The rare image showing both day and night on earth. Amazing!
The rare image showing both day and night on earth. Amazing!
The photograph attached was taken by the crew on board the Columbia during its last mission, on a cloudless day.
The picture is of Europe and Africa when the sun is setting. Half of the picture is in night. The bright dots you see are the cities lights. The top part of Africa is the Sahara Desert. Note that the lights are already on in Holland, Paris, and Barcelona, and that's it's still daylight in Dublin, London, Lisbon, and Madrid.
The sun is still shining on the Strait of Gibraltar. The Mediterranean Sea is already in darkness. In the middle of the Atlantic Ocean you can see the Azores Islands; below them to the right are the Madeira Islands; a bit below are the Canary Islands; and further South, close to the farthest western point of Africa, are the Cape Verde islands. Note that the Sahara is huge and can be seen clearly both during Daytime and night time. To the left, on top, is Greenland, totally frozen.

Girls Are precious their birth brings prosperity and luck to family ...
My grandmother did not come to see me till a month after my birth. I was born seven years after my only sister and my birth was a big disappointment for her. In it there is a message that I understand very well now about the discrimination against the girl child. My uncles and other relatives are against encouraging girls. My parents are more open. They back me all the way."

How to Drink Water?Check This Out
Water must be drunk in three separate breaths. In other words, the cup should be removed from the mouth after a sip, a breath taken and then drunk again. This method of drinking is very beneficial for quenching the thirst. When water enters the hot thirsty stomach in intervals, the second sip of water will quench the thirst left by the first, and the third will quench the thirst of the first two. This method will change the temperature of the stomach gradually. Sudden change of temperature inside the stomach is not desirable. When water is drunk in one sip, the gases in the stomach will ascend causing flatulence and stomachache
Sucking Your Thumb Gives You Buck Teeth.
Sucking Your Thumb Gives You Buck Teeth.For generations, parents have warned their children that sucking their thumb can give them buck teeth later in life. It may seem like an idea that would have gone the way of the Dodo, but it’s an entirely real possibility. Thumb-sucking is common among young children. But if it keeps going on when a child’s permanent teeth start to grow in, the teeth can become misaligned and, eventually, push top teeth out. If you want to avoid a pricey set of braces, encourage your child to stop sucking their thumb after they reach the age of 6!

5 Mind-Blowing Pictures and Video of the Moon
The image above of a "blue moon" (second full moon in a month) was captured by Simon Smith. It was "taken just hours before the exact full phase in delightfully clear skies over Nottingham, UK, it features eye-catching bright rays extending from the prominent young crater Tycho in the Moon's southern hemisphere." Continue reading to see more.
5. Harvest Moon
A Full Moon rising can be a dramatic celestial sight, and Full Moons can have many names. For example, Monday's Full Moon was the one nearest this year's autumnal equinox for the northern hemisphere, traditionally called the Harvest Moon.
According to lore the name is a fitting one because farmers could work late into the night at the end of the growing season harvesting crops by moonlight. This serene telephoto image captures this September's harvest moonrise from Turin, Italy. In silhouette against an orange lunar disk is Turin's hilltop Basilica of Superga.

4. Wolf's Moon
A Full Moon rising can be a dramatic celestial sight, and Full Moons can have many names. Captured on January 8 from Ostersund, Sweden, this evocative moonrise portrait might make you feel the cold of winter in the north. If you can also imagine wolves howling in the distance then you probably understand why Native Americans would have called it the Wolf Moon, their traditional name for the first Full Moon in January.
The photographer reports that no wolves were heard though, as he watched this beautiful Full Moon rise in fading light over the eastern horizon, echoing the yellow color of the setting Sun.

3. Moon Halo
Have you ever seen a halo around the Moon? This fairly common sight occurs when high thin clouds containing millions of tiny ice crystals cover much of the sky. Each ice crystal acts like a miniature lens. Because most of the crystals have a similar elongated hexagonal shape, light entering one crystal face and exiting through the opposing face refracts 22 degrees, which corresponds to the radius of the Moon Halo.
A similar Sun Halo may be visible during the day. The setting of the above picture is Athens, Greece. The distant planet Jupiter appears by chance on the halo's left. Exactly how ice-crystals form in clouds remains under investigation.

2. Super Moon vs. Micro Moon
Did you see the big, bright, beautiful Full Moon Wednesday night? That was actually a Micro Moon! On that night, the smallest Full Moon of 2012 reached its full phase only about 4 hours before apogee, the most distant point from Earth in the Moon's elliptical orbit. Of course, earlier this year on May 6, a Full Super Moon was near perigee, the closest point in its orbit.
The relative apparent size of November 28's Micro Moon (right) is compared to the famous May 6 Super Moon in these two panels, matching telescopic images from Bucharest, Romania. The difference in apparent size represents a difference in distance of just under 50,000 kilometers between apogee and perigee, given the Moon's average distance of about 385,000 kilometers. How long do you have to wait to see another Full Micro Moon? Until January 16, 2014, when the lunar full phase will occur within about 3 hours of apogee.

1. Driving on the Moon
What would it be like to drive on the Moon? You don't have to guess -- humans have actually done it. Pictured above, Apollo 16 astronauts John Young and Charles Duke recorded video during one such drive in 1972, with a digital version now available on the web. No matter which direction it headed, the Lunar Rover traveled a path literally covered with rocks and craters.
The first half of the above video shows the rover zipping about a moonscape near 10 kilometers per hour, while the second half shows a dash-cam like view. The Lunar Rover was deployed on the later Apollo missions as a way for astronauts to reach and explore terrain further from the Lunar Module basecamp than was possible by walking in cumbersome spacesuits. Possible future lunar missions that might deploy robotic rovers capable of beaming back similar videos include those by China, Russia, India, and Google X-Prize contestants.

Black Mamba General Knowledge Facts
- Black mambas use their incredible speed to escape threats, not to hunt prey.
- Black mambas are fast, nervous, lethally venomous, and when threatened, highly aggressive.
- They have been blamed for numerous human deaths, and African myths exaggerate their capabilities to legendary proportions. For these reasons, the black mamba is widely considered the world’s deadliest snake.
- Black mambas live in the savannas and rocky hills of southern and eastern Africa.
- They are among the fastest snakes in the world, slithering at speeds of up to 12.5 miles per hour (20 kilometers per hour).
- They get their name not from their skin color, which tends to be olive to gray, but rather from the blue-black color of the inside of their mouth, which they display when threatened.
- Black mambas are shy and will almost always seek to escape when confronted. However, when cornered, these snakes will raise their heads, sometimes with a third of their body off the ground, spread their cobra-like neck-flap, open their black mouths and hiss.
- If an attacker persists, the mamba will strike not once, but repeatedly, injecting large amounts of potent neuro- and cardiotoxin with each strike.
- The mamba's venom contains a powerful neurotoxin which works by preventing impulses from travelling along the nerves. The victim becomes paralysed and death occurs through respiratory failure.
- Black mambas spend their nights in holes in the ground - usually disused burrows - or hiding deep among fallen rocks or timber. These hiding places are also fled to by the snake if it becomes alarmed and it will attack any creature blocking the path to its hole.
- Black mambas travel quickly across rough ground or along low tree branches when hunting. They are able to hold their heads up to 1m above the ground when striking and can hold them 50cm above the ground even when moving
- Females lay between 10 and 25 eggs, usually in decaying vegetation.
- Black mamba hatchlings are around 51cm long, and greyish-green in colour. They are independent immediately and can catch prey the size of a small rat. Within a year they reach 2m.
- Young mambas are eaten by mongooses, and even adult mambas are eaten by the secretary bird and larger species of eagle.
