Color composite of Titan, from Rev171 highlighting its methane content. The reddish part of this image corresponds to more haze (the north polar hood). The detached haze layer seen in this recent image by Cassini. This observation of a gibbous-phase Titan was part of the "Titan Monitoring Campaign" (TMC).

These images were taken on September 04, 2012 and received on Earth September 07, 2012. The camera was pointing toward TITAN at approximately 1,275,131 miles (2,052,124 kilometers) away, and the images were taken using the CL1, CL2, BL1, MT1 and CB3 filters.

The International Space Station has tracked Hurricane Matthew all week, providing images and video from low Earth orbit as the storm hit the Caribbean Sea and made its way towards Florida. In this photograph taken by Expedition 49 Flight Engineer Kate Rubins on Oct. 4, 2016, at 21:05 GMT, the hurricane's clouds extend across the frame and the space station's solar arrays are visible at the upper-right corner of the image. As the hurricane strengthens and approaches the Florida coast, NASA and NOAA satellites continue to provide forecasters and scientists valuable data on the development and changes in the storm.

ENGLISH: Frame of the time-lapse video "A 2dF night at the Anglo-Australian Telescope". Startrails over the Anglo-Australian Telescope on 23 Sep 2011. The colours of the stars are clearly seen in this image, which stacks 1h 6min of observing time.

ESPAÑOL: Fotograma del timelapse "A 2dF night at the Anglo-Australian Telescope". Trazas estelares sobre el Telescopio Anglo-Australiano el 23 de septiembre de 2011. Esta imagen apila 132 imágenes de 30 segundos (1 hora 6 minutos) de observación. Las estrellas en la parte superior de la pantalla pertenecen al Hemisferio Sur Celeste, mientras que las estrellas en la parte inferior corresponden al Hemisferio Norte Celeste Los colores de las estrellas son mucho más evidentes en este tipo de secuencias. La Vía Láctea aparece como un débil rasgo rojizo a la izquierda del AAT. En esta imagen, que tiene más resolución que lo que se ve en el video, también aparece el final de la rama de un árbol (arriba izquierda) iluminado por una linterna roja.

Flying over the Philippine Sea, an astronaut looked toward the horizon from the International Space Station and shot this photograph of three-dimensional clouds, the thin blue envelope of the atmosphere, and the blackness of space. The late afternoon sunlight brightens a broad swath of the sea surface on the right side of the image. In the distance, a wide layer of clouds mostly obscures the northern Philippine islands (top right).

Looking toward the sun to capture an image is a special technique used by astronauts to accentuate the three dimensions of landscapes and cloudscapes through the use of shadows. Two large thunderclouds rise next to one another (lower right). These clouds have long tails, also known as anvils, that stretch nearly 100 kilometers to the south. Anvils form when thunderstorm clouds rise high into the atmosphere and reach a “capping layer” thousands of meters (tens of thousands of feet) above sea level. Capping layers stop the upward growth of a cloud, deflecting air currents horizontally to form anvils.

Astronaut photograph ISS048-E-10018 was acquired on June 25, 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 Cassini spacecraft snapped this view in an infrared filter to peer through Titan’s thick atmosphere and image its surface.

Atmospheric features in this view:
Titan's north polar hood is just visible in this view.

Surface features:
The darker areas are vast hydrocarbon sand dunes. You can see many other features including craters, maculae (dark spots), faculae (bright spots), and large ringed features.

This image was taken by Cassini's camera system, the Imaging Science Subsystem (ISS) on April 4, 2016 and received on Earth April 5, 2016. The camera was pointing toward TITAN, and the image was taken using an infrared filter.

These U-shaped ridges along this crater’s interior wall provide clues to an ice-rich past. The curved, scalloped ridges, called moraines, are made up of rocks that the glacier collected as it moved downslope.

Even after the ice disappears, the glacial moraines remain, marking the furthest extent (or end) of the glacier. The parallel linear ridges on the wall may mark past levels of the glacier. Although glaciers move slowly, ice is a very powerful way to modify the surface of a planet.

Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 Angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.

In this view, a vortex swirls around Titan's south pole while layers of haze surround the moon.

This is a false color view of Titan colorized to approximate true color. Titan's south polar vortex can be seen in the lower left of this image.

More information about Titan's vortex can be found here: What's that spot on Titan's South Pole?

This composite is made of images that were taken by Cassini's camera system, the Imaging Science Subsystem (ISS) on June 26, 2012 and received on Earth June 27, 2012. The camera was pointing toward TITAN at approximately 300,176 miles (483,087 kilometers) away, and the images were taken using methane band, continuum band and ultraviolet filters.

After the sampling operations of conglomerates at Fall River Pass were completed, the Perseverance Rover started moving West through very Rocky terrain towards a new Science objective, called the Margin Carbonate Unit.
This area is 400m west of the rover an not yet visible from the current location. Scientists hope to learn more about the past environment on Mars from the rocks there and whether it facilitated life.
This panorama was assembled from Navcam images taken on the afternoon on Sol 904. I also added sky images from sol 889. These images were taken at a different time of day, but at the same sun elevation, so they could be combined.
