The article highlights the top 12 space stories of 2025, including international cooperation to prevent satellite collisions, a sudden disappearance of a lake in Quebec, the James Webb Space Telescope's study of an interstellar comet, Earth's shortest days, and the return of Soviet and Russian spacecraft, with a focus on how political and technological developments shaped the year's space events.
Earth's rotation paused at a 19-hour day for nearly a billion years due to a rare balance between lunar and solar atmospheric tides, impacting atmospheric oxygen levels and delaying the rise of complex life, with subtle ongoing changes influenced by Earth's deep interior.
The article explains why we can't feel Earth's movement despite its high speeds, highlighting that Earth's steady, smooth motion and gravity keep us grounded, and that we observe Earth's movement through astronomical clues like day/night cycles and changing star positions.
Earth's gradual slowing of its rotation, caused by the Moon's gravitational pull, may have influenced the timing and pattern of Earth's oxygenation, particularly through its effect on microbial oxygen production during events like the Great Oxidation Event, by affecting the duration of daylight and microbial activity.
Earth's rotation is unexpectedly speeding up, making August 5, 2025, one of the shortest days on record by just 1.25 milliseconds less than 24 hours, a phenomenon scientists are still trying to understand, possibly linked to changes in Earth's liquid core or lunar influences.
This week in science news, Earth's days are slightly shortening due to lunar gravitational effects, giant moa birds may be resurrected through de-extinction efforts, Earth's poles are shifting because of large dams, and new cosmic structures like the 'Cosmic Owl' have been observed by the James Webb Space Telescope. Additionally, climate-related health issues such as hyponatremia are increasing with global warming.
NASA research suggests that the massive water reservoir of China's Three Gorges Dam has a measurable, though tiny, effect on Earth's rotation by shifting mass toward the equator, highlighting how large-scale infrastructure can influence planetary physics.
At the Republican National Convention, former rivals like Nikki Haley and Ron DeSantis endorsed Donald Trump, emphasizing party unity. Meanwhile, new studies reveal that melting ice is slowing Earth's rotation and affecting its axis, highlighting the profound impact of climate change.
New research indicates that climate change-induced ice melt is redistributing Earth's mass towards the equator, slowing its rotation, shifting its axis, and even affecting its inner core. This dynamic could eventually rival the moon's tidal forces in influencing Earth's spin, with significant implications for timekeeping and space navigation.
New research indicates that climate change is lengthening days by causing glaciers and polar ice sheets to melt, which redistributes water closer to the equator and slows Earth's rotation. This effect has accelerated since 2000 and could have significant implications for technologies reliant on precise timing, such as navigation and data centers.
A new study reveals that the melting of polar ice caps is causing Earth to spin more slowly, increasing the length of days at an unprecedented rate. This change, driven by the redistribution of mass from melting ice, could have significant implications for space and Earth navigation, potentially surpassing the deceleration effects caused by the Moon's gravitational pull by the end of the 21st century.
A new study reveals that human-caused climate change is melting polar ice, altering Earth's rotation, and lengthening days by milliseconds. This change, driven by the redistribution of meltwater from poles to the equator, is expected to accelerate, impacting technologies like GPS. The study highlights the profound influence of climate change on Earth's natural processes, potentially surpassing the moon's effect on day length.
Earth's slower rotation due to climate change may necessitate the introduction of a negative leap second, a first in history, to adjust universal time. The need for this adjustment has raised concerns among time meteorologists and experts due to potential complications for computing systems, as existing codes are not equipped to handle a negative leap second. While the exact timing of a negative leap second remains uncertain, it highlights the ongoing impact of climate change on Earth's fundamental processes.
Earth's rotation, which has been speeding up due to dynamics in the planet's liquid outer core, is now slowing down due to the impact of global warming on the polar ice caps. This is likely to delay the need for a deleted leap second until 2028 or 2029. The redistribution of mass from the poles to the world's oceans is causing the slowdown, counteracting the previous speed-up. This unprecedented event, caused by changes in the Earth's rotation, could have significant implications for precise timekeeping in today's interconnected world.
Timekeeping scientists are considering subtracting a leap second from atomic clocks to adjust for the Earth's faster-than-expected rotation due to climate change, marking the first instance of removing a second rather than adding one. The Earth's rotation has been gradually slowing, leading to the addition of 27 leap seconds between 1972 and 2016, but now the melting poles are causing the need for a negative leap-second correction as early as 2026. This adjustment has implications for systems reliant on precise timekeeping, such as GPS satellites and financial transactions, and highlights the complex relationship between atomic timekeeping and our understanding of time.
