Depicts several planets or planetoids (including a recognizable Saturn), four-point stars and the European Space Agency's Rosetta probe—the first spacecraft to orbit a comet—all in yellow. Empty space, along with some stars, are colored blue. The word KOSMOLOGIE is inscribed on the "pill", while the Republic of Austria, 25 EURO and 2015 are inscribed on the silver ring. Various scientific symbols, equations and graphs are in the background.

Planets (Jupiter, Earth etc.) and their orbits (in yellow) arc over the European Extremely Large Telescope (in blue). The details of the telescope on the coin overlap from the outer silver ring into the blue niobium core. The E-ELT has been called the "world’s biggest eye on the sky.” One of the key objectives of the E-ELT is to find other earth-like planets. It will also study the formation and demise of stars, planetary systems and the planets themselves. The telescope is located in the Amazonas region of the Atacama Desert in Chile, at an altitude of 3000 meters or almost 10,000 feet. It will be four times as large as the largest telescope currently in use. Construction on the E-ELT began in early 2014 and is expected to end sometime in 2022. The entire project is estimated to cost more than one billion euros.

The reverse also features the inscriptions MULTIVERSUM, UNIVERSUM, GALAXIE and SONNENSYSTEM, which mean "multiverse", "universe", "galaxy" and "solar system", respectively.
