Reality Crowd

I enjoy this discovery because it reminds me of a concept I learned while studying music. Playing very high notes or very low notes (especially on wind instruments) is difficult. Players spend years trying to stretch that one half-step further or gain the ability to play just a little louder or keep control at the very softest tone. Stretching your ability that far, though, has more value than just being able to finally hit that high C. The benefit also lies in the fact that all the notes you play in between—the notes you have played for years—become stronger as you expand your total range.

This gamma ray burst is like that high C, and understanding it will bring the benefit of better understanding all the galaxies, stars, and other celestial objects in between that we have been “playing” for years. Our understanding of physics will become more refined as scientists may now have a glimpse into the very first generation of stars (with undoubtedly different properties from stars we commonly study today). For a more detailed description of this event and its implications, view the NewScience article here.

Please comment what this discovery means to you (even if you don’t see why a little yellow smudge could get people so excited)!


Timelapse: Nightscapes from Tom Lowe on Vimeo.

Sometimes our view of the world around us is held back by our own perceptional limitations. When we use technology to work around those limitations a whole different view of our surroundings is opened to us. Check out these timelapse shots of the night sky. Amazing.

University of Sydney scientists have discovered that our galaxy, the Milky Way, is twice as wide as previously thought. It seems very strange that this could be the case, doesn’t it? Scientists have peered billions of light years into the cosmos. They have made observations and calculations of mass and distance of a multitude of celestial objects and even of the universe itself. But right here at home, our own galaxy we calculated to be about 6,000 light-years thick, and these scientists now claim that in reality, it is 12,000 light-years thick. It is fascinating to learn that these scientists did not even make any new observations; they simply used data already collected that was available on the Internet! This surprising result has elicited mixed emotions from the scientific community. From the University of Sidney article:

“Some colleagues have come up to me and have said ‘That wrecks everything!’” says Professor Gaensler. “And others have said ‘Ah! Now everything fits together!’”

Here at RealityCrowd, we often cite ways in which science and religion are opposed. This event is a beautiful example of how in the scientific community, new evidence can change even a long-held belief. If assertions are supported by evidence, then those assertions must be taken seriously. However, religion, as many readers realize, does not change in the light of new evidence, and this is why we incessantly hear unsupported claims from many Christians such as the age of the universe being only about 6,000 years. Not even the mountain of evidence to the contrary will convince a true Bible believer. This unwavering stance may be comfortable for those who need the universe to be predictable and simple, but those of us with open and inquisitive minds will celebrate these times that we can say, “Hey, we were wrong!”

Science Educator Roy Gould and Curtis Wong from Microsoft give an amazing preview of the Worldwide Telescope. Think of it as a Google Maps for the entire Universe. Set to debut this spring, the worldwide telescope will take images from many different telescopes and stitch them into one comprehensive view of the universe. This is a revolutionary idea, for the first time normal everyday people will get to see what until now only astronomers and astronauts have had access to. What’s the cost for all this amazingness? Nothing!

Update - Here is another great video from fastcompany.tv

Here are some highlights from the www.worldwidetelescope.org frequently asked questions page (FAQ):

Q. What is WorldWide Telescope?
A. The WorldWide Telescope (WWT) is a rich visualization environment that functions as a virtual telescope, bringing together imagery from the best ground- and space telescopes to enable seamless, guided explorations of the universe. WorldWide Telescope, created with Microsoft®’s high-performance Visual Experience Engine™, enables seamless panning and zooming across the night sky blending terabytes of images, data, and stories from multiple sources over the Internet into a media-rich, immersive experience.

Q. What are some of the most compelling features of WWT?
A. WorldWide Telescope is an observatory on your desktop, allowing you to see the sky in a way you have never seen before; individual exploration, multi-wavelength views, stars and planets within context to each other, zoom in/out, and a capability for anyone to create and share a tour of the universe.

The Visual Experience Engine delivers seamless panning zooming around the night sky.

WWT delivers seamless integration of science:-relevant information including multi-wavelength, multiple telescope distributed image and data sets, and one-click contextual access to distributed Web information and data sources.
