Study Finds How 'Fortunate' Earth Became Suitable For Life
The experts can use these findings in their search for life on exoplanets with similar chemical profiles.
-
Scientists Predict Exact Date Life On Earth Will End: Study
A supercomputer simulation predicts that life on Earth will end in 1 billion years due to the depletion of oxygen caused by the Sun's increasing heat and brightness, ultimately rendering the planet uninhabitable.
-
New Chemical Reactions Can Help Explain Origin of Life From Non-Living Molecules
Scientists at Scripps Research have discovered a new set of chemical reactions that can produce the building blocks of life. They have found a set of chemical reactions that can produce amino acids and nucleic acids — the building blocks of proteins and DNA — by using cyanide, ammonia, and carbon dioxide.

Asteroid Calamity Shaped Life On Earth 466 Million Years Ago: Study
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.
-
Not Many 'Habitable' Planets Can Harbour Life: Study
"It was previously assumed that planets with masses similar to Earth would be habitable simply because they were in the 'habitable zone'."
-
Violent Young Sun May Have Seeded Life on Earth: Study
Super-flares could've smashed nitrogen in Earth's air to yield a greenhouse gas, nitrous oxide, as well as hydrogen cyanide, which produces the building blocks of proteins.
-
Comet Craters Helped Create Conditions for Life on Earth: Study
According to the researchers, impact craters were ideal environments to facilitate the reactions that saw the first "seeds of life" take root.
-
Scientists Propose New Theory About How Life Originated on Earth
Researchers said hydrocarbons and other products were transported to Earth by asteroids or comets, and continued to evolve in the planet's unique "goldilocks" conditions.
-
Life on Earth May Have Started 4.1 Billion Years Ago, Says Study
Life on Earth may have started at least 4.1 billion years ago - 300 million years earlier than previously documented, a new study suggests.
-
'Oxygen Fluctuations Stalled Life on Earth'
Know why life on earth stalled for more than a billion years after making the first appearance 2.3 billion years ago? It was because of massive oxygen fluctuations that brought a billion-year hiatus called "boring billion" in evolution.
