The spiral galaxy M91 hit the lens of the Hubble Space Telescope. Located in the direction of the constellation Berenice, about 55 million light-years from us. As can be seen in the photo, it is called barred spiral galaxy, or galaxy, whose nucleus is crossed by a strip of stars and interstellar matter.
While the central, distinctive part of the M91 is quite impressive, there are also astronomical monsters hidden there. Like our galaxy, there is a supermassive black hole in the middle of M91. According to a 2009 study by Hubble Archival Data, 9.6 to 38 million solar masses accumulate in its central black hole.
According to Hubble archival data, astronomers determined the mass of its central black hole, and the new observations had a different scientific purpose. The purpose of this observation program is to collect data that can be used to determine the relationship between young stars and the cold gas clouds in which they are born.
To do this, astronomers used Hubble to observe ultraviolet and visible galaxies already studied in the radio range by the Atacama Wide Millimeter / Submillimeter Telescope (ALMA).
Hubble observation is the most valuable and valuable resource for astronomers. To obtain data from a telescope, astronomers must first make a proposal in which they must describe the scientific significance of these observations.
After that, the proposal becomes anonymous and its scientific value is assessed by many different astronomical experts. This process is highly competitive: in recent years, only about 13 percent of Hubble observation requests have been allocated time for observation.
