Sky Bubbles Mysterious Age 12.9 Billion Years

A mysterious object recorded most remote in space. The call astronomy as primordial bubbles that are named Himiko, a name taken from the Kingdom of Japan's ancient queen who was also the same mysterious.

So called because the object is a giant form not long after the universe form the beginning of the explosion (Big Bang). Size is very large, in the form of the mass of gas 40 billion times the mass and the sun and a half times the diameter galaxy Bima Sakti.

Very old age is about 12.9 billion light years (light year is equivalent to 9.5 trillion kilometers). Himiko structure that was not able to give descriptions of early galaxy formation when the universe is still very young and the new age of around 800 million years.

"I had never heard the other kind of object that this far in the distance," said Masami Ouchi, researchers from the Carnegie Institution, California, USA. Objects may be similar bubble Lyman-Alpha that between 2-3 billion years.

Himiko form at the end of the epic that ionization takes place between 200 million and one billion years since the Big Bang. At that time, the universe just a new form of birth and the stars and the galaxy.

Shaped like a gas bubble may form terionisasi that beset supermasif giant black hole or a collection of cold gas. However, it can be Himiko is the result of the collision of two galaxy ignites young, single giant galaxy, or the location of the formation of stars that are very active.

Himiko was first recorded using the Subaru telescope in Hawaii in 2007. Ouchi and his team then conducted more carefully using the instrument spektrografi Keck / DEIMOS and Magellan / IMACS. From observation, the uterus was detected hydrogen ionization, the distance, and age of an object is mysterious.

"We plan to make infrared observations with Hubble space telescope to make sure, if there are characteristics merging objects or not," says Ouchi. However, it can be repaired Hubble after the flight mission in NASA aircraft that Atlantis is scheduled next month.
