Webb Space Telescope May Discover First Stars Formed Around Primal Black Holes
Black holes of various masses may have formed during the first second of the Big Bang and ultimately ended up being the source of dark matter. In a new scenario,…

This artist’s impression shows how the material ejected by the SN 1987a supernova is distributed, based on information provided by the Sinfoni spectrograph. © L. Calçada, ESO A supernova is…
Supermassive black hole is believed to be hiding in dwarf galaxy near Milky Way
This is unheard of and questions the growth models of galaxies and supermassive black holes. The dwarf galaxy Leo I orbiting the Milky Way would contain at its center a…
There would be a supermassive black hole in a dwarf satellite galaxy of the Milky Way
This is unheard of and questions the growth models of galaxies and supermassive black holes. The dwarf galaxy Leo I orbiting the Milky Way would contain at its center a…
Closest pair of supermassive black holes known to date
Supermassive black holes are everywhere in the observable cosmos. They are sometimes found in pairs in a galaxy, to the point of forming a binary supermassive black hole. The closest…
Astronomers have tracked down closest pair of supermassive black holes known to us
Supermassive black holes are everywhere in the observable cosmos. They are sometimes found in pairs in a galaxy, to the point of forming a binary supermassive black hole. The closest…
Gravitational waves would have made the Big Bang space-time turbulent
Space-time is not a material medium, yet its dynamics resemble that of fluids. Like them, it could have become turbulent, especially at the time of the Big Bang, when it…
