"General relativity imposes a speed limit on objects moving through spacetime. Nothing with mass can reach the speed of light. This is an absolute, uncancelable prohibition. The energy required to accelerate a massive object to the speed of light is infinite. Period. "

"Based on this, very, very precise studies of the periods of over 60 millisecond pulsars have been conducted for many years. And this network is called PTA. It's PTA not like Polish Astronomical Society, but like Pulsar Timing Array is a network. And what is very important, recently the first works appeared showing that this network, this network provided evidence for the existence of such a gravitational background, that there are such waves that spread everywhere, very long waves, which cause the frequencies of impulses from pulsars reaching us to be minimally distorted and they are directionally correlated, right? "

"In 2003, nature gave us an even better natural observational instrument, namely not just one pulsar orbiting a center of mass with a neutron star, which is something invisible, but it gave us something immeasurably more accurate, which is two clocks orbiting, that is, a double pulsar this time J0737-3039. "

"We see stars orbiting invisible points at immense speeds, such as the S-stars in the center of our galaxy. We see accretion disks, gas heated to millions of degrees, falling onto something that does not reflect light. We detect gravitational waves that perfectly match models of colliding black holes predicted by Einstein. "

"Meanwhile, on the surface in Jezero Crater, the Perseverance rover was waiting. And Perseverance pointed its cameras at the sky and took a long exposure. And in the photos, Atlas looks like a faint smudge drifting among the stars. It may not be the most beautiful photo in the history of astronomy, let's not kid ourselves, but its scientific and historical significance is gigantic here. This is the first portrait of a visitor from outside the solar system, taken by a robot standing on another globe. "

"Apophis is that famous asteroid that will fly extremely close to Earth in 2029, closer than geostationary satellites. A probe will study how Earth's gravity will affect this asteroid during such a close flyby. "

"On 24 September 2023, at 4:42 a.m. MDT, at a distance of 63,000 miles (101,000 kilometers) from Earth, it ejected the sample return capsule, which re-entered the atmosphere at 27,650 miles per hour (44,500 km/h). "

"Chinese scientists announced a success we've been waiting for since the 1960s. In a reactor in the Gobi Desert, they not only managed to start a chain reaction but did so in a system using molten salts and thorium. "

"The Chinese have successfully completed a full energy cycle, from thorium, through the breeding process, to obtaining energy from generated uranium 233. "

"The biggest advantage of thorium reactors is efficiency. In a traditional uranium reactor, we burn only a small fraction of the fuel. The rest is essentially waste. In the thorium cycle, we can burn almost all the fuel, which means we extract significantly more energy from the same amount of material. "

"In a reactor, this process is called fuel breeding. We need to take a thorium atom and hit it with a neutron. Then thorium 232 turns into thorium 233. And this isotope is unstable and quickly decays to protactinium 233, and this in turn after another decay becomes uranium 233. "

"Webb telescope, which also observed this comet, detected methane in Atlas. Scientists using the James Webb telescope for the first time detected methane released from the interstellar comet or Atlas and there is a surprisingly large amount of it, similar to the amount of carbon dioxide there "

"almost half of everything orbiting Earth is space debris, abandoned rocket parts and so on, and so on. In fact, 47% of all objects that currently orbit Earth are space debris. "

"waste accumulates faster than it is removed. "

"Kessler syndrome is precisely that state in which satellites begin to uncontrollably break apart from each other, from the debris of others, and simply suddenly a gigantic cloud begins to form around the Earth. "

"the total volume of observed objects is 50,900 different objects. And where can one think of so many objects? After all, we haven't sent that many satellites into space. "

"almost half of everything orbiting Earth is space debris, abandoned rocket parts, and so on. Actually, 47% of all objects currently orbiting Earth are space debris. "

"Every night the telescope generates about 20 TB of raw data. No human team would be able to manually review, catalog, and analyze such a flood of information. It would take thousands of scientists centuries. That's why engineers have created fully automated data pipelines, which are algorithmic systems that continuously filter, calibrate, analyze images, and immediately flag moving objects or those that change their brightness, without human involvement. "

"Engineers had to construct something absolutely unprecedented in the history of optics. The largest digital camera ever built by man. This camera is the size of a large passenger car and weighs almost 3 tons, and its heart is a gigantic CCD sensor. "

"The Vera C. Rubin Observatory, previously known as LSST, or Large Synoptic Survey Telescope, is an absolute breakthrough in the history of astronomy. Instead of targeting one object and capturing its light for many hours, this instrument scans the entire visible sky night after night and in this way creates a multi-year time-lapse film, on which we see a dynamic and changing universe. "

"The main goal of this telescope is to solve the problem of our blindness to time-variable phenomena. Well, classical astronomy is based on the assumption that stars in the sky are constant and unchanging. What we see today will be there tomorrow, in a year, in 10 years, and so on, but the universe is full of violent, unexpected events. "

"In any case, in 1965, such a reactor was launched into space. Space Nuclear Auxiliary Power Shot Snapshot, an American military technology satellite, was used to test an ion engine powered by the Snap 10 reactor, and was the only nuclear reactor launched into space by the United States and the first reactor to operate in space in history. "

"Great Dark Spot. It turned out that not only Jupiter has its Great Red Spot, because it was within this dark spot that 2000 km/h was recorded. 2000 km/h. Well, these are winds in the most extreme hurricanes on Earth. That's up to 200 maybe kilometers, but that's already an extreme. "

"Pioneer. Look. No, Voyager. Look. Voyager. It showed us beautiful rings around Jupiter. Yes, but they are not visible with Earth telescopes. They are too faint, too weak. "

"Voyager just showed us this separation of the rings very much, but the F ring, it has been mechanically explained to this day, right? Because there are two moons that act in such a way that the F ring consists of two rings, like two strings, that form such a mutual arrangement, such a braid, such a thing, that's what I'm saying: "Jesus, how is it possible for such a braid to exist in natural conditions. "

"observing star occultations, drops in brightness were observed, but it wasn't known how this ring system looked. But you know, it could have been Russell's teapot. We weren't sure until that moment that these were actually rings, until Voyager flew by, took photos at so-called high ISO, and it turned out that when astronomers brightened them, beautiful rings simply appeared there.
