ARE WE ALONE? It’s one of the fundamental questions of humanity, and chances are we’ll be hollering the question into the vastness of the universe for centuries to come – someday, we may just get an answer. When that answer comes, it may be anything from a War of the Worlds-style invasion; to a sniff of the […]
FROM NEAR-EARTHS TO BIZARRE planets with oven-hot surfaces, comet-like tails or a seasonal temperature variations of 700°C, our galaxy is filled with a host of weird and wonderful worlds. So far more than 350 exoplanets – planets that orbit other stars – have been discovered, and that’s just the tip of the iceberg. Future sky surveys […]
THE TARGET PLANET is ‘Gliese 581d’, a super-Earth about eight times heavier than our own planet. Gliese 581d and its three known sister planets orbit the low-mass red dwarf star Gliese 581, about 20.3 light-years (194 trillion km) away from us, in the constellation Libra. Imagine life from the surface of this planet – its […]

What is an exoplanet anyway? EXOPLANETS, OR EXTRASOLAR planets, are planets in orbit around stars other than the Sun (which is the nearest star to Earth). More than 350 have been discovered so far… more information. Why Gliese 581d? With at least two potentially habitable planets and the most Earth-like planet discovered so far, the Gliese 581 […]
ARE WE ALONE in the universe? Is there life on other planets? Are there other civilisations in our galaxy? How life began, and whether it exists elsewhere, is a fascinating question which we still cannot answer. Of the eight planets in our Solar System, only one – Earth – has life, as far as we know. […]
