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."

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.

China has completed its first return mission to the moon with the successful re-entry and landing on Earth of an unmanned probe, state media reported.

The probe, Chang’e 5-T1, landed safely in northern China’s Inner Mongolia region, state news agency Xinhua said, citing the Beijing Aerospace Control Centre.

Xinhua said the probe, dubbed “Xiaofei” (little flyer) on social media, took “some incredible pictures” of the Earth and the moon. It is the first trip around the moon and back since US and Russian flights of the 1970s, 40 years ago.

Prior to re-entering the Earth’s atmosphere the unnamed probe had been travelling at 11.2 kilometres per second (25,000 miles per hour), a speed that can generate temperatures of more than 1,500C (2,700F), the news agency reported.

To slow it down scientists let the craft “bounce” off Earth’s atmosphere before re-entering again and landing.

The probe’s mission was to travel to the moon, fly around it and head back to Earth, said the the state science and technology agency, Sastind. The module went 413,000km from Earth at its furthest point.

The mission was launched to test technology to be used in the Chang’e-5, China’s fourth lunar probe, which aims to gather and return samples from the surface in 2017.

The military-run space project has plans for a permanent orbiting station by 2020 and eventually to send a human to the moon.

China currently has a robotic rover, Yutu (Jade Rabbit), on the moon. It landed on 14 December 2013 and completed parts of its mission before grinding to a halt on 25 January 2014 due to equipment failure.

The mission launched on October 23 and is taking an eight-day roundtrip flight around the Moon and is now journeying back to Earth. The mission is a test run for Chang’e-5, China’s fourth lunar probe that aims to gather samples from the Moon’s surface, currently set for 2017. Chang’e 5T1 will return to Earth on October 31.

The test flight orbit had a perigee of 209 kilometers and reached an apogee of about 380,000 kilometers, swinging halfway around the Moon, but did not enter lunar orbit.

NASA rocket to click 1,500 images of Sun in 5 minutes

Follow us on Google+ , Twitter and Facebook




This image provided by NASA shows the sun emitting a significant X3.2-class flare erupting from the lower half of the sun, peaking at 5:40 p.m. EDT on Oct. 24, 2014. NASA's Solar Dynamics Observatory, which watches the sun constantly and captured images of the event.

A sounding rocket fitted with technology to gather 1,500 images of the Sun in flat five minutes is set for launch on Monday.

Capturing five images per second, the Rapid Acquisition Imaging Spectrograph Experiment (RAISE) mission will focus in on the split-second changes that occur near active regions on the Sun.

These are areas of intense and complex magnetic fields that can give birth to giant eruptions on the Sun that shoot energy and particles out in all directions, the U.S. space agency said in a statement.

“Even on a five-minute flight, there are niche areas of science we can focus on well. There are areas of the Sun that need to be examined with the high-cadence observations we can provide,” said Don Hassler, solar scientist at the Southwest Research Institute in Boulder, Colorado.

RAISE will create a kind of data product called a spectrogram which separates the light from the sun into different wavelengths.

“The Sun has been extremely active recently, producing several X-class flares in the past few weeks. The team will aim their instrument at one of these active regions to try to understand better the dynamics that cause these regions to erupt,” Mr. Hassler explained.

The team hopes to see how heat and energy move through such active regions, which, in turn, helps scientist understand what creates the regions and perhaps even what catalyses the sun’s eruptions.

RAISE’s launch time is planned for 2.07 p.m. (EST) from the White Sands Missile Range near Las Cruces, New Mexico.

Cassini sees sunny seas on Titan

This near-infrared, color view from Cassini shows the Sun glinting off of Titan's north polar seas.

As it soared past Saturn’s large moon Titan recently, NASA’s Cassini spacecraft caught a glimpse of bright sunlight reflecting off hydrocarbon seas.

In the past, Cassini had captured separate views of the polar seas and the Sun glinting off them, but this is the first time both have been seen together in the same view.

Also in the image:

– An arrow-shaped complex of bright methane clouds hovers near Titan’s north pole. The clouds could be actively refilling the lakes with rainfall.

– A “bathtub ring,” or bright margin, around Kraken Mare — the sea containing the reflected sunglint — indicates that the sea was larger at some point, but evaporation has decreased its size.

Titan’s seas are mostly liquid methane and ethane. Before Cassini’s arrival at Saturn, scientists suspected that Titan might have bodies of open liquid on its surface. Cassini found only great fields of sand dunes near the equator and lower latitudes but located lakes and seas near the poles, particularly in the north.

The new view shows Titan in infrared light. It was obtained by Cassini’s Visible and Infrared Mapping Spectrometer (VIMS) on August 21.

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.

Amazing picture of Supernova 1987A

Real image SN 1987A located at 1,68,000 light years from earth in Large Magellanic Cloud (Another Galaxy)

you can imagine the power of this supernova by understanding that even it was located at another galaxy it was visible to the naked eye. It was the first supernova that modern astronomers had to observe a SN and to use modern technology in that observation allowing them to gather much more data.

Supernovae are extremwely rare events. About 1 every 200 years is visible and they only last for a month or two.

Hubble captures stunning image of a comet's brush past Mars

NASA has just released this image of comet Siding Spring's close brush past Mars, and it is thrilling.

The image you see above -- a fuzzy white comet hovering above a glowing rust-colored planet -- is actually a composite of several images taken by the Hubble Space Telescope on Saturday and Sunday.

NASA's Hi Res camera aboard a Mars orbiter captured the first images of the nucleus of a comet
There are a few reasons that Hubble could not take a picture like this in a single shot. For one, Mars is 10,000 times brighter than its cometary visitor, making it impossible to see details of Siding Spring and Mars in one exposure.

Also, the two objects were racing past each other during their near-rendezvous on Sunday. At least one of the objects would have been blurry if Hubble tried to take an image of them simultaneously.

The starfield that the two bodies are set against was provided by the Palomar Digital Sky Survey.

Despite being a bit of a cut and paste job, NASA officials say the image accurately illustrates the distance between Siding Spring and Mars at the time of the comet's closest approach.

It also accurately represents the relative sizes of the two bodies.
