(Physical Geography) (intr) (of the wind) to change direction in an anticlockwise direction in the northern hemisphere and a clockwise direction in the southern
Likewise, the earth's elliptical orbit also causes variations in the sun's pull on the tides as we move from the closest point to the farthest point (called apogee) over the course of a year. The Earth and Moon orbit about their common center of mass, which lies about 4,700 kilometres from Earth's center (about three quarters of the Earth's radius)
Is A Moon Necessary For A Planet To Support Life? : NPR
So there's a hypothesis called the Rare Earth Hypothesis by Peter Ward and Donald Brownlee at the University of Washington and, you know, people have been trying to solve Fermi's questions for a long time. And suddenly, Enrico Fermi sits down and thinks about it for a while and he says, where is everybody? As if - if you calculate how many alien civilizations there should be out there, then you'd come up - usually, if you kind of plug in the typical numbers, you come up with huge numbers of civilizations in the galaxy, but we haven't found any
a collection of numbers, objects, etc, that is treated as an entity: 3, the moon is the set the two members of which are the number 3 and the moon (in some formulations) a class that can itself be a member of other classes 4. Many disparate senses collect under this word because of the far-flung meanings assigned to the verb: "Action of hardening," 1837; also "manner or position in which something is set" (1530s), hence "general movement, direction, tendency" (1560s); "build, form" (1610s), hence "bearing, carriage" (1855); "action of fixing the hair in a particular style" (1933)
Do Stars Move?
Consider the famous Mars mystery; astronomers used to be puzzled as to why the planet appeared to stop its movement against the background stars, go backwards and then go forwards again. And if you watch the sky over a few hours in most locations on Earth, you can see the same thing happening: stars rising in the east, and setting in the west
Other arguments adjust the sidereal signs such that Aldebaran's ecliptical longitude is exactly in the center of sidereal Taurus; or that of Antares in the center of sidereal Scorpio (those being two of the four royal architects (meaning: revealing structure in the heavens). It is also interesting to consider that the perpetual use of tropical astrology today is an energetic that perpetuates a chasm in time that continues to widen at the rate of Earth's precession, one keeping the masses drifting in time-confusion rather than living in the present and truth that the true sidereal zodiak reveals
Since the folks in other parts of the planet came from Africa, it would seem to me that the African Nations are the root cause of gumball warming and therefore should pay the folks who were smart enough to get the hell out that armpit. Kum Dollison says: August 24, 2009 at 5:20 pm Now, do you suppose 15, or 20 of those storms, worldwide, any given year would make a difference? Curiousgeorge says: August 24, 2009 at 5:22 pm jeremiel (16:20:29) : So I suppose the Earth must have tilted big time when the asteroid hit which wiped the dinosaurs out and superheated the oceans and sky for that matter? Nope
How does the light hit the world? Use the example from above and consider: Is there much difference between how it hits us and how it hits Australia? Is it possible for these people to have a different season than we are having with the world like that? Could we move the globe around to try it out? Is it possible to make only one half of the world get warmer than the other? They may see where this is going, and say tilt the one half away or towards the light to make it warmer. We should be careful to make sure we are certain which hemisphere we mean when we talk about Summer! So, when it is Summer for the U.S., for example, our part of the Earth is tilted towards the Sun
The mechanism by which the Earth's orbital eccentricity could affect the climate in such a direct and important way is not known, and some researchers believe that the 100,000-year climate cycle is not due to orbital variations at all. Milankovitch's work was an attempt at explaining the ice ages, and it built upon previous astronomical theories of climate variation postulated by Joseph Adhemar and James Croll in the 19th century
Instead, the areas around the equator would receive the most sun and the northern and southern hemispheres would be stuck in a gradual gradient of hot to cold. Is it true that the earth is closer to the sun in winter? Because of its elliptical orbit, the earth is closer to the sun during the northern hemisphere's winter
By the way, taking about heavenly bodies, is it possible that you could see (through a binocular, that is) a red light blinking from a far away object in the sky that remains fixed in its position over time? could it be a satellite? Do satellites have red bulbs attached to them, sort of beacons? Silverhill Posted 23 February 2008 at 07:13 pm No, there are no beacon lights on satellites. In a chance encounter with Engineer George Silver, who usually sent all his time at the MIT satellite office at Cape Kennedy, a tech asked him in frustration if George had ever seen the computer run slowly or at reduce capacity
But apparently it would not be so radically different that its absence would necessarily prevent humans from ever seeing the light of day.Another question is what would happen if the Moon were to suddenly decide to say goodbye
The distance of the Earth from the sun is just the opposite of what someone would expect to find with respect to the seasons in the Northern Hemisphere. In this case it would be winter--yuck! Many people know that the axis of the Earth points to a very famous star in the nighttime sky called the North Star or Polaris
They Erupted into Northern Europe in the 3rd Century BCE as the Royal Scythians, Celts, Cymrics, Cimmerians, Goths, Angles, Saxons, Ostrogoths, Visigoths and Frisians. They Disappeared into the Mists of History as they Migrated in Waves up through Georgia through the Caucasus and Followed the Tracks of their Cousin Dan who left his Name on the Rivers of his Passage (Don, Dniester, Dnieper, and the Danube) as they Migrated Northwestward towards Denmark
