion, and we are due for both.

The total lunar eclipse started at 23:28 on Sunday evening and conclude at 04:55 on Monday morning, Beijing time. The totality phase, known as the "red moon," will last from 01:31 to 02:53, with a duration of one hour and 22 minutes. "A lunar eclipse is rare. It occurs when the earth moves right in the middle of the moon and the sun, blocking the sunlight from shining on the moon. The total lunar eclipse this time will last for a relatively long time as it will enter the earth's shadow quite deeply. " said by an expert at Beijing Planetarium. This eclipse can be observed with the naked eye under good weather conditions.

🌒☀️ THE UK’S BIGGEST SOLAR ECLIPSE SINCE 1999 IS ALMOST HERE! ☀️🌒 Good afternoon everyone, On Wednesday 12th August, people across the UK will have the chance to witness the greatest solar eclipse visible from the UK since the famous 1999 eclipse — and we won’t get another eclipse this impressive from the UK until 2081! 🤯 Exactly how much of the Sun disappears behind the Moon — and the time of maximum eclipse — will depend on where you are in the country. Some western areas will get an especially impressive view as the eclipse takes place during the evening and heads towards sunset. 🌅🌒 ⚠️ PLEASE PROTECT YOUR EYES! Never look directly at the Sun, even when most of it is covered by the Moon. Use proper certified solar-eclipse glasses or an indirect viewing method such as a pinhole projector. Ordinary sunglasses are NOT safe. 📲 Please share or forward this to your family and friends so they know there’s something rather special happening in the sky on Wednesday evening! After all, the next comparable UK opportunity is a very long wait… 2081! 😳☀️🌒

A spectacular “Ring of Fire” just blazed across the Antarctic sky today, February 17, 2026 — the first solar eclipse of the year, and a rare annular one that turned the Sun into a blazing celestial halo. In this stunning alignment, the Moon slipped between Earth and the Sun but — because it was near the farther point in its elliptical orbit (close to apogee) — appeared slightly smaller than the Sun's disk. Instead of total darkness, a brilliant ring of sunlight encircled the Moon's dark silhouette, creating that iconic fiery annulus for up to about 2 minutes and 20 seconds at maximum.The path of true annularity carved a narrow corridor roughly 616 km (383 miles) wide and 4,282 km (2,661 miles) long across the icy expanse of Antarctica — one of the most remote and inhospitable places on Earth. Very few humans witnessed the full “Ring of Fire”: perhaps a handful at research stations like Concordia Station, where the peak hit around 19:47 local time (12:13 UTC / 7:13 a.m. EST), with the Sun about 96% obscured.Everywhere else in the vast southern regions, the eclipse appeared as a dramatic partial bite taken from the Sun. Partial phases were visible across:Much of southern Africa (including South Africa, Mozambique, Madagascar) The southern tips of Argentina and Chile Broad swaths of the Southern Ocean, Pacific, Atlantic, and Indian Oceans The event kicked off with the first partial shadows around 09:56 UTC, reached maximum at 12:13 UTC, and wrapped up by 14:27 UTC — a roughly 4.5-hour celestial dance viewed from half a hemisphere away.Astronomy enthusiasts and scientists alike marveled at the precision of orbital mechanics on display: the Moon's apparent size just shy of perfect coverage, the Sun's corona faintly visible around the edges in safe-filtered views, and the eerie dimming of daylight in partial zones.This remote spectacle kicks off what many are calling a golden age of eclipses — with a total solar eclipse coming up on August 12, 2026 (visible from Greenland, Iceland, and northern Spain), followed by more totals and annulars through 2028.A reminder of cosmic rhythm: even in the harshest, loneliest corners of our planet, the universe puts on a show of breathtaking beauty and perfect timing.(Sources: NASA eclipse resources, Wikipedia Solar Eclipse of February 17, 2026, EarthSky, and related astronomical reports.)

🚨 NASA’S PARKER SOLAR PROBE IS NOW FLYING THROUGH THE SUN. Not orbiting near it. Not observing from a safe distance. It’s actually moving through the Sun’s outer atmosphere the corona at 430,000 mph. Fast enough to cross the entire continental United States in about 20 seconds. Yet the front of the spacecraft is glowing at 2,500°F (hotter than molten lava) while the delicate instruments behind its heat shield remain near room temperature. Why this matters: For decades one of the biggest unsolved mysteries in physics has been the Sun’s corona. It reaches temperatures of millions of degrees while the visible surface below it is far cooler. That’s like standing farther from a campfire and suddenly feeling hotter. Parker is now flying directly through the region where that mystery is born. It’s already revealing: • Strange magnetic “switchbacks” • Unexpected solar wind structures • Jagged boundaries where the Sun’s atmosphere escapes into space • Plasma behavior never seen before in human history The deeper implication is staggering: Everything on Earth depends on the Sun our weather, climate, satellites, power grids, even life itself. Yet we’ve spent most of human history studying it from 93 million miles away. For the first time… we’re touching the atmosphere of a star. What do you think Parker will discover next something expected… or something that forces us to rewrite solar physics entirely? Follow for more frontier physics and cosmic discoveries.

Space objects such as meteoroids and asteroids move across the solar system and can collide with both Earth and the Moon. However, the Moon shows far more visible impact marks on its surface. One main reason is that Earth has a thick atmosphere that protects the planet. When many meteoroids enter Earth’s atmosphere, they burn up due to friction before they can reach the ground. This process creates the bright streaks of light we call shooting stars. The Moon, however, has almost no atmosphere, so incoming space rocks are not slowed down or burned up. They travel directly to the lunar surface and strike it at very high speed. Each collision creates an impact crater, throwing dust and rocks outward from the impact point. Over billions of years, thousands of these impacts have covered the Moon with craters. Unlike Earth, the Moon also has no wind, water, or weather to erase these craters, so they remain visible for millions or even billions of years. This is why the Moon looks heavily cratered when we observe it from Earth through telescopes.

🚨 CHINA IS RACING TO BUILD A SPACE SOLAR POWER PLANT THAT COULD BEAM ELECTRICITY FROM ORBIT TO EARTH. Scientists at Xidian University have successfully tested a ground-based system that can wirelessly transmit kilowatt-level power over 100 meters using microwaves. Their ultimate goal is far more ambitious: placing large solar power stations in geostationary orbit (36,000 km up), where sunlight is available 24/7 with no weather or atmosphere blocking it. The project, called Zhuri (“chasing the sun”), uses mirrors to concentrate sunlight onto solar panels, converts the electricity into microwaves, and beams it down to a receiving antenna (rectenna) on Earth. Why this matters: • In space, solar energy is up to 6 times more efficient than on Earth because there’s no night, clouds, or atmospheric filtering • A single large space solar station could theoretically generate gigawatts of continuous clean power enough for millions of homes • The team has already proven the system can beam power to multiple moving targets at once • China is now among the world leaders in this technology, alongside the US and Japan The deeper implication: Space-based solar power has been a dream for decades because it could provide truly baseload renewable energy. While the technical and financial challenges are enormous (building massive structures in orbit, precise microwave beaming, and safety), steady progress like this brings the concept closer to reality. If successful, it could fundamentally change how humanity generates and distributes energy moving power collection off the planet entirely. Near-term applications could include wirelessly charging satellites or powering future lunar bases. Do you think space-based solar power will become a major energy source in the coming decades, or will it stay too expensive and complex?

🚨 SOLAR FLARES: HOTTER, MEANER, SCARIER Scientists just discovered the Sun’s tantrums are way nastier than we thought. New research says ions inside solar flares can hit 60 million degrees - about 6.5x hotter than earlier estimates. The culprit? Magnetic reconnection - cosmic wires crossing in the Sun’s atmosphere, supercharging particles to hellfire levels. Solar flares aren’t just pretty space fireworks. They hurl radiation at Earth in minutes, frying satellites, threatening astronauts, and messing with the planet’s upper atmosphere. Think GPS glitches, blackouts, and potential chaos for a world glued to digital infrastructure. Until now, scientists assumed flare particles heated evenly. Turns out, ions are cooking at extreme temps that make fusion reactors look like spa baths. Our nearest star is more violent, less predictable, and possibly more dangerous than the textbooks said.

You’re looking at thousands of studs that have been jammed into the ground, on what was previously prime farmland, as they continue to build out Cider Solar in Elba and Oakfield, New York. The studs will hold the Chinese-made solar panels that were constructed and shipped with fossil fuels and rare earth minerals. Cider Solar is a massive 500MW industrial complex that will destroy 4,000 acres by the time they’re done. Since commercial solar only generates at 15% of its annual potential in Upstate NY (actually closer to 10% in Western NY), this 500MW complex will only generate 75MW of power when it’s all said and done. Thousands of acres gone. Soil compacted. Runoff reported. Chemicals sprayed to suppress vegetation. Animals displaced in every direction. And the history and culture of these towns destroyed forever. All for our governor, greedy politicians, and subsidies for foreign corporations. Video submitted by Jennifer Suzanne

🚨 PARKER SOLAR PROBE JUST FOUND HIGH-ENERGY PARTICLES NEAR THE SUN THAT NO MODEL PREDICTED AND WE DON’T KNOW HOW THEY GOT SO ENERGETIC. During its close passes through the solar corona, NASA’s Parker Solar Probe detected protons accelerated to energies around 400 keV roughly 1,000 times higher than current models of magnetic reconnection at the heliospheric current sheet could explain. The particles appear to be trapped and energized inside magnetic islands that form and merge during reconnection events at the current sheet (the vast surface where the Sun’s magnetic field flips polarity). This mechanism was not expected to produce such high energies so close to the Sun. Why this matters: • It reveals a previously unknown or underestimated source of energetic particles right in the solar corona • Existing models of solar energetic particles have focused mainly on shocks from coronal mass ejections — this suggests reconnection can also be a powerful accelerator • The same process may be contributing more to coronal heating than previously calculated • It has implications for space weather forecasting, since these particles can affect spacecraft and astronauts The deeper implication: Parker is showing us that the physics of the near-Sun environment is more energetic and complex than our models assumed. Magnetic reconnection long known as an important process appears capable of accelerating particles to surprisingly high energies through the merging of magnetic islands. This doesn’t just tweak our understanding of the Sun; it may force revisions in how we model particle acceleration across many astrophysical environments. We’re still in the early stages of understanding what Parker is revealing, but it’s already clear that the corona is more violent and dynamic than we thought. How do you think this discovery might change our models of space weather or solar physics in the coming years? Follow for more updates from Parker Solar Probe and the evolving picture of our Sun.

Think Solar panels are "Green"? think again. Making solar panels requires toxic chemicals, huge amounts of energy and water, and creates toxic waste. The common types (mono- and poly-crystalline panels) need extremely high heat at every stage of production. For example, temperatures of 2,700°F to 3,600°F are required just to turn sand-like silicon dioxide into usable silicon. Up to half of that silicon is then wasted when the thin wafers are cut. For every 1 megawatt of solar panels produced: About 1.4 tons of toxic chemicals are used (including hydrochloric acid, sodium hydroxide, sulfuric acid, nitric acid, and hydrogen fluoride). Nearly 2,900 tons of water are needed. 8.6 tons of pollution are released—most of it from powerful greenhouse gases (SF₆, NF₃, and C₂F₆) that trap heat thousands of times more effectively than carbon dioxide. Other dangerous waste includes toxic gases like trichlorosilane and silicon tetrachloride, plus harmful dust from the cutting process. The thinner “amorphous” or thin-film solar panels are made with cadmium, a chemical known to cause cancer and damage DNA. By the end of 2016 the world already had about 250,000 tonnes of discarded solar panels. That was just 0.5 % of all electronic waste produced that year. The International Renewable Energy Agency estimates that by 2050 we could be throwing away 6 million tonnes of solar panels every single year, adding up to a total of 78 million tonnes. At that point dead solar panels could make up 10 % of all electronic waste, and the total amount of worn-out panels could be larger than all the electronic waste the world produced in 2018. Recycling is often presented as the easy fix, but it isn’t. It still uses large amounts of energy, water and other resources, and workers have to handle toxic materials that eventually need to be disposed of. Right now only two commercial recycling methods exist for solar panels, and there are just a handful of facilities that can do the job anywhere in the world. #GreenEnergy

Since everyone lived it's safe to say this was probably the most fun this pilot and sensor officer ever had... 👀😎 Great skill to make it out safe for sure. “Today, a mechanical issue with one of NASA’s WB-57s resulted in a gear-up landing at Ellington Field. Response to the incident is ongoing, and all crew are safe at this time. As with any incident, a thorough investigation will be conducted by NASA into the cause. NASA will transparently update the public as we gather more information.” -NASA spokesman #flying #WB57 #NASA #houston #crashland #pilot

We continue to analyze the technical details of the war with Iran, and we would like to note the Iranian novelty - subsonic barraging anti-aircraft missiles Missile 358, equipped with compact turbojet engines. To some extent unexpectedly, they showed good effectiveness against Israeli reconnaissance and strike UAVs Hermes-900. The key role is played by the thermal homing head: it is able to reliably detect and track a wide range of heat-contrasting targets, including UAVs with various flight profiles. An additional advantage is the command and telemetry channel, which ensures data transmission and allows for radio correction of the trajectory. This is especially important in situations when the target attempts to disrupt the capture with infrared decoys or other means of counteraction. According to the stated parameters, the range of application of Missile 358 reaches about 100 km. At the same time, the maximum interception altitude is about 8.5 km, and the speed is up to 700 km/h, which expands the capabilities of the complex in covering objects and intercepting medium-altitude UAVs. Of course, this is a niche tool, and compared to solid-fuel missiles, the turbojet engine provides exponentially higher flight energy. This allows to dramatically increase the range at low speed, and the mass of the main units of the ammunition, its warhead and control system. On the other hand, this is a solution of necessity, because classic anti-aircraft missiles perfectly hit such high-altitude and slow-moving targets. But for such ammunition, no radar, complex and expensive beam installations are required, which greatly improves its survivability under constant air strikes. And in its niche of targets, there are enough of them, as such UAVs of Israel and the USA are the basis of UCAV, and are constantly over the territory of Iran. So with the 358th ammunition, you can score quite a lot of frags, and significantly complicate air strikes on Iran for the Epstein coalition. Russian Engineer -

Contrail lesson! 1. “Chemtrails” don’t exist. Just to get that out of the way. 2. Observe the satellite loop and Skew-T chart. In the IR satellite loop you can see yesterday, the West Coast had a decent short wave ridge suppressing moisture over California and Nevada. Today, you can see moisture from a low pressure over the Pacific spilling over the ridge that is now moving east of California. This is upper level moisture ADVECTING into the area. This upper level moisture is mainly above the 500mb level, or 20,000ft. 3. Now observe the Skew-T chart. Particularly clue into the 300mb level. This is a perfect example of what I talk about all the time, and why it’s important to pay attention to the 300mb level. This moisture layer is advecting particularly at the 300mb level, and synoptic scale cirrus development, and advection, typically occurs at 300mb. This is key because aircraft are flying at and above the 300mb level. 4. So, lastly, observe the pictures that I took of the sky over northern Nevada at the time of this post. You can see the layer of cirrus as well as contrails persisting in that moisture layer, exactly as depicted in the satellite shot AND confirmed by the Skew-T chart. Keep in mind that temperatures at this level of the atmosphere are typically -20 to -50°C. In this case, you can see that the temperature at 300mb is -40°C and relative humidities at this level are far different than what you experience at the surface. Any decrease in the gap between temperature and dewpoint at this level can significantly increase the relative humidity. This is why it’s referred to as “relative”because it’s far different than temperatures and dew points at the surface. So, to bring it all together, aircraft flying at these altitudes, which most commercial and military aircraft do, injecting warm, moist air from the engines rapidly into the super cooled environment, not only instantly form contrails, but when relative humidities are as depicted in this example, will enable contrails to persist for hours at a time supported by the moisture existing in that layer. This is what causes persistent contrails. These ARE NOT “chemtrails” and because they persist, does not, and will not ever, make them “chemtrails.” Now that you all needed your government to tell you that climate change was a hoax and I’ve been telling you for years that the “Geoengineering” and “chemtrail” nonsense are propaganda directly related to the climate change hoax, hopefully you can take some time to learn the basics of the atmosphere and understand what I’m showing you here, and how it works, so you’re not fooled by climate propaganda going forward. Thank you for your attention to this matter. 💪🏼🇺🇸

USAAF 14th PRS Spitfire PR Mk XI gunned down at point blank range likely by a Luftwaffe Me 262 jet fighter in 1944 The incident pictured most likely involved Spitfire PR Mk XI PL782 flown by 2nd Lt Robert B Hilborn. The aircraft was intercepted over Lechfeld by Leutnant Alfred Schreiber of Erprobungskommando 262 in Me262 A-1a WerkNr. 110372 "White 3". This latter unit was the first to deploy the Messerschmitt jet and would later form Kommando Nowotny. Hilborn managed to bail out of his stricken aircraft and was taken prisoner. The USAAF insignia on the top of the port wing is clearly visible as the aircraft banks away and both the severe vibration on firing and size of the cannon shell impacts suggest 30mm gunfire consistent with the Me 262's MK 108 battery in the nose, and the jet aircraft would also have been able to comfortably keep up with the fast unarmed photoreconnaissance Spitfire variant at altitude. The 3cm Minengeschoss high-capacity shells were formidable projectiles each containing over 70 grams of high explosive and were designed to detonate within six or so inches of having penetrated the aircraft skin, destroying the aircraft structure in the process and rendering the aircraft unflyable after only a few hits. The amount of debris flying off the Spitfire after only three visible detonations is testament to the devastating effect of such fire. The US 14th Photographic Reconnaissance Squadron began to train with British-made Supermarine Spitfire Mk V fighters in July 1943 before equipping with the photographic reconnaissance PR Mk XI variant later that year. The squadron flew combat reconnaissance missions in the European Theater of Operations from August 12th 1943 until April 25th 1945. The squadron's Spitfires flew the majority of the target photography missions, including the first Spitfire reconnaissance mission over Berlin in March 1944, while the other squadrons of the 7th Photographic Group (Reconnaissance) equipped with F-5 Lightnings concentrated on photographic mapping. Deep penetration missions included reconnaissance of oil refineries to determine when repairs had been performed that could justify returning them to Eighth Air Force's target list. The Squadron earned a Distinguished Unit Citation for reconnaissance missions flown over France between May 31st 1944 and the end of June. The squadron flew over 300 successful sorties to support Operation Overlord, the invasion of Normandy. It flew missions over the Netherlands to support Operation Market Garden in October 1944 and conducted damage assessment of Germany until July 23rd 1945. In late 1944, the Spitfires, flying solo missions and relying only on speed and altitude for defense, began to prove vulnerable to the jet powered Messerschmitt Me 262 fighters entering service with the Luftwaffe. A squadron aircraft lost on September 5th 1944 was probably the first Army Air Forces loss to a German jet fighter. Erprobungskommando 262 had been formed in April 1944 at Lechfeld just south of Augsburg, as a test unit (Jäger Erprobungskommando Thierfelder, commanded by Hauptmann Werner Thierfelder) to introduce the Me 262 into service and train a corps of pilots to fly it. This was not Leutnant Schreiber's first go at an Allied reconnaissance plane, while flying over Munich on July 26th he encountered a Mosquito PR Mark XVI of No. 540 Squadron RAF piloted by Fl. Lt. A.E. Wall. Schreiber attempted to shoot down the unarmed Mosquito, though Wall evaded Schreiber's three attack runs and was able land safely at Fermo in Italy after what was the first air to air interception by a jet fighter in history.

BREAKING – A significant Earth-directed solar flare and associated coronal mass ejection (CME) just occurred on Friday evening. There is an increasing chance of geomagnetic storms and the potential for a display of the aurora borealis (northern lights) sometime Sunday night into Monday. A "solar flare" is a flash of light and radiation flickering into space. They emanate from sunspots – bruise-like discolorations on the surface of the sun that throb and pulsate with energy. That just occurred associated with sunspot #4100. The flare was a magnitude M8.2; M is one step below X, the highest category. An M8.2 is very close to X-class status. It was followed by a "full halo CME", or coronal mass ejection. That's an explosion of magnetism and solar material that surfs a shockwave through space. We call it a "full halo" because – when it's pointed directly at Earth – it looks like a halo. When CMEs, or coronal mass ejections, arrive at Earth, the electromagnetic energy is absorbed and dissipated by Earth's magnetic field. That energy is transformed into visible light – the aurora. I'll have updates once more information becomes available.
