The Hertzsprung-Russell Diagram Stars that are located high on the y-axis are very luminous, and have a very large diameter. This is the realm of the giants on the H-R diagram. They are massive stars, but it is their great size (some have a radius more than 1 000 times the sun's, which is appr.

Orion Nebula The nebula is visible with the naked eye even from areas affected by some light pollution. It is seen as the middle star in the sword of Orion, which are the three stars located south of Orion's Belt.The star appears fuzzy to sharp-eyed observers, and the nebulosity is obvious through binoculars or a small telescope.he Orion Nebula contains a very young open cluster, known as the Trapezium due to the asterism of its primary four stars. Two of these can be resolved into their component binary systems on nights with good seeing, giving a total of six stars.

The Dazzle of the Southern Sky The Dazzle of the Southern Sky Constellations like Sagittarius and Scorpius are best seen in the Southern Hemisphere; the latter lies within the center of the Milky Way, high in São Paulo’s sky. It is possible to see the scorpion from its sting to its claws, including the red supergiant star Antares at its heart.

- Spica (Alpha Virginis) is the brightest star in the constellation Virgo. It is actually a binary star, comprising of two close orbiting stars.The primary has a spectral class of B1 and the secondary B2.They are both blue giants.pica (Alpha Virginis) is the brightest star in the constellation Virgo. It is in fact a close binary star system so it is impossible to resolve individual stars through a t … elescope. It is approximately 7.4 times larger than our Sun. So it has a radius of about 5,150,400 km.

Populations I and II Stars Populations I and II Stars. Stars may be classified by their heavy element abundance, which correlates with their age and the type of galaxy in which they are found. Population I stars include the sun and tend to be luminous, hot and young, concentrated in the disks of spiral galaxies. They are particularly found in the spiral arms.

- Here are your two problems: * Purchase price : Cheap <<<<. * Where it was purchased : Ebay <<<. Dont get me wrong i love cheap ebay parts. But i would not buy turbos, clutches, suspension from them. They are good for non moving low stress things, intercooler piping, hoses, exhaust (not manifolds) etc. Reply With Quote.

- Almost everyone is familiar with sea stars. Together with their relatives, these decided 'stars of the shores' are echinoderms. Some kind of echinoderm can usually be found on all our shores. The richest variety of echinoderms appear to be found on our Northern shores such as Changi and Chek jawa.

- Some astronomers think we might actually just have two arms, Perseus and Sagittarius. The Sun is located in the inner rim of the Orion Arm, which is thought to be an offshoot of the Sagittarius Arm.The Sun is located about 26,000 light-years away from the center of the galaxy.Before telescopes, the Milky Way just looked like a bright area in the sky, but when Galileo first turned his telescope on the region in 1610, he realized that it was actually made up of faint stars.he astronomer Harlow Shapley accurately determined where the Sun is in the MIlky Way in the early 20th century by noticing that globular clusters were uniformly located above and below the Milky Way, but they were concentrated in the sky towards the constellation Sagittarius.

Pleiades The Pleiades, are an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. A faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster, but is now likely a

Betelgeuse The Star Betelgeuse is a red supergiant star of spectral and luminosity type M1-2 Ib. The star may have between 12 and 17 times Sol's mass (ESA), over 650 times Sol's diameter, and around 40,000 to 100,000 times its bolometric luminosity.etelgeuse is the bright, orange-colored star in Constellation Orion, at top left (another image with enhanced colors). Like many of the stars of Orion, it was probably formed a few million years ago from the molecular clouds observed in Orion but has evolved rapidly due to its unusually high mass.

Carina Nebula The Carina Nebula is a bright, large emission nebula surrounding the star Eta Carinae, located in the southern constellation Carina. It is also sometimes called the Eta Carinae Nebula, the Grand Nebula, or the Great Nebula in Carina. The nebula’s designation in the New General Catalogue is NGC 3372. It is one of the largest diffuse nebulae known, one that contains several open star clusters.

The Stars of the Milky Way Our luminous galaxy, however, appears to be embedded in a larger and much more massive, but unseen, spheroidal halo of nonluminous material. The Milky Way may actually contain as much as the mass of a trillion suns like Sol, although the 400 billion, estimated luminous stars mass only about 175 billion suns.

Globular cluster Of the globular clusters within the Milky Way, the majority are found in a halo around the galactic core, and the large majority are located in the celestial sky centered on the core. In 1918, this strongly asymmetrical distribution was used by Shapley to make a determination of the overall dimensions of the galaxy.

Constellations Scorpius, the Scorpion. Three bright stars form the head of Scorpius, the celestial scorpion, while its tail curves away below it in the southern sky of summer. The brightest star in Scorpius is Antares, which is in the middle of the scorpion's curving body. This brilliant red star is one of the behemoths of our stellar neighborhood. If you placed it at the center of our own solar system, it would swallow Mercury, Venus, Earth, and Mars, and almost reach Jupiter.

Mystery of 'Monster Stars' of the Large Magellanic Cloud: Solved The Large Magellanic Cloud (LMC), at a distance of 160000 light years, is the third nearest satellite of the Milky Way galaxy we live in and contains around 10 billion stars. The LMC has many star forming regions, with by far the most active being the 1000 light year diameter 'Tarantula Nebula' where the four supermassive stars are found.

- The Sirius Myth. You might be wondering where we got our name, Sirius Publications(tm). The name derives from the star known as Sirius. Look below for more information on the facts, mythology and mystery of Sirius. Facts/Astronomy Mythology Literature Facts: Sirius is located in the constellation Alpha Canis Majoris. It is the brightest star in the night sky, with 22 times the luminosity of the sun. Canis major is at the heel of the constellation Orion. Sirius is bluish-green and very large, and is close to Earth (Distance in Light Years 8.60 ± 0.04, one of the nearest stars). Sirius is also known as the Dog Star. Sirius is closest to the Earth in Summer, especially July and August.

Number of Stars in the Milky Way Stars are located in galaxies, but a galaxy contains more than just stars. Clouds of dust and gas, called nebulae, are where stars are born. In our galaxy alone, the Milky Way, there is a predicted 3 billion to 100 billion stars.

The Supermassive Star Betelgeuse --Will Its Violent Death Impact Earth? (Today's Most Popular) Betelgeuse is about 600 light years distant. Betelgeuse, one of the most luminous stars known and ten times the size of the Sun, is thought to be only 10 million years old. The more massive a star is the shorter its lifespan, which is why astronomers think it has an outside chance of exploding relatively soon.

General Astronomy/Print version Betelgeuse is a classic example, a bright red star in orion, visible to the naked eye, and which has a diameter 630 times that of the Sun and 14 times as massive. The example pictured above is a supergiant 500 times the diameter of the Sun and about 12 times as massive.bove left, a look at the structure of a supergiant. Outside the hot central region, the envelope of the star is convective and probably turbulent. (Convection is the mixing of fluid as hot fluids rise and cooler fluids sink.
