SPACE RADIATION: According to a new study just published in the research journal Space Weather, astronauts face a growing peril from space radiation. Rising fluxes of cosmic rays inside the solar system place increasingly strict limits on the amount of time explorers can safely travel through interplanetary space.

AURORA WATCH: Arctic sky watchers should be alert for auroras this weekend. Earth is passing through a fast-moving stream of solar wind, and this is causing geomagnetic unrest around the poles. Geomagnetic storm alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
