Hubble Spies a Spiral Galaxy Edge-on
NASA – The NASA/ESA Hubble Space Telescope has spotted the “UFO Galaxy.” NGC 2683 is a spiral galaxy seen almost edge-on, giving it the shape of a classic science fiction spaceship. This is why the astronomers at the Astronaut Memorial Planetarium and Observatory, Cocoa, Fla., gave it this attention-grabbing nickname.
While a bird’s eye view lets us see the detailed structure of a galaxy (such as this Hubble image of a barred spiral), a side-on view has its own perks. In particular, it gives astronomers a great opportunity to see the delicate dusty lanes of the spiral arms silhouetted against the golden haze of the galaxy’s core. In addition, brilliant clusters of young blue stars shine scattered throughout the disc, mapping the galaxy’s star-forming regions.
Perhaps surprisingly, side-on views of galaxies like this one do not prevent astronomers from deducing their structures. Studies of the properties of the light coming from NGC 2683 suggest that this is a barred spiral galaxy, even though the angle we see it at does not let us see this directly.
This image is produced from two adjacent fields observed in visible and infrared light by Hubble’s Advanced Camera for Surveys. A narrow strip which appears slightly blurred and crosses most the image horizontally is a result of a gap between Hubble’s detectors. This strip has been patched using images from observations of the galaxy made by ground-based telescopes, which show significantly less detail. The field of view is approximately 6.5 by 3.3 arcminutes. Image Credit: ESA/Hubble & NASA

By David Lazarus – One of the most striking take-aways from this week’s U.S. Supreme Court hearings on the healthcare reform law was the steadfast insistence on the part of Republicans to deny affordable and accessible medical treatment to as many people as possible.
The party is determined to maintain the status quo of healthcare being a privilege and not a right — putting us at odds with just about every other developed nation on the planet and, not coincidentally, resulting in about 50 million people being uninsured.
As I wrote earlier this month, Republican attacks on the mandate as a threat to freedom and liberty ignore the real-world realities of the insurance business. more> http://is.gd/MWffy1

) said Monday (Mar 26, 2012).
“The cost of health care continues to grow because the costs cannot be constrained within the context of that for-profit system,” Kucinich said in a statement after the high court completed the first of three days of oral arguments on the law. “Whether the Supreme Court upholds the law or strikes it down, single-payer is the only alternative that can meet our nation’s needs.” more> http://is.gd/jEQ8AS
