The latest pictures to be beamed back from the far reaches of the Solar System show a new mountain range on Pluto and the first close up images of two of the dwarf-planet’s smaller moons.

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.

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.

Dwarf planet Ceres reveals pyramid-shaped mystery


Image of Pyramid taken by NASA’s Spacecraft DAWN. Do you think it is just a simple mountain or Something else.
OK, this is just too much.

First, NASA’s Dawn probe spotted curiously sparkly bright spots on the surface of Ceres, the dwarf planet that lies in the asteroid belt between Mars and Jupiter.
Beats us, the scientists said.

Now, cameras on the tractor-trailer-size spacecraft have captured a baffling structure rising 3 miles above the planet’s cratered surface.

Conveniently, the thing looks an awful lot like a pyramid.”Intriguing,” the NASA scientists said.

To be fair, the agency offered no suggestion that the towering structure is an offering to some long-lost space emperor or home to our new alien overlords.
And, to be even more fair, it’s probably just a really tall mountain in a solar system filled with wondrous and strange natural phenomena.

But the Dawn mission has done nothing but stoke imaginations since the discovery of mysterious bright spots on the surface of the dwarf planet in February and the beginning of the probe’s orbit in March.

Folks have claimed to have spotted giant alien motherships hovering over the planet, bat-winged spaceships parked on its surface and even evidence of alien cities.

But the mystery only deepened with the most recent batch of images showing even more bright spots alongside the largest one, which NASA said looks to stretch some 6 miles.

Many, of course, insist that the spots look for all the world like brightly lit cities twinkling on the shadowed surface of the distant dwarf planet.

I knew it! There’s gambling going on on Ceres! #aliens pic.twitter.com/QP6PB6JFho

Of course, NASA hasn’t traveled down that road. Scientists, they say, still don’t know what the spots are. Maybe ice. Maybe salt.
“But scientists are considering other options, too,” NASA said coyly.
But #itsaliens, right?

Artistic Depiction of Pluto 

The National Space Society put together an incredible video preview of the history-making moment. It has the vibe of a movie trailer, complete with epic narration and stunning visuals, and it perfectly captures why space enthusiasts are so psyched about the New Horizons mission.

The video sweeps you through a timeline of the last half century of space exploration using beautiful images of each planet we’ve explored, starting with Venus in 1962 and ending with Neptune in 1989.

New Horizons will reach Pluto and its moons on July 14, and they will be “the farthest worlds ever to be explored by humankind,” the video says.

So far that the sun appears as a faint dot.

[VIDEO] If some celestial bodies were closer to us


ph1-3_1024

For 25 years now, the Hubble Space Telescope (and many other satellites) has stimulated us with numerous jaw dropping images of space—stretching from the Great Nebula of Orion, to the Whirlpool Galaxy. They all look so huge and comprehensive, you can nearly imagine yourself moving through space, looking directly at them from up close—yet even the closest among them are unfathomably far away (the closest planet is nearly 162 million miles/261 million kilometers from sun, while the closest star is over 4 light-years distant). In a recent video, the Russian Space Agency (Roscosmos, to be exact) visualizes how our sky may look if some of these marvels were in nearer proximity to Earth. Watch the video below:

Mars has Beautiful Auroras Visible with the Naked Eye, NASA Confirms

The stunning light show is similar to the Northern Lights, but a different colour

The Northern Lights are one of Earth’s most spectacular phenomena – with eerie green and red streaks colouring the sky.

It turns out that Mars has a similar light show – visible to the naked eye of anyone on the surface of the Red Planet – but it glows a bright blue.

That’s according to research by planetary scientist Cyril Simon Wedlund from Aalto University.

He and his team carried out an experiment in the lab to simulate the conditions on Mars.

The experiment replicated the Martian atmosphere – made up mostly of carbon dioxide – using a ‘Planeterrella’, a piece of kit that can recreate aurora in the laboratory.

In the case of the Mars experiment, a blue glow formed around the magnetic structures.

They believe that blue is the most prominent color, though red and green may also make an appearance, and that the lights — like ones on Earth — appear several times in a solar cycle, after intense solar activity.

If an astronaut looked to the southern sky from the surface of Mars during one of these flare-ups, the researchers say, he or she would see a sky glowing with blue. Until then, we’ll just have to keep imagining them.

The Auroras are visible in many other planets like Jupiter, Saturn. below are the some photographs of auroras taken by various probes.

See a blue sunset on Mars

The “blue-tinged” sky is caused by fine dust in the atmosphere, according to a statement from Mark Lemmon, a Curiosity team member from Texas A&M University in College Station.

“The colors come from the fact that the very fine dust is the right size so that blue light penetrates the atmosphere slightly more efficiently,” Lemmon said in the statement. “When the blue light scatters off the dust, it stays closer to the direction of the sun than light of other colors does. The rest of the sky is yellow to orange, as yellow and red light scatter all over the sky instead of being absorbed or staying close to the sun.”

Pluto’s five moons captured on camera for first time EVER


ESO-L._Calçada_-_Pluto_(by)

PLUTO’S five moons have been captured on camera for the first time EVER as a NASA probe nears the dwarf planet.

The historic moment was recorded by NASA’s New Horizons probe, which is exploring Pluto and beyond.

Previously the probe has only caught footage of Pluto, which was previously downgraded from its status as a full planet, as well as its largest moon Charon and two of its smallest moons – Hydra and Nix.

However, now, Kerberos and Styx, the dwarf planet’s smallest and faintest moons, are also visible.

Detecting these tiny moons from a distance of more than 55 million miles is amazing, and a credit to the team that built our LORRI long-range camera and John Spencer’s team of moon and ring hunters.

John Spencer, programme scientist of the Southwest Research Institute in Colorado, said: “New Horizons is now on the threshold of discovery. If the spacecraft observes any additional moons as we get closer to Pluto, they will be worlds that no one has seen before.”

NASA said initial viewing appeared to show only four moons visible in the footage, but Charon is also in the images – although it blends into the bright centre of imagery.

Pluto’s four smaller moons were discovered by scientists using the Hubble Space Telescope.

Nix and Hydra were found in 2005, while Kerberos and Styx were discovered more recently in 2011 and 2012 respectively.

The unmanned New Horizons probe will start looking for any more more moons and rings around Pluto this month.

However, astronomers fear previously unseen objects in the dwarf planet’s vicinity may put the spacecraft in jeopardy as it heads toward its closest approach in July – and navigators will be very cautious as it nears.

Alan Stern, New Horizons principal investigator, said: “Detecting these tiny moons from a distance of more than 55 million miles is amazing, and a credit to the team that built our LORRI long-range camera and John Spencer’s team of moon and ring hunters.”

New Horizons was launched towards Pluto in 2006.

Once the probe flies past Pluto and its moons on July 14, the spacecraft will continue flying farther from Earth, investigating other cold bodies past the dwarf planet.

Spectacular Images and Video of India From the International Space Station


OB-VP477_inasa1_G_20121207005704

Pictures and footage of India taken from space show the country by night and day as seen from the International Space Station, including a spectacular lightning storm.

The images were taken by Terry Virts, the commander of the current project, Expedition 43, at the space station and tweeted from his verified account.

A one-year joint mission between space agencies in the United States, Russia and Europe, began on Mar. 11, 2015 and is in its final days. Astronauts are expected to return to Earth on Wednesday.

The six-member crew have been conducting astrophysics research, physical science investigations and technology demonstrations, but no space walks.

Two of the crew, Scott Kelly and Mikhail Korneinko, have spent the entire year in space and have undergone medical studies to help further scientific advancements on Earth. Other astronauts were rotated in at the end of Expedition 42 in December.

The Largest void in universe Discovered


Hubble image of MACS J0717

Astronomers have detected the universe’s largest known cosmological supervoid in the Southern constellation of Eridanus.  Spanning some 1.8 billion light years !!!!!!!

(1 Light Years ~ 9 Trillion Kilometer)

It might be the single largest structure ever in the universe, and the only sign of it is nothing – just empty space 1.8 billion light years across. That’s 18,000 times larger than our entire galaxy.

the team remains mainly baffled as to why such an extensive void — in which the “density of galaxies is much lower than in the known universe” — could have actually arisen.

“This supervoid is certainly rare,” Greg Aldering, a cosmologist at Lawrence Berkeley National Lab in California, told Forbes.  “Underdense by about 30 percent, it’s not completely empty.  But what’s rare is the [spatial] extent of this void itself.”
