NGC 4567 and NGC 4568 (nicknamed the Butterfly Galaxies[ 4] or Siamese Twins[ NB 1][ 5]) are a set of unbarred spiral galaxies about 60 million light-years away [ 1] in the constellation Virgo. They were both discovered by William Herschel in 1784. They are part of the Virgo Cluster of galaxies. These galaxies are in the process of colliding ...
NGC 6302 (also known as the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar planetary nebula in the constellation Scorpius. The structure in the nebula is among the most complex ever seen in planetary nebulae. The spectrum of Butterfly Nebula shows that its central star is one of the hottest stars known, with a surface temperature in ...
Orrery. A small orrery showing Earth and the inner planets. An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often ...
The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...
Size (left) and distance (right) of a few well-known galaxies put to scale The following is a list of notable galaxies . There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster , and an estimated 100 billion in all of the observable universe .
Coordinates. 14°41′51″S75°8′6″W / 14.69750°S 75.13500°W. Location of Nazca lines in Peru. The Nazca lines ( / ˈnɑːzkə /, /- kɑː / [ 1 ]) are a group of geoglyphs made in the soil of the Nazca Desert in southern Peru. [ 2 ] They were created between 500 BC and 500 AD by people making depressions or shallow incisions in ...
In the context of fast Fourier transform algorithms, a butterfly is a portion of the computation that combines the results of smaller discrete Fourier transforms (DFTs) into a larger DFT, or vice versa (breaking a larger DFT up into subtransforms). The name "butterfly" comes from the shape of the data-flow diagram in the radix-2 case, as ...
