new (in Latin,nova) star that faded as quickly as it appeared. Until Brahe discovered the disappearing star (which we know today was a supernova, and not a new star but rather a dying star), it was widely believed in the West that the stars never changed [source:Tycho Brahe ...
motion or spinning and there is not a visible reason for this motion and the invisible reason has an effect that appears to be caused by an object with a mass greater than three solar masses (too big to be a neutron star), then it is possible that a black hole is causing the motion...
This kind of star fuses heavier and heavier elements in its core, eventually becoming so massive that it cannot hold itself up against gravity, Borowski said. The result is a huge explosion called a supernova. The star's core lives on as either a neutron star or a black hole, according ...
The great Hubble is also the world'smain observer of ultraviolet lightthat emanates from sources in the universe. Ultraviolet light has shorter wavelengths and carries higher energies than visible light and points astronomers to hot, energetic processes, such as those taking place inyoung stars and...
How Earth could die: Artist’s conception of Scholz’s star and its brown dwarf companion during its flyby of the solar system 70,000 years ago. The Sun (left, background) would have appeared as abright star. The pair is now about 20 light-years away from the Sun. Image Credit: Mic...

The solar system comprises 8 known planets (with Pluto no longer considered a planet) orbiting the sun. The solar system is so-called because the sun is at the center, having the greatest gravitational pull that sustains the rotation of the planets around it....
Today, competition among scientists is common, especially in “hot” topics, but this was not always the case. A good example of this is Linus Pauling’s (1901 − 1994, see, eg, [19]) work on trying to solve some protein structures in the late 1930s. This proved to be a for...
appears in the sky for several days, or weeks. The outer layers of the star, containing traces of the heavier elements, are blown away into space, and the core collapses further into either a neutron star or a black hole. (Neutron stars and black holes have been discussed in Chap.7.)...
(Winter-star, I think, that is) A song of happiness, Ernest Rhys Earendel (NASA, ESA, CSA) Somehow the cosmic horizon is sprinkled with seeds of black holes. Primordial massive black holes could beremnantsof the very first and exceptionally massive and metal-free stars. So inflated from ...
