Şunu aradınız:: vortress nebulae (Hollandaca - İngilizce)

in 1828 publiceerde hij "a catalogue of nebulae and clusters of stars in the southern hemisphere observed in new south wales", dat 629 nevelige objecten beschreef.
between june 1823 and february 1826 dunlop then made 40,000 observations and catalogued some 7385 stars, of which included 166 double stars and references to several bright deep-sky objects near the bright stars he catalogued.

it does not seem unreasonable therefore to think that the greater part of the material masses in the universe is found, not in the solar systems or nebulae, but in 'empty' space.
we have assumed that each stellar system in evolutions throws off electric corpuscles into space.

==scientific goals=====stars and resolved stellar populations===muse has a field of view that is well-matched to a number of fascinating objects in the milky way, such as globular clusters and planetary nebulae.
