A Sagittarius Triplet
A nebulae as described in Fraknoi’s Voyages to the Stars and Galaxies is “all objects that were not sharp points of light” (Fraknoi, page 384). The Sagittarius Triplet is a group of three nebulae’s famous for their bright red and blue hues, which is a main reason I choose this picture. There are three nebulae in this picture and each is spectacular on its own but together the Sagittarius Triplet creates a visual buffet for the eyes. The dark reds in particular are beautiful to behold and take up the majority of the visual landscape. These red colors are created by the emission nebulae by hydrogen gas that is heated by the intense temperatures of present stars. The image made me feel the vastness of space and the endlessness of time. The interesting layout of the nebulae creates a long stardust highway across the image, connecting the NGC 6559 and M8 nebulae. These three nebulae are so bright they are routinely featured in telescopic tours of the Sagittarius constellation and the central Milky Way galaxy. M8 or the Lagoon Nebula and M20 or Trifid were first cataloged in 1764 by Charles Messier (Kronberg).
The Trifid Nebula, M20, (at the upper right in the image) is a “rare combination of an emission and reflection nebula” (Koprolin). This colorful contrasting nebulae is 5,000 light-years from Earth and 40 light-years across. A star forming region in the plane of our galaxy, the Trifid illustrates three different types of astronomical nebulae; red
This nebula is about 1/3 of a light-year thick, and five light-years across. Most nebulae are shaped are more sphere shaped and most commonly a butterfly shape. Abella 39 is one extremely rare cases in which the geometry is much simpler. This star, unlike its usual common shape is in the form of a cat eye. This star is off center in the constellation about one tenth of a light-year.
Stars are the most recognized astronomical object in space and they represent the building blocks of galaxies. Stars distribute elements such as: carbon, nitrogen, and oxygen. A star develops from a cloud of hydrogen and helium, the dust clouds that are scattered throughout galaxies. An example of a dust cloud is the Orion Nebula. The gas and dust begin to collapse from its own gravitational pull. As the cloud collapses, the middle gets hotter. This is known as a prostar. A dense and hot core forms which begins to collect dust and gas. All this material may not end up as a part of the star but can become planets, asteroids, comets, or remain dust. A star about the size of our sun can up to 50 million years to mature. The smallest stars are
Curtis correctly noted that spectral lines could be seen within the spiral nebulae, and that they were generally consistent with the nebulae in the form of large assembled star clusters. These clusters supported Curtis's argument that these were in fact stellar systems, which are comparable to our Milky Way
- They are both made up of the same matter. There is three different types of bright nebulae emission, reflection, and planetary nebulae. And dark nebulae’s are known as “holes in the heavens”.
It is one of the most prominent and recognizable constellations in the night sky during its most distinguishable seasons, which is during the winter in the Northern Hemisphere, and the summer in the Southern Hemisphere (Orion). Orion’s belt is made up of the stars Alnilam, Mintaka and Alnitak, which are all the brightest stars of Orion. One leg is made up of the star Rigel. The second brightest star Betelgeuse, serves as the right shoulder, while Bellatrix establishes the left shoulder. The Orion's Nebula, which is a formation of dust and other gases, creates his sword which hangs from his belt. Orion is composed of many other nebulas and stars that create the beautiful display of Orion (Orion). There are many different stories of how the constellation was formed. One story tells of the love between Orion and Artemis. One day while Orion was swimming, Apollo dared Artemis that she couldn’t hit the distant object in the sea, which was really Orion. Artemis, not realizing it was her lover, shot Orion with an arrow. When she later realized her appalling fault, she honored Orion by placing him in the sky (Orion). In another story the hunter boasted that no animal could kill him. In response to this, Hera sent a scorpion to sting Orion. He smashed the scorpion with his club, but not before he was stung. The two are on opposite sides of the sky and cannot be seen at
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,

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
Original creation of the earth nebular hypothesis vs. six-day creation is the topic chosen for this article. The purpose of this paper is to discuss the difference between nebular hypothesis and the six day creation. The comparison is between old-earth and young-earth viewpoints on the original creation. Both views come from believers who are merely seeking truth and trying to understand God’s message.
The Carina Nebula is located in the Milky Way Galaxy in the constellation Carina in the Carina-Sagittarius Arm. It is sometimes referred to as the Eta Argus, referencing the former constellation, Argo Navis, which represented Jason and the Argonauts. It has been estimated at around 7500 ly (light-years) from earth. It was discovered in 1751-52 by Nicolas Louis de Lacaille and was later found to be one of the largest emission stars in the galaxy. Its entire mass is around 900,000 solar masses which is equivalent to 270 million pounds. It contains several open clusters of stars along with many O-type stars. It used to contain thousands of more stars than it does today, but many self-destructed. It is home to the Trumpler 14 and Trumpler 16
The Hubble sequence is also known as the “Hubble tuning- fork” because of the shape it is represented by. The Hubble scheme divides galaxies into three broad classes based in their appearance.
The first objects I observed were Albireo, two binary stars. They are about three hundredths to four hundredths and ten light years away. According to Stauffer Mark T from the American Psychological Association, “Albireo’s stunning colors provide a vivid contrast that has earned this double recognition as the most beautiful in the sky. Albireo is easily split using small telescopes at low magnifications, which show a smattering of background stars in addition to the double.” The binary stars known as Albireo is located in the midst of the Summer Triangle formed by Altair, Deneb, and Vega. Although most stars look similar as far color is concerned when observed with the naked eye, they vary in color. Research shows, the primary among the two binary stars is a rich golden orange while the fainter stars’ color resembles a clear sapphire blue light. Their color differences are not simply a contrast because it reflects their real color. According to James Mullaney from Sky & Telescope Media, “Albireo is a wide double; even a
Third, the observations of Novae. Shapley said that in certain lights obervées "novae" seen in the spiral nebula, implies that there is more light was far more nebulous. Curtis noted that these abnormal events pourait be a member of another class called supernovae today, they are referred to as during the debate "New Class".
The first thing you might be wondering is, what exactly is a nebula? Well according to Franknoi, a nebula is “A cloud of interstellar gas and dust that can be seen to glow with visible light or invisible light” (Franknoi 532). The Carina Nebula was formed approximately 3 million years ago in the Southern region of the Milky Way in the Carina constellation. It is located roughly 7,500 light years away from earth, which is relatively close in special terms, and even bright enough to be seen from south of the earth’s equator. It was discovered by French astronomer, Nicolas Louis de Lacaille, in 1751 from the Cape of Good Hope in
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.
