Are we looking in the wrong place for ET?
Scientists suggest 'footprints' on moon
could be best place to look for alien life
Scientists suggest 'footprints' on moon
could be best place to look for alien life
- Alien missions to moon likely to have been long ago
- Moon would preserve traces for millions of years
- Easier to find alien debris than radio signals
- Nasa's Lunar Reconnaissance Orbiter may have captured pictures of 'footprints' of ancient aliens
But two astronomers suggest that we may be missing evidence much closer to home.
Two scientists at Arizona State University have suggested that alien life may have 'left traces on the moon in the form of an artifact or surface modification of lunar features' - and that alien 'footprints' on the moon would last far longer than radio signals.
The detailed moon maps created by Nasa's Lunar Reconnaissance Orbiter may be the best place to look for alien life, say scientists - evidence such as trails or debris would remain there for millions of years, and be easier to 'catch' than radio signals
New astronomy software creates the first
accurate visions of other worlds - including
what Earth looked like 240 million years ago

Astrobiologist Abel Mendez of the University of Puerto Rico at Arecibo has designed a software package that can draw real-looking worlds based on the scientific data we receive from space telescopes - and says Nasa gets it wrong.
Mendez's software package draws planets based on their size, distance from their parent star and chemistry - and can create 3D images that correspond to the data.
The imagery sent out when missions such as Nasa's Kepler telescope find 'exoplanets' - planets outside our solar system - is still imagined by artists. Mendez claims that his approach is more scientific.
A warm, earthlike planet orbiting a red dwarf star. Mendez's software lets astronomers enter the data they know about a planet and then constructs a vision of what it might look like
