In the known universe since the Big Bang event (13.5 billion years ago), astronomers believe that there are at least 2 trillion – that’s 2,000 billion – galaxies in the cosmic soup. From Persians to the Hubble. Is that still a definite possibility? You can also find the Andromeda galaxy by star-hopping from the star Alpheratz in the Great Square of Pegasus. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says. The large square pattern above is the Great Square in the constellation Pegasus. Remember, though, that the Andromeda Galaxy is 2.2 million light-years away, with a single light-year being almost 10 trillion kilometers (6 trillion miles). Located high in the northeastern sky around 9 p.m. Arizona time, the Andromeda Galaxy fits right into the ancient constellation of Andromeda, the daughter of Cassiopeia and Cepheus. It is found 2.5 million light-years away from our solar system. Here on Earth and in Arizona, we get to view one of the most amazing galactic objects known to mankind – the great Andromeda Galaxy. The stars involved are sufficiently far apart that it is improbable that any of them will individually collide. Best of luck viewing the Andromeda Galaxy! Here on Earth and Arizona we see the great Andromeda Galaxy, one of the most amazing galaxies known to mankind. Introduction: The Andromeda Galaxy is also known as “M31” and is a spiral galaxy and the closest neighboring galaxy to our Milky Way. Locating the Galaxy Go away from the lights of the city. Plus when galaxies collide, they don’t exactly destroy each other. Check out this cool video: Night sky as Milky Way and Andromeda galaxies merge. An imaginary line drawn through these two stars points to the Andromeda galaxy. He described the object as a “nebulous smear.”. Imagine viewing this object with just your naked eye – 2.5 million light years distant. The true size of the galaxy in terms of its angular diameter is even more impressive. First observed with the naked eye, around 964 A.D., by Persian astronomer Abd al-Rahman al-Sufi. With the eye, or with binoculars, or even with a backyard telescope, the Andromeda galaxy won’t look like the image below. Most people find the galaxy by star-hopping from a very noticeable M- or W-shaped pattern on the sky’s dome – visible in the northeast in the evening now from the northern half of the globe – the constellation Cassiopeia the Queen. What could be easier? Any light pollution can make it difficult to … It’s an island of stars in space, much like our Milky Way. Draw an imaginary line from the star Kappa Cassiopeiae (abbreviated Kappa) through the star Schedar, then go about 3 times the Kappa-Schedar distance to locate the Andromeda galaxy (Messier 31). It is about 2.5 million light-years from Earth. On Dec. 15, 1612, the Andromeda galaxy was seen through a telescope for the first time by a German astronomer named Simon Marius. Examples include the following: Literature. So although it does appear that this galaxy is approaching our Milky Way galaxy … it’s nothing to lose sleep over. Of variation many options the visit them there a block. After that, astronomers believed for some decades that the galaxy was approaching at nearly 200 miles per second (300 km/s), but later astronomers disagreed. This is just how far the bubble of gas extends from the Andromeda Galaxy. For binocular astronomers: Binoculars, as always, enhance the view. His result placed the Andromeda Nebula far outside our galaxy at a distance of about 450 kpc (1,500 kly). From as early as 1612, Andromeda galaxy had been discovered by astronomers although they assumed it was part of the Milky Way galaxy. The galaxy will appear as a fuzzy patch to the eye. However, the good news is that it’s visible all year round from the UK. View larger. If that doesn’t work for you, try sweeping the area with your binoculars.
