In what is considered a strange discovery, astronomers have detected a radio signal coming from another galaxy, which happens to be about 3 billion light-years away from Earth. However, this is not the first time such a thing has happened. Once earlier, scientists discovered such a frequent signal. The results were published in the scientific journal Nature. Researchers have discovered a new fast radio burst (FRB), dubbed FRB 20190520B. According to the researchers, the signal was “co-location with a compressed, continuous radio source and associated with a dwarf host galaxy of highly specific star formation.” Discovered using the Five Hundred Meter Aperture Spherical Radio Telescope (FAST) in Guizhou, China, in May 2019.
According to several observations, the emitted object was responsible for sending smaller radio bursts between the FRBs.
“The FRB field is moving very rapidly at the moment and new discoveries are being made monthly. However, big questions remain, and this organism is giving us difficult clues about those questions,” study co-author Sarah Burke Spullor said in an official statement. “These properties make this property very similar to the first FRB that was located — also by the VLA — back in 2016.” Casey Law, of the California Institute of Technology and one of the study’s co-authors said in a statement to the National Science Foundation. It is called FRB 121102 and the characteristics are similar to FRB20190520B. “Now we actually need to explain this double puzzle and why FRBs and persistent radio sources are sometimes found together,” she told CNN.
The researchers theorized that FRB 190520 may be “newborn,” meaning that it is “still surrounded by dense material from the supernova explosion that left the neutron star.” The theory states that once the matter dissipates, the impulse signals will also decrease. However, the researchers cautioned that some questions remain unanswered.
Meanwhile, in another space-based discovery, NASA’s Hubble Telescope has captured the largest near-infrared image ever. The image covers a large area. According to the researchers, it can help to understand the star-forming regions of the universe and very distant galaxies. The image is named 3D-DASH, and it contains many stars and many other celestial bodies. In a statement from the University of Toronto, Lamia Mulla, lead author on the paper, said that since the Hubble Space Telescope was launched more than 30 years ago, it has led to a “renaissance in the study” of how galaxies have changed in the last 10 billion years of the universe’s life.
