While the LMC is often considered an irregular type galaxy ( the NASA Extragalactic Database lists the Hubble sequence type as Irr / SB ( s ) m ), the LMC contains a very prominent bar in its center, suggesting that it may have previously been a barred spiral galaxy.

The Pinwheel Galaxy ( Messier 101 / NGC 5457 ): a spiral galaxy classified as type Scd on the Hubble sequence

On the right of the Hubble sequence diagram are two parallel branches encompassing the spiral galaxies.

In the extended Hubble sequence, the Magellanic irregulars are usually placed at the end of the spiral branch of the Hubble tuning fork.

This, however, can lead to an internalized, self-reinforcing sequence of shame events for which Kaufman coined the term " shame spiral ".

A spiral galaxy is a certain kind of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, forms part of the Hubble sequence.

The shape of an irregular galaxy is uncommon – they do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.

Square removal can be repeated infinitely, in which case corresponding corners of the squares form an infinite sequence of points on the golden spiral, the unique logarithmic spiral with this property.

Both gradient coils can also be turned on in a specific sequence to trace a spiral shape in k-space.

This spiral imaging sequence acquires images faster than gradient-echo sequences, but needs more math transformations ( and consequent assumptions ) since converting back to voxel space requires the data be in grid form ( a set of equally spaced points in both horizontal and vertical directions ).

Lenticular galaxies are often considered to be a poorly understood transition state between spiral and elliptical galaxies, which results in their intermediate placement on the Hubble sequence.

* Spiral: Golden spiral, Golden ratio, Fibonacci sequence

The spiral galaxy, Jupiter, and the four moons ( total of six space objects ) as well as the seven stars of the insignia symbolize the flight's numerical designation in the Space Transportation System's mission sequence.

His observations of phyllotaxis ( numerical relationships between spiral structures in plants ) and the Fibonacci sequence has become a textbook staple.

Edwin Hubble classified these types of spiral galaxies as " SB " ( spiral, barred ) in his Hubble sequence, and arranged them into three sub-categories based on how open the arms of the spiral are.

A " spiral sequence " is a series of spiral moves performed together.

A spiral sequence often includes a change of edge spiral.

Wyatt and Whipple, 1950 ), which is a retardation of the orbital motion of particles by the relativistic aberration of the repulsive force of the impinging solar radiation, causes the dust to spiral into the sun in times much shorter than the age of the Earth.

The first turn of the spiral is the primeval history of humanity in Adam.

The spiral ‐ shaped mouth with horny tooth ridges is reabsorbed together with the spiral gut.

NGC 2997 is a loose face-on spiral galaxy of type Sc.

* IC 4633 is a very faint spiral galaxy.

< font face =" arial " color =" red "> Wire carrying current to be measured .</ font >< font face =" arial " color =" green "> Spring providing restoring force </ font > This illustration is conceptual ; in a practical meter, the iron core is stationary, and front and rear spiral springs carry current to the coil, which is supported on a rectangular bobbin.

In 1912 Vesto Slipher measured the first Doppler shift of a " spiral nebula " ( spiral nebula is the obsolete term for spiral galaxies ), and soon discovered that almost all such nebulae were receding from Earth.

The face-on spiral galaxy is experiencing abnormally high rates of star formation, indicating that it is interacting with one or both members of the group.

Of these, the brightest is Messier 77 ( NGC 1068 ), a 9th magnitude spiral galaxy near Delta Ceti.

It is classified as being between an elliptical and a spiral galaxy because it has faint arms and a large central bulge.

NGC 4622 is a face-on spiral galaxy located 200 million light-years from Earth ( redshift 0. 0146 ).

CD data is stored as a series of tiny indentations known as " pits ", encoded in a spiral track moulded into the top of the polycarbonate layer.

The program area is 86. 05 cm < sup > 2 </ sup > and the length of the recordable spiral is ( 86. 05 cm < sup > 2 </ sup > / 1. 6 µm ) = 5. 38 km.

One of the more significant galaxies in Canes Venatici is the Whirlpool Galaxy ( M51, NGC 5194 ) and NGC 5195, a small barred spiral galaxy that is seen face on.

It is a face-on spiral galaxy 37 million light-years from Earth.

It is a spiral galaxy with an integrated magnitude of 9. 0.

M94 is a small face-on spiral galaxy with an approximate magnitude of 8. 0, about 15 million light-years from Earth.

The amphorae were arranged in a continuous spiral, which required minimal centering and formwork, but was not strong enough for large spans.

The column is composed of 29 blocks of Luna marble, weighting in total more than 1100 t. The spiral stair itself was carved out of 19 blocks, with a full turn every 14 steps ; this arrangement required a more complex geometry than the more usual alternatives of 12 or 16.

A fast spiral drill bit is used in high feed rate applications under low spindle speeds, where removal of a large volume of swarf is required.

The required synchronization of the orbital velocity of a central star with the wave velocity of the spiral arms can occur only within a fairly narrow range of distances from the galactic center.

His autocratic methods prevented the major changes required to halt a downward economic spiral.

Currently, spirals are infrequently performed by men at the Olympic level because it is not a required element nor can men receive points for spiral sequences in the element score of the ISU Judging System.

:; Volute: A handrail end element for the bullnose step that curves inward like a spiral.

After exiting the Perisphere, visitors descended to ground level on the third element of the Theme Center, the Helicline, a spiral ramp that partially encircled the Perisphere.

The first element of the price / wage spiral does not apply if markets are relatively competitive.

This was subsequently developed into a spiral hollow steel tube that had a heating element running through the middle.

A spiral is an element in figure skating where the skater glides on one foot while raising the free leg above hip level.

A seven-story marble spiral staircase is a prominent element of the building's interior.
