Railguns

------
Railguns are so incredibly powerful, it's hard to accept these things are real when first exposed to them.


Further development has just been unclassified and reported on the US Navy's new railguns.





You should know that the energy involved in shooting a "normal" gun is of a level fit for its mass.  The lightweight shell of a 50 cal, you're no longer impressive.

We have set the world record for the highest energy projectile,
33 megajoules...
a 23 pound bullet...
5500 feet in a single second.

None of those numbers are typos.

The navy states they have goals for a version capable of 10 projectiles per minute, hopefully accurate to distances of 50-100 nautical miles.

From previous research on railguns, I've read about versions of these projectiles capable of fragmenting and raining down high speed destruction over large square footage.  Compared to a shotgun, we're going from slugs to buck shot.

This weapon is undoubtedly scary.  However, this is unclassified and reported.
What may be classified is what scares me.

Time Lapse Vid / Supernova

------
Two media based science stories today stuck out like sore thumbs:


"Astronomer's Paradise"
Calming astronomical time-lapses accompanied with some chill downtempo music.  

Astronomer's Paradise from Christoph Malin on Vimeo.
Personally, to jive with the title I would have recommended Coolio's "Gangster's Paradise."  I'm almost tempted to correct that and reupload.  Alas, that's potentially offensive in addition to having a copyright issue.






AND:






"Happy 25th annniversary, Supernova 1987A!"
A throwback post of his, stunning nevertheless.

Video: Zooming Into Space

------

From the ESO, European Southern Observatory:
"Zooming in on the star formation region NGC 3324"
"Starting from a broad view of the Milky Way, this zoom video closes in on spectacular region of star formation called NGC 3324 within the constellation of Carina (The Keel of Jason’s ship, Argo)" -ESO

Sorry for the video size, ESO's embedding code doesn't give much wiggle room for modification.

NASA's Aerial Superhighway

Brand Spankin' New out of NASA/Godddard Media

"Aerial Superhighway"


This one, for a change, has a nice little soundtrack behind it.

"Meandering around the planet like a rollicking roller coaster in the sky, the Northern Hemisphere's polar jet stream is a fast-moving belt of westerly winds that traverses the lower layers of the atmosphere." -NASA



So new, it wasn't online, on youtube or other similar sites for streaming.  Public Domain.  I uplaoded to my Youtube and HERE YA GO!  Hope you enjoyed!
