July 9 might be shortest day in history
(NewsNation) — July 9 might seem like an ordinary day on planet Earth. However, it could turn out to be the shortest day on record. The Earth was rotating unusually fast Wednesday, making the day between 1.3 and 1.6 milliseconds shorter than the normal 24 hours, New York Post reported. Buck Moon, 'Swift Planet' and more: How to enjoy July's night sky events Earth has experienced a new shortest day on record each year since 2020. The previous record holder for the shortest day ever was July 5, 2024, which was 1.66 milliseconds shorter than the typical 24-hour day, according to Time and Date. Scientists have been examining the issue and could even be forced to subtract a second from clocks, something referred to as a negative leap second, The Associated Press reported. 'This is an unprecedented situation and a big deal,' Duncan Agnew, a geophysicist at the University of California, San Diego, said in March 2024. 'It's not a huge change in the Earth's rotation that's going to lead to some catastrophe or anything, but it is something notable. It's yet another indication that we're in a very unusual time.' The Moon has always indistinctly affected the planet's spin through tidal braking. This leads to the Moon's gravitational pull causing our planet to bulge, as well as creating the tides, and resulting in Earth slowing down by around 2 milliseconds per century. Per the International Earth Rotation and Reference Systems Service, the shortest day of the year could be July 9, July 22, or August 5. All of these days mark when the moon is farthest from the Earth. The Associated Press contributed to this report. Copyright 2025 Nexstar Media, Inc. All rights reserved.

The Earth Is Spinning Faster—Here's Why July and August Will Have Record-Short Days
While the shortest day of the year typically falls in winter, summer will have its fair share of abnormally short days this year. According to TimeandDate, Earth will spin unusually fast in July and August, resulting in shorter days. From the point of view of the sun, it takes Earth roughly 86,400 seconds (24 hours) to complete one full rotation. This changes slightly from day to day, and these small variations are measured with atomic clocks. The number of milliseconds above or below 86,400 seconds is referred to as length of day. Until 2020, the shortest length of day ever recorded was -1.05 milliseconds, meaning it took the Earth 1.05 milliseconds less than 86,400 seconds to complete one rotation. Since then, Earth has beaten this record every year, with the shortest day of all being -1.66 milliseconds. This month,TimeandDate reports that Earth will get close to its previous record. On July 9, the length of date is expected to be -1.30 milliseconds, followed by -1.38 milliseconds on July 22 and -1.51 milliseconds on August 5. "Nobody expected this," Leonid Zotov, a leading authority on Earth rotation at Moscow State University, told the outlet. "The cause of this acceleration is not explained." Zotov added that most scientists believe it is something inside the Earth. "Ocean and atmospheric models don't explain this huge acceleration," he said. Despite this acceleration, Zotov predicts that Earth will slow down soon. "I think we have reached the minimum," he told TimeandDate. "Sooner or later, Earth will decelerate." In the meantime, scientists will continue to study the reason behind Earth's length of day variations. Read the original article on Martha Stewart

One of shortest days on record expected this month as scientists warn Earth's rotation is ‘unexpectedly' speeding up
EARTH is set to have three unexpectedly shorter than average days in the coming weeks - and it's taken scientists by surprise. The first of the shorter days will take place next week. 1 It's likely all thanks to the Moon, according to Popular Mechanics. The dates fall when our lunar satellite will be its furthest from Earth's equator. This can impact the rate of the Earth's rotation, which causes slight variations in the length of a day. Although experts have not yet confirmed the cause of the change. The International Rotation and Reference Systems Service has found that 9 July, 22 July, and 5 August will be the shortest days since 2020. As much as 1.51 milliseconds will be shaved off the clock, according to a experts. While that doesn't seem like much, and won't be noticeable, scientists say it's a pretty significant time jump. 'Nobody expected this,' Leonic Zotov, Earth rotation expert from Moscow State University, told 'The cause of this acceleration is not explained. Most scientists believe it is something inside the Earth. "Ocean and atmospheric models don't explain this huge acceleration." The shortest day recorded since 2020 was 5 July, 2024, which was a full 1.66 milliseconds shorter than average. Before 2020, Earth never experienced a day shorter than the average by much more than a millisecond. But in the past five years, it's been more likely to see days during the summer that are nearly half-a-millisecond shorter than pre-2020s levels. Days on Earth have not always been 24-hours long. Between the dinosaur-dominated Mesozoic era and the Bronze Age, days were roughly only 23 hours. Bronze Age people experienced days that were 0.47 seconds shorter than what humans in 2025 experience. Projections suggest that in 200million years, a day will extend to 25 hours. Earth may need to take a drastic measure to keep up with the new pace by introducing a 'negative leap second' in 2029, according to a study published in Nature last year. 'This is an unprecedented situation and a big deal,' study lead author and geophysicist at the Scripps Institution of Oceanography at the University of California Duncan Agnew said at the time. 'It's not a huge change in the Earth's rotation that's going to lead to some catastrophe or anything, but it is something notable. "It's yet another indication that we're in a very unusual time.'

When is the next full moon? How to see the July Buck Moon in Arizona
It's approaching that time of the month again when the moon reaches peak fullness, lighting up the night sky and giving stargazers something to howl about. This time, it's July's turn to shine with the Buck Moon, named after the time of year when male deer begin to grow their antlers. Whether you're watching from your backyard or snapping a pic for Instagram, July's full moon is a reliable cosmic showstopper, no ticket required. You just need a reasonably clear sky and maybe a little bug spray. For the biggest astronomical events of 2025, including full moons, supermoons, eclipses, meteor showers and comets, check out our celestial events guide. Here is everything to know about the full moon in July 2025. The July 2025 full moon will be on July 10. According to Time and Date, the buck moon will peak on July 10 at 1:36 p.m. Arizona time. The Buck Moon is the nickname for July's full moon, and it's named after the time of year when male deer — bucks — begin to grow their new antlers. The name comes from traditional Algonquin and other Native American naming systems. The Buck Moon typically rises in early to mid-July and often appears especially bright and golden near the horizona. The full moon in July is special for a few reasons: Culturally, it gets its name from the time of year when male deer start growing new antlers, symbolizing growth and renewal. Astronomically, it often appears larger and more golden due to summer's warm, humid atmosphere, which can enhance the moon's glow near the horizon, according to Buck Moon symbolizes growth, strength and transformation. Many believe the Buck Moon invites us to reflect on progress, set intentions and reconnect with nature. A full moon technically lasts for only a moment, the exact time when the moon is directly opposite the sun in the sky. But to the naked eye, the moon looks full for about three days: the night before, the night of and the night after its peak. The rarest type of full moon is often considered the Blue Moon, specifically the seasonal Blue Moon, which occurs about once every 2.5 to three years. Even rarer? A supermoon on Halloween, which last happened in 2020 and won't happen again until 2039. Here are the rest of the full moons for 2025: Aug. 9: Sturgeon Moon. Sept. 7: Harvest Moon. Oct. 6: Hunter's Moon. Nov. 5: Beaver Moon. Dec. 4: Cold Moon. Got a story you want to share? Reach out at Follow @tiffsario on Instagram.

Friday is the summer solstice. Sunrise to sunset, how many hours of sunlight will Georgia get?
Get ready, Georgia, the longest day of the year is almost here, and so is the official start of summer. On this day, there will be more than 14 hours of daylight. Here's everything we know. The official start of summer is Friday, June 20, marked by the summer solstice. But while the solstice signals the start of astronomical summer, the Peach State is already feeling the heat. The NWS in Atlanta issued a warning for increasingly high temperatures across the state, with heat indices expected to reach 98°F to 104°F. These elevated heat index levels increase the risk of heat-related illnesses, especially for those working or spending extended time outdoors. Residents are advised to stay hydrated, limit outdoor activities during peak heat, and check on vulnerable populations, including the elderly and young children. This Friday, June 20, the summer solstice will occur at 10:42 p.m. ET, marking the point when the sun reaches its highest position in the sky and daylight lasts the longest in the Northern Hemisphere, according to Across Georgia, there will be more than 14 hours of daylight, with the sun rising in Trenton (in the far Northwest corner) around 6:28 a.m. and not setting until 8:58 p.m. according to Time and Date. Southeast Georgia will see about 20 minutes less of sunlight Friday in places like Brunswick. When is sunrise and sunset for Brunswick, Georgia? According to Time and Date, the sunrise will be at 6:22 a.m. and the sunset will be at 8:32 p.m. This is approximately 14 hours and 10 minutes of daylight for a city along the Southeast Georgia coast. When is sunrise and sunset for Trenton, Georgia? According to Time and Date, the sunrise will be at 6:28 a.m. and the sunset will be at 8:58 p.m. This is approximately 14 hours and 30 minutes of daylight. The summer solstice marks the moment when Earth's Northern Hemisphere is tilted closest to the sun. That tilt gives us the most daylight of the entire year, along with the shortest night. According to NASA, the solstice is just a brief moment in time, but the effects last for days, ushering in the heart of the summer season. From this point on, daylight hours will slowly begin to shorten again until the winter solstice in December.
