Scientists Explored the Most Faraway Supernova – Brightest Cosmic Explosion


Scientists explored the most faraway supernova that has been discovered ever in history. it was the hugest as well as brightest celestial explosion known as DES16C2nm, which occurred 10.5 billion years back at the time of quarter the current age of the universe. The research has been performed by the team of international scientists from the University of Pennsylvania.

Mathew Smith from the University of Southampton has led the research in association with a postdoctoral fellow, Chris D’Andrea and an associate professor, Masao Sako from the Penn’s School of Arts and Sciences. Also a team of researchers from the University of Portsmouth contributed to the exploration.

Chris D’Andrea stated that, “What we think could be happening here is that the stellar explosion produces a magnetar at its core: a rapidly spinning neutron star with a magnetic field 100 trillion times stronger than that on Earth.”

The research team has reported that a light from the supernovae has just arrived on the Earth after travelling long since 10.5 billion years, which has made the event oldest as ever observed and explored. It is thought by the researchers that the universe must be about 13.8 billion years old at the time of occurrence of the supernova. The detailed findings obtained from the study have been revealed in the paper published by The Astrophysical Journal.

D’Andrea added that, “If we look at how the light from the superluminous supernova evolves in time, it matches very well models of the amount of energy that magnetars emit as they spin. This energy is hitting the winds of the ejected material from the stellar explosion and dramatically brightening what we’re seeing.”
