A few years ago, together with my sister, we started a small but very special project in my hometown, Katerini, Greece. We called it the "Magical University", an initiative designed…
We live in an age where we constantly talk about Artificial Intelligence. As a scientist, I find this development fascinating. I have used computers and algorithms throughout much of my…
Picture this: you are on a rocket departing Earth. You go very high up, reach the edge of the atmosphere and as you go further and further away, the Earth…
At the closing remarks of the Olympian Symposium 2026, I shared a simple thought: science moves forward through ideas, but ideas are made by people. Behind every discovery, there are…
For almost twenty years, I have been trying to understand the Universe. I have studied stars, galaxies, molecular clouds, and the physics and chemical laws that shape them. I have…
I first heard this story from the historian Eleni Glykatzi-Ahrweiler. She once spoke about a Nobel Laureate who was asked which stage of his education had been the most important.…
Astrochemistry has been widely developed as a power tool to probe the physical properties of the interstellar medium (ISM) in various conditions of our Galaxy, and in near and distant…
Determining the photodissociation region (PDR) properties of the interstellar medium (ISM), such as the atomic and molecular mass content, is of fundamental importance to understand the star-formation process. The advent…
To determine the physical properties and evolution of the interstellar medium (ISM), we need to model its chemical conditions, since these help set its heating & cooling rates and ionization…
Cosmic-rays are relativistic charged particles (and not "rays" in terms of electromagnetic radiation) and play an important role in regulating the chemistry at high column densities. These high column-densities are…
