The Super Moon 2013!

Everyone, today on Sunday 23rd of june 2013, its the super moon. The moon today would be the biggest and the brightest moon of this year. Stargazers and astronomers will get a rare chance to observe the year's largest fullmoon. 

The moon will be at its closest distance(the Perigee) to Earth in its orbit, a distance of 356,991 km(221,823 miles). Astronomers believe that the supermoon can cause natural disasters. This Sunday's full moon will have an effect on high and low ocean tides.    

 In India, people can watch the supermoon all night after 6.40 pm on Sunday. But the best time to view the full moon is between 4.30 am to 5.30 am (7 am EDT) on Monday when it is very close to the horizon.

One can follow their website on Slooh.com or also watch the live stream that will start on 23 June at 6 pm EDT and 9 pm EDT. Viewers can also download Slooh iPad app from the iTunes store to watch the phenomenon live on their PC, MAC and mobile devices.

The Great Attractor!!!

The Great Attractor is far bigger than a galaxy. In the terminology of astronomers, these are clusters of galaxies containing maybe hundreds of galaxies, and superclusters containing many clusters.
The Norma Cluster is the closest massive galaxy cluster to the Milky Way, and lies about 220 million light-years away. The enormous mass concentrated here, and the consequent gravitational attraction, mean that this region of space is known to astronomers as the Great Attractor, and it dominates our region of the Universe.

Our galaxy, along with other galaxies in our local group, is currently rushing at a speed of nearly 1,000km per second towards the Great Attractor which is about 220 million light years away from us.

This Great Attractor has a mass of nearly 100 quadrillion times greater than our sun and span of 500 million light-years, and is made of both the visible matter and dark matter.
So in a way its a massive black hole which is pulling us.
This motion can only be accounted for by gravitational attraction, even though the mass that we can observe is not nearly great enough to exert that kind of pull. The only thing that could explain the movement of Andromeda is the gravitational pull of a lot of unseen mass--perhaps the equivalent of 10 Milky Way-size galaxies--lying between the two galaxies.

Meanwhile, our entire Local Group is hurtling toward the center of the Virgo cluster at one million miles per hour.
