Compare And Contrast Rodia And Alderaan

During the first millennium B.C. scientists realized that astronomy had to become more scientific. Middle Eastern and Chinese cultures started studying the Sun, stars and the planets more closely in an attempt to learn more about our position in the universe.. Star positions also became important tools in understanding directions, and helping with navigation. One philosopher stated in 434 B.C. that the Sun was a ball of fire 60 kilometres in diameter, hovering 6500 kilometres above Earth’s surface. Around 130 B.C., Ptolemy wrote Almagest, which was a huge collection of astronomical data which included mathematical models, information about eclipses, and planetary and stellar positions and movements. It remained a major go to book for astronomy for hundreds of years, and was not seriously challenged until Copernicus disputed the geocentric model of the solar system in the 1500’s

These ancient stars that may hold the key to extraterrestrial life exists in the "halo" region of the Milky Way. NASA doesn't not have the technology yet, but if they ever do get out there, they will find stars old as 10 billion years

Humans have been searching for a habitable extraterrestrial planet before Galileo even assembled the first telescope. Since then, we have identified 1030 extraterrestrial planets, but only an esteemed handful of these copious supply of planets would even permit the hardiest of bacteria and single-celled organisms, let alone intelligent life. Kepler-452b is one of the most speculated planets yet discovered because it orbits within the Goldilocks Zone, or the perfect distance from its star so that surface temperatures of the planet remain stable for liquid water, and thus for life. Given that it is 60% larger than earth, takes 385 days to orbit its star, Kelper-452b exhibits almost every desirable characteristic of a habitable planet. However, it is a jaw-dropping 6 billion years old, or 1.5 billion older that our own sun.

Star Wars and Star Trek, two universes set in space. One is set in our galaxy and those closes by, the other in a galaxy far far away. They use different types of weapons and ammunition. One universe uses ships with several crew members, while the other uses one-man ships as well as ships with multiple crew members. The number of races and planets between the two universes is vastly different. Also, one is more popular than the other. Both of these universes are similar in concept, but Star Wars has better weapons, races, and more creativity in general.

Vera Cooper Rubin was born July 23, 1928 in Philadelphia, PA. Her father was Philip Cooper, an electrical engineer, and her mother Rose. She first developed an interest in astronomy at the age of 10 while stargazing from her home in Washington D.C. Her father encouraged her to follow her dreams and took her to amateur astronomer meetings. She earned her Bachelor’s degree from Vassar University in 1948 of which she was the only astronomy major that year. Later she earned her master’s from Cornell in 1950 with her masters’ thesis was controversial and centered around the possibility of bulk rotation by looking for “sideways” motion of galaxies. She finally got her Ph.D. from Georgetown University in 1954. Her doctoral

Star Wars and Star Trek have been one of the most popular series invented. For many years now people have gone to events called comic-cons. These events are where people dress up as a character of their choice and do activities. These two subjects that were chosen for this compare and contrast essay were picked out by a birthmark. A birthmark on me myself that looks like the Star Trek symbol. This birthmark has led me to want to know a little more about these two popular movies.

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,

Annie Jump Cannon was most famous for developing a star spectra that is still used today. Many astronomers remember the order of the star spectra by “Oh Be A Fine Girl Kiss Me” (Annie Jump Cannon theorist of star spectra, n.d.). Some people call her the “The Census Taker of the Sky” (drfate0000,2014),and cataloged many stars in her lifetime (Census taker of the sky, 2014). She rearranged Pickering’s order for the star spectra (Annie Cannon, 2015). She examined and classified bright southern hemisphere stars (Annie Jump Cannon theorist of the star spectra,

Most people in their lives have seen a shooting star and exclaimed, “Make a Wish!” However, this so called “shooting star” is actually the clue to how the solar system was created. While this rock object is in space it is called a meteoroid, and then it is called a meteor when it enters a planetary atmosphere. The friction of the meteoroid created by the incoming velocity causes it to heat up quickly, and in result a bright flash of light. As noted above, this is what people see when watching the sky. In addition, meteorites gave the first knowledge about abundances of chemical elements in the solar system in the 1930s through 1950s. Meteorites are the most ancient rocks known to mankind and have helped pave the way in the study of the formation

Several unresolved problems remain concerning the Orion Nebula. The fate of the protoplanetary disks, for example, is presently impossible to predict. Without a more detailed understanding of how planets actually form, it cannot be assumed that the events within the Orion Nebula are analogous to the events that led to the formation of the planets in the solar system. Furthermore, the detection of water in the nebula has revealed the need to revise the theory of star formation to

While the age-old question of “Star Wars or Star Trek?” is based on personal preference, there are many similarities and differences between the two. Star Wars, though it has a larger fan base, is not necessarily the reigning champion when it comes to storylines, nor is Star Trek the winner with its scientific background and hopeful prospects of the future. Sci-Fi, or science fiction, has been a genre that has fascinated the masses for generations. Having had the space race end in 1957, the space travel frenzy that ensued was the beginning of a Sci-Fi nation. Star Trek’s television series, The Original Series was fairly successful, while Star Wars’ A New Hope was a smashing success, bringing in millions of dollars and twice as many fans. Star Trek’s The Next Generation and Star Wars’ A New Hope have as much in common as they have in opposition. Star Trek and Star Wars, though both extraordinary on their own, have many similarities and differences such as plot, character diversity, and special effects.

Distributed over 90 sq. deg. of the sky, they lie from 4 to 23 kpc from the Sun. The most significant group of RRLS is the Virgo Stellar Stream which is composed of at least 10 RRLS and 3 BHB stars. It has a mean distance of 19.6 kpc and a mean radial velocity Vgsr = 128 km/s, as estimated from its RRLS members. With the revised velocities reported here, there is no longer an offset in velocity between the RRLS in the VSS and the prominent peak in the velocities of main-sequence turnoff stars reported by Newberg et al in the same direction and at a similar distance. The location in phase space of two other groups suggests a possible connection with the VSS, which cannot be discarded at this point, although the turnoff colors of the VSS and group H, as identified from Newberg. Two more groups are found at mean distances of 19 and 5.7 kpc, and mean radial velocities of -94 and 32 km/s. None of our groups seems to relate to streams. The excess of stars observed in Virgo appears to be composed of several halo substructures along the same line of

All research, authored by Professor Rory Barnes is published in the latest issue of Astrophysical Journal, and the data names the new metric “the habitability index for transiting planets’. Barnes, professor of astronomy and the University of Washington, declares that he and his team have conceived a way of taking all observational data available to develop a system that would help astronomers decide which planets, of the hundreds suspected of life sustainability, is actually worth the attention.
