A chemist turned science writer, Victoria Corless completed her Ph.D. in organic synthesis at the University of Toronto and, ever the cliché, realized lab work was not something she wanted to do for the rest of her days.
Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesCosmic dust may have helped to kick-start life on Earth, new research suggests. The findings challenge a widely held assumption that this was not a plausible explanation.has long remained a mystery.
In the Nature Astronomy study, the scientists investigated whether fine-grained"cosmic dust" could provide an answer. This granular material is produced in Using astrophysical simulations and geological models, the team sought to quantify the flux and composition of cosmic dust that might have accreted on Earth's surface during the first 500 million years following an event known as the moon-forming impact — a theory that. After comparing the results to estimates of the present-day accretion on Earth, the team found that the total accretion of cosmic dust on early Earth may have been 100- to 10,000-fold higher than that observed today.
