Elliptical galaxy

Q7) Describe how emission line spectroscopy is used in astronomy for the evaluation of star composition light years away from Earth. Please provide detailed information. The spectrum of stars consists of bright lines and dark lines. These lines are produced when the star emits or absorbs energy at specific wavelengths. Emission line spectroscopy is used in order to find out the star’s colour spectrum. The spectrum can be found by using a visible light telescope or by collecting radiation that…

Part of your most recent plan was to be here now, you chose this human existence that you are currently experiencing, you pre- planned every detail of your life in order to gain the maximum learning and adventure, and you choose to exit when you have completed all the experiences you planned for yourself. The world away from this world (the universe) is not separate from us, it is not some far away mystery; it is a logical, functioning, populated, progressive, divine place! Much like here on…

every single day. Gravity has a huge impact on these discoveries. We know that gravity impacts the solar system in many ways and all throughout the galaxy but how does gravity affect these things? All objects have a gravitational pull. This means that this force had a huge impact on the formation of our solar system and other solar systems in our galaxy and in the universe. First of all, a phet simulation showed us this. When mass 1=50 kg and mass 2=200 kg, the gravitational pull was 41712 E-7…

The paradox Olbers Heinrich Wilhelm Olbers German astronomer by 1826 in formulated physical paradox that was previouslyJohannes Kepler (1610 in), and Halley and Cheseaux (the 18th century described) as well. The paradox is that if the universe is infinite, we'd have an infinite number of stars light of the result The combination of the sky at night it should be clear to all.However, experience to the contrary. [1] Assumptions [edit | edit source text] If 1. the universe is infinite, 2. an…

Astronomers discovered a galaxy 9.8 billion light years away that creates an astounding 800 stars a year. To put this in perspective, the Milky Way produces two stars per year at most. “It is very exciting to have discovered such an interesting object,” said Gillian Wilson, a professor of physics and astronomy at the University of California, Riverside and a member of the research team. “Understanding its nature proved to be a real scientific challenge which required the combined efforts of an…

of this is the following: the nearest galaxy to the Milky Way is called the Andromeda Galaxy. It is just over two and a half million light years away, which means that the light we see from there is just over two and a half million years old because this is the distance between us and the Andromeda Galaxy. Now imagine those numbers written out. Wait, don’t even attempt it, I’ll write them for you. The nearest galaxy to our Milky Way is the Andromeda Galaxy. It is just over…

John Sinclair Dr. Philip Carlson General Physics I 11/28/2015 Physics Worldview Paper 6.67408 × 10-11 m3 kg-1 s-2. This number is the universal gravitational constant. It is an empirical physical constant denoted by the capitol letter G. The gravitational constant was first used in Newton’s law of universal gravitation [1] which states that any two bodies attract one another with a force which is directly proportional to the product of the two masses, and inversely proportional to the square…

In the endless reach of the universe, there was a star known as Arcturus. One day, she fainted and was taken to the hospital. The doctor diagnosed her with “Red Giant Star" syndrome, an outcome of her being with an iron child. The doctor advised her that due to her condition, if she chose to continue to fuse silicon into iron- to nurture her iron baby- she would get too hot and she could potentially collapse. Back in the day, Arcturus was able to combine hydrogen into helium particles in a…

Originating from cosmic events such as supernovas, chemical elements are the foundation of all life. Billions of years ago, a violent explosion known as the Big Bang produced helium, hydrogen, and all of the matter and energy in the universe. Generated in the cores of stars, nuclei combined to form atoms which constitute the basic unit of all chemical elements. The extensive expansion of the universe induced the birth and demise of more stars and consequently the creation of more elements.…

Uranus is the seventh planet of our Solar System for which scientists have about information due to the distance from this planet and Earth (a minimum of 1.6 billion miles [51]). Up until recently, our ability to observe it from afar was near non-existent. This icy gas giant experiences periods of day and night which last for 42 Earth years due to its 110 degrees axis tilt [14]. Uranus is not as stormy as Jupiter or Saturn, but within the 'Spring' section of the plant, where both cold and warm…
