An amazing photo taken by a NASA probe shows Saturn and its large moon Titan shining as pretty crescents in deep space.

The two cosmic bodies were imaged by the Cassini spacecraft, which has been exploring the Saturn system for about 10 years. The image -- released on Monday (Nov. 3) -- was captured as the robotic ship was flying about 1.1 million miles (1.7 million kilometers) from the ringed wonder on Aug. 11, 2013, according to NASA. Some of Saturn's ring plane can even be seen in the black and white image.

"More than just pretty pictures, high-phase observations -- taken looking generally toward the sun, as in this image -- are very powerful scientifically since the way atmospheres and rings transmit sunlight is often diagnostic of compositions and physical states," NASA officials said in an image description. "In this example, Titan's crescent nearly encircles its disk due to the small haze particles high in its atmosphere scattering the incoming light of the distant sun."

Hubble spots massive 'eye in the sky'

It might look like a giant eye in the sky, or something from a science fiction fiction film, but in fact this incredible image reveals just how violent planet formation is.


Captured by the Hubble Space Telescope, it shows the huge dusty debris discs around stars.


Created by collisions between leftover objects from planet formation, were imaged around stars as young as 10 million years old and as mature as more than 1 billion years old in Nasa's images.


The researchers discovered that no two "disks" of material surrounding stars look the same.


“We find that the systems are not simply flat with uniform surfaces,” Schneider said.

Jupiter's ‘one-eyed giant Cyclops’ captured by Hubble

A stunning event captured by NASA’s Hubble Telescope shows a big black eye staring back from Jupiter's Great Red Spot storm. In reality, it is shadow play on a planetary scale.

The image was captured by NASA’s Hubble Space Telescope as it tracked changes in Jupiter’s immense Great Red Spot storm – a storm that has been raging for over 300 years. The black eye is caused by the shadow of the Jovian moon, Ganymede, sweeping across the center of the storm.

“For a moment, Jupiter stared back at Hubble like a one-eyed giant Cyclops,”
a NASA spokesman told the Daily Express.

The Great Red Spot, the largest known vortex in the Solar System at 10,000 miles wide, is a persistent anti-cyclonic storm just south of Jupiter's equator. It has been raging for between 300 and 400 years, blowing winds at 345 miles an hour – speeds that are beyond comparison with even an Earthly Category 5 hurricane, which can only maximize up to 200 miles.

Astronomers are only beginning to fully understand the complexity of Jupiter, a gas giant which has a mass 317 times bigger than Earth. The planet has 62 moons – including four large ones called the Galilean moons, first discovered by Galileo Galilei in 1610. Ganymede is the largest of these moons.
