In some cities you can find amazing and beautiful fountains that shine at night and organize a show. However, even the most famous terrestrial fountains can not bear with cosmic wonders.
In the vastness of the universe, it is possible to find delightful gas fountains in the centers of clusters of galaxies. One of these can be seen in the cluster of Abell 2597. This is a truly amazing sight: a huge amount of gas falls into a supermassive black hole, where a combination of gravitational and electromagnetic forces sprays most of the gas from a black hole in a continuous cycle that lasts tens of millions of years.
The researchers used data from the ALMA submillimeter array, the MUSE spectroscope on the Very Large Telescope and the Chandra X-ray Observatory. This made it possible to find the first clear evidence of the simultaneous entry and release of a gas stream activated by a supermassive black hole.
