Swift Mission Observed Water from Interstellar Comet Borisov
For the first time, NASA’s Neil Gehrels Swift Observatory tracked water loss from an interstellar comet as it approached and rounded the Sun. The object, 2I/Borisov, traveled through the solar […]

The Carbon Monoxide-rich Interstellar Comet 2I/Borisov
Interstellar comets offer direct samples of volatiles from distant protoplanetary disks. 2I/Borisov is the first notably active interstellar comet discovered in our solar system[1]. Comets are condensed samples of the […]

Water Production Rates And Activity Of Interstellar Comet 2I/Borisov
We observed the interstellar comet 2I/Borisov using the Neil Gehrels-Swift Observatory’s Ultraviolet/Optical Telescope. We obtained images of the OH gas and dust surrounding the nucleus at four epochs spaced before […]

FLAMINGOS-2 Infrared Photometry of 2I/Borisov
2I/Borisov is the second interstellar object (ISO) after ‘Oumuamua (Meech et al. 2017), but differs from ‘Oumuamua drastically with its extensive cometary activity. A key ingredient to understand the nature […]
