Community Policy (Read this)  - 
 
Please read the community policy and guidelines before posting.  

First read this few, important words by our fellow moderator +Jason Major :

"Just a quick note (PLEASE READ) – if you post an article here that has already been shared recently, especially multiple times, OR if you post an image or video (even space-related) with no content, description, or attribution, it will be removed.

Thank You - Management"

Please refer to the Community Policy at left for more information. Thank you.
 
It's About Respect 
 
One of the things we do a lot as moderators of the Space community is remind posters to give proper attribution and link-backs to the authors and artists whose work they're sharing with everybody. Though the rules are pretty simple - put the name of the content creator in your post, if the work is copyrighted put the name of the organization that owns the copyright (if different from the author) in your post, and include a link back to the original source - they're often not heeded. The moderating team understands that even these simple rules are significantly stricter  than what people find in most of social media, and so we try to give people ample warning and reminders of the expectations here. 
 
If we know the rules surrounding sharing are stricter than in other communities, why do we have them?  If the copyright boogymen aren't coming for you on Facebook, Pinterest, Tumblr, or even elsewhere on Google+, isn't it safe to just share freely with the Space community? 
 
Well, simply put, yes. Unless you're posting something that's explicitly and blatantly illegal, the legal ramifications of your sharing a quote, or an image, or what have you are nil. Nobody's coming to get you. 
 
But that's not the point. It's not about the law. We're not trying to cover our behinds, and we're not reminding you to cover yours. In fact, many of the images we're all sharing are in the public domain, and are not protected by copyright laws. 
 
It's about respect. 
 
By naming the scientist, author, artist, photographer, videographer, director, producer, or whoever it is that has created this work that you feel is worth sharing in your post and including a link back to the original source, you are showing your respect. You are showing your respect to the creator of that work, and, perhaps more importantly, you are showing your respect to the other members of this community. 
 
As moderators, we want to build a community that is built on respect, and one of the most significant ways we can show respect is to give credit where credit is due. We want to foster an attitude around content sharing that is respectful, that is not exploitative of artists and authors, and that does not take the members of this community for granted. 
 
As a denizen and frequent user of social media, you may not care about giving credit, and as a content creator yourself, you may not care if you get credit. In the end, however, it isn't about you, nor is it about what you care about. It's about this community as a whole, and what kind of community we all want it to be. What we want is a community that does care. 
 
We want a community that cares about attribution because it's curious about where things come from, and because it's respectful toward others.

Star Formation in the Tadpole Nebula 
Image Credit: WISE, IRSA, NASA; Processing & Copyright : Francesco Antonucci

Explanation: Dusty emission in the Tadpole nebula, IC 410, lies about 12,000 light-years away in the northern constellation Auriga. The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. Formed in the interstellar cloud a mere 4 million years ago, bright cluster stars are seen all around the star-forming nebula. Notable near the image center are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation in IC 410, these cosmic tadpole shapes are about 10 light-years long. The featured image was taken ininfrared light by NASA's Wide Field Infrared Survey Explorer (WISE) satellite.

There are forty-nine new papers listed in Astro-archives today. These topics caught my eye: *Gravitational waves, LOFAR, TeV flares,
Modified Maxwell Equations*

Gravitational Waves from Neutron Stars: A Review http://arxiv.org/abs/1508.06643 This review covers the expectations of the Advanced LIGO's first science run started August 17 . LIGO runs to date have been used to rule-out compact binary coalescences as sources of local gamma ray bursts because no gravitational waves have been detected. If the current generation of LIGO antenna/telescopes do not identify many coalescent events, it is time to revisit the fundamental theory. https://ligo.caltech.edu/

Galactic interstellar filaments as probed by LOFAR and Planck http://arxiv.org/abs/1508.06652 The magnetic fields of interstellar space are pathetically weak, so it is quite unexpected to find a column of dust closely aligned with a magnetic filament: But there it is; in living radio waves. Perhaps the 'magnetic dust' is not what we think it is.

VERITAS observations of exceptionally bright TeV flares from LS I +61$^\circ$ 303 http://arxiv.org/abs/1508.06800 Now that Advanced LIGO is up-and-running; it would be nice to have another toenail flare-up like this one: Good constraint on gravitational waves, if not an out-right detection.

Electrodynamics on Cosmological Scales http://arxiv.org/abs/1508.06910 The universe is a tough place for Maxwell, his field equations work well at your local radio station, but run into vanishing limits on cosmic scales. With a need for cosmic acceleration; there are also reasons to define matter at the fields associated with it in ways the are consistent with dark energy science. (If this paragraph sounds like so much smoke and mirrors, you have broken the code.)

This budget line has saved thousands of lives so far, and maybe many more than that in the near future, as climate change accelerates. However, the infrastructure is getting old and the budget is still very limited. All started with the Tiros series back in the early 1960's.

Using results from the Herschel Astrophysical Terrahertz Large-Area Survey (H-ATLAS) and the Galaxy and Mass Assembly (GAMA) project, we show that, for galaxy masses above ≃ 108 M⊙, 51 per cent of the stellar mass-density in the local Universe is in early-type galaxies (ETGs; Sérsic n > 2.5) while 89 per cent of the rate of production of stellar mass-density is occurring in late-type galaxies (LTGs; Sérsic n < 2.5). From this zero-redshift benchmark, we have used a calorimetric technique to quantify the importance of the morphological transformation of galaxies over the history of the Universe. The extragalactic background radiation contains all the energy generated by nuclear fusion in stars since the big bang. By resolving this background radiation into individual galaxies using the deepest far-infrared survey with the Herschel Space Observatory and a deep near-infrared/optical survey with the Hubble Space Telescope (HST), and using measurements of the Sérsic index of these galaxies derived from the HST images, we estimate that ≃83 per cent of the stellar mass-density formed over the history of the Universe occurred in LTGs. The difference between this value and the fraction of the stellar mass-density that is in LTGs today implies there must have been a major transformation of LTGs into ETGs after the formation of most of the stars.

+Gert Sønderby - Thank You for commenting...I was unaware of that fact.  Here is what I also identified while researching the Refurbished Russian Engines.
-  Early in October, Aerojet said it was in the running to provide a replacement engine for Russian-made RD-180 launch motors for the Atlas V rocket program. The RD-180 is a modern Russian rocket, and not a refurbished surplus engine. Many American military space launches currently depend on RD-180 first-stage engines, which produce 1 million pounds of thrust. Future access to those engines is in doubt, however, with the current conflicts between Russia and the U.S. over Ukraine. Also, the U.S. Air Force is seeking a domestically built rocket. Aerojet is in the bidding to build that motor. Another bidder is the aerospace company ATK. http://www.bizjournals.com/sacramento/news/2014/11/05/orbital-sciences-aerojet-refurbished-rocket.html

  #GJ436b  The Frozen Fireball Exoplanet

This is an artists depiction of a bizarre comet-like exoplanet named Gliese 436b, or GJ 436b for short.

It is located about 33 light years from Earth in the Constellation Leo, and has several awesomely unique features. This planet is called a "warm Neptune," because while having about the same mass as Neptune, it is located closer to its star than Mercury is to the Sun.

Using the Hubble Space Telescope, Astronomers detected an enormous gas tail following the planet around its orbit. Scientists predict that a tail of this size would require the planet to blow off an astonishing 1,000 tons of gas per second, which is a measly 0.1 percent of the planets atmosphere every billion years or so.

The most interesting feature of this planet however, is that the planet harbors "ice" that exceeds temperatures of 400 degrees Celsius. This is possible because the gravity of the planet is so strong that upon melting, water vapor cannot escape, and remains in a solid form.

Basically, this planet is a frozen fireball.

A group of researchers from Ehime University, Princeton University, and the National Astronomical Observatory of Japan (NAOJ) among others has performed an extensive search for Dust Obscured Galaxies (DOGs) using data obtained from the Subaru Strategic Program with Hyper Suprime-Cam (HSC). HSC is a new wide-field camera mounted at the prime focus of the Subaru Telescope and is an ideal instrument for searching for this rare and important class of galaxy. The research group discovered 48 DOGs, and has measured how common they are. Since DOGs are thought to harbour a rapidly growing black hole in their centres, these results give us clues for understanding the evolution of galaxies and super-massive black holes.

+Brett Stevens and this engine uses Kerosine instread of H2. no pressure. requirement.

BUT H2 and Oxygen offer the pressure required to achieve the fuel flow required to generate the thrust required.

The russian Engines do this at super high pressure, 30kpsi at high temperature.
