an earthlike planet Gliese 581c under libra constellation: Astronomers have discovered a planet (or exoplanet) 5 times as massive as the Earth orbiting a dim red star known as Gliese 581 which is located about 120 trillion miles away from planet earth.
Plants growing on other planets are likely to be coloured the whole spectrum of the rainbow except for blue, researchers have concluded.
Two studies carried out on the likely appearance of extra-terrestrial undergrowth suggest that it is as likely to be red or yellow as green.
Astrobiologists said that the colour of the plants, if they exist, will be dependent on the quality of light available from their local sun. The studies were carried out to help to guide the search for life on other planets by identifying the colours that astronomers should search for.
On Earth the commonest colour of foliage is green because it is the shade that is of least use to the plants from the spectrum of light emitted by the sun when they photo-synthesise. The spectrum of light from other stars will differ, and plants growing on other planets are expected to evolve to take advantage of the best available light.
discovered by the European Southern Observatory's telescope in La Silla, Chile, the planet is circling a red dwarf star, that goes by the name Gliese 581. the star is much cooler than our sun of course.
these stars are low-energy, and last longer than other stars as they fuse lesser hydrogen, obviously because they are low energy and should "last" longer than our sun.
hopefully more exoplanets could be discovered to support our human population after 8 billion years.
now for the bad news.. Gravity on planet 581c is 1.6 times stronger than earth's so you are going to walk a little slower and need a good pair of lightweight shoes. and those who have problems with fitness. i'll rather we stick to earth for the time being.
