For alien hunters, two suns may be better than one

Recommended Posts

New research suggests that the gravitational arm-wrestling by a pair of suitably positioned parent stars should carve out a magnetically protected habitable zone for an orbiting brood.

“We need to be more open-minded when thinking about habitability of a significant fraction of the stars in the galaxy that are in binary systems that could provide enhanced habitability conditions,” astronomer Jorge Zuluaga with the Institute of Physics at the University of Antioquia in Colombia, told Discovery News. What goes into the detection of worlds orbiting other stars dozens of light-years away?

Zuluaga and colleagues focused on the impact a pair of orbiting stars would have on each others’ rates of rotation, which in turn affects how magnetically active they are. The specifics depend on how big and how far apart the two stars are, but generally computer simulations showed there could be magnetically quiet regions around binary stars, a finding that greatly expands their so-called "habitable zones" -- orbits where water could exist on a planet's surface.

Water is believed to be necessary for life, but it’s not the only factor. For example, in our solar system Venus and Mars, though situated in the sun’s habitable zone, presently do not have life-friendly atmospheres.

“We need to be more open-minded"

YES THEY DO, BUT I HAVE NEARLY GIVEN UP HOPE ON SCIENCE OPENING THEIR MIND TO ANYTHING  :)

Seems like science has a one track mind with memory blanks...
