The Moon and the Earth From the ISS

From NASA.

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.

Snapshot of Joplin thunderstorm that spawned deadly tornado

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

Dangerous storm system in the southeast USA

From NASA GSFC:

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.
