A floating part of the Big Bang might reveal new things about stars and galaxies creation.
Professor Michael Murphy from the Swinburne University of Technology, Australia along with Ph.D. student Fred Robert has found a fossil cloud in the space that can take us to the Big Bang. As per the researchers, the cloud irradiates a specific radiance of materials that are falling into a black hole.
According to Robert, they have aimed the same quasars where previous researchers in the lower-quality spectra have found shadows from the hydrogen and not from the heavy elements. This known target allowed researchers to find such rare fossil using Keck Observatory’s twin telescopes. Quasars are gigantic and extremely distant celestial objects.
The researchers have used the world’s most powerful optical telescope which is placed at the W. M. Keck Observatory in Hawaii.
The cloud discovered is unique when compared to other gas clouds in the universe, as this cloud is free from metals. It is assumed that this cloud has accumulated 1.5 billion years of knowledge and from then it has hardly changed. Robert added that the possibility of finding heavy metals inside this cloud is very less. It is less than 1/10000th of the proportion we see in the sun, which is really small. This is the most convincing description to prove the cloud as the remnant of the Big Bang. Since its inception, the cloud has not been polluted by star explosions and this shows its uniqueness.
The researchers have not disclosed much about the findings. The details will be shared in the Royal Astronomical Society journal.
The first fossil cloud was discovered in the year 2011. The current is the third discovered fossil cloud. Professor Michele Fumagalli discovered the first fossil cloud and the second fossil cloud was discovered by John O’Meara.
