NASA shows largest image ever of Andromeda Galaxy
Each of those white dots is a sun, much like the sun that powers all life on Earth.A vivid green aurora is reflected in the Jokulsrion Glacier lagoon at Vatnajokull National Park in Iceland
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

Since the full image boasts 1.5 billion pixels and needs a whopping 600 HD TVs to display in full, we'll just link you to a page where you can zoom in and look at small parts of the picture in detail
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

The properties of these gaseous halos control the rate at which stars form in galaxies according to models of galaxy formation," explained the lead investigator, Nicolas Lehner of the University of Notre Dame, Indiana. The team also determined that it is enriched in elements much heavier than hydrogen and helium, and the only way to get these heavy elements is from exploding stars called supernovae
Hubble Space Telescope Takes Sharpest-Ever Image of Andromeda
She originally hails from Knoxville, Tennessee where she and her family would take trips to dark spots on the outskirts of town to watch meteor showers every year. Since then, she has floated in weightlessness on a zero-gravity flight, felt the pull of 4-Gs in a trainer aircraft and watched rockets soar into space from Florida and Virginia

The research team plans to use Spitzer to obtain deeper observations of the galaxy, which should yield confident detections as well as estimates of the object's age and dust content. "We have to arrange the mass in the cluster so that it deflects the light of each galaxy to the positions observed." The team's analysis revealed that the cluster's mass distribution produced three lensed images of MACS0647-JD at the positions and relative brightness observed in the Hubble image
APOD: 2012 May 18 - GALEX: The Andromeda Galaxy Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. While its spiral arms stand out in visible light images of Andromeda (also known as M31), the arms look more like rings in the GALEX ultraviolet view, dominated by hot, young, massive stars
This ambitious photographic cartography of the Andromeda galaxy represents a new benchmark for precision studies of large spiral galaxies which dominate the universe's population of over 100 billion galaxies. 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
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 team also determined that it is enriched in elements much heavier than hydrogen and helium, and the only way to get these heavy elements is from exploding stars called supernovae. If the Milky Way does possess a similarly huge halo, the two galaxies' halos may be nearly touching already and quiescently merging long before the two massive galaxies collide

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
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
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
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
The faint outer parts of a spiral galaxy are more susceptible to warping because they are less strongly bound by the gravitational and other forces that keep disk stars in a plane and are also more susceptible to the influence of neighboring galaxies. In this 2010 infrared image, dust heated by newborn, massive stars are depicted in yellow and red, which trace out the spiral arms, while mature stars are colored blue (more)
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)
The irregularly edged swatch is the extent of the PHAT survey, which over 39 months took thousands of high-resolution images of Andromeda using the Hubble Space Telescope. At the winter American Astronomical Society meeting this week in Seattle, a poster of the Andromeda Galaxy welcomes astronomers to the biggest astronomy conference of the year

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

Most of all, she enjoys attending meetups; having been to two meetups thus far, she feels that they're a blast and she has always left with many happy memories! Her proudest accomplishment on wikiHow has been taking a step further in the world, i.e. 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
