Downtown Milkyway – Image of the day March 28 2011

There’s a party in our galaxy’s “city center,” and thousands of stars have gathered to light up the scene.

In visible light this region of the Milky Way is so bright that it’s almost impossible to see what’s happening. But new infrared pictures from NASA’s Spitzer Space Telescope—such as the one above released March 18—can reveal the raucous activity.

In the new shot, tendrils of warm gas (yellow-red) and carbon-rich dust (green) drape across the galactic center, where bright white star clusters are orbiting an unseen supermassive black hole.

First Visible-Light Snapshot Of A Planet Circling Another Star


Artist’s concept of the star Fomalhaut and the Jupiter-type planet that the Hubble Space Telescope observed. A ring of debris appears to surround Fomalhaut as well.

Estimated to be no more than three times Jupiter’s mass, the planet, called Fomalhaut b, orbits the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis, or the “Southern Fish.”

actual-imageThis visible-light image from the Hubble shows the newly discovered planet, Fomalhaut b, orbiting its parent star.

The planet is brighter than expected for an object of three Jupiter masses. One possibility is that it has a Saturn-like ring of ice and dust reflecting starlight. The ring might eventually coalesce to form moons. The ring’s estimated size is comparable to the region around Jupiter and its four largest orbiting satellites.





Future observations will attempt to see the planet in infrared light and will look for evidence of water vapor clouds in the atmosphere. This would yield clues to the evolution of a comparatively newborn 100-million-year-old planet. Astrometric measurements of the planet’s orbit will provide enough precision to yield an accurate mass.

Big Bang – A 2000 year old theory?

While scientists around the globe were busy with the LHC experiment, i was doing my own research on the “Puranas”. Thought to have been written 2000 years ago, they are the religious texts which talk about the creation of the universe (and much more).

One thing in particular grabbed my attention 

In the beginning the Brahm pervaded the entire universe. When it was time for creation, the Brahm manifested itself as the three supreme gods, BrahmaVishnu and Shiva.” Then water was created and out of the water arose a huge many-headed serpent known as Seshnag. Vishnu took this serpent as his resting place. Next from the waters came a golden egg shining with the brilliance of a thousand suns. Brahma, the Creator, entered the egg and for a thousand years carried on the work of creation within the egg.  After a thousand years the egg hatched into two parts. The upper part was made the heaven and the lower part the earth. The sun emerged from the egg and took its ordained place in the heaven. Since it was the first to emerge it is known as Aditya. The various landforms, rivers, oceans and mountains then followed.”

It is interesting to note that now we know that during the big bang there were 4 fundamental forces at work (electromagnetism, weak nuclear force, strong nuclear force and gravitation) . Could this be Brahm, Brahmma, Vishnu and Shiva?  

Also could the “golden egg shining with the brilliance of a thousand suns” be the universe at initial stage? 

The Vedas never talk about any explosion but simply say that Brahma entered the egg and for thousand years carried on the work of creation of egg. Interestingly scientists say that ” there was no explosion; there was (and continues to be) an expansion. Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe. “(Source: Big Bang Theory website).

Were our ancestors explaining the Big Bang theory 2000 years ago?
