During the course of my vertical alignment assignment, I co-taught with Darlene Natson. The 4th grade classroom I taught in was Ms. Smith’s class. This was an introduction lesson to astronomy. During the course of the lesson, the standard that was covered was the following: S4E1. Students will compare and contrast the physical attributes of stars, star patterns, and planets.…
This type of star is very uncommon similar to the “B” and “A” stars. These stars get their energy from nuclear fusion, as they convert Hydrogen to Helium. As these massive stars begin to die once they’ve worn out their hydrogen and are now very old stars, they turn into giants/supergiants (old, large stars), resting just above the main sequence stars. This is where the “F” and “G” stars are located. The hotter they are, the brighter they are demonstrating the Sun being a G star.…
TRAPPIST-1 twice as old as our close planetary system 0 BY/ON 13 AUGUST 2017 SCIENCE Aug. 11 — Astronomers have limited in on a more exact gauge of the TRAPPIST-1 framework. Researchers trust the star and its exoplanets are in the vicinity of 5.4 and 9.8 billion years of age — as much as twice as old as our close planetary system. The sun was conceived 4.5 billion years back.…
my favourite constellation would be the Scorpius constellation, because that's my zodiac sign, and I love the way scorpio has made me the woman I am today, In Greek mythology, the myths associated with Scorpio almost invariably also contain a reference to Orion. According to one of these myths it is written that Orion boasted to goddess Artemis and her mother, Leto, that he would kill every animal on the earth. Although Artemis was known to be a hunter herself she offered protection to all creatures. Artemis and her mother Leto sent a scorpion to deal with Orion.…
Did you know that Sirius is also known as the Dog Star? Outshining all other stars in the February sky, it can be seen with the naked eye from any part of Earth. Of January's six constellations,Orion, the hunter, and Taurus, the bull are two of the most popular groups. In the constellation of Orion the Hunter is the Orion Nebula, one of the brightest nebulae in the sky, and the famous dark Horsehead Nebula. The famous Pleiades star cluster, also known as the seven sisters, located in the constellation of Taurus.…
The Life of Mercedes Richards My research is on this black African American astronomer Mercedes Richards. This astronomer love stars and studying on the history about them. When she was a little girl that’s all her farther would take her out to see was the beautiful stars floating in the midnight sky. But there is a certain kind of star Mrs. Richards studied in her system which is called Binary stars name after a prototype.…
Apparently, star beings are what the ancient people called the…
Storm brought his empty plate into the kitchen. He stood by the sink and watched Penny out in the patio. She stood back listening to the conversation between her mother and father, Arnold, and the two plump astronomers from ANU. She nodded her head politely and no doubt about it, gave polite chuckles at just the right time while they chatted on and on with each other.…
Many cultures throughout history have referenced to distinct patterns in the sky formed by stars. These patterns have been called many things but now scientists refer to them as constellations. Often times in our society we forget what a privilege it is to have tracking tools and measuring devices but 5000 years ago they used these constellations to track time and be able to tell where they are. Constellations have been seen as specific animals or figures that are then told with myths. STILL NEED TO FINISH…
Shaula is a hot subgiant star, but the star seems to be more of a hydrogen fusing dwarf. The estimated age of the star system is about 10-13 million years, and the surface temperature is 23,000. Its apparent magnitude of 1.62 makes it one of the 25 brightest stars in the sky and it’s estimated positon is 17h33.7m, Dec. - 37°06−. Its distance from the earth is about 300 light-years.…
a) I see White Dwarfs, Main Sequence (Dwarfs), Red Giants, Supergiants. b) White Dwarfs have luminosity from 0.001-0.02 and temperature from 7,000-24,000. Mass sequence have luminosity between 0.005-70,000 and temperature from 2,000-30,000. Red Giants’ luminosity is from 70-1000 while the temperature is from 3,000-5,000. Supergiants have luminosity between 100,000-1,000,000, temperature at 3,000-10,000.…
Summary Assignment #1 Sunspot Cycle: A Brief History In 1610, shortly after viewing the sun for the first time through a telescope, Galileo became the first European to observe sunspots, which are visibly darker, cooler areas on the sun. A little over 200 years later (in 1843), amateur German astronomer Samuel Heinrich Schwabe discovered that there is a cyclical, eleven, and by extension to a full cycle, twenty-two year pattern to the variation of sunspot counts known as the sunspot cycle. In 1848, Swiss astronomer Rudolf Wolf devised the following algorithm for making consistent counts of sunspots. [R=10g+f] Where “g” is the number of groups of sunspots and “f” is the number of individual spots.…
Joan Voute, an asronomer, determined that the star's trigonometric parallax is at 0.755 ± 0.028″. He also discovered that this star is relativly the same distance from the Sun as Alpha Centauri. At the time, proxima Centauri was considered to be the smallest-luminosity star. Analysis of…
The Search For Life on Other Planets/Moons For years and years scientists have had mars in their crosshairs when discussing life on other planets within our solar system. Now say we discover that mars is completely lifeless in every way possible. Is there any other possibility of life in our solar system? The answer to that question is in the moons of Jupiter.…
