Simulations Of Galaxy Formation

Anna’s typical workday would last from 3:00 P.M. to 6:00 A.M. As part of her observation preparation, she would visit with the observatory staff to discuss new findings and review what has taken place since her last visit. She stars by pulling out a list of dwarf galaxy stars, ordered by priority. She chooses the first star and asks the operator to move the telescope into position so that she can begin collecting starlight data. The article states that her research primary focuses on stars in ultrafaint dwarf galaxies. This article goes onto discuss that after the big bang, the first stars were formed from gaseous clouds. We know the big bang to be when the universe

Parenago 1802, a member of the ∼1 Myr Orion Nebula Cluster, is a double-lined, detached eclipsing binary in a 4.674 d orbit, with equal-mass components (M2/M1=0.985±0.029). Here we present extensive V IC JHKS light curves spanning ∼15 yr, as well as a Keck/HIRES optical spectrum. The light curves evince a third light source that is variable with a period of 0.73 d, and is also manifested in the high-resolution spectrum, strongly indicating the presence of a third star in the system, probably a rapidly rotating classical T Tauri star. We incorporate this third light into our radial velocity and light curve modeling of the eclipsing pair, measuring accurate masses (M1=0.391±0.032, M2=0.385±0.032 M⊙), radii (R1=1.73±0.02, R2=1.62±0.02 R⊙), and temperature ratio (Teff,1/Teff,2=1.0924±0.0017). Thus the radii of the eclipsing stars differ by 6.9±0.8%, the temperatures differ by 9.2±0.2%, and consequently the luminosities differ by 62±3%, despite having masses equal to within 3%. This could be indicative of an age difference of ∼ 3 × 105 yr between the two eclipsing stars, perhaps a vestige of the binary formation history. We find that the eclipsing pair is in an orbit that has not yet fully circularized,

Mayall’s object (also known as Arp 148) is the stunning result of an encounter between two galaxies resulting in a ring-shaped galaxy and a long-tailed companion, located almost 465 million light-years away within the constellation Ursa Major. The pair extends across 80 thousand light-years.

One astronomer, named Harlow Shapley, believed that the Milky Way, which is the region of space in which our planet is located, was much larger than previously thought. However, he thought that because it was so big, there were no other regions of space similar to our Milky Way. Another astronomer, named Heber Curtis, believed that the Milky Way was much smaller, but that there were other regions of space similar to it. Shapley ended up being right that the Milky Way was much larger than previously estimated, however, he was wrong about it being the only region of space, also known as a galaxy. Curtis was correct that there were other regions of space, or galaxies, other than our Milky Way.

The Tadpole Galaxy is a disrupted barred spiral galaxy that is 420 million light-years from Earth towards Draco. It has a trail of stars about 280,000 light-years long and big, bright blue star clusters. Numerous young blue stars and star clusters, created by the galaxy collision, are seen in the spiral arms, as well as in the long tidal tail of stars. Each of these clusters contains up to a million stars and will redden with age to become in time globular clusters similar to those found in essentially all halos of large galaxies, including our own Milky Way. It is said that a more compact intruder galaxy crossed in front of the Tadpole Galaxy and was slung around behind the Tadpole by their mutual gravitational attraction. During this encounter,

An accurate description of atomic processes governing the origin of elements in the astronomical objects is essential to understand the cosmic evolution of the universe. This project is one of the endeavors to accomplish this goal. Also, the knowledge of the atomic structure of heavy elements such as Krypton, Xenon, and Molybdenum is necessary to understand their interaction with the plasma in power generation reactors. New S2+ DR results may remove the anomalous behavior noticed by plasma modelers in its elemental abundance observed in the Orion Nebulae. Most importantly, this work will make my contribution as a woman in this male-dominating field and will inspire other women and me to take advantage of every opportunity come across to give

My brief required me to create a trading card game for a young novelist who is writing a science fiction action/adventure story name When Galaxies Cry. The cards were to be based around the ships in the story and needed to include and convey the aesthetics and features of the two prominent factions. The final practical would serve as a proto-type concept for a full game, which would act as promotional material and would include six cards; two for each faction and two upgrade cards. The two factions were the Alderith and Elixian Empire, each one having a unique aesthetic. Elixian ships needed to consist prominently of white and gold, and their overall shape was angular and geometrical. Alderith ships were grey with red detailing, and reflected a WW2/modern ship aesthetic. For inspiration, I studied a Japanese Sci-Fi ship designer Zenseava, whose designs are very reflective of the WW2/modern aesthetic I needed. When creating my own ships, I incorporated his use of line, colour, contrast and composition. This helped to create weapons, hull plating, wings, engines and cockpits that reflected the desired aesthetic.

The universe is cool. Just think about it, numerous items in this universe are cool. For example, Niagara Falls is so cool when the overflowing water comes rushing down. Also, the solar eclipse that happened this summer was cool. The eclipse occurred during the day and it became dark around 4:00 P.M. In a few states it was so dark the street lights came just like it was dusk. I didn’t even know the moon could cover the sun! The Milky Way galaxy is amazingly cool too. It contains over 200 billion stars. The Milky Way is a disk about 120,000 light years across with a central bulge that has a diameter of 12,000 light years. Most large galaxies have a supermassive black hole at the center, and the Milky Way is no exception. The universe has eight

The Milky Way is flat and disk shaped collection of gas dust and stars. It is 100,000 light years across and 7,000 light years thick. The Milky Way’s dish has two major spiral arms and two minor ones that comes together in of the galaxy. In the center of the disk is a cylinder bar that has a collection of old red stars. The Milky Way is visible on a moonless night only if you are in very dark spot where you would see a faint fuzzy glow in the sky. If Sagittarius and Scorpius are visible you notice it more. Galileo noticed that the Milky Way was made up of thousands of stars that were so close together, that you could see it with the naked eye and blend together to create a glow.

According to the International Astronomical Union (IAU) to classify an object as a planet it must have three qualities. One it must orbit a Sun or Star of some kind. Second it must big enough for gravity to compress it into a big round ball. And lastly it must be big enough to pull neighboring objects into the planet itself or sling-shot them around the planet and shoot them off into outer space. The place for my planet is in the Triangulum Galaxy. The Triangulum Galaxy is a spiral galaxy about 2.7 million light years (25761569076837520000km)away from Earth. The solar mass of the Triangulum Galaxy is 50 billion Mʘ (standard unit of mass in Astronomy). This galaxy has about 40 billion stars which is 1/5th of how many there are in the Milky Way Galaxy. And 1/25th 's of the Andromeda Galaxy. The name of my planet is Frigusodayin (Cold Air)(Latin, Armenian). The first rule of classifying a planet states that it must orbit a Sun or Star. The Sun my planet will orbit is called WASP-56. Some properties of WASP-56 are that this star has an apparent magnitude of 11.48. Apparent magnitude is the brightness of an object as seen from Earth. The higher the apparent magnitude the brighter it is (Our Sun 's is 26.7). This star is a G6 star which is part of the G-Type main-sequence star group. The G-Type main-sequence star is a main sequence star of spectral type G and luminosity level V. These types of stars have about 0.8 to 1.2 solar masses. Solar masses being the mass of a sun or star

A galaxy, also called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all bound to form a massive cloud in which we live in. Although it cannot be very well explained, dark matter makes up at least 90% of a galaxy’s mass.
