NASA’s flying observatory SOFIA has detected Helium hydride ion (HeH+), the first molecule that formed almost 14 billion years ago towards a planetary nebulae. It is the first type of molecule that formed in the universe after the Big Bang. At that time, ionised hydrogen and neutral helium atoms reacted to form Helium hydride ion. ..
Astronomers from Japan, Taiwan, and Princeton University discover 83 quasars powered by supermassive black holes in distant universe
Astronomers from Japan, Taiwan, and Princeton University have discovered 83 quasars powered by supermassive black holes in the distant universe, which were formed when the universe was only 5% of its current age. These quasars are lying 13 billion light-years away from the Earth. The team used data taken with ‘Hyper Suprime-Cam’ (HSC) instrument, mounted ..
