The gas cloud, which was discovered from a distance of 12.9 billion light-years, could indicate the early phases of galaxy formation when the universe was only 800 million years old.
Himiko is a massive galaxy with a 55,000-light-year-long hot incandescent gaseous halo. Himiko is not only massive, but also extremely distant, having been discovered around 800 million years after the Big Bang, when the universe was only 6% of its current size and stars and galaxies were barely forming. It is so old that elements like carbon are almost non-existent from its elements. There has been no data found regarding the elements it consists, of other than hydrogen and helium.
