The FRB was part of one of the magnetar’s most prolific flare-ups, with the X-ray bursts lasting less than a second. At the end of their lives, stars that are between four and eight times the sun's massburn through their available fuel and their internal fusion reactions cease. Introduction: The LIGO-VIRGO collaboration, three members of which won this year’s physics Nobel Prize, detected the merger of two neutron stars –extremely dense, massive but tiny, objects. Ordinary stars maintain their spherical shape because the heaving gravity of their gigantic mass tries to pull their gas toward a central point, but is balanced by the energy from nuclear fusion in their cores, which exerts an outward pressure, according to NASA. Brown dwarfs are thought to form in the same way that stars do – from a collapsing cloud of gas and dust. A very young, lightweight star, less than 10 million years old, that it still undergoing gravitational contraction; it represents an intermediate stage between a Protostar and a low-mass main sequence star like the Sun. In a nova, the system can shine up to a million times brighter than normal.
