NGC 3567

NGC 3567 is an HII region located about 9,000 light years away towards the constellation Carina, not far in the sky from Eta Carinae, in the Sagittarius arm of the Milky Way. It spans about 100 light years and is illuminated by gas ionized by young stars created by episodes of star formation in the region.

HII regions are regions where hydrogen gas clouds condense and trigger intense star formation. The young, massive stars these areas contain emit huge amounts of ultraviolet radiation, ionizing the surrounding hydrogen and giving the regions their name. NGC 3567 is very dense, demonstrated by the dark, opaque dust in the center of this image. This can make it difficult for astronomers to see the young star clusters. So far, not enough star clusters have been found to explain the nebula’s brightness.

This is the Sagittarius arm of the Milky Way galaxy, shown mostly with optical data from the European Southern Observatory. The x-rays Chandra detected, shown here in blue, likely arose from wind blowing from young stars, according to NASA. This image comes from 2005 and shows objects about 9,100 light-years away.

Carina Nebula

The Carina Nebula, NGC 3372, is a star forming region located about 7,500 light years away in the Sagittarius-Carina Arm of the Milky Way. It is over 300 light years away, one of the largest star forming regions in our galaxy. Over 14,000 stars have been located within the region.

The region includes Trumpler 15, an area with a deficit of X-ray activity suggesting that some of the young, massive stars have already died in supernova explosions. Six possible neutron stars in the Carina Nebula support the hypothesis that supernova activity is increasing. The nebula also contains Eta Carinae, a variable star over 100 times the mass of our Sun.

Body parts as the zodiac signs

Aries: hips (sassy and proud to be)
Taurus: stomach (always “hungry” for more)
Gemini: tongue (not emotional one bit, and says what they must)
Cancer: eyes (emotional yet beautiful)
Leo: lips (flirty and in your face)
Virgo: legs (gets to where they want to be)
Libra: feet (does amazing things for others)
Scorpio: arm (Strength)
Sagittarius: ears ( good listeners)
Capricorn: back ( they are strong rocks, they just don’t know it yet)
Aquarius: brain (philosophers)
Pisces: heart (follows their emotions instead of facts)

NGC 3576
It’s a humble little cloud located in our galaxy’s Sagittarius arm, and shares the Carina constellation with the bipolar star system Eta Carinae, approximately seventy-five hundred light-years from our planet. NGC 3576 has also been called the Statue of Liberty Nebula, because of an evocative shape near its center.

[ Abstract ]
We have analyzed the double-lined eclipsing binary system ASAS J180057-2333.8 from the All Sky Automated Survey (ASAS) catalogue . We measure absolute physical and orbital parameters for this system based on archival $V$-band and $I$-band ASAS photometry, as well as on high-resolution spectroscopic data obtained with ESO 3.6m/HARPS and CORALIE spectrographs. The physical and orbital parameters of the system were derived with an accuracy of about 0.5 - 3%. The system is a very rare configuration of two bright well-detached giants of spectral types K1 and K4 and luminosity class II. The radii of the stars are $R_1$ = 52.12 $\pm$ 1.38 and $R_2$ = 67.63 $\pm$ 1.40 R$_\odot$ and their masses are $M_1$ = 4.914 $\pm$ 0.021 and $M_2$ = 4.875$\pm$ 0.021 M$_\odot$ . The exquisite accuracy of 0.5% obtained for the masses of the components is one of the best mass determinations for giants. We derived a precise distance to the system of 2.14 $\pm$ 0.06 kpc (stat.) $\pm$ 0.05 (syst.) which places the star in the Sagittarius-Carina arm. The Galactic rotational velocity of the star is $\Theta_s=258 \pm 26$ km s$^{-1}$ assuming $\Theta_0=238$ km s$^{-1}$. A comparison with PARSEC isochrones places the system at the early phase of core helium burning with an age of slightly larger than 100 million years. The effect of overshooting on stellar evolutionary tracks was explored using the MESA star code.

Yeppers! . … summer is coming

Infodoc: A Travel Guide to System 42!

Are you interested in a vacation to one of the most beautiful planets in the galaxy, one that forms the heartlands of the NEC? Look no further than scenic System 42- one of the jewels of the Orion Line!

Situated on the historic orion line, a major trade route linking the Perseus arm to the Sagittarius arm via the Orion Spur. The Orion Line contains several of the most important planets in the NEC, including the the three homeworld’s whose stars make up the constellation of Orion’s Sword. System 42 is one of these three homeworlds, and has one of the lowest populations of these three. Still, though, System 42 is famous for its amazing topography and natural features!

System 42 is a binary star system, with two bright blue giants in a very tight orbit. The system has two rocky orbitals and two gas giants, but is relatively light in free resources, such as asteroid belts. Most of the matter surrounding these stars has long since been collected into orbitals. As such, the system has relatively few industry-based space stations; those that exist are mainly defensive or academic institutions. 

A closer look at the larger of the two blue giants. This star outputs a huge amount of solar radiation each year!

Orbital Ori 3 is a protected planet- the only structures on it are human research stations. This is because Ori 3 is a life-supporting planet: Ori 3 was discovered with simple prokaryotes: simple single-cellular life forms. These life forms flourish the methane-flushed atmosphere of the planet. Because of these life forms, human involvement of the planet is tightly regulated, so scientists can attempt to study how life came about on planets other than earth. This is one of only 11 planets in the Galaxy that have yet been identified to contain life forms!

Most of the rocky orbitals surrounding these two stars are uninhabited, either because of the strong solar radiation or because they are too far out. However, one gas giant, Ori 2, sits at a goldilocks zone in the system, where the solar radiation heats up the planets such that they can be adapted for human life easily! Most of the important planets of the system orbit this beautiful moon, nicknamed the blue marble of the NEC. The planet contains several ‘cloud cities’ harvesting Helium-3, to fuel fission nuclear reactors; however, this industry is tightly regulated, to avoid disturbing the natural beauty of the planet.

 Hyreius is the main inhabited planet of this system. Originally discovered by Canadian Explorers during Phase 2 of colonization, Hyreius was named after one of the figures in the original greek myth of Orion. The planet supported natural liquid water in large quantities, leading it to be the first extraterrestrial planet dubbed an ‘Oceanic Planetoid’. The planet took extremely well to terraforming efforts, which used a combination of bio-engineered bacteria/flora and nanotechnology to convert large amounts of the carbon dioxide in the atmosphere into oxygen. While not especially impressive regarding mineral resources, the planet is able to support a very large population, and at the time far surpassed the population potential of any other system. As such, a large colonial settling recruitment drive was organized for the settlement, mainly from the three main member nations of the NEC, West Africa, Canada, and Indonesia. The planet in a multi-cultural hub of the NEC, representing a pinnacle of the NECs ability to coordinate settlement within it’s member states. 

Hyreius contains one major continent roughly the size of Africa, and many small island chains. The planet has high volcanism, and thus many of these island chains are volcanic in nature. The main continent is united into one direct NEC State, while smaller individual islands were assigned to cultural groups who petitioned for enclaves, government groups such as universities or military outposts, and industrial interests. Additional ‘floating island’ habitats have also been constructed, to take advantage of the vast shallow seas that cover most of the planet. The population of the planet is now in excess of 800 milion residents, making it one of the most highly populated individual planets of the NEC, and it is fully self-sufficient in terms of food supply, though industrial good and building materials are still imported.
