NASA scientists have found the outer boundary of solar system and called it the hydrogen wall. Earlier, the space was believed to be a continuous expanse of an imaginary sheet called ether. Source: science news for students T he scientists working at NASA think that they have found the outer boundary of our solar system. It was earlier thought to be not properly defined. Now, they have said that their New Horizons spacecraft can see that invisible boundary. They have named it the "hydrogen wall." It is located at the edge of our solar system. The hydrogen wall has been described by the scientists as the place where bubbles of solar wind cease to exist. The mass of interstellar matter here is very small but strong enough to not let the solar winds to pass through. At the same time, it is not so strong to bust through the solar wind build up. It acts like a wall pressing the solar winds inward. The sun keeps throwing out jets of matter and energy in the form of solar winds. The...

Gaganyaan: A human trip to space The proposals have been sought by the Directorate of Human Space Programme of the Bangalore-headquartered ISRO for a total of 18 tentative technology development areas. The first manned mission of India to space ‘Gaganyaan’ is likely to take place around the year 2022. Gaganyaan space mission: For the development of indigenous technologies for sustained Indian human space programme as well as for space exploration, the Indian Space Research Organisation (ISRO) has recently invited proposals.  The proposals have been sought by the Directorate of Human Space Programme of the Bangalore-headquartered ISRO for a total of 18 tentative technology development areas. The first manned mission of India to space ‘Gaganyaan’ is likely to take place around the year 2022. At present, four Indian Air Force (IAF) fighter pilots are under training in Moscow, Russia, and they are likely to be potential candidates for the ‘Gaganyaan’ space mission, accordin...
