GALAXY THAT SHOULD NOT EXIST - Astronomers have spotted the earliest known spiral galaxy, dating to just three billion years after the Big Bang. Theories of galaxy formation held that the Universe was still too chaotic a place to allow such a perfectly formed or "grand-design" spiral to form. It should take far longer for gravity to bring matter into thin, neat discs. But a team reporting in Nature says the galaxy BX442 got the gravitational "kick" it needed to form a spiral from a smaller "dwarf galaxy" orbiting it. 
They first spotted BX442 as the one and only spiral-looking object in a survey of 300 galaxies carried out by the Hubble space telescope, when they were shocked to see what looked to be a spiral galaxy. 
"What we've learned when we look at galaxies at that epoch is that they're very dynamically hot," explained lead author of the study David Law from the University of Toronto's Dunlap Institute for Astronomy and Astrophysics.

"Even though we see some discs existing at that time, they're very thick and puffy, whereas the Milky Way has an... amount of random motion only about a tenth or so the amount of ordered rotation, giving rise to a very thin disc," he told BBC News. 
Those observations confirmed a hint apparent in the Hubble data: that BX442 was being orbited by a smaller "dwarf galaxy" at its edges. 
"You can get a little extra help if you've got a satellite galaxy orbiting around," explained Dr Law. 
"It gives that extra little gravitational kick to help accentuate the strength of the arm and make it into one of those eye-popping examples like the Whirlpool galaxy that you see all the pictures of." Having proved that such grand-design spiral galaxies can exist at such an early period of the Universe, Dr Law said the team would now like to look into larger, wider-ranging galaxy surveys such as the Hubble telescope's ongoing Candels survey.

Astronomers using the Hubble Space Telescope have discovered the oldest known spiral galaxy that surprised scientists. The galaxy was present in the early universe, about 3 billion years after the Big Bang, at a time when galaxies were still forming and normally looked clumpy and irregular, however this ancient spiral galaxy looks so neat and tidy that “it shouldn’t even exist”. The day that scientists accept that the universe was planned by a Higher mind, they will not be longer surprised to find galaxies "as symmetrical" like this.

In Gita (9-10), the Supreme Lord informs Arjuna that the material nature is always subordinate to Him and is one of His multifarious energies. But at the same time under His direction material nature is able to produce the living and non living entities. The Lord is in the form of purified goodness, being transcendental and has no direct connection with material nature. Maha-Vishnu lying the Causal Ocean from far away casts a glance on material nature by which the material nature becomes agitated to produce this world of living and non-living things. Thus the mere glance of the Supreme Lord is sufficient to create this universe. The primary cause of this creation is the Supreme Lord Krishna while the secondary cause is the material nature. ... In this way, Sri Krishna in the form of Maha-Vishnu is the main reason for creation of the universe and His implements of creation namely, time and His energies are the secondary causes.
