The 17th century event, which kept famous astronomers like Hevelius and Cassini wondering, has been explained by the scientists. According to the accounts of Hevelius, he classified the explosion in skies as a new star.
The 350 year old question has been answered by scientists in a released video, which contains footage from the Southern European Observatory, located in the Germany. Rare and violent explosion occurred in 1670. The event was visible to the naked eye but scientists were unable to find any clues and traces since years despite possessing modern technology and sub millimeter telescopes.
The initial claims said that the object can be a nova or white dwarf which exploded in outer space but detailed study has reveal that it is a type of stellar object. The object vanished few years ago but during its two appearances it showed different amount of the brightness.
The scientists in 1980s declared the object as a faint nebula because of the low technological advancement during that period. The Nova vul 1670 is confirmed to be a stellar object now and astronomers informed that most novas occurred due to explosion of the binary stars; the nova vul 1670 doesn’t fit in this category..
The Atacam Pathfinder Experiment (APEX) telescope was used primarily during the research along with the Effelsberg Radio telescope, which determined the chemical composition of the distant object and identified isotopes of the gases present.
The findings of this research activity are printed in ‘Nature’, a science journal by Tomasz Kaminski.
