2019 Perseids: spectacular cometary fragments

Posted in MiARD

Occurring every August, the Perseid meteor shower will peak in 2019 on August 12-13th (unfortunately close to full moon on 15th August), but meteors from this group can be seen in night skies for a few weeks either side of this date. For more background information about meteor showers and how to best observe them, see e.g. https://theconversation.com/explainer-why-meteors-light-up-the-night-sky-35754 .

The Perseid meteors are tiny fragments of the Comet Swift-Tuttle,entering the Earth’s atmosphere at about 58 kilometres per second (or two hundred and nine thousand kilometres per hour!).

A number of scientists who worked on the MiARD project have subsequently contributed to a recent paper in the journal Nature that seeks to explain how comet 67P/Churyumov-Gerasimenko got its current shape. See Bilobate comet morphology and internal structure controlled by shear deformation  

A summary in lay person’s language has been provided by ESA.

Video of talk

Posted in Comet 67P, MiARD, Modelling, Rosetta

Scientist Raphael Marschall from the MiARD project recently gave a talk to the Bern section of the ‘Astronomy on Tap’ movement that seeks to provide popular science talks with an astronomy theme to the general public in an informal setting. A video of his talk can be seen here, in which he summarises the reasons for studying comets, and his own research using results from the ROSETTA mission.
