Washington, Feb 18 - Scientists have discovered that stars, which are similar to the sum, explode too when they die.

The birth of planetary nebulae, resulting from the death of low and intermediate mass stars, is usually thought of as a slow process, in contrast with the intense supernovae that massive stars produce. But a recent study led by researchers at the Institute of Astrophysics of Andalusia (IAA-CSIC) has revealed the fact that explosive phenomena also intervene in the formation of planetary nebulae.

Washington: NASA is planning to send a nuclear-powered submarine to explore one of the methane seas located on Saturn's moon Titan.

The single-tonne concept robot submarine is equipped with a seafloor camera and sampling system.

The submarine could fit into a space plane such as Boeing's X-37, which was recently used for a classified Air Force mission.

The plane could land on Kraken Mare, the largest known body of liquid on Titan that consists mostly of liquid methane, or possibly drop the submarine using a parachute, 'ibtimes. Com' reported.

"The vehicle would use conventional propulsors to yaw around, using a sun sensor to determine the initial azimuth to Earth and begin communication using a terrestrial radio as a more precise reference," NASA said.
