Meteorites are fragments of asteroids which find their way to Earth as shooting stars and provide information on the origins of our solar system. A team of researchers has examined the so-called ...

Scientists detected all five nucleobases in asteroid Ryugu samples, suggesting the key building blocks of DNA and RNA are ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

A pair of new studies suggest that key steps toward life’s chemistry may begin long before planets exist. Experiments simulating interstellar space show that simple amino acids can link into peptides, ...

The film explains the fundamental concepts of matter, focusing on atoms and molecules. It highlights that everything in the world is made up of atoms, which combine to form molecules. There are over ...

The ancient Greeks conceived of five building blocks of matter – from bottom to top: earth, water, air, fire and aether. Aether was the matter that filled the heavens and explained the rotation of the ...

Trevor Ireland receives funding from The Australian Research Council for research into the Ryugu samples. He is affiliated with the Hayabusa2 mission. How did life come about? The answer to this ...

A NASA spacecraft brought samples from the asteroid Bennu back to Earth in 2023. The first in-depth analyses of that material have revealed organic molecules, including building blocks of life. The ...

All four of the key DNA building blocks have now been found in meteorites, suggesting that space rocks may have delivered the compounds to Earth, contributing to the origin of life. DNA has a ...

Scientists detected all five nucleobases -- building blocks of DNA and RNA -- in samples returned from asteroid Bennu by NASA's OSIRIS-REx mission. Japanese collaborators detected all five nucleobases ...
