Astronomers: ‘Tilt-a-worlds’ could harbor life

A fluctuating tilt in a planet’s orbit does not preclude the possibility of life, according to new research. In fact, sometimes it may help. That’s because such “tilt-a-worlds,” as astronomers sometimes call them — turned from their orbital plane by the influence of companion planets — are less likely than fixed-spin planets to freeze over, as heat from their host star is more evenly distributed.
