Earth's Rotation Is Slowing Down, And It Might Explain Why We Have Oxygen.

Ever since its formation around 4.5 billion years ago, Earth's rotation been gradually slowing down, its days have gotten progressively longer as a result. Earth's slowdown not noticeable on human timescales, it's enough to work significant changes over eons. One changes is perhaps most significant of all, at least to us: lengthening days are linked to oxygenation of Earth's atmosphere, a study from 2021.

Specifically, the blue-green algae (or cyanobacteria) that emerged proliferated about 2.4 billion years ago have been able to produce more oxygen as a metabolic by-product because Earth's days grew longer. Check out the video below for a summary on the research.

Earth's Rotation Is Slowing Down, And It Might Explain Why We Have Oxygen.

An enduring question in Earth sciences has how did Earth's atmosphere get its oxygen, what factors controlled this oxygenation took place," University of Michigan explained in 2021.

Earth's Rotation Is Slowing Down, And It Might Explain Why We Have Oxygen.

Researcher suggests that rate at which Earth is spinning – in other words, its day length – may have had an important effect on the pattern and timing of "Earth's oxygenation." There are two major components to this story that, at first glance, don't seem to have a lot to do with each other. 

The first is that Earth's spin is slowing down. The reason Earth's spin is slowing down is because the Moon exerts a gravitational pull on the planet, EARTH. which causes a rotational deceleration since the Moon is gradually pulling away.

For months, silence stretched across the stars. At the edge of the solar system—more than 24 billion kilometers from Earth—NASA’s Voyager 1 probe had gone quiet, sending only incomprehensible signals into the void. But now, against all odds, Voyager 1 has come back online, astonishing engineers and reigniting hope for one of humanity’s most extraordinary scientific missions.

Oort cloud spiral is composed of billions of icy bodies surrounded by a shell of comets. Even though Oort cloud lurks at edge of our own planetary system & about 99,000 times as wide as the distance between Earth & sun, scientists have thus far been in the dark about structure of Oort cloud. Findings, however, give researchers an important clue about the object.

"Found are some comets in the inner Oort cloud found between 1,000 au to 10,000 au, form a long-lasting spiral structure," Luke Dones, study team member & principal scientist at Southwest Research Institute, told Space.com. (The measurement "au" stands for "astronomical unit," one au is equal to the distance between Earth and sun.)

Here’s what you’ll learn when you read this story: The Central Molecular Zone, spanning 700 light-years across the heart of the galaxy, contains a majority of the dense gas in the Milky Way.
While analyzing this region with the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of scientists discovered a slew of strange "slim filaments" unassociated with star-forming regions.  

The filaments are likely part of what the researchers call "space tornadoes," which distributes material throughout the CMZ efficiently. It’s been little more than half a century since scientists first proposed that a supermassive black hole lies at the heart of the Milky Way. And in the decades since, we’ve discovered a remarkable amount about our particular corner of the universe—but there’s always more to learn.

Wide-orbit planets are those circling their home star at least 100 times farther than Earth orbits the sun. These planets might not be so rare. In fact, they could be the natural result of chaotic early solar system development for stars in star clusters, said researchers. Some planets – like a hypothetical Planet 9 – could be flung out of the inner regions of the solar system but remain in the system thanks to gravity from nearby stars.

Beneath the thick ice of East Antarctica lies a hidden world—untouched for over 34 million years. This frozen expanse, more than 10 million square kilometers wide, has long concealed a forgotten landscape. Now, using cutting-edge satellite tools, researchers have pulled back the curtain on a time when Antarctica teemed with life.

Exposing the Secrets of a Hidden Land
A team led by Stewart Jamieson at Durham University made the discovery with help from RADARSAT, a Canadian satellite system. The technology allowed them to detect small changes in the ice surface, revealing the shape of the land buried below. What they found was extraordinary: an ancient river-carved terrain about the size of Wales, locked under nearly two kilometers of ice.

“It’s like uncovering a time capsule,” Jamieson said. The untouched condition of the landscape points to its extreme age. Preserved beneath the ice sheet’s crushing weight, the land remained unchanged since long before glaciation began. This hidden world dates back to a period when Antarctica was not the icy desert we know today.

Ever since its formation around 4.5 billion years ago, Earth's rotation been gradually slowing down, its days have gotten progressively longer as a result. Earth's slowdown not noticeable on human timescales, it's enough to work significant changes over eons. One changes is perhaps most significant of all, at least to us: lengthening days are linked to oxygenation of Earth's atmosphere, a study from 2021.

Specifically, the blue-green algae (or cyanobacteria) that emerged proliferated about 2.4 billion years ago have been able to produce more oxygen as a metabolic by-product because Earth's days grew longer. Check out the video below for a summary on the research.

Earth rotates on its axis, completing one spin every 23.9 hours with respect to the Sun, but 23 hours, 56 minutes, and 4 seconds with respect to distant stars. This rotation is what causes day and night, and also affects the Earth's magnetic field. The Earth's axis is tilted 23.4 degrees from the plane of its orbit around the Sun, which causes the seasons.

Here's a more detailed look:

Rotation Speed:
The Earth's rotation speed is relatively slow compared to other planets, meaning the Coriolis effect, which is a consequence of the rotation, is not strong enough to be seen at slow speeds over short distances.

Direction:
The Earth rotates eastward, in a prograde motion, meaning it spins in the same direction as the Sun's rotation. This is why the sun and stars appear to rise in the east and set in the west.

Axis Tilt:
The Earth's axis is tilted at a 23.4-degree angle relative to the plane of its orbit around the Sun. This tilt causes the seasons, as different parts of the Earth receive more direct sunlight at different times of the year.

Rotation and Day/Night:
As the Earth rotates, different parts of the planet are exposed to the Sun, creating the cycle of day and night.

Rotation & Magnetic Field:
The Earth's rotation, combined with the molten iron in the planet's core, generates a magnetic field that protects us from harmful solar radiation.

650-foot mega-tsunami sends seismic waves around world. satellites captured action.
Earth.com staff writer...Greenland’s eastern edge rarely causes a stir, yet instruments across the world lit up at the same time with a slow, steady beat that lasted nine full days pulse rose fell every ninety-two seconds – far too sluggish for people to feel strong enough to rattle bedrock from Alaska to Australia. No typical quake behaves that way.
EarthSnap: Scientists soon linked the signal to Greenland’s Dickson Fjord, a narrow inlet hemmed in by 3,000-foot cliffs. Fresh satellite images showed a new scar where a section of mountain had vanished. Something colossal had struck the water and set the fjord in motion. Mountain falls, Dickson Fjord rises. On September 16, 2023, more than 25 million cubic yards of rock and ice – enough to fill 10,000 Olympic-size pools – broke loose and plunged into Dickson Fjord. The impact hurled up a mega-tsunami wave, reaching about 650 feet high. The surge barreled down the two-mile corridor, bounced off the headland, and tore back again, wrecking roughly $200,000 in equipment at an empty research post on Ella Island. Water did not calm after the first pass. Instead, it began rocking from wall to wall, a motion known as a seiche. Computer models later showed the surface rising as much as 30 feet, then sinking the same amount in a steady rhythm that pressed on the seafloor like a giant piston.
Unusual heartbeat in the crust
Seismic stations normally record frantic scribbles during earthquakes. This time, the trace formed smooth peaks spaced a minute and a half apart and barely weakened over the better part of two weeks. No seiche had ever produced such a persistent global signature. One modeling group pegged the slosh at about 8½ feet; a second group estimated 23 to 30 feet.

The disagreement stemmed from different assumptions about the fjord’s shape, but both sets of simulations agreed on the source: the landslide-driven wave. “It was a big challenge to do an accurate computer simulation of such a long-lasting, sloshing tsunami,” said Alice Gabriel of UC San Diego’s Scripps Institution of Oceanography.
Investigators follow the clues
The mystery drew seventy-plus researchers from forty-one institutions.
“When we set out on this scientific adventure, everybody was puzzled and no one had the faintest idea what caused this signal,” said Kristian Svennevig of the Geological Survey of Denmark and Greenland. “All we knew was that it was somehow associated with the landslide. We only managed to solve this enigma through a huge interdisciplinary and international effort.”

Climate’s silent hand
Glacier ice once buttressed the failing slope, but warming air and ocean water have eaten away at that natural brace.
“Climate change is shifting what is typical on Earth, and it can set unusual events into motion,” Gabriel noted.
Similar instability elsewhere triggered a deadly tsunami in Karrat Fjord in 2017 that destroyed eleven houses and claimed four lives. Dickson Fjord sits near a popular cruise route. Though no passengers were present last year, the episode highlights rising risks as Arctic travel grows. Authorities are now reviewing early-warning options that combine satellite feeds with real-time seismic data. Satellites sharpen the picture. Conventional radar altimeters see only a thin line beneath each spacecraft. By contrast, the Surface Water and Ocean Topography (SWOT) mission launched in December 2022 maps a 30-mile-wide swath with 8-foot resolution.

“Climate change is driving the emergence of unprecedented extremes, particularly in remote regions like the Arctic, where our ability to monitor conditions using traditional physical sensors is limited,” explained Thomas Monahan of the University of Oxford.
“SWOT represents a breakthrough in our ability to study oceanic processes in areas such as fjords – places that have long posed challenges for earlier satellite technologies,” Monahan continued. Copernicus Sentinel-2 satellite image of the Dickson Fjord in East Greenland with the observed sea-surface height measurements from the SWOT satellite of the Earth-shaking wave on October 11th overlaid.

Professor Thomas Adcock, also from Oxford, remarked, “This study demonstrates how advanced satellite data can finally illuminate phenomena that have eluded us for years.”
He added, “We’re now gaining new insights into oceanic extremes like tsunamis, storm surges, and rogue waves. To fully harness the potential of these new datasets, we’ll need to push the boundaries of both machine learning and our understanding of ocean physics. Lessons from Dickson Fjord
“This shows there is stuff out there that we still don’t understand and haven’t seen before,” said Carl Ebeling of Scripps. “The essence of science is trying to answer a question we don’t know the answer to – that’s why this was so exciting to work on.” Every new discovery will refine models of how slope failure, fjord geometry, and water depth interact. Better forecasts could one day provide critical minutes of warning for ships and settlements in high-latitude waters – proof that even the quietest corners of the planet deserve a closer listen.
