M33 - TSA102S
M33 - Triangulum Galaxy
|
The Triangulum Galaxy (also known
as Messier 33 or NGC 598) is a spiral galaxy
approximately 3 million light-years away in the
constellation Triangulum. The galaxy is also
sometimes informally referred to as the Pinwheel
Galaxy by some amateur astronomy references and in
some public outreach websites. However, the SIMBAD
Astronomical Database, a professional astronomy
database that contains formal designations for
astronomical objects, indicates that the name
"Pinwheel Galaxy" is used to refer to Messier 101,
and several other amateur astronomy resources and
other public outreach websites also identify
Messier 101 by that name. It is the third largest
galaxy in the Local Group, a group of galaxies
that also contains the Milky Way Galaxy and the
Andromeda Galaxy, and it may be a gravitationally
bound companion of the Andromeda Galaxy. The
Pisces Dwarf (LGS 3), one of the small Local Group
member galaxies, is possibly a satellite of
Triangulum.
The Triangulum Galaxy can be
seen with the naked eye under exceptionally good
conditions. While the fainter and more distant
galaxy Messier 81 has also been seen with the
naked eye by very experienced observers, M33 is
often considered the most distant object that can
be seen without aid. However, some amateur
astronomers may confuse the object with the nearby
NGC 752, an open cluster that is brighter than the
Triangulum Galaxy. No known pre-telescopic
observer notes it, which is not surprising: given
its indistinctness, it is not likely to be noticed
as an object unless one already knows of its
existence.

Public Viewing
Nights |
|
Just to let
everyone know, public viewing nights are held
every first Friday of the month. Clear or cloudy
nights the public viewing night goes ahead.
Members man a number of telescopes of various
sizes and types, and for those nights where the
sky is cloudy, extended astronomical presentations
are presented in the MPAS Viewing Centre.
So please come
along and enjoy our nights sky.
