Researchers from the Goddard Space Flight Center of the National Aeronautics and Space Administration (NASA) have announced that they have detected radiation that could be a sign of the existence of the first stars formed during the dawn of the universe. These stars are the building blocks of the current system of stars, including our own Sun.
Astronomers believe that the universe was formed after a big bang approximately 13.7 billion years ago and remained in darkness for about 100-200 million years. Later, when hydrogen atoms began to combine and release energy, they formed extremely hot and bright stars, with masses ranging from several hundred to a million times that of the Sun. These stars existed for a brief period of just a few million years. The remnants of these stars may be the radiation that the NASA researchers have detected.
Nasa astronomer Alexander Kashlinsky stated that the detected radiation is the first tangible and reliable information regarding these stars. If this discovery is confirmed to be accurate, it will help scientists determine how later stars were formed.
