SMITHSONIAN MAGAZINE - Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have officially identified more than 6,000 planets outside our solar system. “This milestone represents decades of cosmic exploration driven by NASA space telescopes—exploration that has completely...

FORBES - NASA reports that its official tally of extrasolar planets has hit the 6,000 mark. This thirty-year milestone has been in the works since two little known Swiss astronomers, Michel Mayor and Didiez Queloz, first detected 51 Pegasi b. The first of the so-called “hot Jupiters” to be detected, “51 Peg” is a gas...

QUANTA MAGAZINE - enus is arguably the worst place in the solar system. A cloak of carbon dioxide suffocates the planet, subjecting its surface to skull-crushing pressure. Sulfuric acid rains down through the sickly yellow sky but never reaches the lava-licked ground. Venus is so hot — hot enough to melt lead — that the...

POPULAR MECHANICS - For the past several years, dozens of rivers throughout the Arctic watershed have been undergoing a shocking transformation: They’re turning orange. When rivers sport these troubling hues, humans are usually the culprit—whether through mining operations, agricultural runoff, or criminally dumping hazardous materials into waterways. With these rivers mostly tucked away in northern...

DAILY GALAXY - In Alaska’s far north, something strange is happening. Rivers that once ran crystal clear are now turning a rusty orange, and scientists say the shift is permanent. A new study published in The Proceedings of the National Academy of Sciences has uncovered the hidden force behind this transformation, one that is quietly...

DISCOVER MAGAZINE - In the northern Alaskan wilderness, a bizarre symptom of climate change is emerging: The rivers there are turning unnaturally orange. This phenomenon paints a worrisome picture for watersheds all across the Arctic, now faced with toxic metals being released by melting permafrost. A new study published in the Proceedings of the National...

SFGATE - When John McPhee and his ragtag crew first kayaked into the pristine Alaskan wilderness in 1975, they were awestruck. The author, who chronicled his reconnaissance trip in the literary classic “Coming into the Country,” was surrounded by an abundance of untouched flora and fauna. Beneath them, Arctic grayling, chum salmon and Dolly Varden...

LIVE SCIENCE - Imagine a planet twice as wide as Earth, covered in an ocean that smells like sweet cabbage. Every day, a faint red star warms this ocean world and the uncountable masses of hungry, plankton-like creatures that inhabit it. They rise to the surface by the billions, joining together in a living, floating...

US NEWS AND WORLD REPORT - It’s a simple and common prescription for global warming and fire suppression: Plant more trees. But where they’re planted makes a real difference, new research shows. "Our study found more cooling from planting in warm, wet regions, where trees grow year-round," study first author James Gomez , a graduate...

EARTH.COM - Planting more trees cools the planet and can help reduce fires, but the biggest climate returns per tree come from the tropics. That is the core message of new research, which shows that where we plant matters almost as much as how much we plant. The study, led by the University of California...
