"The star, though small, is so violent that studying the atmospheres of its planets is an incredible challenge. Astronomers have studied this system multiple times, but without success. Now, a dozen additional observations have been planned using the James Webb Telescope, so we will soon learn more about this. "

"3 Sigma means that the probability that a given signal is just random noise is really minimal. It's like flipping a coin and getting heads 10 times in a row. Well, we start to have great certainty that the throws are not random and there's something going on, even though it can, of course, happen. "

"If you look at our model, it's white, isn't it? The whole hull here, everything is white, and what you see here is also white, and we see a difference in Albedo, which is the ratio of reflected light that falls on the surface, regarding the Moon and our Orion. "

"We have MaxQ at this moment. At this moment, the most powerful aerodynamic forces will act on the rocket. "

"ICPS RL10 engine fires to boost the spacecraft in a higher orbit around the Earth (from 16 miles to 100 miles). When Orion reaches the highest point of its trajectory, the Interim Cryogenic Propulsion Stage, or ICPS, upper stage will fire its engine to raise its perigee to a safe altitude of 100 miles. Once this burn is complete, Orion and the ICPS will be in a stable low-Earth orbit. A system check at 42 hours after the mission began to ensure the orbit was correct, ranging from (112 miles) 185 km at the closest point to Earth and 1,616 miles (2,600 km) at its highest point. "

"The ninth and penultimate full day on orbit is preparation for return. Astronauts will refresh procedures for atmospheric re-entry and safe ocean landing. "

"Radio communication with Earth will naturally be cut off for a period of 30 to 50 minutes when the spacecraft physically hides behind the Moon, which will simply block radio waves. "

"Approximately 49 minutes after launch, it will start its own engine to raise the orbit's perigee to a safe altitude of 180 km above Earth's surface. "

"This short propulsion impulse is necessary to place Orion in perfect orbital geometry before the most important maneuver, i.e., translunar injection planned for day two. "

"Using available on-board materials and stored supplies of the ship, astronauts will practice in practice the construction of a physical radiation shelter. "

"Approximately three hours after the mission begins, NASA will check Orion's piloting characteristics. This is due to the fact that in future more complex missions, this spacecraft will have to dock with other objects in orbit. "

"When the demonstration ends, the ICPS stage will fire its engines for the last time, performing a deorbit maneuver that will send it to a pre-planned burn-up over the Pacific Ocean. "

"landers are to be reusable. I'm talking about Starship HLS version, the human landing system that is to land on the moon's surface and then take off. So reusability, creating a foothold at the south pole for a lunar base as part of the program. "

"A rather radical concept. Let's burn the disease with fire in this case, meaning let's use the higher activity of our sun, because it turns out that paradoxically it is easier to protect oneself from higher solar radiation than from even moderate but cosmic radiation. "

"The European Space Agency (ESA) in a communiqué sent to PAP called these findings the radiation paradox. Very nice. Until now, space missions were planned so that astronauts would not be exposed to radiation associated with violent solar activity, but on the way to the Moon or Mars, they are also threatened by radiation originating outside the solar system, for example, as a result of a supernova explosion. "

"Ironically, the radiation drop is caused by increasing solar activity. Solar Cycle 25 has roared to life faster than forecasters expected. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down. "

"Currently, the foundation of our understanding of time and space is the general theory of relativity formulated by Albert Einstein. In Einstein's theory, time and space are not built absolutely from anything tangible. They are simply a mathematical continuum consisting of infinitely many points. "

"A quasicrystal is a completely different pair of shoes, because it also obviously has such a distinct pattern, and a certain kind of geometric order, but this pattern never, absolutely never, repeats exactly. Instead, it replicates itself in an infinite variety of subtle and delicate variations of itself. "

"Its authors put forward the claim that time and space have an internal crystalline structure, but not just any. It is a structure of a peculiar kind of crystal, professionally called a quasicrystal. "

"Albert Einstein's General Theory of Relativity, published in 1915, is the foundation of modern physics. It has long helped scientists understand the forces of gravity. [...] After 30 years of precise measurements, scientists managed to uncover the mystery of a star's movement around a supermassive black hole. Their discovery proved that Einstein, not Isaac Newton, was right. "

"there are no particles that normally exist in our reality that have a charge of plus 2, right? The electric charge is either plus 1, or minus 1, or there are two particles, or two of those, or two of those. "

"What is a quark? Well, I guess we know, because it is a fundamental particle that is supposed to form protons, neutrons and other strange particles in larger configurations. "

"In September 2022, the eyes of the entire astronomical and scientific world were focused on the finale of a mission that sounded crazier than a high-budget Hollywood movie script or even a more standard research project. "

"Although the DART probe's mass was only about 600 kg, which is literally a fraction of a permille of the target asteroid's mass, its speed in a fraction of a second before impact exceeded 22,000 km/h. "

"The target of this precise, historical shot was a fascinating object, a double asteroid system. The research team leading the mission targeted a relatively small asteroid, measuring only about 160m in diameter, named Dimorphos. "

"The smaller Dimorphos orbits the powerful Didymos with the precision of a Swiss watch, and thanks to this mechanism, any anomaly and change in the time of this short orbit would be immediately visible to our advanced astronomical devices. "

"Understanding this subtle gravitational dynamic of the barycenter was absolutely essential for NASA, for NASA engineers, because they knew that by precisely hitting the small Dimorphos, they would irrevocably affect this complex distribution of forces in this entire duo dancing in deep space. "

"Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected an unusually large amount of the organic molecule methanol in the interstellar comet 3I/ATLAS, revealing chemical conditions unlike those found in most comets of our own Solar System. The observations show that 3I/ATLAS contains significantly more methanol than hydrogen cyanide, unlike nearly all previously studied comets. "
