At the center of the Milky Way galaxy is a supermassive black
hole called Sagittarius A*, whose mass is four million times the
mass of the Sun, and some astronomers call it a soft giant because
of its silence. But one day he may become extremely active,
Azernews reports.
According to the researchers, they observed in real time an
amazing brightness caused by the awakening of a supermassive black
hole in the center of another galaxy from a state of rest and the
beginning of rotation along with nearby material. The roar of a
black hole was also recorded at this time.
Ground-based and orbiting telescopes were used to observe events
in the core of the galaxy SDSS1335+0728, located about 360 million
light-years away in the constellation Virgo. A light-year is the
distance that light travels in one year (9.5 trillion
kilometers).
Black holes are extremely dense objects, and their gravity is so
strong that even light cannot escape the attraction of these
giants. Their sizes range from a mass equivalent to one star to
monsters existing in the centers of many galaxies, millions or even
billions of times larger than celestial bodies. The mass of the
supermassive black hole in the galaxy SDSS1335+0728 is about a
million times the mass of the Sun.
The environment around a supermassive black hole can be
unusually "creepy" as it tears apart stars and absorbs any other
material within its gravitational pull. The researchers reported
that a rotating disk of diffuse material had formed around the
supermassive black hole SDSS1335+0728, and that some of the matter
had been depleted. This is called an accretion disk and emits
energy at very high temperatures, sometimes exceeding the
temperature of the entire galaxy.
Such a bright and compact region, powered by a supermassive
black hole in the center of the galaxy, is called the "active
galactic core." According to astrophysicist Paula Sanchez Saes of
the European Southern Observatory in Germany, these nuclei emit
large amounts of energy at wavelengths from radio to gamma rays. He
added that such nuclei are considered to be among the brightest
objects in the universe. The study of active galactic nuclei is
crucial for understanding the evolution of galaxies and the physics
of supermassive black holes.
Astronomers believe that the black hole in question is located
far enough from Earth and does not pose a threat to our planet.
