This fall, Bannister's colleague Alan Fitzsimmons produced the first-ever detection of a chemical compound emitted by an interstellar comet. Separating light from 2I/Borisov into its component parts, his team found a signature of cyanogen, a molecule made of a carbon atom and a nitrogen atom

Sneaky Meteor Evades Earthling Detection, Explodes with Force of 10 Atomic Bombs
likely due to its smallish size. Alan Fitzsimmons, an astronomer at Queens University Belfast in Northern Ireland, told New Scientist that most modern telescopes are best able to detect objects measuring several hundred meters or more in diameter, making smaller objects like this one easy to miss.

Interstellar visitor might be a comet covered in carbonaceous crud
A new study led by Alan Fitzsimmons of Queens University Belfast carefully analyzed the wavelengths of light in observations of Oumuamua by two telescopes in late October. The study's analysis confirms that theres no sign of even a faint tail, but the wavelengths that correspond to rocky minerals

Asteroid hitting Earth very much possible, warns scientist
It is a case of when an asteroid collision will happen, rather than if it will happen, said Alan Fitzsimmons. Fitzsimmons was highlighting the threat for Asteroid Day, a global event on June 30. On that day in 1908, a small asteroid exploded over Tunguska in Siberia and devastated 800 square miles.
Comet Swift-Tuttle wont be visiting our neck of the woods again until the year 2125, but every year we get this beautiful reminder as the Earth ploughs through the debris it leaves in its orbit said Professor Alan Fitzsimmons of Queens University Belfast.
