Cassini's latest discovery about Titan's lakes

Titan , the largest satellite of Saturn and second largest known satellite in our solar system, is much weirder than we might think. It is the only heavenly body, after earth, that contains surface liquids in stable forms and only moon with dense atmosphere. Cassini , a collaborative mission between NASA, ESA and ASI, has unveiled many secrets about Titan so far. The latest imagery from the Cassini probe claims that Titan's lakes may have been formed by exploding nitrogen bombs. Yes. their exist Nitrogen, an essential component for all life forms. Titan is mostly composed of icy and rocky materials. Scientists had long believed that these infamous lakes are a result of melting bedrock of ice by Methane. But a new data gathered by Cassini speaks otherwise. The nitrogen exploded below the surface due to increasing temperature resulting in craters, which were filled with liquids later.  No wonder, why NASA is planning a mission to explore this mysterious world by 2026. ...

How do you remember stuffs?

Memory is so fundamental to human behavior that any impairment to it can severely impact our daily life. Did it ever happen that you forgot the name of the person you just met? How do we remember some stuffs for decades and some fade after a few moments? What actually is that makes the difference between long-lasting memories and volatile ones? After several tests on mouse, Caltech researchers have finally discovered that the strong memories are results of the synchronized "teams of neurons" that provide redundancy to retain memories over long time. The team of researchers developed a test to study mice's neural activity as their brain resembles that of human in many ways. The result showed that more the quantity of neurons, longer will the memory last. For years, people believe that practicing an action more, brings better chance to remember it later as the conventional theories about  human memory storage say that making a memory more stable requires the s...

The concept of Black Hole

Don't be fooled by its name. A black hole is not really a hole as its name suggests. Before diving into the topic let's first be familiar with a few terms. Image of a Black Hole Escape velocity - The lowest velocity with which when an object is thrown from any cosmic body [planets, stars etc] escapes or moves out of its gravitational pull. The escape velocity of the Earth is 11.2 Km/s. Event Horizon - The boundary after which no light or other radiation can move out after striking a black hole. Light cant escape out completely from the pull of a black hole but it does come to a certain limit, that's event horizon of a black hole. A Black Hole is a super dense, massive object with an infinitesimally small volume having escape velocity higher than the velocity of light. And nothing can move faster than light so, nothing can escape out of a black hole. This is the reason it appears completely dark because even light can't reflect back from it. Think of a star...

Do you know??? WhY...

1. Why there are curls drawn at the center of moving turbine in an airplane jet engine? Ans. You must be aware of the fact that the jet engines of any commercial airplane are capable of sucking an adult if he/she passes before it. The human body cuts into pieces and a red soup like thing drains out from the back of the jet engine. To avoid this type of accident, and to inform the workers whether the engine is ON or not, a curl is drawn in the front which when rotates seems like a spinning whirlpool. It also helps in keeping out birds. 2.Why lights in the passenger cabin dims during take-off and landing? Ans. If you have ever been in an airplane, you must have observed that the lights inside the passenger cabin are dimmed during take-off and landing, at night. This is because of the fact that 80% of air accidents occur during take-off and landing. And our eyes might take about 10 mins to adapt in the darkness after a sudden light-off condition. To aid the chances of surv...

10 interesting facts about human body.

Did you know these interesting facts??? 1.A human can snore louder than a drilling machine. 2.Our tongue prints are unique just like our fingerprints. 3.The electricity generated in our brain is capable enough to light a small bulb. 4.the hair present on a human head can lift weight up to 10 tonnes. 5.Our body contain enough iron to make small nail. 6.We can't sneeze with both our eyes opened. 7.Almost 8% human in the world are color blind. 8.We shiver in cold because it generates heat. 9.When you sneeze, your heart stops for a milisecond. So, when someone says, "God bless you" after you sneeze, he/she really cares for you. 10.Every human spent about half an hour as a single cell in the womb.

Things You must know about Chandrayan-2

India’s second mission to the moon is more advanced than the first. The space shuttle will explore the southern part of the moon making India the first country to do so. It will carry 13 satellites with total weight of about 3.8 tones, Sivan said. Chandrayaan-2 is India’s second lunar mission with three modules 1.The Orbiter 2.Vikram, The lander and 3.Pragyan, the Rover The Orbiter and Lander will be mechanically stacked together as an integrated module inside the launch vehicle, GSLV Mk-III aka "The Bahubali". This mission is being refered as the most complex one ever undertaken by ISRO. Pragyan* will make a soft landing on lunar surface unlike it predecessor the Chandrayan-1. The mission cost of Chandrayaan-2 with regard to the satellite was Rs 603 crore. The cost of GSLV MK III is Rs 375 crore. this is India’s first interplanetary mission to be steered by two women, M Vanitha as Project Director and Ritu Karidhal as Mission Director. The scientists of ...
