Rafflesia : The largest flower...


The flower in the world with largest bloom is Rafflesia arnoldii.
It is commonly known as Corpse lily.
Rafflesia arnoldii  is one of the three national flowers in Indonesia, the other two being the white jasmine and moon orchid.
The first botanist to find a specimen of a Rafflesia was the French explorer Louis Auguste Deschamps (1765–1842). 
It is a species of flowering plant in the parasitic genus Rafflesia. 
Rafflesia arnoldii is a parasitic plant, without roots or leaves.
The flower of Rafflesia arnoldii grows to a diameter of around one meter (3 ft), but the greatest measurement from a reliable source is 105 centimeters (3.4 ft).
 This plant produces no leaves, stems or roots and does not have chlorophyll. 
The flowers are unisexual and thus proximity of male and female flowers is vital for successful pollination. These factors make successful pollination a rare event.
When Rafflesia is ready to reproduce, a tiny bud forms outside the root or stem of its host and develops over a period of a year.

All about JUPITER...

Image
Jupiter is the largest planet in the solar system. It is approximately 143,000 kilometers (about 89,000 miles) wide at its equator. Jupiter is so large that all of the other planets in the solar system could fit inside it. More than 1,300 Earths would fit inside Jupiter. Jupiter  is the fifth  planet  from the  Sun  and the  largest  in the  Solar System . Jupiter is primarily composed of  hydrogen  with a quarter of its mass being  helium , though helium comprises only about a tenth of the number of molecules. It may also have a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface. Surrounding Jupiter is a faint  planetary ring  system and a powerful  magnetosphere . Jupiter has at least  69 moons , including the four large  Galilean moons  discovered by  Galileo Galilei  in 1610.  Ganymede , the largest of these, has a d...

Sailing Stones....

Image
Sailing stones , also known as  sliding rocks ,  walking rocks ,  rolling stones , and  moving rocks , are a  geological phenomenon  where rocks move and inscribe long tracks along a smooth valley floor without human or animal intervention. Instead, rocks move when large ice sheets a few millimeters thick floating in an ephemeral winter pond start to break up during sunny days. These thin floating ice panels, frozen during cold winter nights, are driven by wind and  shove  rocks at up to 5 m/min. Trails of sliding rocks have been observed and studied in various locations, including Little Bonnie Claire Playa in Nevada,and most famously at  Racetrack Playa ,  Death Valley National Park , California, where the number and length of tracks are notable. The Racetrack's stones speckle the playa floor, predominantly in the southern portion. Historical accounts identify some stones around 100 m (300 ft) from shore, yet most o...
