Jupiter's moon Europa — with its icy shell and subsurface ocean — has long sparked the imaginations of scientists and science fiction writers alike.

What's new: Newly reprocessed images first taken in the 1990s by NASA's Galileo spacecraft show the moon's "chaos terrain" in new relief.

  • The bright white and blue regions are made of water ice, while the reddish color is caused by salts and other minerals, according to NASA.

What's next: Researchers are particularly interested in learning more about Europa because the moon is thought to be one of the best places to hunt for possible life in the solar system.

  • Scientists are hoping to use these newly processed photos to help with planning for NASA's Europa Clipper mission, expected to launch in the 2020s to perform a series of flybys to study the moon from close range.

Silicon Valley may be a "state of mind," but it's also very much a real enclave in Northern California. Now, a growing faction of the tech industry is boycotting it.

Why it matters: The Bay Area is facing for the first time the prospect of losing its crown as the top destination for tech workers and startups — which could have an economic impact on the region and force it to reckon with its local issues.

As teleworkers flit from city to city, they're creating a huge tax mess.

Why it matters: Our tax laws aren't built for telecommuting, and this new way of working could have dire implications for city and state budgets.
