Astronomers have detected a strange radio signal coming from another galaxy about 3 billion light years away from Earth. This is the second time scientists have detected such a repeating signal. Astronomers have made an interesting discovery using a giant telescope in China.
Researchers have detected Fast Radio Burst (FRB)
NASA is giving a reward of Rs 54 lakh, how and where to register
The researchers published their findings in a new paper in the scientific journal Nature. Researchers have detected a new fast radio burst (FRB), known as FRB-20190520B. The researchers noted that the signal was “co-located with a compact, persistent radio source and associated with a highly conspicuous-star-formation dwarf host galaxy.

The FRB was detected in May 2019 using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) in Guizhou, China. Additional observations recorded about 75 more FRBs in 2020 over a five-month period. The signal was then localized using .
Radio waves have the longest wavelength in the electromagnetic spectrum. Astronomers suspect that these explosions may have been sparked by some extreme objects. These may include a neutron star.

These extraordinarily fast radio bursts produce the same amount of energy in a thousandth of a second as the sun does in a year. Since these transient radio pulses disappear within a short span of time, they are difficult to track and observe. Since being discovered in 2007, astronomers have struggled to understand what causes the phenomenon.
What is Holoportation? After all, how did NASA send the ‘holoported’ doctor from Earth to the International Space Station?
In a study published in the journal Nature, researchers from the National Astronomical Observatories, Chinese Academy of Sciences, have detailed the FRBs detected by the five-hundred-meter Aperture Spherical Radio Telescope (FAST).
