NASA’s New Horizons probe has discovered a new, mountain range on bright, heart-shaped region named Tombaugh Region.

These newly-discovered frozen peaks are estimated to be around 5,000ft high – about 600ft taller than Ben Nevis.

The Norgay Mountains discovered by New Horizons on July 15 are much taller, around 11,000ft, roughly the height of The Pyrenees.

The new range is just west of the region within Pluto’s heart called Sputnik Plain and some 68 miles northwest of Norgay Mountains..

New Horizons has also picked up the first images large images of two of Pluto’s smaller moons.
Nix and Hydra – the second and third moons to be discovered – are approximately the same size, but their similarity ends there.

New Horizons’ first colour image of Nix shows a jelly bean shaped satellite which is 26 miles long and 22 miles wide.

Although the overall surface colour of Nix is neutral grey in the image, the newfound region has a distinct red tint. Hints of a bull’s-eye pattern lead scientists to speculate that the reddish region is a crater.

Meanwhile, the sharpest image yet received from New Horizons of Pluto’s satellite Hydra shows that its irregular shape resembles the state of Michigan.

There appear to be at least two large craters, one of which is mostly in shadow. The upper portion looks darker than the rest of Hydra, suggesting a possible difference in surface composition.

After the Moon and Mars, ISRO eyes Venus for next exploration mission


earth-2

After the successful launch of its Mars orbiter, the Indian Space Research Organisation (ISRO) is now viewing Venus as possibly the next planet it can study and explore.

“Besides the Mars-2 mission, we are looking at Venus and even an asteroid for exploration. A project has to be formulated for this before we chart out a proper roadmap for the explorations.  Venus is our neighbour and has many scientific challenges and aspects that need to be studied. Exploring an asteroid is also challenging task,” Dr Kiran Kumar, Isro chairman, told HT.

In 2014, India created history in space when its Mars orbiter slipped into the Red Planet’s orbit in its maiden attempt.

India became the first Asian country to reach Mars and the first in the world to enter the orbit of the planet in its first attempt.

Regarding the Saarc satellite, Dr Kumar said that it would be launched before December 2016. “The activities related to this project are in progress and we should begin building the satellite soon.”

Moving beyond satellite launches and planetary explorations, Isro is also aggressively working with many government departments on optimising the usage of space tools and data.

A national meet on space is likely to be held in Delhi next month, where ministries and departments of the government will give presentations on how they are using space tools in their workings. From civil aviation to railways, tribal affairs to health, postal to agriculture the number of government departments working with Isro has increased to more than 60 in the past few months.

Stunning first hi-definition image of Pluto reveals huge mountains


nh-plutosurface.0

The first ever high-resolution image of Pluto has been beamed back to Earth showing water ice and 11,000ft (3,350 metre) mountains. The mountains likely formed no more than 100 million years ago – mere youngsters relative to the 4.56-billion-year age of the solar system. Nasa says they may still be in the process of building

Like the rest of Pluto, this region would presumably have been pummeled by space debris for billions of years and would have once been heavily cratered – unless recent activity had given the region a facelift, erasing those pockmarks.

‘We now have an isolated small planet that is showing activity after 4.5 billion years,’ said Alan Stern, New Horizons’ principal investigator. ‘It’s going to send a lot of geophysicists back to the drawing board.’

‘This is one of the youngest surfaces we’ve ever seen in the solar system,’ added Jeff Moore of New Horizons’ Geology, Geophysics and Imaging Team (GGI).

This is the first time astronomers have seen a world that is mostly composed of ice that is not orbiting a planet.

Unlike the icy moons of giant planets, Pluto cannot be heated by the gravitational pull of a larger planetary body. Nasa says some other process must be generating the mountainous landscape.

‘This may cause us to rethink what powers geological activity on many other icy worlds,’ says GGI deputy team leader John Spencer of the Southwest Research Institute.

In a Wednesday press conference, scientists also revealed a high-resolution photo of Pluto’s moon Charon, which is covered in cliffs and ridges:

They also released the first-ever photo of Pluto’s tiny moon Hydra, which appears to be covered in water ice:

A new sneak-peak image of Hydra  is the first to reveal its apparent irregular shape and its size, estimated to be about 27 by 20 miles (43 by 33km). The surface shows differences in brightness, which suggests that Hydra’s outer layer is composed manly of water ice .

IN THE IMAGE NASA released of Charon yesterday, astronomers pointed out a collection of vaguely-defined features on the surface of Pluto’s biggest moon. Now, with this latest capture, the New Horizons team has confirmed that the big dent in the icy rock’s surface is in fact an impact crater, surrounded by a couple of deep canyons—one larger than Earth’s Grand Canyon.

Get ready for even more detailed images of Charon and its orbital buddy, Pluto, tomorrow morning when New Horizons makes its closest approach to the system. Geologists will be especially interested to take a closer look at the dark spot on the moon’s northern pole, and the rays of material you can see spraying out from the edges of the crater.

Moon Experiences Quake Just Like Earthquake


8210-earth-and-moon-1920x1080-space-wallpaper

As the earthquake is still an unsolved mystery for the scientists, by adding another, an Indian scientist has discovered that moon also feels tremors and quakes like earth.

The discovery is made by India’s first lunar probe Chandrayaan-1 as the scientist has revealed that when the tectonic plates of moon collide, causes Quakes just like earthquake.

The plates make up the crust and upper surface and when it collide together, it causes moon-quake.

The discovery is noted out by Saumitra Mukherjee, a Professor of Geology and Remote Sensing at the School of Environmental Sciences in Jawaharlal Nehru University and a student of the university Priyadarshini Singh.

The images providing clues to the occurrence of quakes on the Moon, were captured by the Lunar Reconnaissance Orbiter Camera and Narrow Angle camera aboard Chandrayaan-1.

The images depict South Polar region of the Moon and spews clue on the presence of tectonic plates which when move can cause quakes similar to earthquakes, explained study authors.

Launched in 2008, the main aim of the Chandrayaan-1 was to make a 3-dimentsional model of the Moon and mapping of chemical composition on its surface.

The discovery will help the researchers as they may be able to predict quakes on the Moon going ahead, by analyzing tectonic plate movements on the Moon and comparing them with earthquakes.

The icy eyes of Mars


1425859642

One thing all solid bodies in the Solar System share in common is craters. Some worlds, like Mercury or the Moon, are covered in them, having no atmosphere to erode them away. Earth has relatively few; our dynamic atmosphere and water circulation wipes them out after a few millennia. And some icy bodies like Saturn’s moon Enceladus or Jupiter’s Europa only have a few because their surfaces are also constantly changing… on a geologic timescale.

Huge Saltwater Ocean Found on Jupiter Moon Ganymede


15-033i1

Artistic Impression of Ganymede (Largest Moon in the Solar System)

NASA has confirmed that Ganymede, one of the moons orbiting Jupiter, has a saltwater ocean lying below its icy exterior, making it a viable location for life to flourish.

The scientists studying the planet and its outlier moons through the Hubble Telescope shared the news in a statement Thursday, saying that the ocean may bear more liquid than all the water on Earth combined.

Ganymede is an anomaly among moons. It is the largest known moon in our solar system, and the only one that generates its own magnetic field. This attribute produces a phenomenon called aurorae—strips of radiant electrified gas that circle Ganymede’s poles. Because Ganymede is situated so close to its mother planet, any changes to Jupiter’s magnetic field directly affect that of its moon. So when Jupiter’s magnetic field shifts due to the planet’s rotation, Ganymede’s aurorae “rock” back and forth in a sort of cosmic mating dance.

Observing the interplay between the planet and its moon, scientists surmised that an ocean works against Jupiter’s magnetic pull, causing Ganymede to rock less violently than they had anticipated. Once they had observed the planet with the Hubble Telescope, the researchers built computer models that supported speculation that Ganymede has a salty ocean.

Researchers believe the subterranean ocean is 10 times as deep as Earth’s oceans.

Since water is necessary to sustain life, it’s possible that these oceans may confirm the long-suspected presence of life on other planets, or on moons such as Titan and Enceladus.

NASA has speculated since the 1970s that there was water on Ganymede. A 2002 Galileo mission confirmed that the moon had its own magnetic field, but the findings weren’t concrete enough to corroborate suspicion that Ganymede had a vast ocean beneath its outer crust—until now. In a statement, an assistant administrator of NASA’s Science Mission Directorate, John Grunseld, said, “A deep ocean under the icy crust of Ganymede opens up further exciting possibilities for life beyond Earth.”

Europe Wants To Send Humans To The Dark Side Of The Moon

Should we return to the Moon? While Elon Musk, Mars One, and even NASA have their sights set on the Red planet, many think that the Moon is a better option for space exploration .
The European Space Agency (ESA) is one – they just released a new video stating that the Moon is an important and crucial step in mankind’s future.

“In the future, the Moon can become a place where the nations of the world can come together to understand our common origins, to build a common future, and to share a common journey beyond. A place where we can learn to move onwards into the solar system,” ESA explains in the video “Destination: Moon” .

ESA envisions future manned missions to the far side of the Moon – also known as the dark side of the Moon because it never faces the Earth (though it isn’t shrouded in darkness at all). This alien landscape is a rugged terrain, scarred with billions of years worth of impact craters, including one of the largest impact craters in the solar system, the South Pole-Aitken basin.

Scientists think the crater formed around 4 billion years ago. Inside of this 8.1-mile-deep crater, certain parts are shrouded in perpetual, freezing darkness, but at the crater’s rim, shown below, are high, mountainous peaks that bathe in almost-constant sunlight. It’s here, on these lunar mountains that ESA plans to send robots and eventually humans.

By sending future missions to the Moon we will be able to answer questions like:

  • Is there water elsewhere on the Moon?
  • If so, how much?
  • Where did it come from?
  • And what can it teach us about the origins of water and life on Earth?

If the Moon proves to have an abundant store of water under it surface, then future human generations can use the hydrogen and oxygen atoms for rocket fuel.
