Functionalist Perspective on Health,y thin layer called the chromosphere. The chromosphere is the lower atmosphere of the Sun. The upper atmosphere of the Sun is called the corona. The solar wind consists of highly energetic ions escaping the Sun’s gravity from the corona.

Acta Neurochirurgica Supplementen Sawyer developed a classification scheme for globular clusters. The Shapley-Sawyer classifications are numbered with Roman numerals I to XII based on the concentration of stars in the cores of the clusters. Level I clusters have the highest concentration of stars in their cores. Level XII clusters have virtually no concentrated cores.

Devising Healthcare and Society,e from Earth. The orbits of comets do not necessarily lie in or near the ecliptic. When their distant orbits are perturbed, comets can enter the inner solar system.

Astrophotography,ra without a lens is attached to a telescope in place of the eyepiece. Thus, the telescope becomes the lens for the camera, producing high-magnification images. Digital images must be calibrated using dark frames, flat-field frames, and bias frames.

The Moon,arly sized moons around Jupiter, Saturn, and Neptune, the Moon does not orbit in Earth’s equatorial plane. It orbits in a plane tilted five degrees to the ecliptic plane (the plane of the Earth’s orbit around the Sun). The Moon is composed of silicate rocks and does not have an iron core or magnetic field like the Earth.

Planetary Nebulae and Supernovae Remnants,The supernova creates a shell of expanding gases that appears as a nebula. These nebulae are called supernovae remnants. Planetary nebulae and supernovae remnants are transient phenomena. Eventually, the gases spread out to the point where they are no longer visible.
