In 1935 the lands of Richmond Hill became home to the world’s second largest telescope. Jessie Donald Dunlap funded the David Dunlap observatory, DDO, in the memory of her husband Alexander Dunlap. These 189 acres of land were given as a gift to the University of Toronto. For years it has been a helping hand leading towards solar and lunar discoveries. July 2008, The University sold this to a company called Metrus. The DDO has been apart of the community for 76 years and without a doubt should be
In this semester, we have visited three public art agencies of NYC, which are the Percent for Art Program, the MTA’s Arts for Transit program, and Creative Time. These public art organizations commission public art to the public. They integrate and apply arts to sites through process and research based on artists’ practices. Public art agencies have similar goal that is to put artworks in appropriate sites and to get response from audiences. In this paper, I will discuss the three agencies we visited
black hole, in astronomy, celestial object of such extremely intense gravity that it attracts everything near it and in some instances prevents everything, including light, from escaping. The term was first used in reference to a star in the last phases of gravitational collapse (the final stage in the life history of certain stars; see stellar evolution), by the American physicist John A. Wheeler. Gravitational collapse begins when a star has depleted its steady sources of nuclear energy and can
Constellations are patterns of groups of stars in the sky. They have been around for a long time, and most people know of the most common ones, especially the zodiac constellations. I find constellations interesting because I always liked trying to find them in the night sky, and I have always wondered how they came about. Constellations have an important history that many do not know about. Constellations have been around for over 3000 years. No one knows who invented them, however astronomers believe

start emitting x-rays which can be detected and observed from Earth (Netting 2014). Studying x-ray binaries are an excellent way to detect stellar black holes as binary systems provide sufficient matter to supply the black hole’s x-ray emissions. Cygnus X-1 is an example of a black hole detected through the observation of a binary x-ray ... ... middle of paper ... ...leted of its nuclear fuel and lost its outer layers.

physicists R. Oppenheimer and H. Snyder, in 1939, realized that Schwarzchild theory was only possible if the star was much bigger than our sun; approximately 3.9 times or larger. In the early seventies, a x-ray source was located in the Constellation Cygnus. The x-ray source couldn't actually be precisely located but was narrowed down to a relatively small area. At this time it was very puzzling for the scientist. Steven Hawking, in the seventies, came up with theoretical arguments demonstrating that
material whirling about the center, the object is approximated to be about 3 billion times the mass of our Sun and appears to be concentrated into a space more meager than our solar system. For many years, X-ray radiation from the double-star system Cygnus X-1 convinced many astronomers that the system
Have you ever wondered how a black hole is formed? Black holes have an interesting history. Black holes actually help us clean the universe by sucking up all the garbage in the universe. A black hole is formed from a big sun when it collapses on itself and it becomes a black hole. An astronomer from germany by the name of Karl Schwarzchild tried to theorize how a star can shrink into something he called black hole. He guessed that our sun would have to shrink less than 2 miles its size. There are
rushing to fill a void created by the defunding of the space exploration division of NASA is almost a guarantee. If, with a budget only a small fraction that of the NASA space exploration budget, and a few great minds, private companies like SpaceX, Cygnus, and Virgin Atlantic can make such huge advances in space flight and research; how much more could they accomplish if they were not forced to compete with an over bloated, non-essential, and stagnant government bureaucracy. Though I may never reach
While studying the solar system in our eighth grade science class, we were each assigned a constellation to research. The constellation that was assigned to me was Cepheus. In this paper my goal is to explain the myth behind this constellation and describe its features. To achieve my goal, I have organized my paper into three main sections, one of which has sub-sections. In the first section, I will explain the Greek mythology that is associated with the constellation Cepheus. In the second
5 feet tall, weighing up to 31 lbs and with a wingspan of up to 10 feet, the California condor (Gymnogyps californianus) is one of the largest flying birds in Northern America. Surpassed only in weight and wingspan by the Trumpeter (Cygnus buccinator ) and Mute (Cygnus olor ) Swan. The California condor has an average life span of 60 years, with some documented ones surpassing 80 years; it is also one of the longest living birds. Recognized by its size, bald head and large white patches under their
Cepheus belongs to the Perseus constellation family along with Andromeda, Cassiopeia, Cetus, Lacerta, Pegasus, Perseus, and Triangulum. His neighboring constellations are Andromeda, Cassiopeia,Cygnus, Draco, Camelopardalis, Lacerta, and Ursa Minor. The myth behind Cepheus is interesting, the problems in the story were self inflicted because they were disrespectful; so the myth teaches the lesson of obedience. Cepheus' myth is pretty cool because
nebula, Abell 39. Lying about 6,800 light-years away, Abell 39 appears as an almost perfect sphere, one with a radius spanning approximately 2.5 light-years. Hercules belongs to the Hercules family of constellations, along with Sagitta, Aquila, Lyra, Cygnus, Vulpecula, Hydra, Sextans, Crater, Corvus, Ophiuchus, Serpens, Scutum, Centaurus, Lupus, Corona Australis, Ara, Triangulum Australe and Crux. Constellations directly bordering Hercules are Draco, Bootes, Corona Borealis, Serpens Caput, Ophiuchus
from the host star, inside the habitable zone. This is the locale around a star inside which a planet can support fluid water on its surface given the right atmospherical conditions. The Kepler-186 planetary framework lies toward the heavenly body Cygnus, something like 500 light-years away. (planet Astronomy space explora) Figure 1. Kepler-186f is within ten percent the size of Earth. At one time, a little number of Earth-sized planets, for example Kepler-20e, has been uncovered. However, all formerly
many questions, it has also introduced hundreds more. There is believed to be a black hole at the center of our galaxy, the Milky Way galaxy. Black holes were first proven to exist in the 1970’s when a few scientists identified a black hole called Cygnus X-1. Since then, an intense amount of study has been dedicated to discovering the various properties of black holes. Merriam Webster defines a black hole as: a celestial object that has a gravitational field so strong that light cannot escape it and
black holes are formed then it will blast a hole in the side of the wall that we call black hole theory. Black holes are rather mysterious creatures, we rarely see them, but they are always there. The first black hole that was discovered was Cygnus X-1. This black hole was only an ordinary small size to us today, but back in 1970, it was
AZ and a few mile south of Interstate 8 is about 90 miles southwest from my home. My friend Jim Stevens had brought his 17-1/2" Dobsonian. We started the evening observing some of the Messier objects such as the Veil and North American Nebulae in Cygnus, when Jim said " Let's look at some of the globulars in Sagittarius." We started our tour with M22 and M28, observing at 50X and then at 180X. Around 11:00 local time, we had M-70 in the field when Jim went to the charts to determine the next object
While looking in the sky at night, you try to point out the different constellation you see. Most people know the major constellations, but many do not know about the constellation Delphinus. There are many scientific and literary explanations for the constellation Delphinus. There are two known myths about delphinus. The first is about Arion. Arion was a known poet and musician. He was born on the island of Lesbos. He was known for playing the lyre. This made him famous during the seventh
Cygnus ‘The Legend’ said that appearance is not everything but everything is begun from appearance. Good appearance will be the good beginning. If our appearance is neat, clean, match, and fashionable with our style; we will be lucky, we have friends in
