NASA theorizes how lake depressions on Titan were formed

Titan is one of Saturn's moons and one of the most interesting things about the moon is that it has lots of seas and lakes that are filled with liquid hydrocarbons. One thing that puzzles NASA scientists about the lakes of hydrocarbons on the surface of the moon is what process exactly creates the depression that the hydrocarbon lakes fill. Some of the depressions aren't filled with liquids.

NASA collects all of its space photos into single image gallery

NASA collects all of its space photos into single image gallery

If your hobbies include browsing various space photos, NASA has just made your day. The agency has unveiled a huge photo library that features every photo from past to present, totaling up to over 138,000 images. Sources include photos taken by the Hubble, JPL (Jet Propulsion Lab), and missions including Apollo. Called the NASA Images collection, the gallery was built by Luna Imaging, and combines over 70 previous galleries into a single, searchable database.

NASA’s Cassini spacecraft returns incredible pics of Dione

NASA’s Cassini spacecraft returns incredible pics of Dione

NASA's spacecraft Cassini has returned high-resolution and quite impressive images of Dione, Saturn's moon. The spacecraft took the images during its most recent flyby of the moon (earlier this week), and NASA has made them available as unprocessed RAW images, a more particular selection of which can be found at the CICLOPS website. This isn't the last we'll be getting images of Dione, though, as another flyby will be happening in a couple months with more imaging being planned.

Philae speaks again: Comet probe “doing very well”

Philae speaks again: Comet probe “doing very well”

The Philae lander has resumed communications with Earth for the second time since the surprise message last Sunday that proved the spacecraft was still functional. Two signals were successfully received today, the European Space Agency (ESA) said, each lasting two minutes and containing 185 packets of data. Although there's no scientific research in among those bytes, Philae has sent back vital information about just how well the distant probe is doing on its unusual comet ride.

How Silver Ants use hair like NASA’s new heat shield tech

How Silver Ants use hair like NASA’s new heat shield tech

The Saharan Silver Ant is discovered to dissipate heat using shiny silver hairs covering its entire body. Norman Nan Shi, assistant professor of applied physics at Columbia Engineering, has shown that the hairs of the Saharan Silver Ant act like heat shields, not entirely unlike NASA's space suit materials being developed for use by firefighters here on Earth. These ants live in an environment which can get extremely hot, up to 70°C (158°F). To make due when they need to forage for food, they've developed a rather intense bit of natural resistance, making them as shiny as they are cool.

NASA’s Europa mission passes first major review

NASA’s Europa mission passes first major review

NASA is hot to explore Europa, which is one of the moons orbiting Jupiter. The reason that Europa is such an interesting place to NASA is because it is believed to be one of the most likely places to find life outside of Earth. NASA has a mission concept for investigating Europa and that plan has successfully passed its first major review by the space agency.

Black Hole measured by ALMA: visualizing 140 million suns

Black Hole measured by ALMA: visualizing 140 million suns

Researchers at SOKENDAI measure the supermassive black hole inside the barred spiral galaxy NGC 1097 with ALMA. Inside they've found a mass equivalent to 140 million times our own Sun. Two bits of information are stunning about this particular bit of research. First, that they were able to measure a black hole with the tools they've got onhand. Second, that they were able to calculate the results of this study in just under two hours, leading the way to greater studies inside the capacities of ALMA.

NASA high-temp materials for spacecraft may help save firefighters

NASA high-temp materials for spacecraft may help save firefighters

NASA research and technology often spills over into the civilian world as time goes by. Over the years, we have seen a number of products become very popular in the civilian world that originated with NASA such as hook and loop closure material and other stuff. NASA is working on new technology to protect spacecraft during the fiery reentry to Earth by layering different heat resistant materials.

NASA spacecraft spots dust cloud around the moon

NASA spacecraft spots dust cloud around the moon

The moon — meaning our moon — has a cloud of dust around it described as lopsided, and it is confounding researchers. Apollo 15 and 17 crews had observed a glow around the moon that was thought to be due to dust, but this latest dust observation — which is thanks to NASA’s LADEE — is said to be different. The Lunar Atmosphere and Dust Environment Explorer (LADEE) is a spacecraft with a dedicated “dust instrument”, and it made its observations while on a low-altitude orbit mission.

UrtheCast reveals UHD full color videos of cities as seen from space

UrtheCast reveals UHD full color videos of cities as seen from space

UrtheCast, which has been working steadily on getting video of our planet as seen from the International Space Station, has introduced the first videos in full color of Earth as seen from space -- that, at least, the average person and businesses have access to. The videos come from a pair of cameras that have been set up on the ISS, and there are three cities that have been recorded in full color at high definition with them: Boston, USA, London, UK, and Barcelona, Spain.
