While scanning the interior of Earth using neutrinos, a team of scientists from Spain also used these subatomic particles to measure the mass of Earth. Their result is in agreement with the current best estimate, which was measured using the value of the gravitational constant (G).
A lazy buzz phrase – ‘Is this the new normal?’ – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it’s worse than that – we’re on the road to even more frequent, more extreme events than we saw this year.
We have known since the 1980s what’s in store for us. Action taken then to reduce emissions by 20
The chart below compares some wild animals’ claws (including the Siberian tiger, African lion, Jaguar, Cougar, Grizzly bear, Harpy eagle, and Polar bear).
Even we could remove the effects of the moonlight, starlight and diffused sunlight from the far side, the Earth’s night sky would never be totally dark. This phenomenon is known as Airglow (also called nightglow). Airglow is a faint emission of light by Earth’s atmosphere (or any planetary atmosphere).
One of the most surprising facts about the Earth is how we easily forget that what an amazing and interesting planet we live on. As Carl Sagan pointed out, “It’s home, it’s us”. It is the only known planet to support an atmosphere with free oxygen, liquid water on the surface, and, perhaps this is the most important amazing, life. Here are 50 interesting facts about Earth.
Mount Etna, Europe’s most active volcano (also one of the most active volcanoes in the world) is sliding into the Ionian Sea at rates of centimeters per year. If part of it falls into the sea, it could create horrible mega-tsunamis that would devastate the eastern Mediterranean shores.
In the middle of the South Pacific Ocean, there’s a location called “Point Nemo”. It’s not a place where humans live, in fact, there is no land there: not an island, not even a small rock. It is actually the remotest place from any human civilization you can find on Earth. It lies at least 2,688 km (1,670 mi) from the nearest land. It is also called the “Oceanic Pole of Inaccessibility” (see notes 1).
Back in December 1990, during its flyby of Earth, NASA’s Galileo spacecraft, which studied the planet Jupiter and its moons, as well as several other Solar System bodies, pointed its instruments towards Earth, at the urging of Carl Sagan. And, it has found evidence of life on our planet. This can be a key to detecting vegetation on exoplanets – which is key to a possible i
In a paper published in Nature, researchers wrote “The Galileo spacecraft found evidence of abundant gaseous oxygen, a widely distributed surface pigment with a sharp absorption edge in the red part of the visible spectrum, and atmospheric methane in extreme thermodynamic disequilibrium. Together, these are strongly suggestive of life on Earth.”
The universe is shrouded in mystery, and part of this mystery involves our own little planet. Although there
However, the studies in Seismology have allowed us to gather sufficient information about the Earth and its structure. The planet comprises several layers, which have their own attributes, and composition. So let’s dive in further to discover some enlightening aspects.
Earth, our beautiful blue planet. It is the third planet from the Sun, but above all, it is our home, the only astronomical object known to harbor life. Here are the top 10 best Earth quotes.
