Diverse microbial life existed on Earth at least 3.75 billion years ago, suggests a new study that challenges the view of when life began.

Surprisingly we do not have much information about the center of the planet that we live on. What lies beneath our feet is not well known.

Where did the ice sheets that rang in the last ice age more than 100,000 years ago come from, and how could they grow so quickly?

Unlike in Star Trek, here on nonfictional planet Earth, Borgs are DNA packages that could help humans fight climate change.

Water is essential for life on Earth and other planets, and scientists have found ample evidence of water in Mars’ early history.

Findings suggest a variety of microbial life may have existed on primordial Earth, potentially 300 million years after the planet formed.

A new study suggests that many more planets may have large amounts of water than previously thought—as much as half water and half rock.

Determining what killed the dinosaurs 66 million years ago at the end of the Cretaceous Period has long been the topic of debate.

Invaders, pirates, warriors – the history books taught us Vikings were brutal predators who travelled by sea from Scandinavia to pillage.

The accepted view of Mars is red rocks and craters as far as the eye can see. That’s what scientists expected when they landed Perseverance.

The stone named Hypatia from the Egyptian desert could be the first tangible evidence found on Earth of a supernova type Ia explosion.

Scientists can make some pretty accurate forecasts about the future, but predicting what the Earth will be like in 500 years is difficult.

As a planet grows, it accumulates material from its surroundings, so its composition reflects the environment in which it formed.

Earth's core is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core.

Earth’s plates might be shifting because the sun exerts such a strong gravitational pull on the moon that its orbit is elongating.

New tech offers pathway for instantly converting CO2 as it is produced and locking it in a solid state, keeping it out of the atmosphere.

Scientists have shown how the freezing of a ‘slushy’ ocean of magma may be responsible for the composition of the Moon’s crust.

Earth may have experienced cycles of dryness followed by massive rain storms hundreds of miles wide that could dump feet of rain per hour.

There are five significant mass extinctions, known as the "big five," where at least three-quarters of all species died.
