"Its empty weight is 2700 tons, but when the launch platform and the SLS rocket are placed on it, the mass increases to 6000 tons. It's a movable island with dimensions of 40 by 35 m, which is roughly the size of a basketball court. "

"The spectrum of this galaxy shows no characteristic lines for heavy elements. There is no trace of carbon or oxygen. Instead, the James Webb Telescope recorded something very rare, a signature of ionized Helium. "

"For decades, we have been searching for traces of the first objects that illuminated the absolute blackness of the early universe. Now, thanks to the power of the James Webb Telescope, we are probably looking directly at the pioneers of the cosmos, at stars that were born from pure primordial hydrogen-helium gas. "

"We are entering a new era of astronomy where the theoretical dark times, the cosmic dark ages, cease to be a mystery to us. Thanks to instruments like James Webb, we stop just guessing what the beginnings of light looked like or simply relying on calculations. We are starting to see them with our own eyes, and what we discovered in Hebe is just the beginning of the journey to a full understanding of our own genesis recorded in atoms that billions of years ago were forged in the hearts of these blue giants. "

"Mark One will carry two NASA science and technology payloads this year as part of the CLPS initiative, Commercial Lunar Payload Services. This is again also such an interesting NASA program, where private companies can also transport, but not people, only various systems, right? various goods, various experiments, various, I don't know, rovers, landers, whatever. Yes, we can send everything there as part of such a program, just not a human. "

"The exoplanetary object LHS 3844B observed by the James Webb Space Telescope is a so-called super-Earth, about 30% larger than our planet and located almost 50 light-years away from us. Unlike most exoplanet studies, which focus on atmospheres, astronomers analyzed the heat emitted from the planet's surface. "

"Many astronomers were initially reluctant to accept this conclusion. But the observations were so unambiguous and the interpretation so straightforward that they soon realized Rubin had to be right. The luminous stars are only the visible tracers of a much larger mass that makes up a galaxy. The stars occupy only the inner regions of an enormous spherical “halo” of unseen dark matter that comprises most of a galaxy's mass. "

"“We detected gamma rays with a photon energy of 20 gigaelectronvolts (or 20 billion electronvolts, an extremely large amount of energy) extending in a halolike structure toward the center of the Milky Way galaxy. The gamma-ray emission component closely matches the shape expected from the dark matter halo,” said Totani. “The fact that it's exactly at 20 GeV matters a lot, because it fits the predictions from the annihilation of WIMPs.” "

"“We detected gamma rays with a photon energy of 20 gigaelectronvolts (or 20 billion electronvolts – an extremely large amount of energy) extending in a halo-like structure toward the center of the Milky Way galaxy. The gamma-ray emission component closely matches the shape expected from the dark matter halo,” said Totani. The measured gamma ray energy spectrum, which describes how the intensity of the emission varies, closely matches model predictions for the annihilation of hypothetical WIMPs with masses roughly 500 times that of a proton. "

"Totani, however, employed a clever strategy. He ignored the dazzlingly bright center of the Milky Way, where too much is happening to extract anything from it, and focused on the galactic halo. What he discovered was an excess of Gamma radiation that forms a spherical shape surrounding our galaxy. "

"The latest experiment has just provided hard evidence that these so-called virtual particles are very real and are key to understanding what empty space truly is. "

"The strong interaction is the most powerful of the four fundamental forces of nature, namely gravity, electromagnetism, weak interactions, and precisely these strong ones. It is what makes quarks, these tiny particles that protons and neutrons are made of, hold together so tightly that they are practically inseparable. "

"The mathematics behind virtual particles agrees because their presence affects measurable phenomena. Such an example could be a subtle change in the electric field around an atomic nucleus, which scientists can measure with great precision. or for example the Casimir effect, where the pressure of these seemingly non-existent virtual particles causes two plates to come together. "

"In this experiment, spin was key because it allowed scientists to trace the history of particle creation. It turned out that the spins of lambda particle pairs are correlated. "

"When we break the connection between them, the breaking energy is so powerful. I remind you, here it works the other way around than in electromagnetism, so we add energy to break such quarks, so there is something to form new particles from later. So it is so great and so powerful that it materializes as new mass, i.e., a new particle. "

"If you try to pull it out of the embrace of its companions, using, for example, enormous energy, nature will do something amazing. Instead of allowing you to isolate a quark, the energy you put into stretching this string will become so great that the string will simply break, and at the point of breakage, the energy will transform into a new particle-antiparticle pair. "

"Here we have the sun on the other side, so actually at this moment we have a transit, and actually at this moment you could study the Earth's atmosphere, because sunlight passes through it. You would see what is missing in the spectrum of this light and you would already know what you will find in the Earth's atmosphere. And here we would certainly find various gases such as CFCs and so on, which are also technosignatures, because they do not occur much in the real world. "

"the sound suppression system and so on. where that water flows out later and so on, where all those exhaust gases are ejected, you know. Because for that launch platform to withstand such acoustic stresses, because there's a huge acoustic wave there, so a mechanical wave actually, that hits, well, all these elements here, so that it survives as much as possible intact, so that afterwards there's only some renovation, and not rebuilding it from scratch. "

"in such large buoyancy pools, so-called laboratories, spacesuits are weighted in such a way as to balance the buoyancy of the water with the load. And when we balance that, they are practically in a state of weightlessness. And now, if we add a little more of that load, we can simulate gravity on the moon, which will be lighter, although it will be something, right? S times less than on the surface of the Earth. "

"a new feature, among many other things, was also the toilet on board, costing over 20 million dollars, which stopped working, but only the urine disposal system stopped working, because these are two separate systems. Solid waste, meaning feces, is simply deposited in a tank, similar to what happens on the ISS and so on. Such tanks with everything are later simply thrown away, right? However, urine was collected by a system that was supposed to eject it outside. So, urine crystals accelerated to tens of thousands of km/h then flew and are still flying through space. But something happened there. It's not entirely clear what. I haven't found information yet on what specifically caused the damage, but probably one of the fans that was supposed to create a vacuum. "

"generally, Nikon is NASA's choice and it's often in missions, and there was a Nikon 5D or D5, I think it's called, and the second one was a Nikon Z9. Wait, let me check, so I don't quietly, so I don't mislead here, but wait. Nikon Z9, I think. I think they took a lot of pictures, and the ones available on the websites are already selected pictures, you know. Oh, you see. This is it, this is not an advertisement. We are simply showing what NASA chose. They chose the Nikon Z9. This is just the body, as you can see, it costs about 20,000 PLN. And the Nikon Z9 is going to be, my dear, as they say, chosen as the camera for taking pictures on the surface of the Moon. Nikons simply do very well in these conditions of elevated radiation, yes, in space and so on. The Z9 is also mirrorless, so that's also very important, because fewer mechanisms that can directly expose the sensor, right? And fewer things can break, "

"Ingenuity was an absolutely pioneering project. in 2021 it proved that controlled flight in the thin Martian atmosphere, with a density of merely 1% of our Earth's atmosphere, is possible at all. It performed as many as 72 successful flights over nearly three years. "

"The first stage of the New Glenn rocket continued a parabolic flight, briefly soaring into space, then headed towards the Blue Origin platform in the Atlantic Ocean. Almost 640 km southeast of Cape Canaveral. Restarting its engines for two braking maneuvers, the launch vehicle settled onto the ship's deck, landing in an atmosphere of smoke, but accurately, less than 10 minutes after launch. "
