The third planet in the solar system

Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.
A Ph.D. student at the University of Alberta has discovered a new and curious mineral inside a diamond unearthed from a mine in South Africa.
Ancient, distinct, continent-sized regions of rocks, isolated since before the collision that created the Moon 4.5 billion years ago, exist hundreds of miles below the Earth's crust, offering a window into the building blocks of our planet, according to new research.
A pair of scientists, through their research paper published last month, explained a method of constructing a 322,000 kilometers-long cable elevator that is anchored to the Moon.
A huge dust cloud swept across the solar system sparked an explosion in primitive life on the Earth. The dust got created after a huge asteroid got smashed into pieces after a collision somewhere in between Mars and Jupiter, scientists said.

Nearly half a billion years ago, there was a huge explosion of species development on Earth, causing the biodiversity of animals to increase dramatically -- but the true cause of that event has remained a mystery.
During the Eocene era, Earth's atmosphere had much more CO2. Understanding the effects of that could improve models of climate change.
Scientists examine dust from the crash in the asteroid belt between Mars and Jupiter, which triggered an ice age on Earth.
A study of fossil meteorites suggests that a distant asteroid collision once sent Earth into an ice age.
An explosion of a 93-mile-wide asteroid somewhere between Mars and Jupiter created huge amounts of dust that rained down on Earth over a period of millions of years, filtering out sunlight.
The cataclysmic asteroid impact off Mexico's coast that doomed the dinosaurs 66 million years ago was not the only time an astronomical event shaped the history of life on Earth.
About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and the new range of temperatures around the planet set the stage for a boom of new species evolving. The cause of this ice age was a mystery, until now: a new...

Surprising results from recent asteroid missions have highlighted the importance of testing planetary defence strategies in space, according to scientists participating in the joint ESA/NASA Asteroid Impact and Deflection Assessment (AIDA) collaboration. The unexpectedly large crater on asteroid...
Our present moment is characterized by a growing obsession with the long term. The study of climate change, for example, relies on increasingly long-range simulations. Science's predictions are no longer merely hypotheses for validation or invalidation but are often grave threats--of growing...
From transport and housing to food production and fashion, our civilisation is driving climate and ecological breakdown.
Can artificial intelligence evolve and become more sophisticated when put in a competitive world, similar to how life on Earth evolved through competition and n...
Millions of years ago, the supercontinent Pangea broke up into land masses that became modern-day continents. One continent was buried under Europe.
