In 2008, a group of activists climbed into the canopy of a Humboldt County redwood forest and didn't come down for four years—after the owner of the land announced a deal to transfer more than 1,000 acres to a public trust, including the occupied trees.

A new video shows planets circling a star light-years away.
Here's what you're looking at. The black circle in the center is the young 30-million-year-old star, around 1.5 times the mass and 4.9 times the brightness of the Sun.
The innermost exoplanet is HR8799e, with a mass of 7.4 Jupiters orbiting at a distance of 16.25 times the separation between Earth and the Sun, or astronomical units, for an orbital period of 45 years. Scientists have been able to analyze the light from this exoplanet to determine that it's a storm-wracked baby gas giant.
