Nostos: A journey to space, a journey to home
We are literally made of stardust!
Our mission is to return to our roots, hidden in the heart of the stars, through a journey of exploring nature. Like many heroes in mythology, this journey will bring us a deeper understanding of ourselves and our position within the Cosmos, to finally meet our better self.
We are physically very small, and the more we reach the sky beyond our limits, the more we realise how limited our senses and skills are. We are filled with awe every time we observe the stars, the Earth, the sea… because they are so perfectly created. And every time, we learn something new for the natural world and ourselves.
As trained scientists and nature lovers we appreciated early on that there is a lot more beyond ourselves and what our senses can grasp. We use experience-based learning, where observations stimulate our imagination to gain a wider understanding of the natural world.
For us, observing and studying the natural world is a truly active relationship, where one must be respectful to gain the benefits of this experience.
The holistic perspective requires several tools, including science, philosophy, and meditation to reach the goals of better self-understanding within the Universe.

Private events can be customised to your interests and include topics like:
- Navigation: mapping and measuring the sky.
- Telescopes: how to set up and use a telescope?
- Moonwalk: Explore our only natural satellite, it’s seas, mountains and rocks.
- Planet tour: Explore the planets of our Solar System.

About us

Anastasia Kokori
Anastasia is passionate about life, learning, and sharing this knowledge with others!
Anastasia is now a PhD candidate at UCL, London, with a Research Excellence Scholarship. She has studied and got certified in a wide range of subjects: Primary education, Science communication, Journalism, Space studies, Planetary science, Astronomy, Yoga teaching, Perfume making. She also enjoys scuba diving (ADIP 3 star diver), singing, and any type of sports.
Anastasia has worked in several observatories among which are the historical Royal Observatory Greenwich in London, UK, and also in the Blackrock Castle Observatory in Cork, Ireland.
During the previous years, Anastasia has been traveling a lot, meeting with several diverse communities. One of her main challenges is always to make things as easy to understand as possible and bridge the gap between science and society, between the natural and the theoretical studies. Overall, she tries to bring together communities from different backgrounds, so that everyone can see that all things are based on the same roots. By connecting small dots from different fields together, Anastasia strongly believes that humanity can gain a better understanding of itself.
Angelos Tsiaras, Dr.
Angelos is passionate about studing the natural world, nearby or very far away!
Angelos has a PhD in Astronomy from UCL, UK, and is a Physicist graduated from the Aristotle University of Thessaloniki in Greece. He was working as a researcher at UCL and at the Arcetri Observatory in Florence or the last six years.
He is an expert in astronomical data analysis, both with ground-based and spaced-based telescopes, like the Hubble Space Telescope and the James Webb Space Telescope. His field of rearch is Exoplanets – planets that orbit other stars, not the Sun, and he is an active member of the Ariel space mission, developed by the European Space Agency.
One of Angelos’ goals is to bring science closer to the society. In his vision, scientists will have a more active role in society, and, on the other hand, citizens will have a more active role in science. In this context, he dedicates a lot of time on engaging the public, students, and amateur astronomers, with research.
