* ''ComicBook/InfiniteCrisis'': Planets are created and destroyed, not that far from the Earth's orbit, without disrupting the orbit of the Earth, and the orbit of other bodies in the solar system, and without causing global flooding on the Earth or causing any debris to hit the Earth.

to:
* ''Film/IndependenceDay'': A ship, said to be a quarter of the size of the Earth's moon, is destroyed not too far from the Earth's atmosphere, without sending debris crashing into the planet or disrupting the tides.

* Subverted in Webcomic/OnePunchMan, as Saitama manages to destroy the meteor threatening to destroy the city... but doesn't destroy any of the meteorites coming from the broken pieces, completely decimating several cities.

* In the episode ''A Planet Blown To Pieces'' of ''WesternAnimation/IlEtaitUneFois''... Space, the leaders of the [[TheFederation Omega Confederation]] discuss about the primary star of a multiple star system where the antagonists (Cassiopeia) are building a military base going supernova (it fall into the next category too, since they often refer to it as a ''nova'') soon. Not only supernovae do not work the way it's explained there but also in the show people are far more concerned about the debris of the explosion -that moves far slower than the light, thus not reaching the planet where's the base is located until days later- than the energy emitted by it. In RealLife, the energy emitted by the supernova is '''''far''''' more dangerous than its debris, and it moves at the speed of light -so no days to rescue the prisoners used by Cassiopeia as construction workers, as happens there (at best hours)-[[note]]The sheer dumbness of a general who decides to build a base in a place so dangerous ''and even with the supernova having destroyed the planet'' sends ships to savage base's equipment is not discussed here.[[/note]]

In reality, a nova is an outburst caused by a white dwarf sucking material off of a companion star; when enough material is accreted on the white dwarf's surface, it gets hot enough and dense enough to undergo nuclear fusion. This produces an outburst that reaches peak brightness in a few hours, then cools back down again over a few days or weeks. Some white dwarfs are known to be "recurrent novae", undergoing a nova outburst at more-or-less regular intervals of a few years or decades. (If the white dwarf accretes ''so'' much material that its mass exceeds 1.44 solar masses, it will explode spectacularly in an event called a Type Ia Supernova; this event turns it into a neutron star.) When a sunlike star ends its main sequence lifetime, it doesn't "go nova", it swells into a ''red giant'' over the course of a few million years.

In the process, the center is expected to undergo a "helium flash", similar to a type Ia supernova. The core stays together and the effects don't reach the outside of the star because of the rest of the star sitting on top.

** Same for the haloes visible around them, that are optical effects, except in some cases where those haloes are actual nebulosities surrounding the photographed star(s). ** A related effect are vertical images that often appear images of bright stars taken with telescopes that mount CCDs -the electronic devices found at the heart of digital cameras- instead of traditional photographic plates, that are produced when the individual bins of a CCD overflown and spill in vertical as is easier to happen due to the CCD's structure, an effect known as [[http://en.wikipedia.org/wiki/Charge-coupled_device#Blooming Blooming]]
