Here's info on an old paper on star spot imaging that I was privileged to have contributed to: Imaging Stellar Surfaces via Matrix Lightcurve Inversion Article December 1996 6 Reads 📷Drish, W. F., Jr📷Robert O. Harmon·📷W. J. Wild·📷Robert Rosner· Matrix lightcurve inversion (MLI) is a method for deducing the appearance of a rapidly-rotating star's surface features (in particular starspots) from its photometric lightcurve. It has the significant advantage over "spot models" that no a priori assumptions are made regarding the number of spots on the surface or their shapes. We present here the results of an extensive set of simulations using synthetic lightcurves generated from artificial surfaces. These have allowed us to test the ability of MLI to reconstruct stellar surfaces under conditions in which the true surface features are known. We demonstrate that MLI represents a viable alternative to other techniques such as spot models and Doppler imaging, and is of particular value when used in conjunction with such techniques.

Comparing late stars that are red giants is not a proper comparison to blue giants. They are just not as massive as the blues

☀️☀️ The Sun compared to the stars Vega, Arcturus, and Rigel. Vega (α Lyrae) is a blue star located in the constellation Lyra. Arcturus (α Boötis) is the brightest star in the Northern Hemisphere's sky. It is an orange giant with a luminosity 110 times that of the Sun. Rigel (Beta Orionis) is the brightest star in the constellation Orion and the seventh-brightest star in the night sky.

Have you wondered … what is a star? In short, mostly a giant ball of hot gas. We're quite familiar with our star, the Sun, but there are many other types with different sizes, masses, ages, temperatures, and levels of brightness. Watch more:

Ever look up at the sun and think it’s yellow? Neil deGrasse Tyson explains that it is actually white. The only reason we see it as yellow or orange is because our atmosphere filters the light. It scatters away the blue wavelengths more strongly, leaving the warmer tones, especially when the Sun is low on the horizon. If the Sun were truly yellow, snow on Earth during the middle of the day would also look yellow instead of white. That is because sunlight defines how we see color in everything around us. It shows how what we perceive as reality is shaped by the interaction between light and the medium it travels through, rather than being a fixed property of the objects themselves.

Have you ever thought about how extremely unlikely it is that, despite the Sun being 400x bigger than the Moon, it appears the EXACT same size in our sky? The official NASA narrative is that this is simply because, in addition to it being 400x bigger than the Moon, it's also 400x further away. But the odds of this are infinitesimally small. What if...the Sun and Moon look like they're the exact same size, because they ARE the same size? Question everything, friends...

Babu Owino on between he and Sifuna, who is the boss: It is a conversation. Mr. Sun is the king of the day and shines during the day. Mr. Moon is the king of the night and shines at night. There is no competition in this thing; there is only completion. The sun does not affect the moon shining and the moon does not affect the sun shining. You need the moon and the sun to make a complete day, therefore it is not about competition, it is about completion of the job that we want to do, completion of our vision #CitizenSundayLive

Earth orbits the Sun, and the Sun orbits the center of the galaxy... but what is the Milky Way itself orbiting? The Milky Way is not orbiting a single object. Instead, it is moving around a shared center of mass alongside the Andromeda galaxy. While most of the universe is being pushed apart by dark energy, the gravity within our "Local Group" is strong enough to pull these two galaxies toward each other in a slow "cosmic dance." This movement isn't a clean, circular orbit; it is a direct path toward a massive collision and merger that will occur in about 4 to 5 billion years.

ELON MUSK: SKIP TINY FUSION, USE THE SUN "I think anyone who looks at the math can see that you can make a reactor that generates more energy than it consumes. The bigger you make it, the easier it is. In the limit, you just have a giant gravitationally contained thermonuclear reactor like the sun, which requires no maintenance and is free. So why bother making a little itty-bitty sun that's so microscopic you'd barely notice it on Earth when we've got a giant free one in the sky?" Source: Elon Musk

Elon Musk on how ridiculously small we are compared to the Sun: “We are like a dust mote compared to the Sun All of human civilization currently uses much less than a trillionth of the power emitted by the Sun Even if we increased our energy use by a million times, we would still be much less than a millionth of the Sun’s energy The Sun is 99.8% of the mass in the solar system. If you burned every single other planet and added two more Jupiters, the Sun would still round up to 100% of the energy in the solar system Everything is just extremely tiny compared to the Sun”

Most people believe that exposure to sunlight increases their risk of cancer. This is simply NOT true! We’ve been taught to fear the sun, and as a result, adults and kids are soaking themselves in a bath of toxic, hormone-disrupting chemicals. Science has long ago revealed that exactly what we put on our skin winds up in our bodies, and rapidly. What causes cancer is the ingredients of the sunscreens that we have been advised to use to "protect" us from the sun rays. The sun actually protects you against skin cancer in most cases, especially considering the powerful role of vitamin D in the body.

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

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.

Elon Musk explains the Kardashev Scale: "That's the most objective metric that any alien species, say, visiting us would calibrate how much progress we've made as a civilization, and one of the most objective ways to do that is the amount of power that any given civilization has been able to harness, and there was a Russian physicist, actually, who thought about this, and it's, I think, it's a good way to characterize it, which is you can have, you can assess how well a civilization is harnessing the power available on the planet, that's type I. And then type II would be how much of the star's power are you harnessing, and then type III would be how much of the galaxy's power are you harnessing. These are very objective and measurable numbers, so right now we're very low on the Kardashev I scale, like, what proportion of our planet's power are we harnessing, it's a very, very tiny number, and basically we're harnessing almost nothing of our stars' power, so the sun is truly an immense state. We don't even know how to do level III, really. AI will figure it out. One way to appreciate the size of the sun is to think about how heavy is the sun compared to all the rest of the mass in the solar system. So, the sun is about 99.86% of all mass in the solar system. It's everything, and then all the remaining 1.14% most of that is Jupiter, one planet."

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. 🌙

So in a nutshell, we have photo receptors in our eyes which send a signal to the brain to initiate production of melanin, which as you know protects the skin and an effect of that is we become more melanated (tanned). So when we wear sunglasses, we prevent that process from happening and that’s one of the main reasons people burn. So the main principles are we should be in the sun more often. One way we can reduce being burned is by sun gazing. Or basically going out into the sun early, whether sun ‘rise’ or super early before it’s too harsh. The eyes then initiate the melanin production, which has an effect on our hormones and links to vitamin D, TRY THIS IS WORKED FOR ME 🌞
