An Excellent Visualization of Gravity

We know gravity, but visualizing it on the fabric of space-time can be a bit daunting. This excellent video shows a simple way to visualize gravity, and on its way plays along with some pretty interesting facts and trivia. It is about 10 minutes long, but it is 10 minutes well spent.

India’s Mars Orbiter Sends Home Its First Image

First image of earth from Indias Mars Orbiter Mission

India’s first mission to Mars, the Mars Orbiter (Mangalyaan) crossed the distance of the moon’s orbit this morning, making it the farthest object sent into space by India. A few days ago, the spacecraft looked back, and sent a postcard back home. This is the first image of Earth taken by the Mars Color Camera (MCC) aboard the Mars Orbiter Spacecraft. The image was taken on November 19, from an altitude of 67975 kilometers.

Watch Water Droplets Run Through a Metallic Maze and Amaze [video]

Watch Water Droplets Run Through a Metallic Maze and Amaze [video]

Leidenfrost effect is the phenomenon responsible for the jumping water droplets that happen when you pour water on a hot pan. Basically, as water comes into contact with a surface way above its boiling temperature, a thin layer of vapor forms at the contact point and prevents the droplet from evaporating suddenly. Put a bit of effort into the scenario, and water droplets can be made to move in specific directions.

Watch the Birth of a New Island Off the Coast in Pakistan Through Satellite Images

Watch the Birth of a New Island Off the Coast in Pakistan Through Satellite Images

After last week’s huge earthquake in Pakistan, a new island appeared off the coast of Karachi. The incident was seen by NASA’s Earth Observing (EO-1) satellite, which has these images to show. The island is a flammable gas emitting landform that is being called a mud volcano. There is a chance that the island might not last long, though it is currently visible and has also been visited.
