In 2007, scientists at the University of West Virginia began observing an unusual explosion of space waves. Since then, this rapid radio explosion, or FRB, has been a mystery to astronomers.
They only knew that FRBs were radio waves and came from space within our galaxy, the Milky Way, and other galaxies.
Researchers recently identified the FRB, first acquired in 2019 with the world’s largest single-satellite radio telescope, FAST. It is located in Guizhou Province in China. FRB was extensively studied using the VLA telescope in the U.S. state of New Mexico. The FRB is still a tiny galaxy, almost 3 billion light-years from Earth, and a light-year is the distance light travels in one year.
Scientists believe that extras could cause this rapid radio explosion. These could include unusual types of stars, such as neutron stars. A neutron star is the center of a giant star at the end of its life cycle that explodes like a supernova. Another magnetar is a neutron star with a powerful magnetic field. And another possible cause of FRB is a black hole that eats a nearby star.
Casey Law is an astronomer at the California Institute of Technology. He was co-author of the latest FRB study for 2019 published in Melo. He said the FRBs are the fastest light of the radio power that turns on and off for only a millisecond second. They can be seen all over the world. Some items produce a recurring FRB storm, while others explode only once.
The 2019 FRB is repeating itself. The delicate radio signals continue in the middle of the explosion, so they seem to remain “open.” Many well-known FRBs, about 500 of them, do not repeat.
Astronomers think that the FRB described in the study of Nature is still in its infancy. It is still surrounded by thick material from the supernova explosion that creates a neutron star. Scientists suspect that recurrent eruptions occur in small FRBs.
Di Li is a senior scientist at Beijing’s FAST telescope and the Chinese Academy of Sciences. He co-authored a study of Nature. He said, “We still call fast radio as a cosmic mystery and it should.”
