Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts.
Researchers at The Open University (OU) and The University of Manchester have found conclusive proof that Ancient Egyptians used meteorites to make symbolic accessories.
A study of water from the Martian interior shows that Mars was originally formed from similar building blocks to Earth, but evolved differently later on.
Not only was there once water on Mars - some of it was warm enough to support life, an analysis of meteorites shows.
There's vastly more water in Mars's mantle than previously thought - as much as on Earth, in fact - dramatically raising the chances that the planet might once have sustained life.
An analysis of meteorite samples has revealed that there's more than one way of building amino acids in space, raising the odds of life elsewhere.
All the gold in the Earth's crust was delivered there by meteorites, accoring to researchers at the University of Bristol.
The building blocks of DNA have been arriving here from meteorites in greater quantity than previously thought, lending weight to the idea that the seeds of life on Earth originated in space.
Ammonia brought to Earth by meteorites could have helped kick-start life, says a team at Arizona State University.
Creationists still won't like it, but a new study indicates that the Earth is rather younger than previously believed - up to 70 million years younger, says the team.
Far from wiping out life on earth, heavy meteorite bombardment four billion years ago could have given a boost to the microbes that were our ancestors, new research has found.
