Cooking… and the universe

Wednesday has become the regular appointment with my “From the kitchen” posts. Today I have no recipe to share, or better, no good pictures of the recipes I wish to share (we were too fast eating them!).

I thought of what I could post about gastronomy… and remembered a quote of a Greek film where the uncle of the main character tells him that the word “gastronomy” includes the word “astronomy”… he showed him a connection between cooking and stars… I found it so inspiring that after 20 years I still remember it.

So here is my astronomy post, with my recent sources of information about the immense, black, mysterious universe around us.

First, ESA’s Picture of the Week that features breathtaking images such this one of NGC 278 in the constellation of Cassiopeia:

Then I present you the project GalaxyZoo, an online citizen science project, that offers everyone a simple tool to help classifying the immense number of galaxies detected by the world’s most powerful telescopes. Citizen science is a way of including non-specialists into actual science projects. I dislike how science is commonly left to specialists, when anyone with just a little patience, curiosity and love for precision can produce high-quality data for further analysis. This has been demonstrated by the many phases of GalaxyZoo, which allowed many scientists to publish papers based on these galaxy classification datasets; and by bird-watchers in many countries, who accurately recorded presence data on extensive areas, an effort that scientists could not imagine to attempt through regular sampling expeditions. It remembers me strongly of the collective mapping of OpenStreetMap. Of course a single contributor makes mistakes, but the strength of this model is in the many eyes that cross-check contributions and improve the dataset every day. And as a former (or dormant?) scientist myself, I know that specialists are not immune to errors either – and that’s why they resort to peer review and collaboration. See the timeline of ceratopsian research – even only the pictures – to see how many attempts were made, how many times some data have been reinterpreted, how many hypoteses have been remodeled and thrashed to come to our present understanding of these dinosaurs. But I am stuffing too many topics in this post! I will expand them in future posts.

Until then, I wish you all a relaxing and cheerful festive season, wherever you are all around the world!
