SN 2015cp, a supernova at a distance of 545 million light-years, was triggered by a companion star which marked the death of its partner in the binary system. Supernovae are quite common because all the stars of the universe eventually run out of fuel and die with a massive explosion. Having said that, there…
Astronomers from the University of Warwick have found direct evidence suggesting that the white dwarf stars are solidifying into crystals. A white dwarf star in a dense stellar core remnant, which is mostly made up of electron-degenerate matter. All the luminosity of these stars come from the stored thermal energy as there is absolutely no…
Nova Vulpeculae 1670 is merely a collision between two dwarf stars. The term ‘Nova (Novae)’ refers to a transient astronomical event that causes sudden appearance of a bright, apparently new star which gradually fades away over several weeks. In some cases, the fading process may take many months. All the novae, which have been observed…
Scientists may have to reconsider the mass that a celestial object needs to have to initiate nuclear fusion. The term ‘Stellar Evolution’ refers to the process by which a star changes over the course of time. The lifetime of a star is inversely proportional to its mass. Consequently, massive stars live for a few million…
We might get electricity from Nuclear Fusion much earlier than we anticipated. Nuclear Fusion refers to a reaction where two or more nuclei fuse into each other to produce one or more atomic nuclei and subatomic particles like protons. Massive amounts of energy are released during this process and this accounts for the difference in…
Mankind is one step ahead in achieving the nuclear fusion. Considering this a source of the future, nuclear fusion can provide an unlimited amount of energy without pollution, through a process similar to that taking place inside the Sun. Magnetic field, intense pressure and heat is needed for the cores of the lighter chemical elements…
