New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...
Maybe the first life on Earth was part of an 'RNA world.' Artur Plawgo/Science Photo Library via Getty Images How life on Earth started has puzzled scientists for a long time. And it still does.
In an investigation to find out what sparked life on Earth, researchers have discovered that RNA formed through surprisingly ...
How did life begin on Earth? While scientists have theories, they don't yet fully understand the precise chemical steps that ...

Armed with that information, the researchers went about gathering samples from the areas of land that are believed to be the ...
When Earth was a molten inferno, water may have been locked safely underground rather than lost to space. Researchers ...
Earth’s distant future has always been framed as a slow fade billions of years from now, but a new generation of models is painting a sharper and more unsettling picture. Instead of a gentle decline, ...
Four billion years ago, our then stripling sun radiated only 70 to 75 percent as much energy as it does today. Other things on Earth being equal, with so little energy reaching the planet’s surface, ...
MADISON – Reading the telltale chemical signature of a mineral sample determined to be the world’s oldest known terrestrial material, scientists have reconstructed a portrait that suggests the early ...
Earth may have gobbled up a Mercury-like body early in our planet’s history, and that may have helped create a heat source in our iron core—an energy source that would go on to generate the planet’s ...
Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.
