The most impressive high- res photograph of Andromeda Galaxy has been recently made public by NASA, wowing millions of astronomy fans worldwide. Andromeda is the closest spiral galaxy to our own Milky Way, and is 2.5 million light years far. The picture is of 1.5 billion pixels and is 1000 times the resolution of a normal top quality image. NASA’s new picture of Andromeda was caught by the Hubble Space Telescope and is 60,000 by 22,000 pixels. The 4.3 gigabytes photo requires 600 HD TV displays to show it all.Andromeda was particularly chosen for the venture as its less challenging to take high-definition pictures of cosmic systems that are closer to us as contrasted with the ones which are located much farther in the universe.
The Andromeda Galaxy is a twirling cosmic system more or less 2.5 million light-years from Earth in the Andromeda constellation. It is otherwise called Messier 31, M31, or NGC 224. The galaxy is frequently alluded to as the Great Andromeda Nebula in older writings. The Andromeda Galaxy is the closest spiraling cosmic system to our Milky Way, yet not the closest galaxy in general.
Andromeda gets its name from the sky area in which it shows up — the constellation of Andromeda. It was named after the mythological goddess Andromeda. The Galaxy is the biggest cosmic system of the Local Group, which additionally contains the Milky Way, the Triangulum Galaxy, and around 44 other littler galaxies. The 2006 data collected by the Spitzer Space Telescope uncovered that M31 counts one trillion stars, which is probably double the quantity of stars in the Milky Way, which are gauged to be 200–400 billion.
The photo was caught by the scientists from the University of Washington. It sets a new standard for accuracy investigations of huge spiral cosmic systems. It took three years for the expert to come up with the image. The researchers used 7,398 different frames taken from 411 angles to make the extremely detailed panorama.
The top notch picture was discharged at the 225th gathering of the American Astronomical Society this January. The photo is detailed to the point that it shows each star present in the cosmic system as an individual dot of light. Of course, many are fascinated by the possibility of one or more of the lighted dots being similar to planet Earth and hosting life-forms. An animated feature of the image is also available on YouTube.
Space experts project that Andromeda and the Milky Way will eventually merge in two billion years from now and result in an elliptical galaxy. The two cosmic systems are so similar that most books have been known to display the pictures of the Andromeda to show how the Milky Way looks. That is because for the time being it is virtually impossible to get such an all encompassing picture of the Milky Way.
