NEPTUNE'S MOONS 'DANCE' TO AVOID HITTING EACH OTHER.

More than 2.7 million miles away, Neptune is the furthest planet from Earth in our Solar System, meaning it's one of the least explored worlds. Now, NASA has revealed new findings about two of Neptune's moons, and how they must 'dance' to avoid smashing into each other. The moons called Nalad and Thalass, orbit just 1,150 miles apart, but have perfectly coordinated orbits. When they pass each other, they are about 2,200 miles apart. In this cosmic dance, Nalad swirls around Neptune every seven hours, while Thallas takes the outside track, and takes 7.5 hours to orbit. Nalad's orbit follows a bizarre zigzag pattern which NASA has never seen before. "We suspect that Nalad was kicked into its tilted orbit by an earlier interaction with one of Neptune's other inner moons. Only later, after its orbital tilt was established, could Nalad settle into this unusual resonance with Thallas", said Marina Brozovic, who led the study.

VIEWS OF MANU AND KAUTILYA ON THE ADMINISTRATION OF JUSTICE.

The state performed its duty of protection of society and the individual through coercive enforcement of the standards of justice based on the concept of ' Dharma '. From the Vedic period onward, the perennial attitude of Indian culture had been justice and righteousness. Justice, in the Indian context, was a human expression of a wider universal principle of nature and if men were entirely true to nature, their actions would be spontaneously just. Men experienced Justice, in the sense of a distributive equity, as moral justice, social justice, and legal justice. Each of these forms of justice was viewed as a particularisation of the general principle of the universe seen as a total organism. Impartial administration of justice was always regarded as one of the main duties of the King and he was considered to be the fountain of justice. The ethical code of society and its cultural standards were inter-related. The cultural maturity and social amicability and even their det...

ARCHAEOLOGISTS DISCOVER TOMBS IN EGYPT DATING BACK 2,000 YEARS.

Egypt's antiquities ministry said on 14th August, 2017 (Tuesday) that archaeologists have discovered three tombs dating more than 2,000 years, from the Ptolemaic Period. The discovery was made in the Nile valley province of Minya south of Cairo, in an area known as al-kamin al-Sahrawi. The unearthed sarcophagi and clay fragments suggest that the area was a large necropolis from sometime between the 27th Dynasty and the Greco-Roman period. ----------------------------------------------------------------

ANCIENT INDIA'S LINKS TO TODAY.

You may not have heard of Shu-ilishu but he is a man of great significance. He reaches out to us from almost 4,300 years ago, through a small Akkadian cylinder seal now housed at the Louvre Museum in Paris. On the seal, you will find an image of him talking to two men. The inscription describes Shu-ilishu as the interpreter of the Meluhhan language. 'Meluha' was, in all probability, the term used by ancient Mesopotamians for the Indus Valley region, and the presence of an oficial 'interpreter' there indicates just how important the steady flow of good from the Indian sub-continent was.  Precious and vibrant lapis lazuli stones, carnelian beads, wood and even dogs would go across via old trade routes and ports like Lothal (in modern-day Gujarat) to Akkad, capital of the Akkadian Empire (03rd millennium BCE) and now in modern-day Iraq. There are also references to a settlement of Meluhhans in the city of Guabba in Sumer, in Mesopotamia.  The story of Shi-ilishu and ...
