Let Constellation begin!

by Fabio

“¡Hola! ¿Que tal? ¡Mucho gusto hablar con ustedes!” These words opened a video conference between two italian cities and two chilean ones, in mid April.

Mauricio, a school teacher at Cariquima in northern Chile, introduced his students to us. It was a fantastic moment, a new beginning for an idea on which GalileoMobile has been working on for many months: Constellation. The students were very excited to speak about their school and themselves with people living on the other side of the planet.

Many similar conversations, connecting Paris with Bogotá, London with AltoBioBio, Marseille with Cusco, Berlin with Los Antiguos, New Haven with Quito, and Munich with Medellin are now taking place. Contact has been made and we are ready to begin this adventure.

This month Constellation enters one of its main stages: GalileoMobile will start working with teachers and students in the 21 schools making up our network in South America. We have prepared a book of activities that we hope will prove useful in approaching important topics in astronomy. We are eager to discuss them in detail over many video conferences with the schools over the next few months.

We are sure that the students will have as many ideas and questions as there are stars in the sky. And when we have answered all of those, there will always be a new one waiting to be taken care of.

Let GalileoMobile Constellation begin!

The Moon was fighting the Sun

By Fabio

The magic has happened again: deep, tongue-tying darkness in the middle of a sunny day.

It was really cold: my hands started freezing as soon as I took off my gloves to capture this day in some pictures.

The light began changing gradually, from ten in the morning onwards, turning the surrounding mountains from white into a sort of yellow mixed with red.

A hot-air balloon was sailing the south-eastern blue sky, where a sundog was shining. Then it moved towards the Sun, perhaps trying to help the Moon to obscure our star. But this traveler of the air didn’t dare to interfere with the fight, and thus passed below the Sun, kept moving south, and finally disappeared behind the ridges of arctic mountains.

I was checking the solar disk through my solar-filter glasses, taken at UNIS yesterday morning. The Moon was about to win the fight with the Sun, which did surrender, with a final breath, some minutes past eleven.

The whole valley suddenly turned into an unknown place, a landscape of one of the extraterrestrial lands that humans will, one day, discover, touch, explore.

Then, the magic: our star took back its place in the terrestrial sky, the Moon was convinced to give up the fight.

The Sun irradiated the humans with its light and love. One can entirely understand them only after a storm of darkness.

The day before the eclipse

It is a sunny day in Longyearbyen, Svalbard Archipelago, the day before the spring equinox.
Many people came here with the hope of observing the Moon passing between them and the Sun, transforming two and a half minutes of a normal day in a surrealistic night.

Svalbard islands are located far beyond the polar circle, in the middle between the Barents Sea, the Greenland Sea and the Arctic Ocean. The few inhabitants of this land have a quite unique relation with the Sun, a star which never shows up during many months in the winter, from October till February, and which is always present in the sky from April until August. Between February and April, instead, the length of the daytime changes rapidly, from zero up to 24 hours.
Now that I am here I can see and live this ongoing change, and every day is approximately one hour longer than the previous.
Tomorrow, suddenly, daytime will have a sort of hiccup and sunlight will shut down for some minutes.

Today I took a walk to Adventalen, a valley just in front of Longyearbyen, the place where tomorrow I will wait the arrival, and the departure, of the shadow of the Moon. It is a snow-covered tundra surrounded by mountains on all its sides but one, washed by the water of Adventfjorden, a tiny ramification of the Atlantic ocean.

When I was there, a few hours ago, I was thinking of all the guys we met in Uganda two years ago, and of our discussions about the solar Eclipse. In 2013, a few weeks before a Solar eclipse took place in Uganda, together with other Galileonauts I traveled to this equatorial country for the GalileoMobile expedition “In the Land of Beauty”.
During this travel I learned that eclipse, in Lugiso, one of the Ugandian languages, is “Inyanga ili khukhupana ni Kumwesi” – The Sun is fighting the Moon.
Tomorrow this fight will take place once more, following the cycles of celestial mechanics, and a bunch of humans will be, once again, overwhelmed by the majesty of the cosmos, in the Arctic just like at the equator, always under the same sky.
