Andromeda Nebula Lies Outside Milky Way Galaxy

Curtis stated that bright diffuse nebulae are fairly close to Earth and are part of the Milky Way, while spiral nebulae are at great distances and not part of the Milky Way
Messier Object 31
It was William Huggins, the pioneer of spectroscopy, who noted in 1864 the difference between gaseous nebula with their line spectra and those "nebulae" with star-like, continuous spectra, which we now know as galaxies, and found a continuous spectrum for M31 (Huggins and Miller 1864). It is still not clear if M33, the smaller spiral galaxy in Triangulum, and its probable companion LGS 3 belong to this subgroup, or the more remote Local Group member IC 1613, or one of the possible member candidates UGCA 86 or UGCA 92

Hubble Finds Giant Halo Around the Andromeda Galaxy
.......they measured the mass alright, but you forgot to read their conclusion about the "mass" of the halo: "The gargantuan halo is estimated to contain half the mass of the stars in the Andromeda galaxy itself, in the form of a hot, diffuse gas." Dark matter really is not that weird of an idea. Could the Milky Way become a quasar? February 27, 2015 A quasar is what you get when a supermassive black hole is actively feeding on material at the core of a galaxy
If you are lucky enough to be able to observe the Andromeda Galaxy through a small telescope or a good pair of binoculars, it is obvious that most of its light comes from a very bright central core. Think about what you are really seeing: It is a whole other GALAXY, not an object within our own Milky Way! The Andromeda Galaxy is about 2.5 million light-years away and is about 200,000 light-years across
Observing M31, the Andromeda Galaxy
M 31 lies at a distance of 2.4 million light years, but on a clear night you can see it without any optical aid from a moderate observing site, as a small and fuzzy patch of light of the 4th magnitude. With Bresser 7x50 binoculars from my own backyard (450 feet altitude) From my own backyard I regularly observed M 31 with 7x50 Bresser binoculars (field of view 6.1 degrees)
The Space Telescope Science Institute (STScI) in Baltimore conducts Hubble science operations and is operated for NASA by the Association of Universities for Research in Astronomy Inc. The Andromeda Galaxy, also known as Messier 31 or M31, is the most massive galaxy in the Local Group of galaxies that also includes the Milky Way and about 45 other known galaxies
A side-by-side comparison of the two primary mirrors shows that the collecting area of the James Webb telescope is over five times bigger than that of Hubble. It shows the startling scale of just our local neighborhood in the universe, and may be one of the most awe-inspiring images produced from the almost 25 years of service by the space telescope

BBC Universe - The Andromeda galaxy is our galactic neighbour
Melvyn Bragg and guests discuss the galaxies; spread out across the void of space like spun sugar, but harbouring in their centres super-massive black holes. This clip looks at some of the American astronomer Edwin Hubble's most important contributions to astronomy and the equipment he used at the Mount Wilson Observatory
Andromeda: Hubble mosaic of the spiral galaxy.
Using six filters means stars can be categorized by color (which in turn tells us much about their mass, age, temperature, and more), and a lot of the dynamics and evolution of Andromeda will be discernible. And here we are, decades later, looking at them effortlessly on our computers, thanks to a telescope bearing his name and the hard work of a lot of folks putting this image together
The two galaxies, about 2.6 and 3 million light-years, respectively, from Earth, are members of the Local Group of galaxies that includes our own Milky Way and about 30 others. The new observations confirm a disputed 2004 discovery of hydrogen gas streaming between the giant Andromeda Galaxy, also known as M31, and the Triangulum Galaxy, or M33
Most of the stars in the universe live inside such majestic star cities, and this is the first data that reveal populations of stars in context to their home galaxy.A compass and scale image of the PHAT program mosaic. Because the galaxy is only 2.5 million light-years from Earth, it is a much bigger target in the sky than the myriad galaxies Hubble routinely photographs that are billions of light-years away
You see, Andromeda is the largest of all spirals in the night sky from our vantage point; regardless of what it was, it was reasonable to assume the reason it was so big is because it was closer to us than all the others. You have an apparently star-less extended nebula, that only resolves into an enormous number of stars when viewed with a huge telescope, and a star coincident in the sky with that object that is an enormous distance away
These observations were made between 2004 and 2007 to observe a wide variety of stars in Andromeda, ranging from faint main sequence stars like our own Sun, to the much brighter RR Lyrae stars, which are a type of variable star. The purpose of these observations also explains their exceptional depth: to gain useful data on dim, distant stars, a long series of individual exposures had to be made in each field
Answered by: Colby Hayward, Computer Support Technician, Ontario, Canada The distance to Andromeda was first determined (inaccurately) by Edwin Hubble in the late 1920's. Since all these Cepheids were in the SMC, she reasoned that they were all about the same distance away, so there should also be a linear relationship between their periods and their true brightnesses (how bright they would look at a standard distance)

This is a circumpolar constellation, which means that it is always above the horizon at mid-northern latitudes, opposite the North Star, Polaris, from the Big Dipper

If you're already familiar with using a telescope, you will be aware that its narrower field of vision than binoculars can make the targeting more precise and consequently harder.
