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 ...

Extraterrestrial life may look nothing like life on Earth—astrobiologists seek framework for how complex systems evolveAs life evolved on Earth, it used and created minerals for exoskeletons and habitats. The hundred minerals present when life first formed have grown to about 5,000 today. For example, zircons ...
