AstroSat Picture of the Month (November 2017) NGC 1851: Two star families in one Globular Cluster NGC 1851 is a Globular Cluster which is almost 40000 light years away from us, in the southern constellation of Columba, near Canis Major. A Globular Cluster is a group of hundreds of thousands of stars tightly bound together by their own gravity. All the stars in these spherical clusters orbit around the centre of our galaxy together. NGC 1851, or Caldwell 73, is one such cluster, visible in a moderate telescope at a magnitude of 7.3, with a size that is a third of the full moon. It was discovered by James Dunlop from Australia in 1826. The stars in a Globular Cluster are usually born together, and hence share similar properties. However, NGC 1851 is one of the few clusters where two distinct types of stars with different properties seem to co-exist! Many individual stars in this object have been studied before with the Hubble Space Telescope (HST), but good ultraviolet images were needed to understand this mystery better. This prompted a group of 18 astronomers, including 12 from India, to use the UVIT on board the AstroSat. They imaged this cluster in the Near and Far ultraviolet wavebands far better than earlier attempts with other telescopes. The superior resolution of AstroSat allowed them, for the first time, to measure the ultraviolet properties of individual stars in the inner crowded region of the cluster. Using this data, they could show that NGC 1851 does indeed have two distinct families of stars within it, which still retain their separate histories. This tells us that NGC 1851 was probably formed when two smaller clusters merged together some time in the past! pic Near-UV (left) and Far-UV (right) images of the Globular Cluster NGC 1851, taken by UVIT onboard AstroSat. The FUV image shows only the hottest stars in the cluster. All colours are artificial. 1 Like

In 1973 there was an offer from Germany to jointly develop the HF 24 into the Hindustan Supersonic Strike Aircraft labelled the HSS 73 later to be known as the HF-73. This would retain the original mainframe, with radical changes to the fuselage, air intakes and the centre wing section. The cockpit was to be modified for better visibility, fuel capacity increased, and with a completely new avionics suite and powered by the Rolls Royce RB 199-34R engine would have a radius of action double that of the HF 24. “Eventually, this project had to be abandoned because, as some said, of non clearance of the RB 199 by the UK and Germany, the two partner governments involved in the engine development for the Tornado MRCA programme. Thus all efforts in developing an Indian combat aircraft had come to naught.”

nemesis4u: very stupid comment,as they only calcalulate the cost and income of a singe port, but not calculate the impact of that port , the overall change to the local economic growth and development. China pay most of the investment of the China-Pakistan Economic Corridor (CPEC) .and this will change the geopolicial map of this region as many chinese import and export commodity will no longer through the Malacca Strait。 it's the same thing Greece sell Piraeus port and gain economic development and boosts employment. http://www.bbc.com/news/world-asia-china-27960661 https://thediplomat.com/2016/04/how-a-greek-port-became-a-chinese-dragon-head/ Then why do you think Greece and Serbia invited China to make Balkan canal of course the old EU will not be happy ,the project is suspended now the Hungary-Serbia railway https://euobserver.com/eu-china/140068 1 Like
