Asteroid, Space, Remnants

In a new study, which was published in the journal Nature, in which an international team consisting of astronomers who are depending on the indirect evidence and are searching the signatures of the oxygen and helium which are believed to be created in the cores of the stars.

As per the reports of the Forbes, the current generation Hubble Space Telescope is not just equipped with instruments which help to see into the deepest depths of the space and time. The oldest and farthest galaxy ever detected is GNZ-11, and it is formed 400 million years after the Big Bang. The scientist who is studying this galaxy said that the stars started to flicker sometime between 380,000 years after the Big Bang.

As per Amos, the researchers now turned their eyes to the galaxy MACS1149-JD1, which is lying about billions of light years away. This was discovered by using the two Earth-bound telescopes which are the Atacama Large Millimetre/Submillimetre Array (Alma) and the European Southern Observatory’s Very Large Telescope (VLT).

The expansion of the universe shifts that light and by analysing the shift. The researchers have figured out the age of the oxygen and a hydrogen signature despite it is not seen directly in the galaxy.

According to the Richard Ellis, who is the professor of astrophysics at University College London and also the co-author of the study said, “Oxygen has a redshift of 9.1 that means the Universe has expanded nine to 10 times since the light left this object. We’re looking back about 97 percent of the way to the Big Bang [13.8 billion years ago] when the Universe was only about 500 million years old.”

As per the press release, the team of researchers has used the infrared spectroscopy from NASA’s Spitzer and Hubble Space Telescope to look at the brightness of JD1. They have used the brightness to develop the model of the star and calculate the age of the stars in JD1.
