However, Trump has declared that he was “not satisfied” with the status of the talks, fuelling worries that the world’s top two economies could still slug out an economically pain
Astronomers have found evidence of buckyballs - carbon molecules shaped like soccer balls - in the nebula around a distant white dwarf star. The discovery marks the largest molecules known to exist in space. Normally found in chemistry labs, where they are made by vaporizing graphite in the presence of helium, buckyballs were long suspected to form inside stars. "As soon as they were discovered in the lab it was actually suggested they would be very good candidates to be found in space," astronomer Jan Cami of the University of Western Ontario, who led the new study, told SPACE.com. Elusive buckyballs Researchers had searched for buckyballs before in the gas and dust between and around stars, but the evidence was inconclusive. Cami and his colleagues identified buckyball molecules, known as C60 because they are made of 60 carbon atoms each. The buckyballs are about 1 nanometer in size, about three times larger than water molecules, which are abou
