Two words: Whoa, Nelly.
In a landmark study, scientists using NASA's Hubble Space Telescope have mapped the immense envelope of gas, called a halo, surrounding the Andromeda galaxy, our nearest large galactic neighbor. Scientists were surprised to find that this tenuous, nearly invisible halo of diffuse plasma extends 1.3 million light-years from the galaxy—about halfway to our Milky Way—and as far as 2 million...
Nearly half of all US states have mandatory Complete Streets policies, according to new data published today to LawAtlas.org.
Mount Rainier National Park is now home to wolverines again after a more than 100-year hiatus.
It's a busy time of year for the Texas A&M Forest Service—many highly destructive pests are emerging in their adult form to reproduce and lay eggs. One such pest on the Forest Service's most wanted list is the emerald ash borer.
Craig Shirley sees an opportunity in the trees.
If you've ever seen a bat flying around at sunset, chances are good it was a vesper bat. They're the biggest bat family, made up of 500 species, found on every continent except Antarctica. And most of them look a lot alike—they're little, with fuzzy grayish-brown fur, sort of the sparrows of the bat world. That can make it hard to tell the different species apart. But scientists just discovered...
