Scientists found a wave of hot gas twice the size of the Milky Way in the Perseus galaxy cluster that they believe is billions of years old. <\/p>\n
The study, which is published in the June 2017 issue of Monthly Notices of the Royal Astronomical Society, combined data from NASAs Chandra X-Ray Observatory with radio observations and computer simulations. <\/p>\n
Perseus, named after its host constellation, is 240 million light years away and is made of gas burning so hot it can only glow in X-rays. While studying the burning gas, Chandra found many interesting things, but focused on an enigmatic concave called the bay. <\/p>\n
After combining 10.4 days worth of high-resolution Chandra data with 5.8 days of wide-field observations, the team had created an X-ray image of the gas in Perseus. They then filtered the data to highlight the more subtle details and compared the enhanced image to computer simulations of merging galaxy clusters. <\/p>\n
