Image
                                   ornithoptera alexandrae , the  Queen Alexandra's birdwing , is the largest  butterfly  in the world, with females reaching wingspans slightly in excess of 25 cm (9.8 inches). It is restricted to the forests of the  Oro Province  in eastern  Papua New Guinea . The species was named by  Walter Rothschild  in 1907, in honor of  Alexandra of Denmark . The first European to discover the species was  Albert Stewart Meek  in 1906, a collector employed by Walter Rothschild to collect natural history specimens from New Guinea. There are two type of  ornithoptera alexandrae, male and  female. Female: Female Queen Alexandra's birdwings are larger than males with markedly rounder, broader wings.

THE BLACK JAGUAR AS AN ENDANGERED SPECIES

Image
The term “black panther” may be applied to several types of great cat, but in the   Amazon it refers to jaguars. Not a separate species, but a rare color variant, black jaguars are powerful hunters and play a vital role within their ecosystem. Like all jaguars, these carnivores are masters of ambush, and it is thought that their dark color adaptation might aid these cats in their hunting. Unfortunately, like all jaguars, this color variation of the species is just as susceptible to threats like habitat loss.                                                                           These jaguar are mainly found in the area's   the  equatorial rainforest  of  Malaya  and the  tropical rainforest  on the slopes of some African mountains such as  Mount Ke...

World's smallest satellite 'KalamSat' built by Indian teens launched by NASA

  18-year-old Rifath Sharook of India build smallest satellite :- Although the space shuttle program may have been temporarily halted in the United States,  NASA  is still alive and well — and now, thanks to 18-year-old Rifath Sharook of India, are launching their smallest-ever satellite into space. The satellite is called 'KalamSat,' named after Indian nuclear scientist, pioneer in the aeronautics field, and former president, Dr. APJ Abdul Kalam, and is the first-ever to be manufactured by 3-D printing, a tech trend we don't see disappearing (or even going away a bit) anytime soon. Rifath's satellite beat out of a slew of other inventions at a competition jointly sponsored by NASA and 'I Doodle Learning' called 'Cubes in Space,' in an effort to bring new technologies and devices to space and solve current quandries as well as new ones. "The main role of the satellite will be to demonstrate the performance of 3-D printed carbon fibre. Desp...
