# Terminoiogy of spiral classifier

Galaxies range from 1,000 to 100,000 parsecs in diameter and are usually separated by millions of parsecs. Edwin Hubble invented a classification of galaxies and grouped them into four classes: spirals, barred spirals, ellipticals and irregulars. He classified spiral and barred spiral galaxies further according to the size of their central

• Hubble Classification | COSMOS

The Hubble Classification scheme for galaxies, often referred to as the “tuning fork” diagram. Edwin Hubble originally identified an evolutionary sequence for the galaxies (from early-type to late-type) as one moved from left to right across the diagram. Although this is now known to be a false interpretation, the terms ‘early-type’ and

• The Spiral: Why Everyday Mathematics Distributes Learning

Different terms are used to describe such an approach, including “distributed” and “spaced.” A spiral approach is often contrasted with “blocked” or “massed” approaches. In a massed approach, learning is concentrated in continuous blocks. In the design of instructional materials, massing is

A spiral staircase is an attractive, durable, and space-saving choice for a home or office building. Space saving is, of course, one of the greatest benefits of any spiral staircase. Unlike traditional staircases, a spiral staircase does not have a large footprint and can be installed in small spaces, making it an exceptionally good choice for

SPIRAL. Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, form part of the Hubble sequence. Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. IRREGULAR

Spiral galaxies are classified in terms of increasing tightness of their spiral arms as types Sa, Sb, and Sc. However, many spiral galaxies are aligned edge-on to Earth and their spiral arms cannot be seen. ...
