The dog days of summer
The dog days of summer
Is it hot enough for you? Chances are it is, as we get into what are typically the hottest months of the year in the Northern Hemisphere, thanks to the tilt of the Earth angling more towards the sun in summer. You may have heard this sweltering period called the dog days of summer, though that name doesn"t come from hot dogs or panting pooches. Rather it comes from Sirius, the Dog Star, which becomes visible above the eastern horizon at daybreak during the summer. Sirius is the brightest star in the night sky, and is part of Canis Major, not to be confused with the Canis latrans, or coyote, in today"s image, who is just trying to beat the heat.Desktop Version

Tasmans Arch, Tasmania, Australia
Tasmans Arch, Tasmania, Australia
Ready for a coastal adventure? Welcome to Tasman National Park in Tasmania, an island state of Australia about 150 miles off its southeastern coast. Spanning more than 41 square miles, this park features dramatic cliffs and distinctive columns of dolerite rock. Tasmans Arch, seen in today"s image, is a standout example. Shaped over time by the Tasman Sea, it was once the roof of a massive sea cave. The sea"s pressure, combined with air, sand, and stones, slowly pried open the vertical cracks in the cliff, dislodging chunks of rock. The cave kept growing, deepening, and lengthening, until it eventually gave way, leaving behind this towering natural bridge. Tasmans Arch is named after the Dutch explorer Abel Tasman, who also lends his name to the state of Tasmania.Desktop Version

World Lizard Day
World Lizard Day
From mythology to movies, lizards have often been portrayed as scary reptiles. But they"re not as dangerous as stories might lead you to believe. World Lizard Day is the perfect time to learn about these cold-blooded creatures. With more than 7,000 species, lizards have adapted to a wide range of environments—from deserts to rainforests. Take geckos—these little climbers have toe pads that let them scale walls and walk on ceilings. Then there are chameleons with their color-changing skin. While many think it"s all about blending in, this ability is also used to communicate and regulate temperature.Desktop Version
