Mountain pine beetles are about the size of a grain of rice, so of course we can’t see them from space in satellite images. What is visible is what the beetles can do to a pine forest. The washed-out pink color indicates large areas of standing dead or damaged trees.

A closer view of the small cone forming on the floor of crater within fissure 8 today (Sept. 5). By this morning, bits of molten lava emitted from the cone every few seconds had built it up to an estimated height of around 3-4 m (about 10-13 ft).

In preperation for Apollo 15, David Scott and James Irwin trained with a training version of the Lunar Rover known as the "Grover". Apollo 15 was the first mission to bring a rover. This allowed the astronauts to cover a larger distance and explore a larger area.

Landsat-8 nighttime thermal infrared image from April 2017 showing the Tern Lake area. In Yellowstone, temperatures are extremely cold at night in the winter, and most lakes are frozen (dark pixels). West Tern Lake seems to be thawing here - perhaps it receives some thermal waters from nearby hot springs.

Hormones and pharmaceuticals, widely used for treatment of humans, domestic animals, and livestock, have the potential to enter the environment, including groundwater. In 2009, nearly 70% of Americans took at least one prescription drug, and more than half took 2 or more.
