Astronomers have created a new way to see through haze Universe Observing the birth of these objects has always been a goal of scientists because it will help explain how the universe evolved from the vacuum after the phenomenon of the Big Bang that started the universe until the complex picture that we observe today, after 13.8 billion years.
It’s something assigned to the new James Webb Space Telescope, as well as the Square Kilometer Array (SKA), according to the British newspaper, Daily Mail.
But as Webb looks at wavelengths in the infrared, the next generation of SKA’s Earth-based telescope, due to be completed by the end of the decade, will study the early universe through radio waves.
Also, for current radio telescopes, the challenge is to detect the cosmic signal of the stars by pulling away the thick hydrogen layer, which obscures the view because it absorbs light well.
Distortion from other radio signals can also get in the way, which is one of the severe challenges facing modern radio cosmology.
But researchers led by the University of Cambridge have now developed a new methodology, using mathematics, that will allow them to see primordial clouds and other sky-noise signals, so it will allow them to avoid the harmful effect of distortions caused by a radio telescope.
Their idea, which was part of the REACH (Radio Experiment for Analyzing Cosmic Hydrogen) experiment, will allow astronomers to observe the oldest stars by their interaction with hydrogen clouds, in the same way we would infer a landscape by looking at shadows.
Perhaps the hope is that this will improve the quality and reliability of observations from radio telescopes looking at this key undiscovered time in the evolution of the universe, with the first observations expected from REACH later this year.
