3 percent


According to the Astronomy magazine article entitled Great observatories find candidate for most distant galaxy, a newly discovered galaxy, detected with the Hubble and Spitzer telescopes, has set the record for distance. It is 13.3 billion light-years away.

The current predicted age of the Universe is 13.7 billion.

That puts this galaxy's age at around 420 million years after the Big Bang.

And that's 3% of the age of our Universe.

And that's, just... wow.

And, and! It's small. 600 light-years wide. The Large Magellanic Cloud near our Milky Way is 2000.

This could mean it is one of the first galaxies. Or building blocks for another galaxies. That it may have merged and remerged with other nearby objects.

This is very interesting on many levels. But perhaps the most interesting is just what we're able to coax out of these telescopes. Makes one wonder what we'll be able to do with bigger mirrors!
