NASA has turned to a process devised in 1864 to help it measure shockwaves created by supersonic aircraft flight. The method, schlieren photography, was invented by German scientist August Toepler to observe the effect of objects moving through transparent media, such as water or air. Read more

Over the last week or so, images from the New Horizons mission have been arriving back at Earth as the probe begins the 16-month task of returning data from its July 14th Pluto flyby. Take a look at the imaging systems responsible for the impressive photos of the dwarf planet. Read more
If $180,000 seems a bit steep for the Canon 1200mm f/5.6L lens B&H is currently offering in its used department, then perhaps this $33,500 NASA 2540mm f/8 lens on eBay sounds a bit more reasonable. That's twice the focal length for a fifth of the price! Read more
In a unique spin on the typical Gigapan panorama we've come to know and love, the company teamed up with NASA on Earth Day this year for something big - an image comprised of self-portraits captured by citizens all over the world. When zoomed out, it resembles an image of Earth from space. The final product has been released, with submissions coming in from every continent. Take a look
More than 50 years after the satellites that captured the first high-res images of the moon plunged to the surface and were destroyed, a Wired article tells the story of a group of people that found the tapes after they ended up in storage in California. Re-engineering the old drives capable of reading the tapes, they've recovered these historically significant images. Learn more
A Russian Soyuz rocket carrying an unlit Olympic torch and three astronauts blasted off to the International Space Station on Thursday ahead of the 2014 Winter Games in Sochi, Russia. On Saturday the ISS crew will take the torch made for the Sochi games on a historic spacewalk. NASA photographer Bill Ingalls was there to document the launch. See gallery
While we're stuck down here on earth, NASA's Curiosity rover is currently trundling around on the surface of Mars, mapping the terrain and analyzing rocks. This week, Curiosity took time out from its busy schedule to snap an arms-length self-portrait, showing the rover in situ, in Gale Crater - 140 million miles from home. The composite image is made up of 55 high-resolution images, taken using its MAHLI camera, which is mounted on the end of a robotic arm. Click through for more details and a link to the full-resolution image.
A number of factors led to the use of 2MP sensors in the main imaging cameras used on NASA's Mars rover, Curiosity, says the project manager responsible for their development. The slow data rates available for broadcasting images back to Earth and the team's familiarity with that family of sensors played a part, says Malin Space Science Systems' Mike Ravine, but the biggest factor was the specifications being fixed as far back as 2004. Multi-shot panoramas will see the cameras deliver high-res images, he explains, but not the 3D movies Hollywood director James Cameron had wanted.
NASA's Curiosity rover vehicle, that landed on Mars on August 6th, has sent back its first color images of the planet's dusty yellow/orange landscape. The image was taken with the camera on the rover's still retracted robotic arm, from behind the dust shield designed to protect the camera. The dust shield will be removed, promising better images, once the dust kicked-up by its landing has settled. This camera, known as MAHLI (Mars Hand Lens Imager), is primarily intended for examining close-up items. Still better images should come once the two Mastcams start sending back images.
