Recording the universe of youth

The photograph of the explosion of a star nearly 13 billion years ago, has just been claimed to be the oldest image of the universe "falling" at the present time.

The beam of creativity created by the photograph named GRB 090423, of the gamma wavelength, is thought to have begun its cosmic journey after the Bigbang explosion of about 630 million years.

Thus, the star emits a light beam of the first class of celestial bodies that appear after the universe is formed. Details of the photo are published in the UK's prestigious scientific journal Nature.

Through gamma ray telescopes and measured by the "red shift" method, the team discovered a beam of light with increasing wavelength, corresponding to the expansion of the cosmic phenomenon, thereby measuring the duration of the of light. "Red shift" is a measurement method similar to the Doppler effect, which helps scientists calculate information about sound sources in a moving state.

Here, instead of calculating the velocity and distance of the sound source, the scientists calculated the distance and wavelength of the light source (the star exploded, emitting this gamma beam).

GRB 090423 was discovered by NASA's Swift satellite from April 23. Dr Dale Frail, who works at the National Radio Astronomical Observatory in Socorro, New Mexico, USA, said: "The explosion of GRB 090423 provides an unprecedented view of the boyhood universe. " . He said that through analysis of GRB 090423, early stars of the pillar were bright, hot, and contained more material than current stars.
