Charles Messier
(26 June 1730 – 12 April 1817) was a French
astronomer
most notable for publishing an
astronomical catalogue
consisting of
deep sky objects
such as
nebulae
and
star clusters
that came to be known as the 110 "
Messier objects
". The purpose of the catalogue was to help astronomical observers, in particular
comet
hunters such as himself, distinguish between permanent and transient objects in the sky.
Messier's life
Messier was born in
Badonviller
in the
Lorraine
region of France, being the tenth of twelve children of Françoise B. Grandblaise and Nicolas Messier, a
Court usher
. Six of his brothers and sisters died while young and in 1741, his father died. Charles' interest in astronomy was stimulated by the appearance of the spectacular,
great six-tailed comet
in 1744 and by an annular
solar eclipse
visible from his hometown on 25 July 1748.
In 1751 he entered the employ of
Joseph Nicolas Delisle
, the astronomer of the
French Navy
, who instructed him to keep careful records of his observations. Messier's first documented observation was that of the
Mercury transit
of 6 May 1753.
In 1764, he was made a fellow of the
Royal Society
, in 1769, he was elected a foreign member of the
Royal Swedish Academy of Sciences
, and on 30 June 1770, he was elected to the
French Academy of Sciences
.
Messier discovered 13 comets :
