Astronomers have yet again reported another discovery from the outer space. This time, they reported that they have found what seemed to be a "ghost" of an incredibly old star -- this ancient space element is known as the remnants of what once was a supernova. They believe that this ancient star can be linked to the dawn of the universe to help scientists figure out what could possibly happen to the galaxy in the future.
"We have found a time machine that could take us back to the beginnings of the Universe. It can show us the earliest stars in the universe to help us understand why the Universe is at it is today," said Dr. Thomas Nordlander. He is the head of the ANU Research School of Astronomy and Astrophysics (RSAA).
The researchers were able to find a trace of an ancient supernova in the Milky Way galaxy. They named it the SMSS J160540.18-144323-1.
"The pattern of elements our team has found in the star has left traces of its ancestors. The dead star exploded like a supernova -- which at that time was quite freeable considering the conditions." Nordlander added. "We think that the energy of the supernova of this ancestral star must be very low because the elements fell back creating a remnant of that explosion.
Dr. Nordlander also expressed that the remnant of the star that they found in the galaxy has had its lower iron level ever measured out of the thousands of stellar discoveries each year. This also indicates that the star might have been more after the generation of fallen stars seemed to have lined up for you. "This seemingly anemic star, which was likely formed a few million years before the Big Bang theory. Its iron levels are 1.5 million times lower than that of the sun."
The ANU team found this iron-deficient star using their ANU SkyMapper and a number of 2.3-meter telescopes. The team was working from the Siding Spring Observatory in NSW. Dr. Nordlander first discovered of the star while he was in the laboratory and was observing it alone.
Professor Martin Asplund, the co-researcher in the study said that "it was unlikely that any true first start would have survived up to the present day.
"The good news is that the ancient stars can now be studied through their children's stars. The ones that came after when the team has discovered what they have discovered. In the process, the astronomers remain resolved that these discoveries and their facts have left many speechless.
