Powerful ‘Fast Radio Burst’ Travels 8 Billion Years: Remarkable Discovery by Astronomers

Astronomers have made a groundbreaking discovery by detecting an incredibly brief flash of radio waves known as a fast radio burst (FRB) that originated eight billion years ago in deep space. This remarkable burst of energy, which was more than three times stronger than previously thought possible, is not only the oldest FRB ever observed but also sheds light on our understanding of the universe’s early history. These findings, reported in October’s edition of Science, have sparked great excitement among the scientific community.

The fast radio burst lasted only a few milliseconds, yet it contained an astonishing amount of energy equivalent to 30 years’ worth of solar emissions. This extraordinary phenomenon provides a valuable opportunity to study the intergalactic medium and its impact on the space between galaxies. Macquarie University, in a statement, notes that fast radio bursts offer a unique way to measure properties and gain insights into the matter distribution in the universe.

Since the detection of the first FRB in 2007, astronomers have identified approximately 800 more of these elusive radio signals. However, the exact cause of fast radio bursts remains a mystery. Researchers suspect that magnetars, a type of neutron star with a powerful magnetic field, may be responsible for producing these extreme bursts. Neutron stars are the remnants of massive stars that have exploded, leaving behind highly dense objects with extraordinary properties.

For this recent detection, scientists utilized the Australian Square Kilometer Array Pathfinder (ASKAP), a radio telescope consisting of 36 dishes located in Western Australia. ASKAP accurately determined the origin of the burst, allowing the researchers to subsequently use the Very Large Telescope in Chile to precisely locate the source galaxy. This galaxy, though somewhat indistinct in the images, appears to be the result of a collision between multiple galaxies in the early universe.

Further investigations using FRBs aim to ascertain the amount of plasma, specifically hot and diffuse gas, present between galaxies. As fast radio bursts pass through intergalactic particles, they disperse, enabling astronomers to measure the dispersal and calculate the quantity of plasma between Earth and the point of origin of the burst. This knowledge will contribute to a better understanding of the universe’s evolution and the distribution of matter within it.
