A new study found that massive explosion The previously unknown in deep space, which occurred nearly 13 billion years ago, is the first evidence of a mysterious type of star. This may be the reason why a star is contained in Milky Way Galaxy, known as SMS J200322.54-114203.3, on metallic elements such as zinc, uranium and possibly gold, more than other stars of the same age.
According to the British newspaper, “Daily Mail”, these minerals usually consist of merging neutron stars, but not at the levels that appear inSMS J200322.54-114203.3.It is about 7,500 light-years away from the Sun.
Also, through the new study, it is believed that first stars The universe, which was almost entirely filled with hydrogen and helium, collapsed and exploded shortly after formation, giving rise to neutron stars or black holes that produced heavier elements for the next generation of stars..
“The extra amounts of these elements have to be from somewhere,” said study co-author Chiaki Kobayashi, assistant professor at the University of Hertfordshire.“.
“We have now found observational evidence for the first time that directly points to a different type of hyperexpansion producing all the stable elements in the periodic table simultaneously,” the researcher added.
Researchers used استخدم SkyMapper and telescope ANU 2.3 meter in observatory spring siding The star was first identified, and later confirmed by more detailed observations with the 8-meter European Southern Telescope in Chile..
