On the June solstice, the sun will set at the same time in New York City and St. Augustine, Florida. But New York will have an hour more of daylight. How’s that happen?
It’s getting harder for wild animals to find human-free spaces on Earth. New research suggests that human disturbance is creating a more nocturnal natural world.

A rainforest canopy can reach 15 to 20 stories high. It’s an ecosystem unto itself. Now – to study drought effects – scientists have made the 1st 3D measurements of rainforest canopies in the Brazilian Amazon.
We’re talking about the number of minutes it takes for the body of the sun to sink below your western horizon. Fastest at the equinoxes, slowest at the solstices.
A June solstice sunset - June 21, 2013 - in the nation of Oman, on the Arabian Peninsula, from our friend Priya Kumar. Thank you, Priya!
The solstice happens this week. Longest day for the Northern Hemisphere. Shortest day for the Southern Hemisphere. Either way … a good time to celebrate!
From the December solstice to the June solstice, the sunset makes its way north, as illustrated in this photo composite by Abhijit Juvekar. Thanks, Abhijit!
Over several days this weekend, the moon swept near the brightest planet, Venus, in the west after sunset. Thanks to all who contributed photos! Editor’s picks, here …
Kilauea volcano’s Fissure 8 has produced a large, channelized lava flow that’s acted like a river, eating through the landscape, finally producing clouds of steamy, hazardous “laze” as hot lava meets the cold ocean.
Check out this amazing page - compiled yesterday - of photos and videos from Kilauea volcano in Hawaii. It's from the Hawaiian Volcano Observatory: https://on.doi.gov/2kaApVt
Photo shows Fissure 8 of the volcano. Fissure 8 fountains reached heights up to 160 feet overnight on Friday. Lava fragments falling from the fountains are building a cinder-and-spatter cone around the vent, with the highest part of the cone (about 125 feet high) on the downwind side.

Could life exist on planets in the star system closest to ours, Alpha Centauri? Dangerous X-ray radiation makes it unlikely for the single exoplanet found so far. But new data suggest better odds for any new planets yet to be discovered.

Scientists just learned that honeybees can understand the concept of zero. That puts bees in an elite club of clever animals – some birds, monkeys, humans – that can grasp the abstract notion of nothing.
