"New images, acquired on May 24, 2010 by the Multi-angle Imaging SpectroRadiometer (MISR) instrument aboard NASA's Terra spacecraft, show the encroachment of oil from the former Deepwater Horizon rig into Louisiana's wildlife habitats."

How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.

"View of the solar system showing the locations of all the asteroids starting in 1980, as asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones. The final colour of an asteroids indicates how closely it comes to the inner solar system. Earth Crossers are Red Earth Approachers (Perihelion less than 1.3AU) are Yellow All Others are Green Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You'll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video. As the video moves into the mid 1990's we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you'll see a region of high discovery rates aligned in this manner. At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that's tasked with imaging the entire sky in infrared wavelengths. Currently we have observed over half a million minor planets, and the discovery rates snow no sign that we're running out of undiscovered objects. Orbital elements were taken from the 'astorb.dat' data created by Ted Bowell and associates at http://www.naic.edu/~nolan/astorb.html"

"Anatomists such as Prof Peter Abrahams believe that Leonardo's work was some 300 years ahead of its time, and in some ways superior to what was available in the 19th Century Gray's Anatomy. They say it is only recently with 3D, digital technology and moving images that we have been able to take a decisive step beyond what Leonardo's hand and eye were able to achieve."

"ESA's Planck mission has delivered its first all-sky image. It not only provides new insight into the way stars and galaxies form but also tells us how the Universe itself came to life after the Big Bang."

NASA's Cassini spacecraft is now a nearly a year into its extended mission, called Cassini Equinox (after its initial 4-year mission ended in June, 2008). The spacecraft continues to operate in good health, returning amazing images of Saturn, its ring system and moons, and providing new information and science on a regular basis.

"If you send in a sample of something and a form, they'll run it through their scanning electron microscope for free, and post the images online. Their site explaining the process outlines the 5 steps to make it happen: find a sample, fill out a form, send them to ASPEX, wait for them to scan it (usually about 2 weeks), and look at it online."

"The microscope imaged objects down to just 50 billionths of a metre to yield a never-before-seen, direct glimpse into the "nanoscopic" world. "

The landscapes of other planets have long been the source of fantasies and speculation, but in the last few decades we've finally been able to get a close-up view of the surfaces of alien worlds. NASA's Mars Reconnaissance Orbiter (MRO) has been orbiting Mars since 2006, and on board is the High Resolution Imaging Science Experiment camera, or HiRISE.

"A digital camera that allows photographers to focus their pictures after taking them has gone on sale. Rather than recording a single version of an image, the Lytro captures data about the intensity and direction of all the light entering its lenses."
