Every 16 years, an asterisk known as S2, from the Constellation Sagittarius, has been scratched from a mysterious object, right in our galactic center, 26,000 light years from Earth, weighing anything like 4 million suns. But this year, we were offered a unique opportunity for astronomical teams trying to Prove its existence: For several months, the "little" star approached the galactic center, allowing them to better analyze gravity behavior in extreme conditions and earn an important thread on this mega object.
In this case, it was a team that led to the collaboration between Vietnamese and Chilean researchers led by Reinhard Jensel of the Max Planck Institute to achieve "luck." It has been able to gather what it classifies as the strongest evidence of the supermasive black hole so far: every after about 45 minutes, the gaseous clouds appear to be orbital galactic center, making a full revolution of about 240 million kilometers at a speed equivalent to nearly 30% of the light speed. In the case of astrophysics, this behavior can only be explained by the presence of excessive black holes.
Last week's publication Astronomy and Astrophysics, The Genzel team points out that it's as close as always when you're seeing a zone that is directly in this type of black hole.
In addition to being convinced about the existence of this black hole in the Milky Way center, astronomers believe that at least the largest galaxy's center has large tubes.
To confirm this, it will be an explanation of the violent and spectacular phenomena that appear in the galactic centers.
