If there are any, aliens should be less conspicuous and charismatic-looking than most people think.
It's not exactly accurate, but it's a dazzling display.
This planet is restless to its core.
The ebb of 20 years worth of seasons condensed in 2.5 minutes.
Each of the two belts surrounds the Earth in a sort of doughnut-shaped formation.
Early Earth could have lost as much as 40% of its mass during collisional growth.
Bird's eye view.
Not all planets are as lucky as Earth.
We are legion!
Talk about hailstone, right?
Who wouldn't?
Worry and excitement, all in one paper.
There's no proof. But the conditions were right for it to happen.
Our humble satellite just got a heck of a lot more interesting.
Tick tock.
Silly bacteria, carbon-based life is best life!
It doesn't answer everything -- but it's a good point to start from.
An ancient oceanic slab buried beneath the Mediterranean sea might revise textbooks.
We use so much of everything so fast that it's literally killing the planet.
The swirling gases could shed light on the atmosphere of other planets within and outside of our solar system.
The new findings call our current theories on the mass extinction event into question.
Despite being thousands of kilometers away, the sun and moon are behind some of the earthquakes on the Earth.
Death from the heavens.
These movements could in turn help speed up global warming.
Crash boom bang! Our planet and another protoplanet may have collided head-on in their early history.
Scientists finally crack down a puzzle that has eluded the community for years. It seems sea level rise does indeed slow down Earth's spin.
Astronomers describe that the present-day tilt of the Moon is likely a result of collision-free encounters of the early Moon with small planetary bodies.
Gas giants like Saturn or Jupiter may have formed not from a planetary core, but rather from tiny pebbles that stuck together. This theory would solve one of the biggest problems about our understanding of planetary formation: the timeline. The previous model was called core accretion: you have a planetary core of rock and ice that […]
Using three state of the art ground-based telescopes, a team of astronomers has identified three super-Earth exoplanets that are seven to eight times as massive as our own planet and orbit their parent star closer than Mercury orbits the sun. What's hot about the findings - apart from the planet's likely scorching surface - is that these were made using a novel automated approach, in which one telescope called the Automated Planet Finder (APF) Telescope at Lick Observatory in California was programmed to scour the night's sky and look for signs of nearby alien planets. These three planets are just the beginning of a new process that hopefully will return hundreds of planets in our neighborhood, all without the need for human supervision.
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.
A new shocking theory suggests that Jupiter may have sweeped through our solar system much like a wrecking ball, knocking planets out of the solar system our moving them outwards, to the position we see them in today. If this is true, then it might explain why our solar system is a rarity and why life emerged the way it did.
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.
Because the moon is tidally-locked to Earth, we’re used to seeing our cosmic neighbor like a stationary lonesome figure. Now, NASA released an animated simulation of the moon’s phase from its so-called dark side, offering an insightful glimpse from the other side of the coin. Far side of the moon – not so dark after […]
Many thousands of miles above our planet’s surface, electrons whiz through close to the speed of light. These electrons can streak past Earth in under five minutes, but can also become dangerous and have been known to destroy satellites and even injure astronauts in extreme cases. Most of the time, however, our gear and astronauts can rest […]
Scientists have indirectly demonstrated the existence of a hot layer surrounding the Moon's core, through seismic and deformation studies. This layer is created by the gravity exerted by the Earth on the Moon and can provide valuable information regarding the evolution of the Earth-Moon system.
Over the past six months, the Earth’s magnetic field – the bubble that protects our planet from incoming radiation and solar winds – has weakened by a factor of ten than what’s been registered in previous years. According to the European Space Agency (ESA), this discrepancy might indicate that the magnetic field is about to flip. […]
A new massive computer model that simulates the formation of the solar system from its early days when all it used to comprise was a huge disk of matter to present day shows that Earth’s moon formed some 65 million years later than previous estimates led us to believe. The method provides a new way […]
Using two different dating technique, geologists have come across what they believe to be the oldest piece of Earth discovered thus far. The zircon crystal, found on a sheep ranch in Western Australia , was confirmed to be 4.4 billion years old and offers tantalizing clues and insights on how our planet must have looked like in […]
The discovery of a giant planet orbiting its star at 650 times the average Earth-Sun distance baffled researchers. So far, they haven’t been able to explain how such a strange system came to be. The international team of astronomers was led by a University of Arizona graduate student. This is the most distant planet ever […]
Billions of years ago, the Earth was unrecognizable from the life supporting paradise it is today. Fossilized raindrops from some 2.7 billion years ago, conserved in time as rain dropped onto volcanic ash during an eruption, which eventually solidified into rock known as tuff, has revealed some very interesting facts about Earth’s ancient atmosphere. The discovery […]
Eris is a dwarf planet, observed in 2005 for the first time, whose discovery led to Pluto losing its planet status, even though a new moon was found orbiting it; recently, Eris passed in front of a planet, giving astrophysicists a clear view for the first time. Until now, the general scientific idea regarding it […]
Uranus, the seventh planet from the sun, is a definite oddball of the solar system. It has its axis titled by a whopping 98 degrees, which makes it orbit on its side. The general accepted theory is that a big impact with an object several times the size that of the Earth nodged its axis […]
How’s your Mandarin? If it’s as rusty as mine, we’d do best and brush up on it since it seems we’re heading towards an age of Chinese domination. Capitalizing on its tremendous financial growth, China has some incredible programs which officials hope to catapult the people’s republic in front of the new space age. A […]
Astronomers from the the Armagh Observatory in Northern Ireland declared that a recently discovered asteroid has been following our planet in the past 250.000 years, and it may be in fact closely related to Earth. Two months after it was discovered with the WISE survey satellite, the asteroid caught the attention of two scientists: Apostolos […]
Contrary to what you might expect, a recent published study unveiled by scientists shows a map of our planet’s gravity, which resembles not a sphere, but more a … potato. This is because the Earth’s gravity isn’t uniform, being affected everyday by such factors like winds, currents and tides, so because gravity is higher in […]
The Planet Researchers have long been interested in finding other planets that have approximately the same size as our mother earth, because it’s estimated that they have the biggest odds of hosting life in a significant diversity. However, out of the over 400 planets that have been discovered so far, the vast majority resembles Jupiter […]
Scientists have for the first time determined the actual permeability of the asthenosphere in Earth’s upper mantle, which is basically responsible for how fast the melt rises towards the surface of the earth, and the results were surprising to say the least. Researchers found that it actually moves 25 times faster than previously assumed, which […]
We’ve all seen at least one movie in which our planet is destroyed, but most of them were quite repetitive and kind of uninteresting. Our planet deserves so much more! Black holes Well, it seems the more we understand things about black holes, the more we find out things we don’t know, and the more […]
Earth Hour is an initiative started by the WWF (World Wide Fund for Nature/World Wildlife Fund) that asks people everywhere in the world to turn off the light and other unnecessary household appliances for one hour, to raise awareness towards the need to tackle global warming and other environmental problems. The “grandfather” was an idea […]
A very small asteroid exploded over the continent of Africa this week, confirming the prediction of astronomers. Despite the fact that nobody has seen and photographed the asteroid due to the fact that it entered in a very remote area, it was detected with an infrasound array in Kenya; it exploded without striking the Earth.
