The halo that surrounds the Milky Way is much hotter than scientists once thought. They think this may be a ubiquitous characteristic of galaxies after examining the data.
The collection of dust, gas and dark matter, looking a bit like a fog to the naked eye, that surrounds some galaxies, is know as a “halo.” And the Milky Way’s Halo is at least ten times hotter than once thought.
While previous research revealed that extreme temperatures (up to 18 million degrees Fahrenheit) could be found not just in certain parts of the halo, but that this may be the average temperature of the entire halo.
Researchers said that this piece of information could help scientists understand how the Milk Way galaxy and others like were created and how they grow.
The new data the analyzed came from an X-ray observatory telescope. This one one run by the European Space Agency. It is called the XMM-Newton. The telescope collects data in X-rays that normally would be blocked out by the Earth’s atmosphere.
The new data about the halo, which scientists consider the “link” between a galaxy and the wider universe, could help scientists understand how such a galaxy changes and interacts with the space around it over time.
