Planets Around Other Stars Planets Around Other Stars What are exoplanets? Throughout recorded history and perhaps before, we have wondered about the possible existence of other worlds, like or unlike our own. The earliest understanding of the solar system showed us that there were indeed other worlds in orbit about our Sun, and steadily growing understanding of their natures shows that all are dramatically different from Earth, and mostly very different from one another. As we came to understand that the stars in the sky are other suns, and that the galaxies consist of billions of stars, it appeared a near certainty that other planets must orbit other stars. And yet, it could not be proven, until the early 1990’s. How we know that there are planets around other stars? Most of the detected exoplanets have revealed their presence by small effects that they have on their star. What do we know about our exoplanet neighbors? In other reports, a number of planets with masses near that of Earth have been detected.

Solar System, Solar System Information Our Cosmic Neighborhood From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. Since the invention of the telescope, three more planets have been discovered in our solar system: Uranus (1781), Neptune (1846), and, now downgraded to a dwarf planet, Pluto (1930). The four planets closest to the sun—Mercury, Venus, Earth, and Mars—are called the terrestrial planets because they have solid rocky surfaces. Nearly every planet—and some of the moons—has an atmosphere. Moons, Rings, and Magnetospheres There are 140 known natural satellites, also called moons, in orbit around the various planets in our solar system, ranging from bodies larger than our own moon to small pieces of debris. From 1610 to 1977, Saturn was thought to be the only planet with rings. Most of the planets also have magnetic fields, which extend into space and form a magnetosphere around each planet.

Brain Quest ® || It's O.K. to Be Smart! Ordering the Planets Remembering which order the planets come in can be difficult, so why not teach your class the following tricks? You could also ask the children to try to make up their own! (all lists should be read downwards) The International Astronomical Union have voted to change the status of Pluto. Denise Dickens also gave the following useful advice: If you get confused as to which M comes first remember, never put a Mars bar near the sun.

World Sunlight Map Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and darkness. The clouds are updated daily with current weather satellite imagery. The Mercator projection used here is one way of looking at the spherical earth as a flat map. Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted. Compare this with Peters, Mollweide or equirectangular projection maps. Also available is a semi-realistic view of dawn and dusk from far above the Earth, a look at the moon, and information about how this works.

Freely Educate BBC Solar System – Discover the beauty and strangeness of space Recapitulation The embryonic development of all vertebrates shows remarkable similarities as you can see from these drawings (supplied by Open Court Publishing Company). The drawings in the top row are of the embryonic stage called the pharyngula. At this stage ("I") they all contain a: notochorddorsal hollow nerve cord a tail extending behind the anus a series of paired branchial grooves. The branchial grooves are matched on the inside by a series of paired gill pouches. In the other vertebrates shown here, the grooves and pouches disappear. Anatomical Recapitulation The idea that embryonic development repeats that of one's ancestors is called recapitulation. This is a distortion of the truth. We should also keep in mind that embryonic development prior to the pharyngula (stage I) may also be very different in the different groups. Another Example Fossil evidence suggests that the ancestors of the insects had a pair of legs on each of their body segments. Biochemical Recapitulation

Welcome - Beautiful Feet Books, Inc. Fun Solar System Facts for Kids - Interesting Facts about the Solar System *Note that in the image above the sizes are to scale, but the relative distances are not. The solar system includes the Sun and all the objects that orbit around it due to its gravity. This includes things such as planets, comets, asteroids, meteoroids and moons. The Solar System formed around 4.6 billion years ago. There are eight planets in the Solar System.

10 Incredible Photos of Animals In The Womb Animals The chance to see things from a different perspective ranks among humanity’s great needs. The following images of animals in the womb offer a totally new way of seeing other species on this planet; they cause us to pause, and—at least for a short time—to reflect on everything that is incredible about existence. This photo shows a bottlenose dolphin about six months through its gestation period. Halfway through its twenty-two month gestation period, this Asian elephant is a perfect miniature of its already-born brethren. Sharks are extremely rare among fish, since they bear their young in the fashion of a mammal. Thanks to ultrasound, we can see through the eggshell of this emperor penguin chick. Looking rather like a small bear, a half-developed chihuahua puppy is already developing its distinctive canine features. Cats may hate water, but this two-month-old cheetah—as yet unborn—has no choice but to swim in amniotic fluid. Here’s an exception to the title of this list.
