This artist's concept illustrates a supermassive black hole with millions to billions times the mass of our sun. Supermassive black holes are enormously dense objects buried at the hearts of galaxies.

An aerial view of the rust-colored Kutuk River in Gates of the Arctic National Park in Alaska. Thawing permafrost is exposing minerals to weathering, increasing the acidity of the water, which releases metals like iron, zinc, and copper.

Why are Alaska’s rivers turning orange?

The planet Venus is dry thanks to water loss to space as atomic hydrogen. In the dominant loss process, an HCO+ ion recombines with an electron, producing speedy hydrogen atoms (orange) that use CO molecules (blue) as a launchpad to escape.

Intercropped tomato (left) compared to monocropped tomatoes (right). Both were planted on the same day, but here we can see that the intercropped tomato plant is larger, bears more fruit, and the tomatoes ripened earlier than its monocropped counterpart.

A mechanical analysis of the distinctive canines of California's saber-toothed cat (Smilodon fatalis) suggests that the baby tooth that preceded each saber stayed in place for years to stabilize the growing permanent saber tooth, perhaps allowing adolescents to learn how to hunt without breaking them.

left image- This rectangular image shows part of the martian surface as if the viewer is looking down and across the landscape, with the irregular, mottled ground appearing in swirled tones of brown and tan. right image- A slice of the martian surface is shown here. A rounded segment of an eroded crater basin is visible to the right. The key features seen across the image are dark spots with tendrils that are eerily reminiscent of spiders. These are visible in large numbers to the left, and scattered irregularly across the rest of the image.
