Earth's one and only natural satellite have many secrets which are to be revealed.Our moon in ancient times was suitable to support life twice ,one 4 billion years ago and again in 3.5 billion years ago suggested by a study at Washington state University. According to the study it is believed that meteorites from earth with living cells and microbes were carried to the Moon. This was published in the Monday edition of journal Astrobiology . Two planetary scientists have stated in there study that during landing of meteorites on Moon created heat enough to melt ice water in the surface of the moon in water vapours and gases which spewed out from the moon surface and form water pools on moon. The study also stated that there was also stable atmosphere at that time with magnetic field wrapping whole moon enough to safeguard organisms on the moon from solar winds. Dirk Schulze Makuch an astrobiologist at Washington State University said that "There could have ac...

World's fastest spinning man made object Scientists create world's fastest spinning man made object. The object precisely is not a object but a nano particle which is in dumbbell shaped . The nano particle is made up of silica and was levitated by using laser in vacuum .  The noted rotation per second (rps) of the nano particle was about 60 billion rps .  Scientists behind this invention are Tongcang Li and Jonghoon Ahn .  Tongcang Li is assistant professor of physics and astronomy and also serve as assistant professor in computer engineering and electrical engineering in Purdue University .  According to Tongcang Li the dumbbell shaped particle was levitated in vacuum with using laser work.  The laser used having capability of working in a straight line and in circle helped in finding two motion of the nano particle   When the laser work in straight line the nano particle vibrates .  When the laser work in circle the dumbbe...
