The Most Detailed Age Map of the Milky Way Has Been Created And It Will Allow Astronomers To Further Understand Our Galaxy

Our own galaxy, the Milky Way, has been widely studied by scientists and is still under a lot of study. Astronomers accept now created something that looks cute, it is the nigh detailed 'age map' of the Milky Way always created. This age map was created afterward the astronomers identified the ages of over 130,000 different stars. An age map like this tin aid the astronomers sympathise our universe much amend. The astronomers can understand how over the course of 13.v billion years our galaxy has grown through the accumulation of stars and gases, using this new historic period map.

"We haven't previously known much about the historic period of the about ancient component of the Milky Manner, which is the Halo System," said one of the team, Daniela Carollo, from the Academy of Notre Matriarch

"But at present we accept demonstrated conclusively for the first time that ancient stars are in the center of the galaxy and the younger stars are found at longer distances. This is another slice of information that we tin apply to understand the assembly process of the milky way, and how galaxies in full general formed."

This detailed age map of the Milky Fashion will let astronomers larn more most our milky way

The detailed map was created using data that was gathered by the Sloan Digital Sky Survey – the information was in search of helium-called-for horizontal-co-operative stars, whose ages are based on their colors.

"The colours, when the stars are at that stage of their evolution, are directly related to the amount of time that star has been alive, so nosotros can estimate the historic period," said team member Timothy Beers.

The team somewhen managed to detect more than 130,000 of these horizontal-branch stars and plotted them. The three-dimensional plot that came about shows that older stars are more likely in the centre of the galaxy while the younger ones are in the outskirts.

"In one case you lot have a map, then you can determine which stars came in get-go and the ages of those portions of the milky way," Beers said.

"Nosotros can at present really visualise how our galaxy was built up and inspect the stellar debris from some of the other small galaxies being destroyed by their interaction with ours during its assembly."

These findings show everything astronomers need to know nearly the formation of the Milky Mode. They got to know that firstly helium and hydrogen formed stars initially. After this the gravitational pull of these initial stars pulled in more and more grit and our Milky Way grew bigger. Time passed and more stars and grit clouds accumulated and were pulled past the gravitational pull, finally they combined into large structures.

The squad at present wants to map other galaxies besides, equally soon equally data from the James Webb Telescope (which NASA will launch in 2022) comes to them. Yous tin discover their published work in Nature Physics. Go along in mind this is not the starting time time a feat like this has been performed. Back in July this twelvemonth, an international team of astronomers created a 3D map that showed the position of 1.2 1000000 different galaxies. This is what that map looked like:
