An astronaut aboard the International Space Station (ISS) took this photograph while flying over Asia and looking southeast toward the horizon. Astronauts have unique opportunities to photograph Earth from various angles while orbiting in the thermosphere layer of Earth’s upper atmosphere.
In the foreground we see Lake Balkhash in Kazakhstan. The lake’s main sources of water come from the Ili and Karatal (also Qaratal) Rivers. The Ili River Delta is a megafan deposit that forms a conical shape along the shores of Lake Balkhash. The cloud-covered Tian Shan Mountains of northwest China feed snowmelt waters to the Ili River and Lake Balkhash.
Set against the darkness of space, the Moon appears to hover over the landscape. Astronauts on the ISS see the same lunar phases as we do on the ground. The steep color gradient in the upper third of the photo marks the edge of Earth’s atmosphere and is known as the limb. The Moon does not have a gradually darkening limb because it lacks an atmosphere; the lunar limb appears simply as a sharp demarcation between the surface and the darkness of space.
Astronaut photograph ISS048-E-2035 was acquired on June 19, 2016, with a Nikon D4 digital camera using a 116 millimeter lens, and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 48 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Caption by Andrea Meado, Jacobs Technology, JETS Contract at NASA-JSC.
This satellite image with overlay shows the moment that the storm reached maximum intensity.
The city of Joplin, MO is reeling after a powerful tornado spun through a densely populated part of town on Sunday May 22nd. This image, from GOES East satellite at 2345UTC, shows the storm system moments before spawning the tornado, estimated to have struck shortly before 6:00 pm CST. Many houses, school buildings and the St. John Medical Center sustained major damage.
Classic Comma Head Extratropical Cyclone over the Eastern U.S.
This extratropical cyclone shows a classic comma shaped cloud system usually associated with dangerous winter weather. In this picture we are seeing the cyclone in its mature, or occluded, stage, when the storm begins to lose its ability to deepen. Soon this storm will begin to shear into a persistent, cold-core low. This image was taken by GOES East at 1845Z on April 12, 2011. Source: NOAA/NASA GOES Project
A low pressure area currently over northern Illinois and southern Wisconsin has created conditions that call for a forecast of severe weather in the eastern third of the U.S. today and one area is even labeled “high risk.” The GOES-13 Satellite captured a visible image of the system today as daytime heating was boiling up strong and severe thunderstorms.

Infrared imagery from the GOES-East satellite shows a line of severe storms moving across the Eastern U.S. The National Weather Service has issued severe thunderstorm watches and warnings for many parts of New York through Virginia, flash flood advisories throughout much of the South, and gale warnings along Lake Superior. This colorized infrared image was taken on April 26, 2011 at 1815z.
Viewed from space, the most striking feature of our planet is the water. In both liquid and frozen form, it covers 75% of the Earth’s surface. It fills the sky with clouds. Water is practically everywhere on Earth, from inside the planet’s rocky crust to inside the cells of the human body. Continue reading Terra, the water planet, our home→
