When stellar metallicity sparks planet formation
New research predicts the criteria needed for Earth-like planets to form around a star that have one-tenth the metallicity of our Sun. If researchers find small, rocky planets orbiting stars with lower metallicity, ...

'Tidal Venuses' may have been wrung out to dry
Earth-sized exoplanets within a distant star’s habitable zone could still be very much uninhabitable, depending on potential tidal stresses — either past or present — that could have "squeezed ...

The stellar superhighway in the Milky Way
Conventional wisdom suggests that, like planets round the Sun, stars follow approximately circular orbits which cross the spiral arms, and that the Sun presently lies in a spur rather than a major spiral arm.
