Astronomers at Max Planck Institute of Germany discover a new black hole named Holmberg 15A
Astronomers at the Max Planck Institute of Germany have recently discovered a new black hole named Holmberg 15A that is clocking in at 40 billion times the mass of the Sun. The black hole is supergiant elliptical galaxy i.e. around 700 million light-years away from Earth and resides right at the centre of the Abell ..

Helium hydride ion to be the first molecule detected in space
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 ..

NASA decides to launch SPHEREx Mission to investigate origins of our Universe
US space agency NASA has recently unveiled a new space telescope ‘SPHEREx’ that would begin a two-year mission in 2023 to map the entire sky in order to understand the origins of the universe. The acronym SPHEREx stands for ‘Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer’. The spacecraft’s objective ..

Hubble discoveres a new dwarf galaxy ‘Bedin 1’ in cosmic neighbourhood
The Hubble Space Telescope (HST) has made an unexpected discovery of a new dwarf galaxy in our cosmic neighborhood. Named Bedin 1, the galaxy is approximately 30 million light-years away and 2 million light-years from the nearest plausible large galaxy host ‘NGC 6744’. The object is classified as a dwarf spheroidal galaxy because it measures ..
