Previous episodes can be found here. So with all that said, let's step in to the carnival and enjoy the show!
The first blog we come to is the always well written blog UniverseToday with senior editor, Nancy Atkinson submitting. This week Nancy shares the before and after shots of the terrible earthquake and Tsunami that rocked Japan last week. The post can be found Here.
(as a side note) I personally wish the people of Japan a speedy and safe recovery from the collection of calamities that have struck this country.
Next in our quest for all things space we have Allen Versfeld and his Blog: Urban Astronomer. Here, Allen discusses how New observations made by the Hubble Space Telescope have refined our measurements of the expansion of the universe. These new figures strengthen the case for Dark Energy by eliminating a competing theory. Sounds like a team of scientists just got sacked! ouch that always stings when it is your research. I feel their pain. I just knew the Ether was a sure thing...
On to our next big thing and that is Next Big Future. Brian Wang, the thinking man's Thinking Man sorts out, In space it is relatively easy to move quite large space rocks using solar sails, ion drives and other means. There are a lot of space rocks and a survey could be done to select the rocks that would have to be moved with the least amount of effort. Then once each asteroid is moved into place they would be locked into place. It could be easier to gather asteroids to make desired shapes instead of digging out a larger asteroid. Different sized asteroids could be used from 500 kg, to tons up to asteroids that are 100 to 1000 meter across. Brian is amazing! I would love to hang out with him but I am afraid my head would explode. His thought provoking article can be found Here
On to Ian Musgrave of Astroblogger fame Ian tackles the Super Moon issue. Is it the bringer of death and carnage or is it just another full moon that just so happens to be at Perigee? Ian sheds some light on this well written piece. Yes, I slipped a pun in there... Go Here for all things Super Moon.
Vega 0.0 Fran Sevilla of Vega 0.0 delivers big with an Introduction to the comoving coordinates in cosmology. This is number 16 in a series so you might have some catching up to do there but as always a fascinating read. This Blog is in Spanish but have no worries if you scroll down on the right side you will find the Google translator application. translate it to the language of your choice and enjoy getting your head around our ever expanding universe. Check this blog out... Here
Steve Nerlich over at Cheap Astronomy has a treat for your ears and mind. Steve delves into the unravel the whole density wave spiral arm story. Take a listen and then think about that! Pick up what Steve is putting down right Here . I really don't have a logo to post for Steve because he is frugal or I would!
How can our universe (or the one we are in at the moment) exist at the same time as another one? Would the other universe be a mirror image of this universe or would it have the same stuff in it but the stuff act differently from what we are experiencing now? Those are some very good questions and for the answers or some answers. Go to the venerable Sage of Warp Chris Dann and his Blog Weird Warp for the skinny.

This week They've been showcasing a series of videos about the Universe made by astronomers in Portsmouth. Three have been posted here with two more to be seen at this site.

Lastly, I offer for your enjoyment the witty repartee of Steve's Astrocorner as he takes a look at the Sun with a filter of course and ponders the latest study going about solar cycles. You can look at the Sun talk Here
I knew if I was ever going to get "witty repartee" and my blog in the same sentence I was going to have to do it my self . With That my friends is the end of Carnival 189 I hope you enjoyed it. As I leave you. I just wanted to say happy birthday to the Cincinnati Astronomical Society as they celebrate 100 years of astronomical excellence.
Until next time,
Keep looking up!
