Two Suns? Twin Stars Could Be Visible From Earth By 2012. By Dean Praetorius | HuffingtonPost.com Earth could be getting a second sun, at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news.com.au. Betelgeuse, one of the night sky’s brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time. When that happens, for at least a few weeks, we’d see a second sun, Carter says.

There may also be no night during that timeframe. The Star Wars-esque scenario could happen by 2012, Carter says... or it could take longer. But doomsday sayers should be careful about speculation on this one. In fact, a neutrino shower could be beneficial to Earth.

The Tristram Shandy Web | IULM. Robert Hookes Micrographia. Earths True Shape Revealed for 1st Time. After two years in orbit, the European Space Agency’s (ESA) Gravity field and steady-state Ocean Circulation Explorer (GOCE) is nearing the end of its planned life span in February, producing the most accurate map ever of the so-called geoid -- an Earth-encompassing spirit level and global reference surface. An unused supply of xeon fuel will allow the mission to be extended until at least the end of 2012. Markedly different from a simple sphere or ellipsoid, the geoid is the mathematically 'true' shape of Earth. It represents a motionless global ocean but takes into account the effects of the Earth’s rotation, weight difference resulting from the position of mountains and ocean trenches, and uneven mass distribution and density variations in the planet’s interior.

The resulting small variations in the Earth’s gravitational field feature on the geoid as ‘bulbs’ and ‘dips’ in an idealized ‘ocean’ surface. The Daily Galaxy via ESA. First habitable exoplanet confirmed. Gliese 581d is the outlying planet in the Gliese 581 system, and orbits its parent star every 66.8 days. It may be covered by a large and deep ocean and is the first serious 'waterworld' candidate discovered beyond our Solar System.

Modelling of planet Gliese 581d shows it has the potential to be warm and wet enough to nurture Earth-like life, scientists have said. It orbits a red dwarf star called Gliese 581, located around 20 light years from Earth, which makes it one of our closest neighbours. Gliese 581d orbits on the outer fringes of the star’s ‘Goldilocks zone’, where it is not so hot that water boils away, nor so cold that water is perpetually frozen. Zarmina’s World More than 500 planets orbiting other stars have been recorded since 1995, detected mostly by a tiny wobble in stellar light. No doubt that it exists.
