Asteroid samples hint at how life formed on Earth, researchers say
When asteroids like Bennu hit the young Earth, they could have provided a complete package of complex molecules and the ingredients essential to life, such as water, phosphate and ammonia. Together, these components could have seeded Earth’s initially barren landscape to produce a habitable world.
Samples of organic matter returned from the asteroid Bennu support the theory that asteroids could have brought the building ...
A team of scientists discovered that the near-Earth asteroid, known as Bennu, contains a wealth of minerals and organic molecules, including many that are building blocks of life. But what has the 4.5 ...
In a new peer reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor is the single life form that branched into ...
In fact, this contamination by life is probably the normal beginning of life on any planet, including the earth. “Space travelers,” says Gold, “may have visited the earth a billion years ago ...
The Bennu discovery helps to illuminate how, early in the Solar System’s history, asteroids and other planetary building blocks were not just “lumps of stone and ice, but active ‘living’ objects”, ...
