Scientists Discovered Two New Earth-like Planets: The Scientists at the Harvard-Smithsonian Centre for Astrophysics have discovered two Earth-like planets Kepler 438b and Kepler 442b. The findings of the discovery were published in The Astrophysical Journal on 5 January.The planets were spotted by Nasa’s Kepler space telescope which detects planets as they move across the faces of their stars. Kepler 438b is 475 light years away. It gets about 40 percent more heat from its red sun than Earth gets from the Sun.Kepler-442b is 1100 light-years away. It is 33 percent bigger than Earth and orbits its star once every 112 days. has a 60-percent chance of being rocky. IAF gets First Indigenously Built LCA Tejas: First indigenously-built Light Combat Aircraft (LCA) Tejas was handed over to the Indian Air Force (IAF) by Defence Minister Manohar Parrikar at ceremony held on 17 January at Bengaluru, Karanataka.It received its Initial Operational Clearance-I in January 2011, after being built by state-owned HAL. It is expected that the aircraft will receive its Final Operational Clearance by December 2015. India Successfully Test-Fired Inter-Continental Ballistic Missile Agni-V: India on 31 January successfully test-fired its indigenously developed, intercontinental surface-to-surface nuclear capable ballistic missile ( ICBM) ‘Agni-5′, which has a strike range of over 5000 kms and can carry a nuclear warhead of over one tonne, from Wheeler’s Island off Odisha coast. This was the third successful flight test of the Inter-Continental Ballistic Missile (ICBM) and the first canister trial. The first test was conducted on April 19, 2012 and the second test on 15 September, 2013 from the same base. NASA Launches SMAP Satellite: National Aeronautics and Space Administration (NASA) has on 2 February launched Soil Moisture Active Passive (SMAP) satellite to observe soil moisture.It was launched from the Delta 2 rocket from Vandenberg Air Force Base in California. SMAP satellite is three-year mission which will measure the amount of moisture in soil. It will produce high-resolution global maps from space and data collected from it will help scientists to monitor droughts and improve flood forecasts.
