Plane, planing planets

The Earth and other planets form a plane around the Sun called the ecliptic and the motion of all of the planets, including the Sun and the Moon, appears on this... [Pg.26]

Now for the photon flux. As the altitude increases, the atmosphere looks thinner so the light has to pass through a smaller amount of atmosphere dependent on the zenith angle, which is related to the latitude on the planet and the angle that its axis of rotation makes with the plane of the solar system, the season of the year and hence the position of the planet in its orbit. The depth of atmosphere through which the Sun s rays pass is given by dz sec0. Hence the optical absorption is ... [Pg.218]

After having made this distinction, the tower can be used paradoxically, to transport consciousness for a very specific purpose. First, let s be quite clear that consciousness itself doesn t actually require any vehicle to be anywhere. Consciousness is omnipresent. But consciousness does require a vehicle to function, to be effective, upon any given plane. In very advanced practice, the tower is moved within the etheric counterpart of the Earth, first to the North Pole, where our planet receives most of the incoming cosmic radiations from the stars, and from there to other locations, even to the great diamond-crowned Tower at the principal abode of the immortal Sages, that august sanctuary which is, as its name states, the place where the will of God is known. This is a high level of practice that is only undertaken with direct tuition. [Pg.128]

The orbits of asteroids in the main belt between Mars and Jupiter show gaps in both heliocentric distance and inclination (degrees from the ecliptic, the plane in which the planets... [Pg.389]

The same materials developed for aerospace planes may one day be applied to commercial travel. Hypersonic aircraft traveling at many times the speed of sound would reduce the time of a transpacific flight from America to Australia from 16 hours to a mere 3 hours. Whats more, the altitude of the aircraft would necessarily be so high that travelers would get a clear view of the curvature of Planet Earth. [Pg.632]

In Revelation we read "He that overcometh will I give the morning star." This "star" is SOL, perfected by LUNA, -Solomon by the Queen of Sheba. This bright morning star is the same as that which announced the birth of Christ to the shepherds. It is Venus, or Love, the "fulfillment of all," as Christ himself declared. This star is fundamentally the Sulphur (Sol) of the Sages, and it reaches the state (plane, or planet) of Venus (Copper) just AFTER the White Work, and from this one goes on to Gold. [Pg.50]

Bob pushes the thoughts out of his mind and enjoys the grass. For centuries, scientists hypothesized that the Sun and planets were born from a rotating disk of cosmic gas and dust. The flat disk constrained the nascent planets to have orbits lying roughly in the same plane. This nebular theory was proposed as far back as 1755 by the philosopher Immanuel Kant. [Pg.92]

Models of irradiated disks predict four chemically distinct zones (see Fig. 4.1). (I) Zone of ices in the cold mid-plane opaque to incoming radiation. Chemistry in this region is dominated by cold gas-phase and grain-surface reactions. Here Infrared Space Observatory (ISO) and Spitzer observations confirmed the existence of ices, various silicates and PAHs (polycyclic aromatic hydrocarbons e.g. van den Ancker et al. 2000 van Dishoeck 2004 Bouwman et al. 2008). (II) Zone of molecules, a warm molecular layer adjacent to the mid-plane, dominated by ultraviolet/X-ray-driven photochemistry (III) the heavily irradiated zone of radicals, a hot dilute disk atmosphere deficient in molecules and (IV) the inner zone, inside of the ice line where terrestrial planets form. [Pg.11]

For theories of planet formation and disk chemistry, the mid-plane temperature, Tm, is more important than the surface temperature. Also, to solve Eq. (3.4) or Eq. (3.6) we need to know v, which depends on Tm, not on Te. For irradiation-dominated disks Tm is roughly equal to the surface effective temperature Te. For disks in which accretional heating is important this is not the case. A rough estimate for the mid-plane temperature valid for any case is T4 = (3/8)T4viscrR + r4irr, where T,visc and 7). T are given above and tr = E/cr with /cr the Rosseland mean opacity of the gas-dust mixture at the temperature Tm. The expression for Tm is therefore not explicit, as it is also used for kr. For realistic dust opacities it requires a numerical iterative solution procedure. For a gray opacity, or for piecewise power-law opacities, such as those in Bell et al. (1997), it can be solved analytically. [Pg.75]

The recent detection of the [Nell] line emission at 12.81 pm from several disks by the Spitzer Space Telescope (e.g. Pascucci et al. 2007) has confirmed theoretical predictions that the disk atmosphere is heavily ionized and superheated, either by X-rays (Glassgold et al. 2007) or by extreme UV irradiation (Pascucci et al. 2007). However, X-rays and cosmic-ray particles (CRPs) may not be able to penetrate further toward the mid-plane of the planet-forming disk zone (r 3-20 AU), which makes the mid-plane essentially neutral and thus stable against accretion ( Dead Zone Gammie 1996 Dolginov Stepinski 1994). [Pg.104]

This is a perverse evolutionism, with a vertical axis. We emerge of lower forms. It also has a horizontal plane. We are all made of the same stuff, the same elements. From planet to self, all is made of the same materials interacting. History is in nature, and nature is an animated unity. [Pg.42]

Mars is smaller than Earth. Its diameter of about 2,111 mi (3,397 km) is a little over half that of Earth, and it is only 10% as massive as our planet. Mars has seasoirs because the tilt of its axis relative to the plane of its orbit is nearly the same as Earth s. It rotates on its axis once every 24 hours and 40 minutes, so a Martian day is just a little longer than one of ours. The Sun would appear larger in the Martian sky because Mars is half as far from the Sun as the Earth, and its year is 687 (Earth) days long. [Pg.233]

The inclination of Mercury s orbit to that of the ecliptic plane (the plane of Earth s orbit about the Sun) is 7.0°. This slight orbital tut dictates that when Mercury is at inferior conjunction it is only rarely silhouetted against the Sun s disk as seen from Earth. On those rare occasions when Earth, Mercury, and the Sun are in perfect alignment, however, a solar transit of Mercury can take place, and a terrestrial observer will see Mercury move in front of, and across the Sun s disk. A transit of Mercury can only occur when the planet is at inferior conjunction during the months of May and November. During these months Earth is near the line along which the orbit of Mercury intersects the ecliptic plane— this is the line of nodes for Mercury s orbit. Approximately a dozen solar transits of Mercury occur each century, and the final transit of the twentieth century occurred on 15 November 1999. [Pg.287]

For Galileo studies of the moon or the phases of Venus were not qualitatively different from studies of the pendulum and of inclined planes. The approach was the same, the kind of results expected were governed by the same outlook. Tycho Brahe and Kepler brought the observation of planetary motion and planetary theory closer to perfection, and, finally, Newton combined the motions of the planets and the laws of falling bodies into one universal law of gravitation. The universe held together. [Pg.20]

Nagaoka s model resembled a planet with moons orbiting in a flat plane. He believed the core had a positive charge, and the negative electrons were In orbit around it. ... [Pg.63]
