Adam Hibberd In 2017, an interstellar object was discovered, the first ever to be detected. It was observed by the Hawaiian observatory Pan-STARRS, subsequently studied by many telescopes before disappearing into the distance in January 2018. An estimate on the number density, N (how many per unit volume), in interstellar space was determined based on […]

I have an answer to this which may to some degree be a personal one. The question boils down to why are we curious? […]
Exploring ‘Oumuamua’s Trajectory – Further Notes
Adam Hibberd November 2022 In my last blog I reported the progress of my work regarding the intriguing little conundrum of the first interstellar object (ISO) to be discovered, designated ‘Oumuamua, in particular my research into its orbit. In fact ‘Oumuamua is puzzling on many counts and I have also in a previous blog elaborated […]
Exploring ‘Oumuamua’s Perihelion Date

Mucking around in the sense of playing with its orbital parameters and seeing what crops up. Those of you who […]
Sailing to Apophis
Adam Hibberd September 2022 Of the existential threats posed by celestial objects to our Earth, the cradle of humanity and currently our only life-support, there are myriad such candidates. In fact we are in a veritable astronomical mine-field, the key question is not if but when. Take comets for instance. These objects composed primarily of […]
Skateboards to Starships
The third i4is summer workshops at the Royal Institution We were first invited to deliver a one day summer workshop for school students by the Royal Institution {RIGB, www.rigb.org) in 2018. We called it “Skateboards to Starships” to show that the basic physics, maths and engineering principles applied to both and at many scales between.We […]
