European Space Agency astronaut Alexander Gerst captured this photograph from the International Space Station and tweeted "Words can't describe how it feels flying through an #aurora. I wouldn't even know where to begin..." Not many can share his experience, but photographer Paul Williams captured an aurora while on a flight from London to New York (stills on Flickr). NASA's Science News has an article on Flying Through a Geomagnetic Storm, with information on how auroras are formed, and a bit more on what it's like to fly through them, with an accompanying video (previously).
While on ISS, astronaut Reid Wiseman captured and tweeted a picture that captured night time picture of the Gulf of Thailand, including a vast area of green lights, distinct from the white, yellow and orange lights of adjacent cities. Reid wrote "Bangkok is the bright city. The green lights outside the city? No idea… " but others did know: it was many fishing boats with green fishing light attractors. [more inside]
The Mars Science Laboratory (MSL), aka the Curiosity Rover is something of a robotic geologist, so it makes sense to include the tools of the trade in some form, including a calibration target. For giving a sense of scale with smaller geologic features, pennies are often used for scale, as a common item with a standard dimension. But why is there a 1909 penny on the Rover? That's thanks to Kenneth Edgett, the Mars Hand Lens Imager (MAHLI) principal investigator and an amateur coin collector who appreciates the history of the controversial 1909 V.D.B. Lincoln Cent.
In 1972, Tom Wolfe was assigned to do a piece for Rolling Stone on Apollo 17, NASA's last moon mission (Google book preview). That turned into a four-part series on the astronauts, written in a frantic three weeks. From there, he thought he could quickly expand the piece into a book (Gbp). But that book, on what makes an astronaut, ended up taking a much broader scope and more time. In 1979, The Right Stuff was published, and later was made into a well-regarded 3 hour movie. A few years later, Andrew Chaikin started on a similar path to Wolfe, more broadly documenting the US moon missions in his book, A Man on the Moon. The book was published in 1994, and HBO used it as the basis of a 12-part mini-series that they aired in 1998, titled From the Earth to the Moon. [more inside]
"This video of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, shows the wide range of wavelengths -- invisible to the naked eye -- that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors." And because it's NASA, you can download the video in various formats.
If you've seen images of NASA, you've seen the work of Bill Ingalls, Project Manager and Senior Photographer for NASA Headquarters, who started out as an intern with NASA, and has worked now for the agency for 25 years. You can see a ton of images on the NASA HQ Photos account on Flickr (plus non-NASA photos on his personal Flickr account), and he even has a few short videos on Vimeo. You can read about NASA photographers, including Ingalls, and hear Bill talk about his work with NASA and photography in general in this 365 Days of Astronomy podcast (related: the super moon photo, and Neil deGrasse Tyson's response to the super moon hype).
"The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet." Before we get into terraforming, what about the space between worlds? NASA has a website dedicated to discussions of space settlements (previously), many going back to the 1970s, as seen in the CoEvolution Book on space settlement and the NASA Ames/Stanford 1975 Summer Study. There is also concept art from the 1970s by Don Davis (prev: 1, 2, 3) and Rick Guidice. Escaping from that orbit, there's also a toroidal space colony as imagined in the 1982 book Walt Disney's EPCOT, and more recently, a ton of neat imagery on Bryan Versteeg's Spacehabs website.

NASA's Space Food Hall of Fame
Today's space food has come a long way since the Mercury Program of the early 1960s. When John Glenn first tried apple sauce from a squeeze tube onboard his Friendship 7 spacecraft in 1962, who could have dreamed that later astronauts would be able to choose from such a wide variety of foods?See also: Food in Space: Great Photos of Astronaut Meals, from the Early Space Voyages to Today, on io9.

A moment of adorable: two year old Kayla can't reach the moon, but that doesn't lessen her interest in it. Kayla's dad shared the video on Reddit, where he got a lot of suggestions for books and items to appease her lunacy, and was invited to tour the NASA facilities in California.
First noticed by westerners in 1965, when the Gemini-4 spacecraft flew over northwest Africa (alternate source, with link to uncompressed TIF | in Earth photographs from Gemini III, IV, and V on Archive.org), the Richat Structure in the Sahara desert of west–central Mauritania resembles an impact crater or a circular target (or a possible Atlantis, or Plato's circular city, or maybe an open-pit mine), but is a naturally occurring 40-50 km (25-30 mi) geologic dome that has eroded over time. It's large enough that, when seen in person, the scale of the geography is hard to capture. But it is quite impressive when seen from space (mentioned previously)
The Mix Tape of the Gods: made to be played at 16-2/3 revolutions per second, now traveling 300 million miles per year
August and September 2011 mark 34 years in the journeys of Voyager 1 and 2. The two scientific probes, progeny of the Mariner program, were sent out to survey this solar system and beyond. Voyager 2 completed the Grand Tour in 2009 (excluding Pluto), and Voyager 1 is getting closer to interstellar space (previously). Both scientific probes were sent out in with a time capsule from 1977, golden records secured in plain view on the outside of the Voyager Spacecraft. These greetings from earth (alt links: Coral Cache, Archive.org) were recorded in the form of 116 images, a collection of sounds of this planet, greetings in 55 languages (YT), 27 songs from around the world, and brain waves of Ann Druyan, then recently engaged to Carl Sagan. For all that work, the "Mix Tape of the Gods" almost didn't get sent into space because of some last-minute writing in the run-outs. [more inside]
From Earth to the Solar System (FETTSS) is a collection of images curated by NASA that portray an attempt to understand the origin and evolution of the solar system, by looking to the skies and investigating extreme situations on earth, like high-altitude lakes and an acidic river. [more inside]

"The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity." Dr. Richard Fisher and other sun-gazing scientists recently discussed the upcoming peak in the 11-year sunspot cycle. Due to the ever-increasing humans' reliance on electrical systems, the storm could leave a multi-billion pound damage bill and "potentially devastating" problems for governments. Constant improvements in satellite designs have assisted in bracing for a solar superstorm, an effort that comes in part by studying the impacts records of activity from past peaks in solar storms. System limits are set based on significant solar storm-triggered events in the past, though the largest magnetic storm on record was before the modern understanding of solar events. The solar storm of 1859, also known as The Carrington Event, when "telegraphs ran on electric air," was experienced around the world. [more inside]
Since late January of 2010, the International Space Station was able to access the Internet for personal use, leading to the first tweet from space. The previous tweets were e-mailed to the ground where support personnel posted them to the astronaut's Twitter account. Currently there are 17 active NASA astronauts and 6 internatual'nauts tweeting from on high. If their words aren't enough, they're also posting pictures, primarily from Soichi Noguchi (@Astro_Soichi) and José Hernández (@Astro_Jose, whose socio-political messages were covered previously).

At least three million tons of fishlike creatures could theoretically live and breathe on Europa, according to Professor Richard Greenberg of the University of Arizona in Tucson. Greenberg recently presented his findings to the Division for Planetary Sciences, American Astronomical Society (PDF, Google quick view). Greenberg has written about potential life on Europa before, but his recent calculations suggest that the concentrations of oxygen would be great enough to support not only microorganisms, but also more complex animal-like organisms which have greater oxygen demands.

On October 9th, NASA spacecraft will run into the moon, and on purpose. The Lunar Crater Observation and Sensing Satellite (LCROSS) and its rocket's Centaur upper stage will impact the moon, with the goal of sending some of the (possibly present) ice above the lunar surface. Once out of the eternal shade of the moon's south pole, sunlight will break the ice up into H+ and OH- molecules, which can be detected by the Lunar Reconnaissance Orbiter (LRO). The initial impact site was the crater Cabeus A, but the target was later changed to Cabeus (proper), selected for highest hydrogen concentrations with the greatest level of certainty, and for the high-contrast back drop to detect ejecta and vapor measurements. NASA has provided guides for amateur observations of the impact, a facebook group, and a Twitter feed so you don't miss the moment.
Inspired by its 10th anniversary, the Earth Observatory has pulled together a special series of NASA satellite images documenting how the world has changed. From these images, Wired Science has made 5 videos, presenting convenient time-lapse views of the world changing (mainly) because of human actions. Watch the urbanization of Dubai, specifically the growth of Palm Jumeirah. See the Aral Sea dry up - once the fourth largest lake, down to 10 percent of its original size (marked by the thin black line in the video) by 2007. View the clearing the Amazon, as observed from above the state of Rondônia in western Brazil. Behold the return of Mesopotamia's Wetlands, now in the process of being restored from near total destruction under the regime of Saddam Hussein. Witness the impact of drought on Southern Utah's Lake Powell, where water level dropped from 20 million to 8 million acre-feet from 2000 to 2005.
