The spiral galaxy, called Speca, throws fast-moving jets of particles from the center, a phenomenon particularly spotted in elliptical galaxies. In fact, Speca is the second spiral galaxy in the universe known to feature such jets.
These jets are thrown outwards by a supermassive black hole located at the core of the galaxy. Scientists hope that the study of Speca galaxy will brings new information about black holes, the birth of stars and the interaction between the two.
Speca is 1.7 billion light years away from Earth. Apart from its spiral pattern, it resembles also a radio galaxy.
In the center of a radio galaxy is a supermassive black hole. The surrounding matter is “thrown” outwards, forming bright streams that generate radio waves.
Most of the detected radio galaxies are elliptical. They are old, with no new stars, while the spiral galaxies reveal more star birthings. Therefore, according to the scientists, the discovery of spiral radio galaxy is very challenging. Research on speca could help astronomers to learn how a spiral galaxy transform into an elliptical one.
