Astronomers are now certain that the mysterious object detected hurtling past our sun last month is indeed from another solar system. They have named it 1I/2017 U1(‘Oumuamua) and believe it could be one of 10,000 others lurking undetected in our cosmic neighborhood. The certainty of its interstellar origin comes from an analysis that shows its orbit is almost impossible to achieve from within our solar system.
It is thought to be an extremely dark object, absorbing 96% of the light that falls on its surface, and it is red. This color is the hallmark of organic (carbon-based) molecules. Organic molecules are the building blocks of the biological molecules that allow life to function. It is widely thought that the delivery of organic molecules to the early Earth by the collision of comets and asteroids made life here possible. ’Oumuamua shows that the same could be possible in other solar systems.
