Earth under attack from Nemesis

Scientists have claimed that an invisible star which is supposed to be 5 times the size of Jupiter is kicking some deadly comets towards Earth.

They believe that the invisible which is nicknamed as " Nemesis" or " The DeathStar" could be responsible for mass extinction on Earth which occurs every 26 million years.

The stars spins through the galaxy and its gravitational pull drags a vast sphere of rock called Oort Cloud and dust twice as far as Nemesis. They are thrown towards Earth as comets which is causing destruction .

NASA scientists believe that they will be able to find about Nemesis using a new heat-seeking telescope that began scanning the skies in January. Researchers have come to know about the existence of Nemesis from orbit of a dwarf planet called Sedna.

The Wide-Field Infrared Survey Explorer which has found a thousand brown dwarf stars within 25 light years of the Sun has sent a photo of a comet disloged from the Oort Cloud.
