They could also have delivered similar building blocks of life to other planets. Scientists at Cambridge University propose that comets may "bounce" around the universe, carrying the essential ingredients to create life on alien worlds. They specifically looked at systems carrying rocky planets around low-mass stars — stars that are smaller than our sun. AdvertisementStill, Bonsor said the research suggests a low-mass planetary system is less likely to carry life than a system with a brighter star. "We're all super excited in the community about the fact that we can find habitable zone planets around low-mass stars.
