    Reading Time: 3 minutes Earth has been spinning since its birth four and a half billion years ago. It was formed from the debris created when the Sun was formed by the collapse of a large cloud of material. Earth-turned debris orbits the sun, and the water around the bathtub drain surrounds itself when you empty the shower. Our planet continued to orbit the Sun after its formation, and will continue to do so for a long time. The Earth rotates continuously every 23 hours and 56 minutes. During this time, the Earth also moves a short distance in its orbit around the Sun, which lasts about a year. That means it has to turn a little more until it faces the sun again – for four minutes. That is why a day on earth lasts 24 hours. If the Earth continues to rotate, there is practically nothing to stop it. If you spin a top in school, it will eventually stop. That’s because as it spins, the air and surface of the playing field exert pressure, causing friction and...
    (CNN) — June 29 was the shortest day on Earth since the invention of the atomic clock. The planet’s rotation measured in at 1.59 milliseconds short of the normal 24 hours, according to the International Earth Rotation and Reference Systems Service, an organization in charge of global timekeeping. A rotation is the length of time the Earth takes to spin once on its axis. The previous record was on July 19, 2020, when the day measured 1.47 milliseconds shorter than normal. The atomic clock is a standardized unit of measurement that has been used since the 1950s to tell time and measure the Earth’s rotation, said Dennis McCarthy, retired director of time at the US Naval Observatory. Despite June 29 breaking a record for the shortest day in modern history, there have been much shorter days on Earth, he said. When dinosaurs still roamed the planet 70 million years ago, a single day on Earth lasted about 23½  hours, according to a 2020 study published in Paleoceanography and Paleoclimatology. Since 1820, scientists documented Earth’s rotation slowing down, according to NASA....
    Our earth rotates once every 24 hours. This is how the Duration that day. However, the reality is a bit more complicated. Because our planet is not very stable.

As a result, June 29, 2022 is the shortest day on record Atomic clocks. The day in question was 1.59 milliseconds short, so it went completely unnoticed. 24 hours Classic. This is still less than the record for the shortest day recorded on July 19, 2020. Then it was a question of 1.47 milliseconds less than 24 hours. This record was also broken again on July 26, 2022.

    Amid all the hustle and bustle of modern lives, it may often seem like time is flying. But it turns out it really is, after Earth recorded its shortest day since records began in June.  The 1.59 milliseconds shaved off the usual 24-hour spin on June 29 raises the prospect of a negative leap second having to occur to keep clocks aligned — which would be the first time in history that global clocks have been sped up. So just why is Earth spinning faster than usual? Scientists claim climate change, seismic activity and ocean circulation could all be to blame, as could the pull of the moon and the so-called 'Chandler Wobble' — a change in the spin of the Earth on its axis.  The 'Chandler Wobble'  The 'Chandler Wobble' is a wobbling motion that happens as the Earth rotates on its axis. It works in a similar way to how a spinning top wobbles as it slows down.   However, in recent years the spin has become less wobbly, which scientists think might be linked to the increasing speed of the...
    Earth's rotation speed has markedly increased, enough that it shortened a day in June this year. June 29 was 1.59 milliseconds shorter than the average day, which is 86,400 seconds. The trend could continue, according to scientists. Scientist Leonid Zotov of Lomonosov Moscow State University recently published a study on the rotation of the Earth. Zotov speculates that the Earth's tides could be causing the fluctuation of the planet's rotation.

(NASA via AP) "Since 2016 the Earth started to accelerate," Zotov said in an interview. "This year it rotates quicker than in 2021 and 2020." Should the Earth continue to accelerate its rotation, one solution will be to add a "leap second," meaning clocks could skip or add seconds. The idea was first introduced in 1972 by the International Earth Rotation and Reference Systems Service. There have already been 27 alterations to Coordinated Universal Time. Tech...

    Some asteroids can 'sneak up' on us thanks to a quirk of the Earth's rotation that makes them seem like they are barely moving — making them hard to detect. This is the warning of NASA-funded experts who investigated how telescopes nearly missed a 328-feet-wide asteroid that came within 43,500 miles of Earth back in 2019. The space rock, dubbed '2019 OK', was the first object of its size to get that close to our planet since 1908 — but it was only spotted 24 hours before its closest approach. The reason, the team determined, is because it was moving towards us in such a way that its motion across the night sky was counteracted by the Earth's spin. Thus — to early warning systems like Pan-STARRS1 at Hawaii's Haleakala Observatory — 2019 OK looked stationary, so did not set off the automated detection software. In fact, the experts said, up to half of asteroids approaching Earth from a danger zone east of 'opposition' likely undergo periods of such apparent slow motion. (An asteroid is said to be at opposition when its position...
    The earth not only revolves around the sun, but also orbits itself towards the east. There are good reasons for this. If the earth did not orbit the sun every 365 days, we would not have seasons. If that too did not rotate on its axis, our days would not be 24 hours. But it would not be so bad if the earth did not rotate even for a second. A Thought test: The earth suddenly stops spinning. “It’s catastrophic,” said Neil de Cross Tyson, an American astronomer and television presenter. In an interview. At that time, anything that is not much connected to the earth will tear from the ground at the speed at which the earth rotates. How fast can it be? The earth stops, we fly At the equator, the Earth is approx At 1,674 km / h – i.e. about 465 meters per second – its maximum rotational speed. The further north or south you are, the slower the rotation speed. The 50th degree of northern latitude – running across Germany – is...
    Earth is spinning faster than it was half a century ago, and if it continues speeding up scientists say they may have to remove a second from the atomic clock.  The speed our planet rotates on its axis has varied throughout history. In fact, Earth rotated 420 times per year millions of years ago, but now does so 365 times. However, sometimes the speed of rotation varies slightly, affecting the global timekeeper - the atomic clock - requiring leap seconds to be added when the world runs slightly faster.  Now, UK National Physical Laboratory scientist, Peter Whibberley, has warned that if the rotation rate increases further, a negative leap second may be needed.   Earth is spinning faster than it was half a century ago, and if it continues speeding up scientists say they may have to remove a second from the atomic clock THE EARTH ROTATES ON ITS AXIS OVER 365 TIMES EACH TIME IT ORBITS THE SUN The rotation of the Earth, or its spin around its own axis, has varied over the 4.6 billion year history of our world....
    A white dwarf star has broken records after scientists discovered that it completes a full rotation once every 25 seconds. The star, called LAMOST J024048.51+195226.9 (or J0240+1952 for short), was analysed by researchers from the University of Warwick, who say it is the fastest spinning confirmed white dwarf. The previous record holder was a white dwarf that completed a rotation in just over 29 seconds, making J0240+1952 20 per cent faster. Dr Ingrid Pelisoli, who led the study, said: 'J0240+1952 will have completed several rotations in the short amount of time that people take to read about it, it is really incredible.'

Stars larger than 10 times the mass of the sun suffer a violent supernova at the end of their lives, but a more gentle end awaits sun-like stars.  When stars...
    Life on Earth depends on oxygen, everyone knows, but how did it come about? Is it related to the day-night rhythm of the planet? Researchers study bacteria in a lake in the United States. This is a fundamental concern for everyone, says Gregory Dick, professor of microbiology at the University of Michigan, with a blink of an eye: “What are the conditions that support life like ours?” This question was sent to him and his colleague Judith Claude, to the Max Planck Institute of Marine Biology, in what is known as the “Ancient Earth.” Earth formed about 4.54 billion years ago, with a margin of error of about 50 million years. Traces in rocks and fossils indicate that the first signs of life on the planet are about 3.5 billion years old (all of which are only estimates based on evidence collected to date). As far as the life we ​​know is biological life, it may have started after a while. Probably another billion years later, in the very depths of the oceans, microbes called “Extramobiles” thrive. Scientists believe that...
    Earth began to have an oxygen-rich atmosphere about 400 million years ago 4.5 billion years ago the Earth’s rotation lasted only six hours Research answers why there were large increases in oxygen on our planet Oxygen has allowed life to prosper and become more complexBut there was a time, 3 billion years ago, when it was very rare. “The increased oxygen is probably the greatest environmental change in the history of our planet“Says geologist Woodward Fischer in a Science paper that echoes a new hypothesis published in Nature Geoscience about the exponential increase in oxygen on Earth. The Earth rotates on itself in a rotation that lasts 24 hours, which gives rise to the days and nights. This is something that we learn as children but that has not always been the case. Scientific models estimate that 4.5 billion years ago the day only lasted 6 hours. Thanks to the pull exerted by the Moon on us, that speed of rotation slowed down to 21 hours 2,400 years ago. And so it remained until a new gravitational force...
    If half a moon is located at the current distance; The rotation of the earth will be very slow, and this will lead to a change in the length of the day and the hours of night and day. The moon orbits itself and the earth. Astronomers who have been studying it since ancient times know this. But what if the distance between the Moon and it and the Earth is halved to what it is today? In a statement released by “Live Science” (Direct science) On July 19, explained by Neil Cummins, a physicist at the University of Maine in the United States; “The Moon’s greatest influence is its attraction to Earth’s oceans, which control the waves throughout the day and year.” But if the Moon were closer to half the distance of the Earth today, the wave would be 8 times larger. “Some islands will be completely underwater for most of the day, and the beaches where people live may become uninhabitable due to the high tide,” Cummins added. Scientists believe that as the Moon approaches (pixie) the...
    The Earth has been spinning unusually fast in recent years, especially during the last year, which was a very difficult year for all of humanity. 2020 included the shortest 28 days since 1960, and is projected to the year 2021 will be even worse, possibly the shortest year in decades. Earth is an excellent timekeeper: On average, relative to the Sun, it rotates once every 86,400 seconds, which is equivalent to 24 hours, or an average solar day, but it is not perfect. When high-precision atomic clocks were developed in the 1960s, they showed that the length of an average solar day can vary in milliseconds (1 millisecond equals 0.001 seconds). These differences are obtained by measuring the rotation of the Earth with respect to distant astronomical objects and using a mathematical formula to calculate the mean solar day. Before 2020 began, the shortest day since 1973 was July 5, 2005, when the Earth’s rotation took 1.0516 milliseconds less than 86,400 seconds. In 2020 the Earth accelerated But in mid-2020, Earth broke that record no less than 28 times. The...
    The atomic wall reveals that the rotation speed of the earth varies – and we enter many faster days. When you say “oh what a day went by fast”, in some cases you may be more right than you think. The speed of the Earth’s equator is 1,674.4 km / h or 465.10 m / s. A cycle of 86,400 seconds gives 24 hours, but sometimes the rotation speed actually increases, which decreases the day. It writes Time and date. Many factors are thought to contribute to the varying speed of the planet’s rotation, somewhat happening in the molten center, but the oceans and our atmosphere. With the right atomic clocks, we were able to reveal just how big and often these variations occur. It turns out that in 2020 the speed was unusually high. The previous milestone in the future was July 5, 2005. Then that day was 1.0516 milliseconds shorter than the scheduled 86,400 seconds, giving it the shortest day since 1973. But did not strike in 2020 with speeds below 28, which, among other...
