Sun vs. comet! ☀️⚔️☄️ In October 2025, comet Lemmon (C/2025 A6) was passing by the Sun when our star launched a counterattack — a blast of solar particles that ripped the comet’s tail in half! NASA’s PUNCH mission (Polarimeter to Unify the Corona and Heliosphere) captured the action from Earth orbit, imaging comet Lemmon every 4 to 8 minutes over three months. PUNCH’s data make up one of the longest and most detailed records ever captured of a comet interacting with the Sun. Check it out! 👀 NASA’s Illuminate: Out-of-this-world images shining light on our Sun and solar system. #NASAsIlluminate #NASA #sun #space #science

It’s #SunDay! Here’s your space weather report for the week of Sept. 11 - Sept. 17: • 0 M-class flares • 0 C-class flares (only counted if associated with coronal mass ejections) • 17 coronal mass ejections • 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory shows the week’s activity. A quiet week on the Sun as a cluster of active regions move across the Sun’s disk and around the limb. As of Friday, Sept. 18, there are no active regions on the Earth-facing side of the Sun. The dark “strips” across the Sun that emerge towards the end of the video are coronal holes. These cooler bands of solar material on the Sun (which make them appear darker) are where the Sun’s magnetic field lines open up to space, allowing high-speed solar wind to escape.

Here are some fun facts about the comet!!! THE BERNOULLI X-FILES! (Yes Beaker is more of a Dana Scully type) Comet Tsuchinshan-ATLAS: 1.Discovery: The comet was discovered by two independent teams, one from the Purple Mountain Observatory (Tsuchinshan) in China and the other by the ATLAS (Asteroid Terrestrial-impact Last Alert System) in Hawaii, in early 2023. 2.Bright Comet Potential: C/2023 A3 has the potential to become one of the brightest comets visible in recent times. Traveler: The comet is moving at a speed of around 180,000 miles per hour (290,000 kilometers per hour), a breakneck speed as it journeys through space toward the inner solar system. 4.Close Encounter: At its closest approach to Earth, in October 2024, the comet will pass at a distance of about 70 million kilometers (43 million miles) from our planet. 5.Long Period: Tsuchinshan-ATLAS is considered a long-period comet, meaning its orbit around the Sun takes more than 200 years, though the exact length of its orbit is still being studied. 6.Sun-Grazing Distance: The comet will make its closest approach to the Sun, known as perihelion, in September 2024, coming within about 0.39 astronomical units (AU) of the Sun (about 58 million kilometers or 36 million miles), which is closer than the orbit of Mercury! Did you see the comet?

Billy Carson: "Something massive moved through our solar system & rearranged the planets - It's written about in ancient texts" He reveals the mind blowing match between ancient texts and our solar system's chaotic formation. Something huge moved through our solar system millions of years ago, capturing its own orbit around the sun. Saturn and Neptune switched locations due to gravitational forces. Uranus was flipped on its side, now orbiting north-south instead of east-west, as if it got tugged hard enough to turn sideways. This never stopped. It passed way beyond Pluto and created its own path. Modern astrophysicists and astronomers describe this exact process, and it's detailed in ancient texts about the creation of our solar system and Earth itself. It pushed Mercury closer to the sun, then Venus, placing us in the third spot. Mars was once a habitable moon of the larger planet Tiamat.

Elon Musk: Everything is solar power. The rest is noise. “The sun is about 99.8% of the mass of the solar system. Jupiter's about 0.1% and everything else is in the remaining 0.1%, and we are much less than 0.1%. So, if you burnt all of the mass of the solar system, then the total energy produced by the sun would still round up to 100%. If you just burnt Earth, the whole planet, and burnt Jupiter, which is very big and quite challenging to burn, turn Jupiter into a thermonuclear reactor, the sun is 99.8% of the mass of the solar system and everything else is in the miscellaneous category. Basically, no matter what you do, total energy produced in our solar system rounds up to 100% from the sun. You could even throw another Jupiter in, so we're going to snag a Jupiter from somewhere else, you could teleport two more Jupiters into our solar system, burn them, and the sun would still round up to 100%. As long as you're at 99.6%, you're still rounding up to 100%. Maybe that gives some perspective of why solar is really the thing that matters. And, as soon as you start thinking about things at a grander scale, like Kardashev Scale 2 civilizations, it becomes very, very obvious. I'm not saying anything that's new, by the way. Anyone who studies physics has known this for a very long time. In fact, Kardashev, a Russian physicist who came up with this idea, I think, in the 1960s, just as a way to classify civilizations, where Kardashev Scale 1 would be, you've harnessed most of the energy of the planet, Kardashev Scale 2, you've harnessed most of the energy of your sun, Kardashev 3, you've harnessed most of the energy of a galaxy. Now we're only about 1% or a few percent of Kardashev Scale 1 right now, optimistically. But as soon as you go to Kardashev Scale 2, where you're talking about the power of the sun, then you're really just saying everything is solar power and the rest is in the noise. Like, the sun produces about a billion times, or call it well over a billion times more energy than everything on Earth combined.” All-In Podcast, October 31, 2025

Why does the Sun throw stuff at us? The Sun’s surface is a churning soup of energetic electrons and ions called plasma. The motion of those charged particles creates magnetic field loops that are larger than the Earth. These loops twist, turn, and trap plasma. The featured time-lapse, taken over 2 hours on April 24th, 2026 by the Solar Dynamics Observatory, shows what happens when those magnetic fields become too stressed: they snap and expel billions of tons (trillions of kilograms) of plasma into space at millions of miles (or kilometers) per hour in what is called a coronal mass ejection (CME). The Sun releases a few CMEs each day when it is at the peak of its activity cycle, which passed in 2025. Some of these eruptions hit Earth and can disrupt power grids, disable satellites, and endanger astronauts, which is why space weather monitoring is so important.

🚨OFFICIAL: NASA Updates on 3I/ATLAS NASA just updated the official page for 3I/ATLAS. The page includes a tracking tool, that features the assets, and events listed below: NASA Assets Observing Comet 3I/ATLAS NASA's Hubble Space Telescope captured this image of interstellar comet 3I/ATLAS on July 21, 2025, when the comet was 277 million miles from Earth. Hubble revealed a teardrop-shaped cocoon of dust coming off of the comet's solid, icy nucleus. Because Hubble was tracking the comet moving along a hyperbolic trajectory, the stationary background stars are streaked in the exposure. Hubble’s continuing observations allow astronomers to more accurately estimate the size of the comet’s nucleus. Observations as of Aug. 20, 2025, indicate that the upper limit on its diameter is 3.5 miles (5.6 kilometers), though it could be as small as 1,444 feet (440 meters) across. NASA assets that are planning to gather observations of 3I/ATLAS include: Hubble, Webb, TESS, Swift, SPHEREx, Perseverance Mars rover, Mars Reconnaissance Orbiter, Curiosity rover, Europa Clipper, Lucy, Psyche, Parker Solar Probe, PUNCH, and ESA/NASA’s SOHO and Juice.

Here was the last planetary alignment shown in the coronagraph similar to the upcoming sequence early Jan 2026. Four planetary conjunctions in quick success with a comet impact as well and just afterwards a G4 geomagnetic storm hits Earth from some BIG CMEs. Notice the sunspot number increase from Oct to December 2006, a 4x increase!! Venus and Mars perform a double Cazimi and get some initial activity going as seen by the faint full halo CMEs (oct. 22-23, 31st). Then the comet impact (11/3-11/4 being another great example of a CME directly following a comet impact to the Sun) and Mercury's inferior conjunction further spice things up. Just as Jupiter goes Cazimi CME start blasting off like crazy from the western limb (left side) and then when they rotate Earth-direct BOOMSHAKALAKA. Solar Storm impacts at 900 km/s immediately sending Earth into G4 conditions for 6 hours. When you have the space weather, planetary geometry, and geophysics skillsets, the connections are clear as day to see.

Using Grok build, now we were able to cross the magnetosphere data (from ACE and Solar-1 satellites) which shown the magnetic field lines of the Earth .... with the BOM (bureau of meteorology Australia) magnetopause feed ------ the BOM shows the standoff distance of the edge of the magnetosphere ----- the area called the "magnetopause". Now we get to see the buffeting blasts of solar wind and charged particles when they hit Earth (coming from the sun). This then perturbs the electromagnetic field lines of Earth shown by ACE and Solar-1 -- and that vibration is carried on down to the CORE OF THE EARTH! Also added in the ability to turn off Earth (transparent) so we can see inside Earth down to the calculations most people never even get to see -- and see it get vibrated , plucked like strings on a guitar! The BOM data, as well as the ACE, and Solar-1 data are all real time, and can be set to update every 1minute to every hour! The projected trail of the magnetic field around Earth is just an approximation, but it set to also vibrate along with the BOM data showing the magnetopause compression / expansion when strong solar winds, or large particle storms hit. Simply put, summed up, using Grok we were able to rebuild the old school Japanese NICT site, make it fully 3D interactive, and add in the BOM to make a new form of data observation where both the magnetopause, and magnetosphere data are combined into one, displayed on the same screen at the same time!!!!!!!!!!!!!! Both feeds can be toggled on / off so as to view one or the other as well if the user wishes! I will release this to the public for free along with the Solar and Earthquake programs very soon!

THE SOLAR SYSTEM IS OFFICIALLY A HARDWARE STORE: DISMANTLING THE PLANETS TO POWER THE FUTURE The conversation about Dyson Swarms has shifted from science fiction to a logistical reality of "when," not "if". While covering the sun in a solid shell is a structural nightmare, a Dyson Swarm, a network of independent solar collectors, is the pragmatic path to a Type II civilization. Elon accelerated this timeline, suggesting Starship could deploy solar harvesting satellites delivering 100GW per year to Earth orbit within the next four to five years. But if we are talking about a true, star encompassing swarm, the 50 year sprint begins with Mercury as the ultimate sacrificial planet. It is metal rich and sits at the perfect distance from the sun to minimize energy costs for launch. Automated robots would mine Mercury’s crust, refine materials on site, and launch solar panels into a statite orbit using radiation pressure to maintain position. Disassembling just half of Mercury provides enough material for a swarm capturing a billion times more energy than Earth currently receives. Asteroids are the "fantastic food source" for this construction because they are a non starter for gravity wells. Mining an asteroid like 16 Psyche is infinitely more efficient than fighting the gravity of a planet like Jupiter. Most asteroids are already sorted into carbonaceous fuel or nickel iron kits, making them perfect modular factories for solar panels. While we harvest these dead rocks and the asteroid belt, habitable candidates like Mars will be left untouched. Source: Moonshots Peter H. Diamandis, MD

Earth Could Survive the Sun's Death: New Models Offer Hope 🟠 Our planet has a chance of surviving the Sun's transformation into a red giant and avoiding total destruction in its thermonuclear inferno. Earth's ultimate fate will be determined by a delicate balance between the gravitational pull of the swelling star and its loss of mass; as the star loses mass, its gravitational grip will weaken, allowing the planet to drift to a safer orbit. Astronomers from KU Leuven (Belgium) have revised predictions regarding the future of the Solar System. They conducted gravitational simulations that accounted for the internal structure of aging stars, and their findings were published in the journal *Astronomy & Astrophysics*. In approximately five billion years, the Sun will exhaust the hydrogen fuel in its core, causing it to expand hundreds of times in size and transform into a massive red giant. At that point, a "tug-of-war" will begin within the Solar System, the outcome of which will decide Earth's fate. On one hand, the star's massive expansion will generate powerful tidal effects that act to slow Earth down and drag it inward. On the other hand, the star will actively shed its outer layers into space via powerful stellar winds. As it loses mass, the Sun will become lighter and its gravitational grip will weaken, enabling Earth to migrate further out into the Solar System. Updated calculations indicate that the effect of the Sun's mass loss could counteract tidal drag; in this scenario, our planet would have time to shift to a more distant orbit lying just beyond the radius of the expanded star. To validate their theoretical calculations, the scientists turned to actual observations of the dying giant star L2 Puppis, located 200 light-years away. In the past, it closely resembled the Sun, but now it is rapidly losing mass and is surrounded by a dust disk in which a large planet orbits. The fact that this world survived gives scientists strong grounds to hope that Earth might also be saved. However, there is no cause for optimism regarding our own system's neighbors: computer simulations indicate that Mercury and Venus will inevitably be completely consumed by the flames of the dying star. The launch of the PLATO space telescope will help settle the debate about our planet's future once and for all. It is scheduled to enter orbit next year to search for exop всяlanets around aging stars. 🌙

Earth Could Survive the Sun's Death: New Models Offer Hope 🟠 Our planet has a chance of surviving the Sun's transformation into a red giant and avoiding total destruction in its thermonuclear inferno. Earth's ultimate fate will be determined by a delicate balance between the gravitational pull of the swelling star and its loss of mass; as the star loses mass, its gravitational grip will weaken, allowing the planet to drift to a safer orbit. Astronomers from KU Leuven (Belgium) have revised predictions regarding the future of the Solar System. They conducted gravitational simulations that accounted for the internal structure of aging stars, and their findings were published in the journal *Astronomy & Astrophysics*. In approximately five billion years, the Sun will exhaust the hydrogen fuel in its core, causing it to expand hundreds of times in size and transform into a massive red giant. At that point, a "tug-of-war" will begin within the Solar System, the outcome of which will decide Earth's fate. On one hand, the star's massive expansion will generate powerful tidal effects that act to slow Earth down and drag it inward. On the other hand, the star will actively shed its outer layers into space via powerful stellar winds. As it loses mass, the Sun will become lighter and its gravitational grip will weaken, enabling Earth to migrate further out into the Solar System. Updated calculations indicate that the effect of the Sun's mass loss could counteract tidal drag; in this scenario, our planet would have time to shift to a more distant orbit lying just beyond the radius of the expanded star.

Watch Juno zoom past Jupiter. NASA's robotic spacecraft Juno is continuing on its now month-long, highly-elongated orbits around our Solar System's largest planet. The featured video is from perijove 16, the sixteenth time that Juno passed near Jupiter since it arrived in mid-2016. Each perijove passes near a slightly different part of Jupiter's cloud tops. This color-enhanced video has been digitally composed from 21 JunoCam still images, resulting in a 125-fold time-lapse. The video begins with Jupiter rising as Juno approaches from the north. As Juno reaches its closest view -- from about 3,500 kilometers over Jupiter's cloud tops -- the spacecraft captures the great planet in tremendous detail. Juno passes light zones and dark belts of clouds that circle the planet, as well as numerous swirling circular storms, many of which are larger than hurricanes on Earth. As Juno moves away, the remarkable dolphin-shaped cloud is visible. After the perijove, Jupiter recedes into the distance, now displaying the unusual clouds that appear over Jupiter's south. To get desired science data, Juno swoops so close to Jupiter that its instruments are exposed to very high levels of radiation.
