Research Supports Idea of Galaxy Grew from Inside-Out
In a breakthrough revelation, it has been unveiled that there is a way by which it can be determined that how quickly different parts of the Milky Way have formed. In order to do so, astronomers require monitoring the fast-produced elements like magnesium.
It has been suggested by researchers that stars in the inner region of the Milky Way's disc was formed first. This has acted as a support for existing ideas that Galaxy might have formed from inside-out.
In order to reach at the above mentioned conclusion, an international team of scientists have used data from the 8-m VLT in Chile, which is accredited as one of the world's largest telescopes.
Main aim of the researchers was to study stars in detail that varied in ages and locations in the Galactic disc. By observing the same, the astronomers wanted to know about metallicity, which is amount of chemical elements that are present in a star other than hydrogen and helium.
It shall be noted that older stars do not have many elements in their makeup and will be having lower metallicity. Lead investigator on the on the Gaia-ESO Project, Professor Gerry Gilmore, said that stars present in the outer regions of the Galactic disc are younger. They have low magnesium levels than their metallicity.
"We have been able to shed new light on the timescale of chemical enrichment across the Milky Way disc, showing that outer regions of the disc take a much longer time to form", said leader of the study, Maria Bergemann from Cambridge's Institute of Astronomy.

During the last two days there have been two incidents of shark attacks which caused the media to start a frenzy of `Jaws' but if you see by numbers then the sharks are more at risk of being extinct since every year humans kill around 100 million of them.
A study conducted over 20 years back in the making discovered that 25 percent of all shark and ray species have the danger of being extinct in the next few decades. New studies of the water bodies on our planet explains that in the coming days there is very little hope for Earth's shark and ray populations.
A team from the International Union for the Conservation of Nature, which is the world's largest and oldest global environmental network maintaining a "Red List" of threatened species, kept a record of the count of sharks left in our seas along with the reason of their numbers getting lower every year.
The findings of their study shows that overfishing, along with a demand for shark fin soup and hunting killer sharks due to human fear are the main reasons behind shark and ray populations to reduce.
