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. ...

What if you fall into a black hole?

After getting bored from you lectures, assignments and exams, it's a good idea to go out for a spacewalk. Isn't it?😄 Oh wait! Jumping into a black hole seems to be a better one. Have you ever imagined the situation into a black hole ? What would happen if you enter into it? The reality might be weirder than your expectations. Well, a black hole is that cosmic mystery which may tear apart all the physical laws into pieces. So, you might have to think out of the box. Before entering into the black hole you have to pass the accretion disk which is too hot to be imagined, spitting out Hawking Radiation,  and finally the event horizon. Suppose, anyhow, you have succeeded in overcoming these nightmares, what's next?  There are the opinions of a few intellectuals about the further possibilities: 1. If you were to take a jump into a black hole, your body would most closely resemble "the toothpaste being pushed out of a tube," said Charles Liu, an astrophysi...

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...

Aditya L1, after Moon India's all set for the Sun

After the successful launch of chandrayan-2 ISRO is planning to cement its another pillar in the area of Aerospace. India is setting its foot on the Moon, then why leave the Life-giver, the Sun unexplored. Yes, you heard it right India is planning a new mission to study the Sun. The spacecraft named, " Aditya-L1 " (Aditya means the Sun)  has been chosen for this purpose. The mission will probably be started by the end of 2020. Things you must know about Aditya L1. It was originally named Aditya-1, which was made to carry just one payload, VELC (Visible Emision Line Coronogaph). Aditya-1 was a 400 kg satellite scheduled to be launched at 800 km from earth surface in low earth orbit. Later it was realized that if it is launched at " Lagarangian point ", it will be fee from any hinderance e.g. eclipse. Then the mission name was named Aditya L1 mission . [Lagarangian point is a point between earth and sun where the satellite will lie stably rel...

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 ...
