An international team of astronomers led by staff of the Space Research Laboratory is a very rare discovery that is of great astrophysic importance.
The planetary nebula itself is called the IPHASX J055226.2+323724. This is the third time that scientists find an object of this type in a scattered cluster. In all, some 4,000 planetary nebula have been found in the Milky Way. In addition, IPHASX J055226.2+323724 is the oldest object ever found.
The authors of the study found that the kinematic age of nebula is 70000 years. In their assessment, scientists relied on how fast it expands, and also studied its mission lines. From the point of view of the life of the star from which the planetary nebula emerged, it is a moment. It has lived hundreds of millions of years, scientists report.
Also during observation and analysis, scientists discovered that IPHASX J055226.2+323724 is from a cluster that is almost half a billion years old.
Remember, planetary nebula is an astronomical object that is a shell of ionized gas around a central star, a white dwarf, formed by the release of the outer layers of a red giant or supergiant with a mass of between 0.8 and 8 solars at the end of the evolution of the object.
