Czech Involvement with ESO

The Czech Republic became the 13th member of ESO, when it joined on 22 December 2006 (eso0652). It was the first country from Central and Eastern Europe to join ESO.

The Czech Republic currently contributes 1.02% of ESO’s revenue, worth 1 657 000 EUR.

Discoveries by Czech astronomers using ESO telescopes

In March 2015, several Czech astronomers, based at the Astronomical Institute of the Academy of Sciences, spent years monitoring a dusty gas cloud orbiting the Black Hole at the centre of the Milky Way. They used ESO’s Very Large Telescope (VLT), in particular SINFONI and NACO. (eso1512)

In January 2017, Czech astronomers, also based at the Astronomical Institute of the Academy of Sciences, were involved with taking the first images of the Sun with the Atacama Large Millimeter/submillimeter Array (ALMA). This revealed new features, in particular the dark centre of a cold sunspot, almost twice the size of Earth. (eso1703).
