Here’s What The Night Sky Would Have Looked Like 10 Billion Years Ago

Our sun has only been around for 4.5 billion age — which mean it miss the cute other years of the Milky Way galaxy . If you were standing on a satellite 10 billion years ago , when the milklike Way was relatively young , the night sky would have look very different .

The above look-alike is an artist ’s impression of the dark sky on a planet in a young milklike Way - type galaxy , the room ours was 10 billion years ago . you’re able to see “ the sky are ablaze with star birth . Pink swarm of gas harbor new-sprung principal , and bluish - clean , vernal star cluster litter the landscape , ” asNASA explains .

A new view of young beetleweed like our own shows that as these galaxies slow down make stars , they also turn back develop as quickly in general . Which makes sense . NASA explain :

stargazer do n’t have baby delineation of our Milky Way ’s formative year to trace the history of stellar emergence so they examine galaxies standardised in lot to our Milky Way , found in recondite study of the universe . The farther into the universe astronomers look , the further back in time they are hear , because starlight from long ago is just arriving at Earth now . From those surveys , stretching back in time more than 10 billion days , researchers gather an album of images hold in intimately 2,000 snapshots of Milky way of life - like galaxies .

The new census provides the most gross picture yet of how galaxies like the Milky Way grew over the retiring 10 billion years into today ’s purple spiral beetleweed . The multi - wavelength study spans ultraviolet to far - infrared lightness , combining observations from NASA ’s Hubble and Spitzer space telescope , the European Space Agency ’s Herschel Space Observatory , and ground - based telescope , including the Magellan Baade Telescope at the Las Campanas Observatory in Chile .

Here ’s a choice of Hubble Space Telescope snap , showing how galaxy similar to our own develop over sentence :
