adventurer have scale the major planet ’s highest peak and trawl its deepest ocean deep , yet Earth is still pour with arcanum waiting to be discovered .
Every year , scientists knap off at the enigma obliterate in the third rock from the sun , and this year was no exclusion . From a concealed mesh of under - ice river in Antarctica to upset new findings about the San Andreas Fault , here are some of the most surprising secrets we learned about our home satellite in 2022 .
Our planet revealed some amazing secrets in 2022.
1. An under-ice Antarctic river 300 miles long
This year , scientists see ariver coursing beneath the Antarctic ice sheetthat was as long as the River Thames in England . Scientists found the subterraneous thoroughfare , which drains a part as giving as Germany and France combined , by using ground - penetrating radio detection and ranging .
The discovery of this veil meltwater drainage system could be the " wanting link " that explains where and how Antarctica ’s ice is thaw , scientists said .
2. Dino-killing asteroid caused months-long quakes
The asteroid that wiped out the non - avian dinosaur 66 million days ago triggeredmonths farseeing quakes that rocked the planet , new enquiry revealed . grounds of the mega - quake was revealed in rock and roll around the Chicxulub impact crater in Mexico .
Yet some of the misrepresented and rumpled layer of rock from this ruinous crash contained traces of pollen — grounds that life get to rebound as little as six month after the impact .
3. Massive solar storm 10 times bigger than the Carrington Event revealed
Amassive solar tempest large than the Carrington Event , has been disclose in routine of ancient rocks . tincture of radioactive versions of beryllium , atomic number 17 and carbon in sway from Greenland unwrap that a monolithic proton storm slam into Earth ’s magnetosphere in 660 B.C. , or 2,600 years ago . Further evidence intimate large proton storms may have collide with three meter in the last few millennia .
The previously unidentified tempest occur before electrical energy , satellites and telecommunications , but if a similarly strong storm were to hit now , the impairment could be tremendous , researchers say .
4. Mantle blobs fuel a diamond factory near Earth’s core
Two giant blobs of tilt under Africa and the Pacific may be driving the production of diamondsat the boundary between Earth ’s sum and its drapery — its middle level — researchers found .
Where the gist meets the mantle , smooth smoothing iron meets solid rock ‘n’ roll at utmost temperature and pressures . preceding research suggested these utmost condition , combined with water locked in mantle rock candy , can fire chemical synthesis , such as diamond establishment .
To quiz this idea , the researchers put together the chemicals typically found at the Congress of Racial Equality - mantle limit and subject them to crushing pressures under a diamond anvil . They produced petite rhomb , suggesting that the blobs in the mantle , also called ultra - scurvy velocity zone , may be places where water drives melt and thereby fuel adamant formation .

5. A 4 billion-year-old chunk of Earth’s crust found
scientist found a4 - billion - twelvemonth - old hunk of Earth ’s incrustation hiding out in Western Australia . The obscure rock was found not far from where Earth ’s oldest minerals were find in Australia ’s Jack Hills .
The ancient rock sweep a region about 38,610 straight Admiralty mile ( 100,000 straight kilometers ) in area . Crust of about the same eld can be regain around the world , suggesting that some changeover occur on Earth around that time , the researchers order .
6. Most powerful lightning bolt ever detected
Agigantic squirt that shot into space may have been the most powerful lightning bolt ever detected , researchers say . The jet plane first pinged detectors above a cloud in Oklahoma in 2018 . Now , scientists have finally analyzed the jet ’s radio wave emissions using radar and satellite data . The jet jolted a huge amount of energy into the ionosphere , the layer of institutionalize subatomic particle that separates Earth ’s upper atmosphere from empty outer space . The bolt produced 60 times as much energy as a typical lightning bolt , the study found .
7. City of towering hydrothermal vents discovered deep beneath the ocean
Scientists pilot a remotely operate vehicle a few hundred miles off Mexico chance on amassive region of towering hydrothermal ventson the seafloor 1.5 mi ( 2.5 klick ) beneath the Earth’s surface of the Pacific Ocean .
The massive vents , which are up to 40 feet ( 12 metre ) marvellous and look like candelabras , rave out mineral - fertile body of water that belike depart at a blacken 818 degrees Fahrenheit ( 437 academic degree Celsius ) .

The dinosaur-killing Chicxulub impact triggered a months-long mega-earthquake that left its mark in the rock.
8. Ancient source of oxygen for early life unearthed
scientist have discovered anancient source of oxygenthat could have fueled the rise of early life on Earth . Powerful seism struck the planet roughly 3.8 billion old age ago , cracking it like an orchis . The combining of near - boil water and seismic action could have generated the oxygen needed for some of Earth ’s earliest lifeforms .
The oxygen would have come packaged as atomic number 1 peroxide , which is toxic to living but could nevertheless have been harnessed by transmissible lifeforms standardized to extremophiles and archaea . These ancient sprightliness forms would have expand in the blistering temperatures of early oceans , and could have visualise out ways to detoxify the hydrogen peroxide to rein in its O , researcher suggested . This source of oxygen would have predatedphotosynthesis , the current dominant source of the satellite ’s oxygen , by up to afew hundred million yr .
9. Mountain-size rock under Japan channels quakes
Amountain - size of it rock veil under Japan may be channeling earthquakesin the region . The igneous rock , dubbed the Kumano Pluton , is a few miles beneath the encrustation of the Eurasian continental plate under the Kii peninsula . In this part , the Philippine photographic plate is diving beneath the Eurasiatic photographic plate , and the pluton may be changing the slant of that prima donna .
Two major earthquake strike in the 1940s , but did not join up , and the pluton may be a full-grown reason , researchers discovered .
10. Oldest evidence of plate tectonics unearthed
Scientists haveunearthed the oldest grounds of plate plate tectonics , in minuscule crystals from South Africa . Each crystal is no bigger than a grain of sand , and they show that the Earth ’s freshness broke up and began to move around 3.8 billion years ago .
These crust movements may not have been full - fledgedplate tectonics , the modern outgrowth by which Earth ’s freshness is continually recycled into its interior . But a primitive impertinence conveyor belt was likely already churning then . This plate motion occurred relatively soon after the crust formed , around 4.1 billion years ago , researchers said .
11. Middle of the San Andreas fault could unleash large earthquakes
The creeping"middle " section of the San Andreas flaw could unleash temblor of bigger order of magnitude than previously imagine . retiring work suggested the San Andreas fault in this realm , between Parkfield and Hollister , could generate no liberal than magnitude-6.0 seism . But earthquake generating more than 10 time the energy — neat than order of magnitude 7.0 — have struck this fault region in the last few million years , the study authors obtain .
A gigantic solar storm hit Earth about 2,600 years ago.

Researchers surveyed hydrothermal vents in the Pacific using temperature loggers manufactured by EP Oceanographic. The loggers collect data every ten minutes, in order to track changes in vent fluid temperature that can be used to infer changes in permeability of the crust beneath the vent.

The mountain-sized chunk of rock is nestled in the crust of the continental Eurasian plate, under which the oceanic Philippine plate is taking a dive toward the Earth’s mantle.
