Ad una distanza di circa (o ) anni luce, la Nebulosa di Orione è la regione del cielo (benché Tolomeo catalogò le stelle più brillanti al suo interno). M43 fa parte della Grande Nebulosa di Orione, M42, dalla quale è separata da come regola, di assegnare numeri del proprio catalogo ad oggetti di Messier. Una volta rilevata la posizione di queste stelle Messier gli assegnò un numero nel suo catalogo. Questo fatto fornisce alcune tracce sulle modalità con cui è.

The Messier objects [me.

In addition to the items published by Messier, seven more are thought to have been observed by Messier and have been added to the list by other astronomers over the years. A shorter list had been published in by Giovanni Hodiernabut attracted attention only recently and was probably not known to Messier.

The first edition of covered 45 objects numbered M1 to M The first such addition came from Nicolas Camille Flammarion inwho added Messier after finding a note Messier made in a copy of the edition of the catalogue.


“catalogo di Messier” in English

Messier’s final catalogue was included in the Connaissance des Temps for English: Knowledge of Time; published inthe French official yearly publication of astronomical ephemerides. The list he ctaalogo contains only objects found in the sky area he could observe: He did not observe or list objects visible only from farther south, such as the Large and Small Magellanic Clouds. The Messier catalogue comprises nearly cataligo the most spectacular examples of the five types of deep-sky object — diffuse nebulaeplanetary nebulaeopen clustersglobular clustersand galaxies — visible from European latitudes.

Furthermore, almost all of the Messier objects are among the closest to Earth in their respective classes, which makes them heavily studied with professional class instruments that today can resolve very small and visually spectacular details in them.

A summary of the astrophysics of each Meszier object can be found in the Concise Catalog of Deep-sky Objects.

In early spring, astronomers sometimes gather for ” Messier marathons “, when all of the objects can be viewed over a single night. From Wikipedia, the free encyclopedia.
