A small, low-powered camera component made from a “smart glass” material has been created by a group of researchers in Germany with the hope of inspiring the next generation of smartphone cameras.

Study Further:

The micro-iris is an electro-chemical equivalent to the bulky, mechanical blades that are usually found in cameras and has very low power consumption, making it an ideal component for a wide-range of camera-integrated consumer devices.

The device and the first results of its performance have been presented in a study published today, 19 June, in IOP Publishing’s Journal of Optics. Continue reading

Wonderful “yin and yang” photo of Saturn’s moon – Iapetus

NASA has recently added the “yin and yang” appearance of Iapetus. This is really an amazing and unusual image of anything seen in space.

Iapetus:

Iapetus is a moon of Saturn discovered by Cassini in 1671. It has a diameter of 1,471 km (914 miles) and a density only 1.2 times that of liquid water. It has about 75% of ice and about 25% rock. It revolves at 3,561,300 km (2,213,000 miles) from Saturn.

It has been usually called as the yin and yang of the Saturn moons.

About this Picture:

This image of Iapetus was taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 30, 2013, from a distance of about 1.5 million miles (2.5 million kilometers) from the moon. The resolution is about 9 miles (15 kilometers) per pixel. This image has been magnified by a factor of 1.5. In this image, North is up and rotated 30 degrees to the right.

According to NASA, “a runaway migration of ice on the surface, triggered by a preferential initial darkening and consequential warming of the leading hemisphere of the moon by infalling debris from the outer moon Phoebe” is probably the reason of this appearance of Iapetus.

Now Mercury has a crater named after English musician/singer/songwriter John Lennon (1940-1980), i.e. Lennon crater that has recently been named.

This crater is about 95 km (59 mi.) in diameter. The resolution of the image is showing 165 meters/pixel. Continue reading

NASA has recently released new images of the planet Saturn and its moons. These images have been obtained from the Cassini spacecraft earlier this year.

Saturn looks like an ornament in one image having a jet stream and hurricane-like storm at its north pole. Titan, Saturn’s largest moon, has also been imaged with the Cassini. Image shows the hazy atmosphere and hydrocarbon lakes on the moon. On the other hand, Enceladus, an icy Saturn moon looks like a white snowball. Continue reading
