Dictionary of Space Concepts
The Dictionary of Space Concepts (DSC) provides not only the basis for the advanced English language classes of the Multilingualism Programme; it also serves as larger online support platform for all UNIVERSEH students, with the aim of training specific space terminologies across various fields connected to the space sector. The DSC combines core space concepts and with helpful illustrations, all in an open-project format, which is freely available to everyone inside and outside UNIVERSEH. We welcome your contributions, comments, and expertise!

A dwarf galaxy is a galaxy made up of material and dark matter ejected from larger galaxies by the force of gravity. Although a dwarf galaxy is defined by astronomers by the number of stars it contains, and hence its size, it is also defined as dwarf by its shape, content, and even appearance. Detailed Definition: Dwarf galaxies, formed from fragments of larger galaxies, are the most abundant type of galaxy in the universe. Dwarf galaxies are galaxies that break apart due to their relatively small size to their neighbors, causing stellar streams and galaxy mergers. However dynamic these relationships with neighboring galaxies may be, they are difficult to detect by astronomers due to their low light, mass and small size. The astronomical importance of these dwarf galaxies actually comes from their tendency to form from other large galaxies and merge again with larger galaxies. Their difference from the usual galaxy shape is that they have low metallicity and gas in abundance. This situation is used by astronomers as evidence to interpret the motion and evolution of galaxies. Dwarf galaxies are basically divided into three groups: Dwarf elliptical galaxies, dwarf spheroidal galaxies, and dwarf irregular galaxies. Etymology: From Old English ‘Dweorg’ + From Latin ‘Galaxias’ Sample Sentence(s): ‘’The most powerful space telescope currently operating has zoomed in on a lonely dwarf galaxy in our galactic neighborhood, imaging it in stunning detail.’’ (Lea, R.
