Mars has over 250,000 craters created by asteroid impacts, the Moon has millions - too many to count. But the Earth has an atmosphere, which means we're protected against most threats and we have much to be thankful for. But even the craters that we do have are constantly eroded by wind and water, so finding and identifying them is quite a challenge.
Researchers from the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) have been trying to figure out how Titan's seas formed - more exactly, how the depressions in which the seas are formed.
Sampling impact glass from the ancient craters that litter the surface for Mars might prove key to settling a long debate: did Mars ever harbor life? Researchers at NASA believe this is a great lead after the Mars Reconnaissance Orbiter (MRO) currently hovering above the red planet found deposits of glass. These were formed by impacts with large asteroids, whose blast trapped and preserved any matter it came across: dust, soil or any plants or bacteria (if there ever were such things). Cracking open these glass time capsules and peering inside could, thus, be one of the best places to look for.
The Houston Museum of Natural Science is one of the most impressive in the world, curating rare and indigenous wildlife from Texas, a huge sundial and one of the biggest paleontology halls. As expected in a city with some of the richest geologists in the world, we can also find here a large exhibit of over 750 crystallized mineral specimens and rare gemstones. Among these sits the "crown jewel", a 1,869-carat natural emerald crystal, the largest ever discovered in North America.
It's not just the San Andreas fault - a new study published in the Journal of Geophysical Research reports that there are several long faults on the U.S. West coast which can cause significant earthquakes, as well as tsunamis.
New controversial research concluded that dinosaurs weren't the cold blooded lizards we tend to see them today - instead, they had much in common with mammals, and were warm blooded.
An Alberta citizen discovered a trove of rare fossilized fish while digging up his basement. But Edgar Nernberg isn't a man who "believes" in science - instead, he claims that the fish are 4,500 years old, from Noah's flood.
We tend to think of the planets as static, enduring, and never changing. With the average human life spanning only decades, we can be forgiven that the dimension of time in which geological processes take place goes a bit over our heads. However, recent images captured by satellites showing the birth of two volcanic islands published in a study by Nature Communications are a powerful reminder that the Earth is a planet alive under its crust as well as above.
This Monday morning, a volcano perched on one of Ecuador's Galapagos islands erupted spewing lava on its side and dark plume overhead. The Wolf shiled volcano is the highest peak in the Galapagos Islands, reaching 1,707 m. Wolf is situated at the northern end of Isabela Island in the Galapagos, which is barely populated. The authorities have indeed confirmed that the population isn't at risk, however the local, richly diverse fauna is another thing. The tiny island is the only place in the world that the pink iguana calls home.
Geologists are expecting increased activity on the Kilauea volcano, warning that another eruption is likely possible. It seems that lava continues to build up, as manifested through a swarm of minor earthquakes.
Researchers from the University of Pennsylvania have discovered a new species of dinosaur, closely related to the famous velociraptor. This new species, Saurornitholestes sullivani was a bit bulkier, probably had a better sense of smell, an researchers believe it was an even better predator than its cousin.
Every year, in Oregon, a mysterious lake fills up with snow melt, and then every year it disappears; it’s a natural wonder that had many scientists puzzled as to where the water is going, but now, the mystery is out: the water appears to go into a lava tube. They call it the Lost […]
Megafloods likely wiped out one of the most significant American civilizations, a new study has concluded. Until now, the reason of their demise remained a mystery.
A crater wall collapse in a Hawaiian volcano has triggered a powerful lava explosion. The Kilauea explosion spread lava and debris around it, in a spectacular display which was caught on camera by the USGS. Material was thrown 280 feet (85 meters) up into the air. Janet Babb, a geologist with the USGS, compared the […]
While fjords are admired worldwide for their unique beauty, a new study has found that these natural ecosystems also act as carbon sinks, playing an important role in regulating our planet's climate.
An underwater volcano 300 miles off the coast of Oregon has awakened from its slumber and apears to spew out lava. There is no immediate danger, but geologists are excited to be able to study it in real time.
Geologists have found a praying-mantis-like cockroach that lived at the side by side with the dinosaurs, 100 million years ago, during the mid Cretaceous. The insect was preserved in amber. Peter Vršanský from the Geological Institute in Bratislava, Slovakia, and Günter Bechly from the State Museum of Natural History in Stuttgart found the insect at a mine in […]
A seven year old has discovered the fossil of a turkey-sized dinosaur that roamed South America over 140 million years ago. The tiny dinosaur was related to T-Rex, but had few similarities to it; aside for its size, the dinosaur was a vegetarian, munching on plants instead of terrorizing other creatures.
Beneath one of the most famous touristic attractions in the world, the Yellowstone National Park, there lies one of the largest and most complex volcanic systems in the world. Yellowstone is a supervolcano of perplexing size, but as Utah seismologists found... it may actually be even bigger than previously thought.
There's so much you can do with a smartphone today - much more than just browsing the web or social media. When you can combine them in a network, however, the possibilities might be endless. For instance, researchers at Caltech and the United States Geological Survey (USGS) are working on an earthquake early warning system based on the collective data fed in by thousands of smartphones. Only a couple of countries in the world give vulnerable cities an early warning - often just enough time to hit cover and save your life - but smartphones are virtually ubiquitous all over the world, even in poor countries which lack basic infrastructure like roads or flushing toilets.
Astronomers have known for quite a while that Mars has distinct polar ice caps, but the Red Planet might also have belts of glaciers at its central latitudes in both the southern and northern hemispheres. These huge glaciers are covered by a thick layer of dust which masks them and makes them seem like they are actually part of the surface of the ground.
When tyrannosaurs ruled the world, no one was safe from them - not even other tyrannosaurs. The skull of an unfortunate adolescent tyrannosaur shows signs of brutal fight; the individual was defeated and then eaten by members of its own species, new research shows.
Most people tend to think of the Earth in terms of crust, mantle and core, and while those are indeed the largest "layers" (you can't properly call the mantle a layer though), each one of them is made from other, thinner layers. Now, researchers from the University of Utah have identified another one of these thinner layers, 930 miles beneath our feet.
Paleontologists have found the remains of a "super salamander" - a previously unknown car-sized species of early amphibian. The predatory salamander likely feasted on fish and even small dinosaurs.
Australian researchers have uncovered what might be the biggest impact asteroid impact zone in the world – at over 400 kilometers (250 miles)! Naturally, the crater isn’t visible today, but geophysicists have found the impact’s scars deep below the surface. Lead researcher Dr Andrew Glikson from the ANU School of Archaeology and Anthropology explains: “The two asteroids […]
Even as a geologist, I can’t help myself from looking at lava with an almost childish fascination — it’s something from the depths of the Earth (literally), with the potential to destroy anything in its path, and also to create new landscapes, drastically changing the surface of the Earth. In the short film above, Lance Page managed […]
Some 17 million years ago, a beaked whale took a wrong turn up an African river, something which ultimately proved to be its demise. But now, geologists studying the whale's fossils believe the whale's unfortunate end might shed a new light on early human evolution.
Some 480 million years ago the seven-foot-long Aegirocassis benmoulae swam in a shallow sea covering what is today the Sahara desert. This giant arthropod, much larger than arthropods existing today, was likely the biggest creature in the world at the time.
The Moon's geologic past was much more interesting and active than previously thought, results from the Chinese lunar rover indicate. The Yutu moon rover found evidence of at least nine distinct rock layers deep beneath its wheels, something which seems to indicate a more complex setting.
Deep inside the Earth, in the gigantic Hang Son Doong cave in Vietnam, there lies a completely unique and mostly unknown ecosystem. Using a GoPro-carrying drone, Beijing-based traveler Ryan Deboodt provides a unique insight into this cave, showing a pristine, forgotten world. The cave was only discovered in 1991, but even then, scientists had to wait until 2009 […]
If you've ever visited the McMurdo Dry Valleys in Antarctica, then you've likely had a surprise. The cold, frigid white background cut by snowless valleys is marked by the Onyx river, the continent's longest and largest river, which ends with a five-storey-tall waterfall that spills bright blood-red water over an enormous glacier.
An eruption from an underwater volcano in the Pacific 'Ring of Fire' caused a 1-km wide island to form.
The Sahara Desert and the Amazon area have few things in common - one is a dry, barren wasteland, while the other is the most fertile area on Earth. But according to a new NASA study, there may be more than meets the eye when it comes to the two - dust from the Saharan area makes the trans-Atlantic journey, fertilizing the Amazonian rainforest with phosphorus.
A magnitude 6.8 earthquake (initially 6.9) has struck Northern Japan earlier today, with a small tsunami striking the coast without any significant damage. The tsunami was on the order of tens of centimeters. There was some worry, despite Japan being one of the most well prepared countries in the world to deal with earthquakes. “Overall, the […]
Billions of years ago, our ancient planet collided with a Mars-sized object called Theia. The impact released tremendous amounts of energy which is thought to have produced a whole mantle magma ocean, which should have erased pre-existing chemical heterogeneities within the Earth. Following the onslaught, a new Earth formed, along with the moon. New geochemical findings hint that the impact didn't completely melt the whole planet, leaving clumps and patches intact. This ancient past is thought to still ripple in Earth's mantle.
We tend to think of pollution as a modern thing; after all, industrial pollution should be, well… industrial, right? Well, not quite: a group of researchers found 400 year old traces of pollution in the Peruvian Andes. The pollution was caused when the conquistadors forced the Inca to mine silver from “mountaintop mines”. Ancient Pollution […]
It’s hard to think that the crust’s thickness (which varies between several and several tens of km) can be affected by what happens on the surface – but that’s exactly the conclusion of a recent study conducted by British researchers. They found that during an ice age, when sea levels are low, the magma that spreads […]
An underwater volcano that’s been spewing ash and lava for the past month just created a new island off the Tonga archipelago. The volcano, called Hunga Tonga, has since stopped erupting and the island might not be long lived. Mostly made of ash and formed around the crater of the volcano, the half-mile long island […]
According to a new study, water once flowed on the surface of Vesta, the second-largest asteroid in the solar system. This took astronomers by surprise, as no one was really expecting to find this.
Some fires are big enough to see from outer space, others burn for a very long time, but from what I could find, this is the oldest continuous fire in the world. Beneath an Australian mountain, a fire has been burning continuously since 4000 BC.
Aboriginals around what is today Melbourne have been telling a story for thousands of generations – a tale of waters rising after the ice age. Without using written languages, they passed it down orally, generation to generation, with surprising accuracy. Now, a new study concluded that the story is actually really accurate, despite being passed […]
The Permian was a geologic period that ended some 250 million years ago, with the largest extinction our planet has known. Geologists have now found evidence that global acidic rain accentuated or even caused the massive extinction.
A new study may have finally found where Earth’s water came from. There are currently two competing theories, with one claiming that our planet generated its own water geologically, while the other suggests that water was brought by icy comets or asteroids from outside. A new study concluded that most of the water we see […]
Hydraulic fracking is responsible for a swarm of earthquakes, one of which was felt by Ohio residents in March 2014, a study has found. While the earthquake hag a magnitude of only 3.0 degrees, it is believed that it may have activated a geological fault and may ultimately lead to more significant temblors.
A giant reptile which looked somewhat like a dolphin but had the behavior of a dinosaur was discovered around what is now the Isle of Skye, in Scotland. The predator, an Ichtyosaur lived 170 million years ago and its diet probably consisted of fish and invertebrates, but it may have also eaten sharks and even dinosaurs.
In March 2014, the US and Mexican governments decided to release a flow of water down the Colorado River, in an experimental attempt called “Minute 319”. The river has experienced record droughts in 2014, but surprisingly, this initiative reversed a 13-year decline in the greenness along the delta. The Colorado River stretches along 1,450-miles (2,330 km), encompassing seven […]
Do you fancy diamonds? If the answer is ‘yes’, then you’ll absolutely love this rock extracted from a Russian mine. The rock is littered with over 30,000 diamonds, something which is extremely rare and may yield valuable information about how diamonds form in natural conditions. What’s unlucky for gem sellers was very fortunate for researchers […]
If you have a geologist friend or family, then you probably know they’re an awesomely weird bunch. I’m a geologist myself, and even I find it hard to buy presents for another geologist sometimes – so this is why I put along this list – to give you an idea of some awesome stuff you […]
A rare 520-million-year-old fossil shaped like a ‘squashed bird’s nest’ has been discovered by a Chinese team of paleontologists. The team believes that the fossil, which is in excellent shape, will help us better understand how the Earth’s seas were like during the Cambrian.The fossil probably belongs to the ‘chancelloriid’, a group of bizarre, balloon-shaped creatures […]
New experimental research found that Saturn’s largest Moon, Titan, has much stronger winds than previously believed. These rogue winds actually shape the hydrocarbon dunes observed on its surface. Titan is, along with Earth, one of the few places in the solar system known to have fields of wind-blown dunes on its surface. The only other ones […]
