early observational work soon focused on the search for pairs of stars that were very close together visually. Astronomers of the era expected that changes over time in the apparent separation and relative location of these stars would provide evidence for both the proper motion of stars and‚ by means of parallax shifts in their separation‚ for the distance of stars from the Earth. He soon discovered many more binary and multiple stars than expected‚ and compiled them with careful measurements of their

Employee Recognition and Reward Program HRMG 5000 Human Resource Management Abstract I believe that a robust employee recognition program can/will increase employee satisfaction and increase the organization’s customer service rating. In the past‚ employees were recognized according to their section leadership. Some were recognized and others were not. Since the implementation of the group wide recognition program‚ I believe the employees are happier. I will

The Sun is just an ordinary star‚ and that’s true because there are many others similar to it but there are smaller stars than larger ones; The Sun is on the top 10% by mass. The Sun is about 70% hydrogen and about 20% helium. Everything else like metals is about less than 2%. This changes as the Sun turns hydrogen into helium in its core. The radius of the giant star is 432‚288 miles‚ while the mass is 1.982 x 1030 kilograms. Atmosphere

CHRISTIAN HUYGENS Huygens was a Dutch scientist. He lived from 1629-1695. He proposed the earliest theory about the nature of light‚ a phenomena that puzzled scientists for hundreds of years. His improvements on the telescope allowed him to make the first observations of Saturn’s rings and to discover its moon‚ Titan. CARL SAGAN Sagan was an American astronomer. He lived from 1934-1996. He may not have been a great scientist in comparison to others‚ but he is one of the most

This supports the fact that Andromeda is not an open or globular cluster in what is known as our own Milky Way galaxy. Andromeda is the biggest by volume what astronomers

Yet despite its unassuming appearance‚ M 31 is immensely greater than the stars that surround it. For centuries‚ astronomers thought that the Andromeda galaxy

Exoplanet Survey Satellite‚ TESS‚ wich will be sent to orbit on 2017 with the mission of finding exoplanets. Exoplanets are planets that orbit a star that is not our sun‚ and until now scientists have discovered over 800 of them‚ mainly thanks to the Kepler telescope wich began working in 2009. TESS goal is to identify planets within the habitable zones of nearby stars. This mainly means planets with a solid crust and with temperatures that allow the existence of liquid water. These are planets that could

The star shoud provide brightness and warmth to the planet‚ be the energy source that lets plants make food to feed organisms. It is also important in that it will create seasons‚ weather patterns‚ oceanic currents and even sleep patterns for most living organisms. However‚ the planet should be a distance from the star that results in it achieving a suitable temperature so its

this lab was to introduce us to star charts and how to use them to find stars‚ constellations and other bodies in the sky. Procedure: The instructor gave a brief but thorough lecture and demonstration on how to go about finding the answers on the worksheet. We then filled out the worksheet that cover finding stars and constellations using right ascension and declination in general and on specific dates‚ where constellations are in the sky in relation to the star Polaris‚ and what time the sun
