We have a science work to write how the earth is now and then translate it into bangla. If u all have any idea tell me and it would be better if u translate it in bangla if not u can give me site where i can translate it. And if u cant do any just give me the idea of how the earth is now.

For the first time, Earth has a regular orbiting eye-in-the-sky spying on the solar system's smallest and strangest planet, Mercury. NASA's spacecraft called Messenger successfully veered into a pinpoint orbit Thursday night after a 6 1/2-year trip and 4.9 billion miles and tricky maneuvering to fend off the gravitational pull of the sun. It is the fifth planet in our solar system that NASA has orbited, in addition to the Earth and the moon. Mercury is not only difficult to get to, but it's has some of the most extremes in the solar system. Temperatures there swing wildly by 1,100 degrees. While it gets up to 800 degrees on the planet closest to the sun, it also is so cold and dark in some craters that the temperatures don't get above 300 degrees below zero. Radar even shows that there is likely frozen ice in those craters, something Messenger will try to confirm. In the 1970s, NASA sent a spacecraft, Mariner, whizzing by Mercury, but only got pictures of less than half of the tiny rock. Robert Strom of the University of Arizona was a scientist on the Mariner and current Messenger missions and he said for a while he thought he wouldn't get a second peek at the eccentric Mercury. Strom said he and all his colleagues were nervous as the desk-sized spacecraft automatically shifted into an egg-shaped orbit, with controllers on Earth unable to change commands because it took eight minutes for signals to travel the approximately 100 million miles from Mercury to Earth.
