Galaxies of a feather flock collectively, and typically they flip into infernos. It would possibly appear to be a 1960s sci-fi TV present particular impact, however a colourful new picture of a galaxy cluster reveals a “cosmic furnace” and has caught the attention of European Space Agency scientists.
A galaxy cluster is precisely what it feels like: a group that may include 1000’s of galaxies. In this wild picture, sub-clusters of galaxies (seen in bluish-purple) are colliding into one another, ramping up the temperature of the gases round them in a course of referred to as “shock heating.”
Normally, these gases are about 2.7 times hotter than our sun’s core, however this cluster is feeling the warmth at 25 times hotter than the core of the solar, ESA mentioned in assertion on Thursday.
It took a posh collective effort — from ESA’s XMM-Newton X-ray Observatory, the National Astronomical Observatory of Japan’s Subaru Telescope (which sees in optical-infrared) and the Green Bank Telescope (which picks up radio emissions) — to create the exceptional picture.
The colours spotlight the options inside the cluster. Orange marks particular person galaxies. Gases present up in inexperienced (scorching and dense) and pink (scorching and skinny). The spots the place inexperienced modifications to pink point out the place the brutal heating course of is occurring.
“The international collaboration of the scientists, instruments, and datasets has captured this new and exciting aspect of structure formation,” the Green Bank Observatory mentioned in a press release.
We haven’t got to fear about getting burned the place we’re. The galaxy cluster, named HSC J023336-053022 (XLSSC 105), is 4 billion light-years from Earth. Whew.
