Hubble Extreme Deep Field

in #science7 years ago (edited)

This is a picture of some of the earliest galaxies we have ever seen.

This picture was created using Hubble telescope data from 2003 and 2004. It took multiple hours just to get enough light to produce an image. Even though this picture is of an area a “small fraction” of the angular diameter of the moon, it contains over 5500 galaxies. The picture goes as far back as 13.2 billion years, only 500 million years after the big bang. [1]

These early galaxies were most likely filled with population three and population two stars. Population three stars had very low metal content because the first metals were produced in them. Population two stars have metal, but still less than stars being formed today. With less metal stars were able to get many times larger than they are today. I even made a post on population three stars here.

testing

almost figured out where it isn't working

this should give me the specific error

Am I the error? ;)

wait what did it work or is that streemian

edit: it didn't work :(

wow I didn't expect 1% votes to give me this much

You are a big whale ^^

and the trail seems to work :)

no its streemian, the other trail doesn't seem to be working

Very nice post! Thank you for sharing!

Thanks again for the daily astronomy class.

Not testing anything.

I can't wait till they turn on the James Webb, apparently 100x more powerful than Hubble . . mind = blown!

yeah that will be cool.

either way though some of these pictures by the hubble can already take up a few gigabytes.

It will indeed; oh btw I've included you in this week's Steemlight, enjoy!
