Melbourne, July 9 (ANI): British theoretical physicist Stephen Hawking has revealed his idea on how aliens might really look in a new documentary series, 'Into The Universe'.

Hawking, 68, who is paralysed due to motor neurone disease, spent three years to finish the series, which will air this weekend on the Discovery Channel.n the first episode he suggests that extraterrestrials are almost certain to exist, as with 100 billion galaxies existing, each with hundreds of millions of stars, there has to be other planets that can sustain life like earth.

"To my mathematical brain, the numbers alone make thinking about aliens perfectly rational," the Courier Mail quoted him as saying.

"The real challenge is to work out what aliens might actually be like," he said.

Among the theoretical aliens are terrestrial herbivores and carnivores, lizard-like predators with limb membranes that allow them to glide using venom-loaded stingers to bring down a two-legged herbivore that has a huge vacuum snout to suck up food.

Such land-based aliens would probably feed and move in ways similar to animals on Earth.

Prof Hawking also came up with a squid-like creature that could feed on the bottom of the salty ocean thought to exist below the icy crust of Jupiter's moon Europa.

Life on planets where the average temperatures are below -150C would require organic components and physiologies radically different than those found on terrestrial planets largely dependent on liquid water. (ANI)
