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 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.
Prepare yourself for new royalty shaped in the form of mice. But that’s not just any mice, these are mice with the DNA of the king of rock and roll. For his “All That I Am” project, Koby Barhad used the DNA of Elvis Presley in genetically engineered mice. The idea is to explore ethical and philosophical concerns, ranging from questions of talent, to the ownership and legal rights tied to using someone else’s genetic data.
The suit Neil Armstrong wore when stepping onto the moon was made using cutting edge technology of that time. A good part of that technology and suit construction came from a bra manufacturer in Dover, Delaware. The suit had to live up to a whole range of specifications, a very important one being that it be capable of containing the pressure necessary to support life i.e. 3.75 pounds per square inch of pure oxygen.
This spectacular image is the result of the eruption of a magnetic filament of solar material. Captured in late September, the image shows a 200,000 mile long filament that erupted through the sun’s atmosphere, the corona. The ‘canyon of fire’ was formed where magnetic fields held the filament aloft before the eruption.
A very, very horrifying list of parasites and their ways. It’s almost morbidly fascinating.
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.
New video from ASAP Science discusses if our brain could be hacked, the big biological computer that it is.
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.
No time to read Stephen Hawking’s A Brief History of Time? In just two and a half minutes, Alok Jha explains why black holes are doomed to shrink into nothingness then explode with the energy of a million nuclear bombs, and rewinds to the big bang and the origin of the universe.
