Compared to the numbers of galaxies that we know of (hundreds of billions), blue-shifted galaxies are seemingly quite rare. However, the light coming from the Andromeda galaxy has a BLUE shift, which indicates motion towards us. Plus, get FREE SHIPPING & BONUS GIFT! Yes, galaxies do move. an area of space that got just enough galaxies around that it actually pulls neighbors around. For example, I have learned from my research that the Milky Way and Andromeda galaxy are approaching each other with a speed of about 130 km/s, however the collision of these two galaxies will not occur for about 5 billion years (AstroFile). Watch more videos for more knowledge Why Is Andromeda Coming Towards Us? In addition, our solar system–Earth and all–whirls around the center of our galaxy at some 220 kilometers per second, or 490,000 miles per hour. Andromeda is an exception to the rule, however, and is moving toward the Milky Way at about 250,000 miles per hour. Fortunately, a galaxy is much heftier than a photon, and it is not flying toward us at the speed of light, so we have a little more than 2.5 million years to prepare. Ants are constantly, How dangerous is pest control? Not all astronomers think this (Halton Arp is one who disagrees), but most do. In Greek mythology, Andromeda was the daughter of Cepheus and Cassiopeia, king and queen of the African kingdom of Aethiopia. Milky Way Has 4 Billion Years to Live — But Our Sun Will Survive. Thanked: 3 times; Extropian by choice! If we assume Andromeda has been moving at the same speed without accelerating, then in the last 2.5 million years, Andromeda has moved only 900 light-years closer to us. College Park, Maryland. The Andromeda Galaxy is approaching the Milky Way at about 110 kilometres per second (68 mi/s) as indicated by blueshift.However, the lateral speed (measured as proper motion) is very difficult to measure with a precision to draw reasonable conclusions: a lateral speed of only 7.7 km/s would mean that the Andromeda Galaxy is moving toward a point 177,800 light-years to … Question: What Things Fail A Home Inspection? Based on Doppler shifting of its light, Andromeda is speeding toward us at 68 miles per second (110 kilometers per second). A: Ever since we could measure the movement of Andromeda, we’ve known it was on a collision course with the Milky Way. Question: What Is The Most Expensive China? Systems Group,   It is an intrinsic expansion whereby the scale of space itself changes. In 1912 Vesto M. Slipher finally managed to measure the spectrum of the Andromeda galaxy. Some chemicals are known, Do bed bugs have a natural enemy? Quick Answer: What Should You Not Put In A Dishwasher? Unless something radically changes Andromeda’s course, current estimates say that we’re only about 4 billion years from a catastrophic collision that will leave us inside a merged remnant of what was once two separate galaxies. Most astronomers think that the red shift we see from other galaxies is evidence that the universe is expanding. 21 things you should, Do termites fly around at night? How Long Does It Take For Clay To Get Bone Dry? Andromeda is not the only galaxy to be moving towards us. How come Andromeda is moving towards us? Valerie Mikles   The observable universe can be thought of as a sphere that extends outwards from any observation point for 46.5 billion light years, going farther back in time and more redshifted the more distant away one looks. How come Andromeda is moving towards us? This artist’s concept shows the night sky from Earth in 3.75 billion years: Andromeda is much closer, appears larger, and has begun to distort the plane of the Milky Way with its gravitational pull. Currently, Andromeda and the Milky Way are about 2.5 million light-years apart. Wouldn’t its actual position be 2.5 million light-years closer, and shouldn’t it be colliding with our galaxy now? is falling towards us exactly as fast as it's being carried away by the expansion of the Universe. The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between two galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy. Some stars will be ejected from the resulting galaxy, nicknamed Milkomeda or Milkdromeda. It is a cluster of galaxies some 50–60 million light years from here, moving away from us at nearly a thousand kilometers per second.

Galaxies are also moving away from each other due to the expansion of the Universe brought on by the Big Bang. ... We can tell from a galaxy’s spectrum if it is moving away or towards us and how fast it is moving by using the Doppler effect. The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs). National Oceanic and Atmospheric Administration Contractor,   In the 1920's, Edwin Hubble and others observed that most galaxies appear to be rushing away from us, which led to the discovery that the Universe is expanding. Quality Assurance, I.M. The galaxies as we know them will not survive. The Solar System is traveling at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph) within its trajectory around the galactic center, a speed at which an object could circumnavigate the Earth’s equator in 2 minutes and 54 seconds; that speed corresponds to approximately 1/1300 of the speed of light. So how much closer to collision with Andromeda have we come in the past 2.5 million years? Based on Doppler shifting of its light, Andromeda is speeding toward us at 68 miles per second (110 kilometers per second). Technically, neither space nor objects in space move. “The reason that we see Andromeda moving toward us is because it’s nearby enough, and the Milky Way is massive enough and Andromeda is massive enough … Things moving away from us have light that is Doppler shifted toward the red end of the spectrum; things moving toward us have light shifted toward the blue. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour. NASA, ESA, Z. Levay and R. van der Marel/STScI, T. Hallas, and A.
