Recently, an astronomer in Sweden watching Mars witnessed a rare green flash. Visit Spaceweather.com for a video of the phenomenon and more information about the Martian brightening. 

FLIGHT ATTENDANTS' RADIATION RISKS

On the heels of a new study showing that flight attendants have an elevated risk of cancer compared to the general population, Spaceweather.com and the students of "Earth to Sky Calculus" recently boarded a plane to New Zealand carrying an array of cosmic ray sensors. During their 13-hour flight across the South Pacific, the team detected secondary cosmic rays in the passenger compartment almost 40 times stronger than on the ground below. Their "haul" of radiation included a significant number of neutrons captured in portable bubble chambers. Read Spaceweather.com for the full story.

GREEN COMET APPROACHES

A comet that could become visible to the naked eye in August has exploded in brightness, suddenly increasing its luminosity 16-fold. Whatever happened on Comet PANSTARRS (C/2017 S3) on July 1 has given it an expanding green atmosphere almost twice the size of the planet Jupiter.
