How Are Constellations Useful To Astronomers

3. Based on your answers, why is it warmer in summer than in winter? It is warmer in the summer then in the winter because the Earth’s tilt is

Currently, the concept of a year is based on the earth's motion around the sun. The time from one fixed point, such as a solstice or equinox, to the next is called a tropical year; its length is currently 365.242. Our concept of a month is based on the moon's motion around the earth, although this connection has been broken in the calendar commonly used now, the Gregorian calendar. The time for the moon to complete a full cycle of phases is called a synodic month, and its length is currently 29.53 days. Note that these numbers are averages. The actual length of a

c) Mark the region that is both visible from earth and illuminated by the sun. That region will be the phase of the moon we on earth see.

5. A) What would you expect to happen to the temperature on Earth if the amount of energy radiated by Earth increased but the amount coming from the Sun stayed the same?

The autumn constellations Andromeda and Perseus, along with Cetus, Pegasus, Cassiopeia and Cepheus, are richly intertwined in mythology, but are vastly diverse in the objects they present to astronomers. While Perseus lies along the Milky Way, and offers many dazzling open star clusters and diffuse nebulae, Andromeda lies away from our galaxy's plane, and introduces us to the inhabitants of intergalactic space. Some of the finest celestial objects reside in these constellations, and it is well worth braving cool autumn nights to observe them.

Every clear, cloudless night, away from the bright town lights, the night sky treats us to a dazzling spectacle. Countless twinkling stars shine down from the heavens, sprinkled all around like fairy dust. It’s illustrated right above us much like Michelangelo’s Sistine Chapel. But just like the painting, the display is complex and difficult to understand. There are many different parts of the sky with many different topics to go over. One of those topics is the intricacy of constellations. In order to understand what exactly they are, one must start from the beginning, so the most appropriate place to start off is the birth of a star.

A Sidereal and a Synodic month refer to the periods of bodies in orbit. The difference is that a Sidereal month refers to the required time for the stars to complete a period while a Synodic month is the required time for the solar body to complete a period. A Sidereal month lasts 27 days and

For this evaluation essay, I chose four sources for it. The first two material are a journal and one news about the definition of the Pluto. For the third one is a book of introduction of Astronomy, while the last one is a professional source for solar system. All of these resource are written by experts, but not all of them can be cited as an academic source in a research paper.

If you look outside your window and stare up at the night sky, you will see multiple little, tiny, bright dots. At first, the bright dots will look like nothing. The stars will just be random little dots, but if you look a little more you will start to see that these stars connect in different ways. If you look a little closer you can start to see figures and patterns. These pictures in the night sky are called constellations. For many years in history, people, scientists, and astronomers have observed and studied the constellations. They would see a figure among the stars and come up with a name and story as to why they are up in the sky. They would name the constellations according to what was important to them. For example, the Chinese would

Ascertaining the defining characteristics associated with the celestial bodies of astrology will establish the novice in the fundamentals of astrology, and enhance the comprehension of adept astrologers. After all, as planets orbit established positions, the axis of astrology encompasses the idiosyncrasies of the planets. Additionally, a familiarization of Greek and Roman deities benefits the comprehension of the various planetary personalities.

when the group of priests did not meet regularly, the calendar fell out of line (Aldrete). Roman

The Jewish calendar is actually both lunar and a solar calendar. The Jewish calendar uses each new moon for one new month. And each complete

On this day, the northern hemisphere is tilted the farthest towards the sun, making the day the longest and the hottest. For the southern hemisphere, this is the shortest day of the year because they are tilted away from the sun. On September 21st, or the Autumn equinox, the day’s length is the same as the night’s length. On December 21st, it was the northern hemisphere’s Winter solstice, which is also the southern hemisphere’s summer

Every individual day has a 1-13 numerical correspondence. Then, it was given its own glyph or image. There are 20 different glyphs utilized and they become the names of the days they are associated with. After each cycle, this calendar repeats itself. The Haab’ lasts 365 days and corresponds to the length of one complete solar year. Haab’ allows for 18 periods, or months with 20 days. So on this calendar, the numbers ranging from 1 to 20 represent each day of the month. Because a true solar calendar lasts 365.2422 days, the Mayas “added five days to the end of the year. This short five day time period at the end of the cycle is known as Wayeb” (Foster, 2002, p.252). Our calendar today make up for that problem with the addition of Leap Year every four years. We add that extra day to compensate for the true length of a solar year. The two previous calendars were a solar and religious calendar. Now, the Long Count provides an astronomy-based version. The Long Count “recorded a continuous and chronological record of the passing of individual days from a fixed moment in time” (Foster, 2002,

Earth’s galaxy, the Milky Way consists of more than 100 billion stars, many of which can be interpreted by human visual perception, while other can only be observed with the aid of a magnifying or light-collecting optical device such as a telescope. The stars are organized into various groupings according to their visible arrangement as observed in earth’s atmosphere. Human beings from cultures of eras bygone such as the Greeks, Romans, and Babylonians, and bestowed most, if not all of the titles upon the constellations as we know them today. Earth’s atmosphere comprises eighty-eight constellations, of which I have chosen the following five to discuss for my laboratory report: Andromeda, Big Dipper, Cassiopeia, Cepheus, and Draco
