How do you understand the natural history of rocks and water on another planet when all you have are pictures? You do the math. Scientists have discovered how to use images of pebble shapes to estimate to estimate how far water may have moved them in ancient Martian riverbeds. These estimates enhance geographic information about […]
Just as the Moon is causing waters on Earth to go up and down (tides), so too does the Earth affect the Moon. Recently, researchers have found that our planet's gravitational pull is having a deep effect on our satellite, opening new cracks and faults on its surface.
NASA's New Horizons shuttle wasn't only taking mind blowing photos of Pluto, it was also peeking at Pluto's moons, especially Charon - the largest one. The latest set of images analyzed by NASA researchers revealed quite a busy past, filled with violence and geologic activity.
Paleontologists believe they have found the oldest evidence of the bubonic plague, embedded in a flea trapped in amber for the past 20 million years. This could provide insight onto how this devastating disease appeared and evolved.
Enamel, the hard, mineralized substance that covers your teeth originated on tough fish scales and then migrated to the teeth, researchers found
Specialists from the University of Cambridge and the University of Colorado estimate that the effects of climate change are going to take a hefty toll on our economy -- $326 trillion in damage by the year 2200, roughly $201 million each hour, the Christian Science Monitor reports.
Trilobites were some of the most dominant creatures on the face of the planet, thriving from the mid Cambrian 521 million years ago to the start of the Mesozoic, 250 million years ago. Paleontologists have now found the earliest evidence for molting - a trilobite shedding its skin 365 million years ago.
About 260 million years ago, this pre-reptile might not have looked like much. With its knobby face and about as big as a cow, Bunostegos akokanensis was actually pretty remarkable. According to a new analysis, it was actually the first creature to walk upright on all four legs, maintaining a fully erect gate.
Scientists have discovered the longest chain of continental volcanoes in the world, stretching almost 2000 km (1200 miles) on Australia's coast. The volcanic track includes 15 volcanoes formed over 30 million years ago.
A massive 8.3 magnitude Earthquake struck the northern coast of Chile on Wednesday night, killing at least five people and causing buildings to sway in the capital city of Santiago. Following the earthquake, waves of up to 4.5 meters were reported in some areas of the coast. About one million people were evacuated.
NASA recently uploaded a strikingly beautiful photograph on their website showing a petrified sand dune on Mars. The image was actually pieced together from several shots taken using Curiosity's Mast Camera (Mastcam) on August 27th. From end to end, the panorama spans a full 135 degrees of other-worldly awesomeness, with east to the left and southwest to the right.
An ocean of magma could explain why Jupiter's moon Io has volcanoes in the "wrong place". This would also mean that Io has an ocean of liquid water beneath its surface and might be potentially habitable.
An isolated bay in the heart of East Africa offers scientists a glimpse into early Earth's iron-rich marine environment, and lends weight to the theory that microbial activity created some of the largest iron ore deposits billions of years ago.
Scientists from the Smithsonian have a surprising fossil dating about 6 million years old. The fossil seems to have been an ancestor of modern dolphins and might explain why dolphins left rivers and set out for the ocean. Today, there are almost 40 species of dolphins, and all of them are intriguing animals. For starters, […]
We tend to think of flowering plants and ubiquitous, but in truth, they’ve “only” been around for about 125 million years – which geologically speaking… is still a lot, it’s just not forever. Geologists may have just found the oldest flower. Looking through some previously discovered fossils, scientists were thrilled to find a spectacular specimen: […]
Finding insects, plants or even dinosaur feathers trapped in amber s rare and exciting. But finding a fossil salamander in amber… that’s something else – it’s actually unique. But the salamander’s unfortunate fate sparked immediate interest from researchers: not only is it a unique finding, but it’s from a never-before seen species of salamander, and […]
Paleontologists have discovered a set of dinosaur footprints that seem to indicate social behavior in carnivorous dinosaurs. The footprints, found in northern Germany, belonged to two dinosaurs, one larger, and one smaller.
Hydro-energy is clean, cheap and reliable – in many ways, it’s every man’s dream: you get the reliability of fossil fuels with the eco-friendliness of wind and solar. But hydro also comes at a price, one that we are only recently discovering: it threatens biodiversity and encourages erosion. The removal of a dam on the Elwha […]
As a geologist, I'm not into gemstones and "pretty rocks" - but every once in a while, I see a rock so spectacular that it just blows my mind. Such is the case with "Virgin Rainbow", a glorious opal unveiled by the South Australian Museum in Adelaide.
Scientists analyzing data from the Large Binocular Telescope Observatory in Arizona spotted a huge lava lake on Io, one of Jupiter’s largest moons. We’ve known for a while that Io is quite an amazing (and hellish) place; it’s the most geologically active place in the solar system, with extreme geologic activity occurring as a result of tidal […]
Mars is now a cold and dry place, but it wasn't always like this - the Red Planet used to have a lot of water on its surface. Now, researchers have discovered one of the very last places where (potentially habitable) liquid water existed on Mars.
Before the Cambrian, more than 541 million years ago, intriguing creatures named rangeomorphs that grew up to 2 meters dwelt in marine environments. They were unable to move, had no apparent reproductive organs and there is no evidence of them having a gut or a mouth. But a new study has found that their reproductive techniques […]
Fossils of an elasmosaur, a rare type of plesiosaur were discovered in Alaska by Anchorage-based fossil collector Curvin Metzler. Researchers have confirmed this discovery and identified the species.
An "absolutely exquisite" fossil of a juvenile snake with limbs has been discovered by English paleontologists in Brazil. The fossil dates back from the early Cretaceous, 110 million years ago, and is the oldest evidence of a definitive snake.
Researchers have discovered a new dinosaur species covered with feathers. Its wings were very short and it likely wouldn't have been able to fly or glide, but the creature was on the cusp of evolving into a bird. It was also one of the ancestors of the velociraptors.
Scientists have stumbled on some incredibly old sperm in the wall of a fossilized cocoon in Antarctica. The remains of the long, thin cells represent the oldest animal sperm known to man - 50 million years old.
A chance discovery revealed an impressive cluster of extinct volcanoes 150 miles off the coast of Sydney, three miles below the water surface. The four volcanoes, which are now calderas, may reveal why Australia and New Zealand separated between 40 and 80 million years ago. Don’t you just hate it when you go searching for lobsters […]
Paleontologists have discovered what looks like the earliest member of the Corytophanidae (also known as casquehead or helmeted lizards) judging from fossils collected in Wyoming. The ancient species is also the earliest ancestor of the modern basilisk, or better known as the Jesus Lizard because of its ability to skim the surface of water over short distances.
Rosetta is a robotic space probe built and launched by the European Space Agency. Along with Philae, its lander module, the craft is performing a detailed study of comet 67P/Churyumov–Gerasimenko. The probe usually orbits 67P at a distance of a few hundred kilometers. Footage received from Rosetta over the last year showed a number of dust […]
Saber-tooth cats, the bane of early humans (and pretty much every creature that co-existed with them), roamed the Earth for 42 million years before going extinct at the end of the ice age. Now, a new study has found that their trademark teeth may have evolved later in their evolutionary stage, but when they grew, they grew […]
Paleontologists working in China have discovered fossils of an impressively armored worm that lived during the Cambrian, 500 million years ago. Called Hairy Collins’ Monster, this is one of the first creatures to develop a spiky armor. Today, the 180 species of velvet worms are pretty similar – they have tiny eyes, antennae, multiple pairs of […]
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.
