A miniature version of the Nile River, seen on Saturn’s moon Titan by the international Cassini mission. The river valley stretches more than 400 km from its ‘headwaters’ to a large sea, and likely contains hydrocarbons. The image was acquired on 26 September 2012, on Cassini’s 87th close flyby of Titan. The river valley crosses Titan’s north polar region and runs into Kraken Mare, one of the three great seas in the high northern latitudes of the moon.

Magnificent CME Erupts on the Sun with Earth to Scale (por NASA Goddard Photo and Video) On August 31, 2012 a long filament of solar material that had been hovering in the sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3. The image above includes an image of Earth to show the size of the CME compared to the size of Earth. Credit: NASA/GSFC/SDO

Observing the Moon (by Science Museum London) Diapositive of photograph taken with the Kew Photoheliograph, 1860–62. This photograph of the Moon was taken by Warren De La Rue using the Kew photoheliograph, the first astronomical instrument with built-in photography. At Kew Observatory, the instrument was used to track changes in the appearance of the Sun and Moon.

planetsci: Desert RATS is a NASA team of engineers, geologists, astronauts, and technicians who go into the deserts of Arizona each summer to simulate missions to the Moon, Mars, and Near Earth Objects, which are small asteroids that are near Earth. This is the team that test drives the new Lunar Electric Rover and very futuristic space habitats. This summer the women and men of Desert RATS are focusing on a mission to a Near Earth Object (NEO), so they are testing space suits, scientific procedures, and a space habitat that would orbit this NEO. Their twitter handle is @DESERT_RATS and they are definitely a team to follow! See what Desert RATS is doing this summer! Read more about the philosophy of Desert RATS (Image Credit: NASA)

In 1859, Richard Carrington observed a large group of sunspots, and two solar flares. The flares’ path is marked A-C and B-D. This was one of the first observations of solar flares, which Carrington suspected were the cause of the disruption on Earth. Credit: Science Museum. (via Stories from the stores)

ISS027-E-036747 (by NASA: 2Explore) 23 May 2011 —- This image of the International Space Station and the docked space shuttle Endeavour, flying at an altitude of approximately 220 miles, was taken by Expedition 27 crew member Paolo Nespoli from the Soyuz TMA-20 following its undocking on May 23, 2011 (USA time). The pictures taken by Nespoli are the first taken of a shuttle docked to the International Space Station from the perspective of a Russian Soyuz spacecraft. Onboard the Soyuz were Russian cosmonaut and Expedition 27 commander Dmitry Kondratyev; Nespoli, a European Space Agency astronaut; and NASA astronaut Cady Coleman. Coleman and Nespoli were both flight engineers. The three landed in Kazakhstan later that day, completing 159 days in space.

Fragile Oasis - Connecting Space and Earth: Learn. Act. Make A Difference. (by FragileOasis)

This extraordinary view of our planet Earth offers a very brief sneak peek #FromSpace of an exciting project we’re working on for @FragileOasis. With our thanks to musician and pioneering advocate for human rights, Peter Gabriel. ”Did you think that your feet had been bound by what gravity brings to the ground? Did you feel you were tricked by the future you picked? Well, come on down …”

ralphewig: Mars Destinations: Ophir Chasma - During its examination of Mars, the Viking 1 spacecraft returned images of Valles Marineris, a huge canyon system 5,000 km, or about 3,106 miles, long, whose connected chasma or valleys may have formed from a combination of erosional collapse and structural activity. This synthetic oblique view shows Ophir Chasma, the northern most one of the connected valleys of Valles Marineris. For scale, the large impact crater in lower right corner is about 18.5 miles, or 30 km, wide. Ophir Chasma is a large west-northwest-trending trough about 62 miles, or 100 km, wide. The Chasma is bordered by high-walled cliffs, most likely faults, that show spur-and-gully morphology and smooth sections. The walls have been dissected by landslides forming reentrants. The volume of the landslide debris is more than 1,000 times greater than that from the May 18, 1980, debris avalanche from Mount St. Helens. Theongitudinal grooves seen in the foreground are thought to be due to differential shear and lateral spreading at high velocities (Image Credit: NASA/JPL/USGS).

14-billion-years-later: The Waters of MarsThe above image shows a basic simulation of what Mars may have looked like two billion years ago. Note the ocean.Evidence has come to light that Mar’s lowlands may have been covered in water. This idea has come about as samples of rock show an abundance of phyllosilicates (a type of mineral) when compared to rock samples from higher elevations. As phyllosilicates are usually found in salt water on Earth so the logical conclusion to make is that parts of Mars were once submerged by oceans. Before you go pack your time machine for a visit to the ancient beaches of Mars it should be noted that this ocean would have been frigid and rimmed by glaciers. When taking a look at the coast line the geological evidence supports this, often showing signs of glacial wear and tear along with deposits of rocks known as moraines.

“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the plant Earth. I didn’t feel like a giant, I felt very, very small.” This is probably my favorite quote. It is from Apollo 11 astronaut Neil Armstrong, who I think is the most poetic of the astronauts.
