Abstract: The discovery1 of 1I/2017 U1 (1I/‘Oumuamua) has provided the first glimpse of a planetesimal born in another planetary system. This interloper exhibits a variable colour within a range that is broadly consistent with local small… read more here.

Abstract: That the interstellar object 1I/2017 U1 (‘Oumuamua) could be an extraterrestrial artefact is an unorthodox hypothesis. From a philosophical perspective, however, the structure of the underlying argument for the hypothesis is flawed. read more here.

DOI: 10.1089/ast.2021.0199
Abstract: The interstellar objects 1I/'Oumuamua and 2I/Borisov confirm the long-held expectation that bodies from one stellar system will be carried to another, allowing, in principle, interstellar panspermia. Life might be transferred between stellar systems, depending on… read more here.
