What is the Dictionary of Space Concepts?

The Dictionary of Space Concepts (DSC) is a project by UNIVERSEH – the European Space University of Earth and Humanity. Starting in 2020, this Alliance of five European Universities decided to launch an online dictionary dealing with terms and concepts related to space sciences. It should be created and used by students, lecturers, researchers and citizens alike.

After an initial planning phase, the DSC was published in spring 2022. It opens up several opportunities for all members of the UNIVERSEH Alliance and interested citizens to contribute to the content of the DSC.

In our course "Terms and Concepts of Space" (to the registration) , students learn how to write a dictionary article and later on contribute several entries to the DSC. Students and other members of the UNIVERSEH Alliance can also submit articles for the DSC via an entry in here . Interested citizens can contribute in this entry platform.

Once submitted, these articles are reviewed by UNIVERSEH Alliance staff and, if necessary, edited before their publication in the Dictionary.

In this way, the DSC is a dynamic project that is constantly expanding in content and quality through constant contributions from students, staff and citizens.

Zenith (Last edited: Monday, 28 August 2023, 12:33 PM)
Media Media Zenith & Nadir, DJ Jeffery, University of Nevada, Las Vegas, 2003. Definitions Short Definition Zenith is a point on the celestial sphere that is directly above the observer. The zenith is diametrically opposite to the nadir. Detailed Definition Zenith is determined by the direction of the gravitational force at particular point on Earth. Typically, the term implies astronomical zenith, that is, the point at which the imaginary line drawn from the geometrical centre of the Earth through the observer intersects with the celestial sphere. The angular distance from zenith is called the zenith distance of the celestial body. The zenith and the nadir form two poles of the horizon. Etymology From Medieval Latin cenit, from Arabic samt (ar-ra's)“path (over the head)” Sample Sentences Glowing with astral turquoise, the comet dashingly passed zenith and started decelerating as it was approaching the horizon.
