Located in the southern hemisphere, it was included in Ptolemy's 48 constellations in the second century, and is recognised among the 88 today. It contains 8 main stars and has 32 stars with Bayer/Flamsteed designations. These unseen stars come from a cluster known as M41 which is about 2,300 light years away. Even a small telescope will reveal the swarm of several thousand stars just under Sirius. Canis Major's second-brightest star is Adhara, placed within the Dogs leg. Adhara is 425 light years away, and were it to be the same distance from the Earth as Sirius, it would shine 200 times brighter. Also, if our eyes were tuned to Ultraviolet light, Adhara would outshine every other star in the sky due to it emitting more UV rays than visible …show more content…
It's 8.6 light years away which is only twice as far as our closest stellar neighbour. It may not contain the most stars, spread the furthest across space or be the easiest the locate, but it's a part of something bigger. Sirius is actually a double star, labelled Sirius A and Sirius B, a binary star which is not seen as one by the naked eye. While Sirius A is a white main-sequence star of spectral type A1V, Sirius B is a a faint white dwarf companion of spectral type DA2. Sirius A is around 20 times larger than the Sun and 25 times more luminous as well. Sirius B used to be a Red Giant which became unstable and ejected its outer layers of dust and gas as a planetry nebula. This left behind a hot, dense solid core - a White Dwarf. The jewel inside the rock had been revealed. Sadly the White Dwarf will continually fade away but Sirius itself is gradually moving closer to the Solar System. This means it will slightly increase in brightness over the next 60,000 years. The distance will begin to recede after that, however it will continue to be the brightest star in the Earth's sky for the next 210,000
In using this allusion, Frost not only continues the "poetic tradition" but adds all the depth of meaning of Keats' poem to his own. The star doesn't want much of us -- only to stay above us. He says that "when the mob is swayed" or when social, political, or moral upheaval takes place and the norm is to be radical, the star likes being above it all, condescendingly regarding the earth. When this happens, we should "choose something like a star" and concentrate on it.
Perseus, or “the hero,” has twenty-eight stars. The brightest, most recognizable ones are Mirfak and Algol. Mirfak is the brightest star of Perseus. It is a little bit brighter than Polaris, the North Star. Algol is the most famous star. In the constellation, Algol is the eye of Medusa, translating to “demon star.” People used to think that Algol was cursed due to its constant change in brightness, but we know today that sometimes another star overlaps Algol, causing its magnitude to appear to change. Perseus has six stars with confirmed planets. (Coder pp. 85 & 87, Fanshawe, Perseus Constellation, Perseus Hero)
It’s a white giant and has a temperature of 7700 Kelvin. It’s a type A star that is 8.5 times brighter than the sun. It is most likely to be in the last stage of ordinary star-type life. Scientists are saying the sun’s older twin is found in the middle of Capricorn. Studying this star will help them see how the Earth’s sun will develop.
Alpha Centauri (α Cen) is our solar system closest star neighbor. There are three stars in the system: Alpha Centauri A, Alpha Centauri B, and Alpha Centauri C or Proxima Centauri. To the unaided eye, Alpha Centauri A, Alpha Centauri B look like one of the brightest stars in the night sky to help form the constellation Centaurus. This star system resides at 4.37 ly (1.34 pc) away from us. But
Sirius B is a white dwarf star and it is a star system, the brightest star in the Earth's night sky. One fact is that it is the closest white dwarf to Earth. Sirius B began its life as a blue star with 5 times the Sun's mass, say astronomers. It basically swelled into a red giant and shrank into a white dwarf. If this blue star still was shining today, Sirius would be so bright it would cast shadows on Earth. Also it has the same mass of the sun. All in all, the white dwarf, Sirius B, is a very bright star that shrunk from a main-sequence star.
They’re carbon stars, a unique type of variable star, which accumulate soot in their upper atmosphere that scatters light near the blue end of the spectrum. What’s left for us to view is the red component of a star’s light. As the carbon particles build up, the star fades in brightness and gets even redder. Eventually, the carbon absorbs enough radiation to escape the star, and the cycle starts over again.
This is a transmedia effort by the movement Half The Sky. It's a movement addressing the challenges facing women and girls globally with things such as sex trafficking, forced prostitution, gender based violence, maternal morality and poverty. The movement has a book of the same name, a PBS series, and Facebook and mobile games which allows the spread of their message and for others to share
This paper is an overview of the Kepler spacecraft and its mission in space. According to the National Aeronautics and Space Association (NASA), Kepler, named after Renaissance astronomer Johannes Kepler, “is a space observatory launched…to discover Earth-like planets orbiting other stars.” Kepler does this by searching for planets within our galaxy that have a similar size to Earth within a habitable zone. A habitable zone is a distance between the planet and its star where water can exist on the planet’s surface. Additionally, Kepler is aimed at searching for planets with similar one-year orbits like that of Earth. As technology advances on Earth, increased standards of living and life expectancies have taken a toll on Earth’s fleeting, finite resources. Kepler potentially provides scientists with information regarding planets that can serve as a future home when resources have diminished and information that can foreshadow inevitabilities about Earth through older, Earth-like planets.
The Orion Nebula is one of the closest stellar regions to the Earth. Using parallax measurements, it has been estimated that this nebula is only 1,500 light years away. In addition, the Orion Nebula is a relatively young star cluster, with an approximate age of less than one million years. It has even been speculated that some of the younger stars within the cluster are only 300,000 years old.
I was born with an inherent fascination for all things celestial. Ever since I was young, I have been staring at the night sky trying to find constellations, or using my juvenile imagination to create my own. My efforts to find, view, and mentally catalogue everything the heavenly bodies have to offer has led me to employ some over-the-top measures, but the most extreme of them all might be the night I stayed awake through the wee hours of the morning to catch a glimpse of a meteor shower. Over the course of an entire year, the memory of this stupefying event is still as lucent and vivid as it was that very night so long ago.
During June 1889 an artist known as Vincent Van Gogh created the famous painting Starry Night as a night effect inspired piece it brings influence and adventure to people everywhere. During this time the style of the expressional night painting was so new it was looked down upon in its time as a childish piece while every ones almost pictures have portraits of landscape where the big hits. Since Van Gogh overcame what most artists, and all creative people have to, to become truly magnificent. He got over the fear of being wrong, as well as the ability to play around a lot. Because when you're fully making your imagination come true it has to be in focus.
The Sun is a huge, bright sphere that is mostly made up of gas that is about 5 billion years old. The Sun is the closest to the Earth, it is 145 million km distant (this distance is called an Astronomical Unit). The next closest star is 300,000 times further away. There are probably millions of similar stars in the Milky Way galaxy (and even more galaxies in the Universe), but the Sun is the most important to us because it supports life on Earth.
In Bright Star, Keats utilises a mixture of the Shakespearean and Petrarchan sonnet forms to vividly portray his thoughts on the conflict between his longing to be immortal like the steadfast star, and his longing to be together with his love. The contrast between the loneliness of forever and the intenseness of the temporary are presented in the rich natural imagery and sensuous descriptions of his true wishes with Fanny Brawne.
The Andromeda Galaxy being 220,000 light years across is the biggest of its local galaxy group which includes the Milky Way Galaxy, Triangulum Galaxy, and about 44 smaller galaxies. The Andromeda Galaxy contains about (1 trillion*10to the 12th power) stars, which is more then double the estimated 200- 400 billion stars located in our own Milky Way Galaxy. Along with this the Andromeda Galaxy has a brightness magnitude of 3.4 making it one of the brightest of all the Messier Object group.
The education system in India is based on forced learning that kills student’s spirit and zest of learning. In the film “Like Stars on Earth,” we look specifically at the draw backed role played by parents and teacher in Indian education system. We follow the story of a dyslexic Indian boy, Ishaan, who always had trouble coping with his studies, but in the end with the help of an understanding teacher he is able to study normally and catch up with his peers. We will analyze this film using the concepts from Practices of Looking to explain our thesis. Eddie will cover the concepts of encoding and the ideology surrounding Indian education; Kiranjot Singh will explain the concepts of punctum, negotiated reading and producer’s intended meaning;
