Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected.
The detection of the interstellar comet 3I/ATLAS in July produced quite the stir in the scientific community. This comet is the third interstellar object (ISO) to pass through the Solar System, the previous two being 1I/'Oumuamua and 2I/Borisov, which arrived in 2017 and 2019, respectively. Like its predecessors, the arrival of 3I/ATLAS highlighted just how common these objects are and inspired mission concepts for studying them up close. The latest comes from the Southwest Research Institute (SwRI), where a team has developed a mission study for a spacecraft that could perform a flyby with 3I/ATLAS.
