Time-lapse photography is a cinematography technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that which will be used to play the sequence back. When replayed at normal speed, time appears to be moving faster and thus lapsing. For example, an image of a scene may be captured once every second, and then played back at 30 frames per second; the result would be an apparent increase of speed by 30 times. Time-lapse photography can be considered to be the opposite of high speed photography.
Processes that would normally appear subtle to the human eye, such as the motion of the sun and stars in the sky, become very pronounced. Time-lapse is the extreme version of the cinematography technique of undercranking, and can be confused with stop motion animation.

The view from the International Space Station never ceases to amaze.
After all, at about 240 miles above, and orbiting at the Earth roughly 17,000 miles per hour, it offers a rare and spectacular view of the home planet.
A recent time-lapse video composed of a series of photos taken by the Expedition 30 crew on Dec. 29, 2011, shows Mother Earth in all her glory.
According to the NASA-Johnson Space Center, the video starts as the ISS passes over southeastern Niger in central Africa and continues to the Indian Ocean, southeast of Madagascar.
As the space station passes over Africa, lightning can be seen on the ground and the Milky Way looms on the horizon. The sun is beginning to rise over the Indian Ocean just as the video ends.
To give you an idea of how fast the ISS travels, the pictures in the video were taken over only a 20-minute period.
We had trouble seeing it, but NASA insists that the Lovejoy Comet is visible near the Milky Way. Let us know in the comments if you’re able to spot it.

Time-Lapse Video tutorial.
We’ll start by understanding some fundamental rules. Under normal circumstances, every one second in a video comprise of 24-30 frames of photos, calculated with the unit fps (frame per second). If you watch a 2 minutes video at 24 fps, that means it’s made up of 2880 photos (frames) animating at high speed.
To create Time-lapse effect, you basically reduce the interval for each shot and merge them into a 24-30 fps video. E.g., if the sun takes 12 hours to set and you take a photo every 1 minute, you will have 720 photos. With a 24 fps compression, you’ll have a video of sun rise to sun set in 30 seconds. Isn’t it amazing!

Sky will ‘Glow’ to night. Da Vinci Glow.
Normally Venus will glow in the later part of December and will be visible to the naked eye.Venus will be visible ,glowing in the early mornings in this month.
This is illustrated in Sri.Andal‘s ‘Thiruppavai’-Velli ezhunadadu,Vyazham urangitru’-Velli-Venus,Vyazhan-Jupiter.
These’ new findings’ are as old as Panchanga,Hindu Almanac , where celestial positions of Stars,planets and other activities are predicted every year very accurately,including Eclipses to the finest Degree.
It will be a sight to see this evening at dusk, as “Earthshine,” or sunlight reflected off the Earth, generates a ghostly illumination of the shadowed moon along with the crescent that will be in direct sunlight, the Columbus Ledger-Enquirer reports.
Astronomers named this visual effect “the Da Vinci glow” after Leonardo Da Vinci, who first figured it out.
This will not be the only celestial light to brighten the evening sky the day after Christmas. Venus will be prominent in the deep blue twilight, and the giant planet Jupiter will appear above it, in the constellation Pisces, NASA says.
Forming a triangle, the two planets and the moon will be the brightest lights in the night sky.
They can be seen with the naked eye, but a telescope will improve the view: “With a simple triangular sweep, you can see the clouds and moons of Jupiter, mountains and craters on the moon, and the fat gibbous form of Venus,” NASA says. “Rarely can so much amateur astronomy be done with so little effort.”

Largest Body of Water in Space Found.
Around a black hole 12 billion light years away, there’s an almost unimaginable vapor cloud of water–enough to supply an entire planet‘s worth of water for every person on earth, 20,000 times over.
Largest body of water in Space. Scientists have found the biggest and oldest reservoir of water ever–so large and so old, it’s almost impossible to describe.
The water is out in space, a place we used to think of as desolate and desert dry, but it’s turning out to be pretty lush.
Researchers found a lake of water so large that it could provide each person on Earth an entire planet’s worth of water–20,000 times over. Yes, so much water out there in space that it could supply each one of us all the water on Earth–Niagara Falls, the Pacific Ocean, the polar ice caps, the puddle in the bottom of the canoe you forgot to flip over–20,000 times over.
The water is in a cloud around a huge black hole that is in the process of sucking in matter and spraying out energy (such an active black hole is called a quasar), and the waves of energy the black hole releases make water by literally knocking hydrogen and oxygen atoms together.
The official NASA news release describes the amount of water as “140 trillion times all the water in the world’s oceans,” which isn’t particularly helpful, except if you think about it like this.
That one cloud of newly discovered space water vapor could supply 140 trillion planets that are just as wet as Earth is.

US Satelittes stumble over Tirunallar,India. NASA?
I received an email that states that satellites sent by US stumble and then recover when they cross over Tirunallaru in Puducherry State,India.
A temple dedicated to Lord Saneeswara is located here.
Saneeswara is the name given to Saturn, which according to Hinduism revolves around the Sun and it takes 30 years to complete a cycle.
The God that rules Saturn is calles Saneeswara.
The period when Saturn moves from one Zodiacal Sign to another , the event is called ‘Sani Peyarchchi'(movement of Saturn)
This is what is referred to in this news..
I have tried verification of this information.
Nothing is found in NASA site.
Can somebody send me information on this?
Story:
i got a mail that, A few years ago US sent a satellite which kept revolving round our globe
whenever it crossed right above the spot of Thirunallaar ( East Coast
Divine place of Tamil Nadu) it staggers, moves forward very slowly for a
while ! NASA observed it and was puzzled! It is also said that during the
SANI- PEYARCHCHI , a most sacred festival of the place, say once in 30
months , a very dense UV rays falls from the Space on the place ( it seems
there is always a greater flow of UV rays compared to the quota received by
any other part of our earth at that place ; and during the said festival
the density gets more!) No explanations from the Scientists.Is this true?
