This comprehensive image functions Abell 3827, a galaxy cluster that uses a wealth of amazing possibilities for research study. It was observed by Hubble in order to study dark matter, which is among the best puzzles cosmologists deal with today. The science group utilized Hubble’s Advanced Camera for Surveys (AIR CONDITIONER) and Wide Field Camera 3 (WFC3) to finish their observations. The 2 electronic cameras have various requirements and can observe various parts of the electro-magnetic spectrum, so utilizing them both enabled the astronomers to gather more total info. Abell 3827 has actually likewise been observed formerly by Hubble, due to the fact that of the fascinating gravitational lens at its core. 

Looking at this cluster of numerous galaxies, it is fantastic to remember that up until less than 100 years earlier, numerous astronomers thought that the Milky Way was the only galaxy in the Universe. The possibility of other galaxies had actually been disputed formerly, however the matter was not genuinely settled up until Edwin Hubble verified that the Great Andromeda Nebula remained in reality far too far-off to be part of the Milky Way. The Great Andromeda Nebula ended up being the Andromeda Galaxy, and astronomers acknowledged that our Universe was much, much larger than humankind had actually pictured. We can just think of how Edwin Hubble — after whom the Hubble Space Telescope was called — would have felt if he’d seen this incredible picture of Abell 3827.
