This gaint star Zeta Ophiuchi, a relatively young, located about 370 light-years away, makes waves in the surrounding dust clouds of space, according to NASA experts. Zeta Ophiuchi is about twenty times massive, eight times hotter, and thousands of times brighter than the Sun and travels at a speed of 55,000 miles/hour. This infrared image captured by NASA's Spitzer Space Telescope reveals 'shocking' bow effect produced by this fast moving hot blue star on the surrounding dust clouds seen here as red bow.

The ISS and the Spacetalk
November has been the month of space exploration and it was on November 20, 1998 that a first module 'Zarya' was launched into the space and the works began on the assembly of International Space Station (ISS) at an orbital altitude of 350 km; the final assembly of which was only completed last year. The Space Station now enters the fifteenth year of its existence and therefore, it is only appropriate to mark the
occasion and comment on what is one of the largest and most complex international projects in the history of mankind. As an outsider looking into the Space and while sifting through the volumes of available information, I was profoundly struck by the enormous progress that has been made in space exploration by the human being and all credit goes to NASA and the Project Team of ISS, which comprises of 16 nations including USA, Russia, Japan, 11 European nations, Canada, and Brazil. Surely, many more surprises are in store as NASA nurtures its ambitious plans to move away from the lower Earth orbit (LEO, an orbit below an altitude of 2000 kms or 1200 miles from Earth) to deep space exploration: Moon, Mars, and beyond!
Of late, the project has been mired in a controversy and attracted much criticism from both scientific and political circles alike on the grounds of delays in completion, budgetary overruns, access to the space station and optimal laboratory facilities. This may be untrue because much of the initial phase of ISS has been relegated to the assembly and the research on biomedical, materials science, and the development of space technology for obvious reasons as maintaining the safety, health, and optimum performance of the astronauts and or the space station is of paramount importance and that the human presence in space is vital to any mission success. The achievements cannot be understated as more than 200 research publications have resulted from the direct offshoot of the experiments conducted under microgravity conditions aboard ISS.

Isn't it high time that the Nobel Committee take a serious look at the unprecedented cooperation between the nations cross continents and the tremendous progress achieved by the multinational Team ISS and award its coveted Peace Prize to the mission. I am sure such a move would send positive signals across the international community and open up new avenues for the exchange of cooperation on a similar scale between the nations not only in the softer areas of science and technology but also harder aspects of missile defense and guided technologies and in reducing the arsenals of mass destruction thus directly furthering the cause of global peace.

Big Bang Revisited!
This computer animation, created using new software called Arepo, simulates nine billion years of cosmic history. Created by a team at the Harvard-Smithsonian Centre for Astrophysics (CfA) in collaboration with researchers at the Heidelberg Institute for Theoretical Studies (HITS), Arepo can accurately follow the birth and evolution of thousands of galaxies over billions of years.

Open Access Explained!
Here's an interesting video on open access journals. It is hilarious and raises some interesting questions on this practice of journals drawing rather expensive research material at no cost from the authors while charging exorbitant subscription fees. The original video is from http://www.phdcomics.com/comics/archive.php? comicid=153. Have a look and draw your own conclusions.

On Writing Styles
I find this interesting vimeo of an interview with Steven Pinker on writing, wherein he talks about where to begin, style, and the importance of knowing your audience; very informative, analytical, and helpful for all those upcoming writers out there. Steven is Harvard College Professor and Johnstone Family Professor in the Department of Psychology at Harvard University and this vimeo is from: http://www.cambridgenights.com. Here's another Link to his hour-long lecture given at MIT on "Communicating Science and Technology in the 21st Century". Take a look!

Hurricane Sandy Batters U.S. East Coast
Hurricane Sandy slams densely populated East Coast of the United States virtually disrupting the life of nearly 75 million people in its path from North Carolina to New England. Total shut down is reported in almost eight states including New York, New Jersey, Pennsylvania, Connecticut, Massachusetts, Delaware, Maryland and Virginia. Millions of people are without power. Atlantic City, New Jersey is the hardest hit as most of the city inundated with 3-5 ft flood water per latest reports. New York City, the city that never sleeps, is completely shut down as nearly 8 million New Yorkers have been ordered to stay home and do nothing. No local and international flights are going in and out of the city and so do train or bus services. President Barak Obama cut short his scheduled presidential campaign and returns to White House to oversee the emergency operations. President later signs the emergency disaster declaration for the eight affected states. Wall street will be shut down for Monday and Tuesday as the financial losses due to hurricane Sandy is estimated at $17.2b with most of the losses are expected from damages due to flooding and storm water inundation of the cities and boroughs across the coastline.

Endeavour's Final Journey
WOW! Here's an amazingly shot video, The Final Journey of Space Shuttle Endeavour from Los Angeles International Airport (LAX) to the California Science Center through the streets and alleyways of the City of Angels. Dubbed as Mission 26: The Big Endeavour, the space shuttle completed 123 million miles in space since it entered into service twenty years ago. The 75-tonne space shuttle was transported on a 160-wheel carrier traveling at a speed of 2 mph, took two days to cover the 12 miles from LAX to its final resting place as the people swarmed the city to witness the historic moment. Take a look!
