Astrophysicist Mayank Vahia and his colleagues at the Tata Institute of Fundamental Research mentioned in the study that the rock art could be the oldest record of a supernova. The theory of sun and moon has been negated though on account of the proximity of two objects on the markings, and also because of the fact that moon should appear less bright when it is nearer to the sun. They found that supernova HB9 had exploded around 3600 BC making it highly pobable that the markings indeed show evidence of the same supernova.
The rock art, which shows figures of humans and animals below a sky where two objects seem to be shining brightly, is said to date back to between 2100 and 4100 BC. We search the supernova catalogue to look for a possible supernova that could have had the brightness comparable to that of Sun or Moon and close to ecliptic between 2000 BC and 10,000 BC since the etching is believed to have been done prior to 2000 BC and be visible from Burzahama.
A supernova is a massive stellar explosion that takes place during the death of certain stars.
President Trump mocked for possibly not knowing the National Anthem
This is not the first time people have raised dementia concerns when it comes to the United States president. Mr Trump has had a controversial relationship with the national anthem during his term in office.
"This is not a terrestrial hunting scene but is actually a sky-map giving location of prominent constellations and the Moon on the day the supernova was first observed", he noted.
But astronomers have nearly as much trouble figuring out when a supernova exploded as archaeologists do pinpointing when a carving was made.
The oldest human art is substantially earlier than normally assumed and carved humanfemale forms have been dated to seventy five thousand years or more. The oldest settlement in Burzahama was found to have a history dating back to around 4100 BC.
AAP candidates Sanjay, 2 others elected unopposed to RS
The Opposition parties did not nominate any candidate for the seat as AAP enjoys a brute majority in the 70-member Delhi Assembly. Maken also alleged that Gupta held the office of the chairman of the Audit Committee of the National Pension System Trust.
Apparently, Vahia and his colleagues guessed it to be a supernova and along with sun in the unusual picture where few people are hunting down a dear-like animal under two bright objects.
The carving also consists of a figurine resembling an animal to the left of the hunter drawn above the hunter's spear suggesting that the depiction could be a hunting scene.
Sony A8F OLED and X900F 4K HDR TVs pack X1 Extreme processor
The display uses Sony's TRILUMINOS tech and X1 Extreme processor, along with support for HDR10 and Dolby Vision playback. Pricing and availability for Sony's new A8F Series and X900F Series 4K Ultra HD TVs have not been announced yet.
"We, therefore, investigate the possibility that the rock drawing is the record of the supernova HB9".
