NASA Hubble Telescope Spots Ocean On Jupiter’s Moon Ganymede
NASA’s Hubble Space Telescope has spotted massive salt water ocean under the icy crust of Jupiter’s largest moon Ganymede. Scientists believe that this finding could potentially support life. Hubble Space Telescope’s finding was pushed in the Journal of Geophysical Research: Space
Physics. The finding was based on the results obtained after analysing Ganymede’s magnetic field and aurora created and controlled by it and its interaction with Jupiter’s magnetic field.
Scientists estimate that this ocean is 100 kms thick and it is 10 times deeper than Earth’s oceans. It is buried under a 150-kilometre crust of mostly ice. In 1970s, for the first time scientists had suggested that ocean is present inside Ganymede based on its models. NASA’s Galileo mission also had provided first evidence of ocean in Ganymede after measuring its magnetic field in 2002. Ganymede is the largest moon in our solar system. It is also the only moon with its own magnetic field. The magnetic field causes aurora, which are ribbons of glowing, hot electrified gas, in regions circling the north and south poles of the moon

Pakistan Tests 1st Indigenous Armed Drone, Laser-Guided Missile
Pakistan on March 13, 2015 successfully tested its first indigenous all-weather armed drone and a laser-guided missile that can strike its targets with pinpoint accuracy. Chief of Army Staff Gen. Raheel Sharif attended the ceremony and witnessed the test-fire of the new missile on static and moving targets.
The drone, named Burraq, has the ability to fly in all types of weather conditions and strike its targets with pinpoint accuracy. Pakistan also tested its laser-guided missile named Barq. Gen. Sharif said this newly developed arsenal will increase the military’s capacity in fighting terrorism.
The Pakistan Army announced that a very effective force multiplier had been added to the inventory of the armed forces. In November 2013, the military had indigenously developed surveillance-capable drones. The induction of two unmanned aerial vehicles (UAVs), called the ‘Burraq’ and ‘Shahpar’ systems, in the Pakistan Army and Air Force was seen as a landmark and historic event. Pakistan already has several types of unarmed surveillance drones in operation, but Burraq and Shahpar were the first surveillance drones to be developed locally
