Visualizing Fire in IR

Infrared (IR) photography visualizes the landscape in ways hidden from normal human vision. Vegetation health can be easily seen by the intensity of IR color ranges. The extent of Colorado’s recent Waldo Canyon wildfire can now be seen very clearly as black and grey in a new satellite image with living pine forests in dark red and range and grasslands in lighter pink. It doesn’t produce a ‘pretty picture’. Waldo Canyon Wildfire in IR (credit: NASA) WHB

Nighttime Clouds over Tibet

According to NASA, polar clouds can form between nearly 50 miles above the Earth. The sun can illuminate these high clouds even when it is below the horizon, giving them the names of noctilucent or "night-shining" clouds. The International Space Station observed these clouds recently, while flying over the Tibetan Plateau. Like a meditation, Buddha would be pleased by their calm nature.

Zooming into the Milky Way

Much of the Milky Way is shielded from view in visible light by the intervening dust and gas but it can be explored using other forms of electromagnetic radiation. NASA has produced a digital zoom into the galaxy’s center by utilizing images from the Digitized Sky Survey. As the video proceeds, the visible light captured shifts to dust-penetrating infrared and highlights gas clouds discovered falling towards a massive black hole at the galactic center.
