THE HIMIKO CLOUD
INCUPDATES |
in a Japanese Subaru field.Infrared observations with Spitzer Space Telescope show that Himiko
is as massive as several tens of billions of suns.
This nebular gas cloud is thought to be
a Protogalaxy. There have been no spectroscopic signatures of anything other than hydrogen or helium. Its light cannot
be ascribed to gravitational lensing, black holes or exterior excitation.
It is 55,000 light years across "half the diameter of our galaxy" and at the time of discovery, hold more than 10 times as much mass as the next largest object found in the early universe, or roughly
the equivalent mass of 40 billion Suns.It is first discovered by the Subaru Telescope.This object is seen when the universe was only 800 million years old, corresponding to 6% of its present age.
