Newly-discovered frozen peaks on Pluto are taller than Ben Nevis while images of Nix reveal an unusual red spot

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.

New Nasa camera provides an ‘EPIC’ view of Earth


2AB3935E00000578-0-image-m-3_1437412825315

This is what Earth looks like from a million miles away.

The stunning image, which focuses on America, was taken by the Deep Space Climate Observatory (DSCOVR) and is the satellite’s first view of the entire sunlit side of our planet.

It was presented to the White House today, prompting a tweet from President Barack Obama describing it as: ‘A beautiful reminder that we need to protect the only planet we have.’

The blue marble was captured by the Earth Polychromatic Imaging Camera (Epic) and created by combining three separate images to show the Earth in incredible detail.

The camera takes a series of 10 images using different narrowband filters – from ultraviolet to near infrared.

‘This first DSCOVR image of our planet demonstrates the unique and important benefits of Earth observation from space,’ said Nasa Administrator Charlie Bolden.

DSCOVR orbits the sun at a location called the Lagrange point 1, or L1, It’s from that unique vantage point that the Epic instrument is acquiring science quality images of the entire sunlit face of Earth. Data from Epic will be used to measure ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth

Astronomers Find Rare 5-Star System

An illustration of two contacting stars — part of the newly discovered bizarre five-star system.

Scientists have discovered an absolutely bizarre star system about 250 light years away, in the constellation Ursa Major.

The system (officially known as 1SWASP J093010.78+533859.5) features five stars that are all gravitationally bound together. Two orbit each other in what’s called a contact eclipsing binary, meaning they’re so close together that they actually share an atmosphere, with gases flowing between them.

Another two stars also orbit each other, but at a much greater distance — about 1.8 million miles, which is more than twice the diameter of the sun. Another star hangs out near that pair, but doesn’t appear to orbit them.

Systems that include five stars gravitationally bound together are rare, though not unprecedented (astronomers have actually found systems that include as many as six stars). But this is the first one ever found that includes multiple pairs of stars orbiting each other.

The discoverers of the strange system — a team of astronomers from Open University in the UK and elsewhere — presented all these discoveries in a new paper published in the journal Astronomy & Astrophysics. Thanks to George Dvorsky at io9 for bringing it to our attention.

The New Horizons Pluto mission is a big deal. Here are Some reasons why


SOURCE : vox.com 

NASA’s New Horizons spacecraft is about to show us an alien world for the first time. At precisely 7:49 am ET on Tuesday, the probe will become the first spacecraft to fly by Pluto.

New Horizons has been en route for nine years, traveling more than 3 billion miles. The flyby will be over in a matter of minutes, as the probe frantically takes hundreds of photos and collects data on Pluto’s atmosphere, geology, and moons. All this data will be enormously valuable to scientists as they seek to understand our solar system and how it formed billions of years ago.

More than anything, this mission is about broadening our horizons — taking in just a little bit more of the impossibly vast universe we live in.

1) We’ve never seen Pluto before

Pluto feels familiar. It’s easy to imagine the small, frigid rock, millions of miles from the sun and covered in ice.

But what you’re picturing in your head when you think about Pluto is probably an artist’s illustration. Until very recently, we didn’t even know exactly what color it was — and the best photos we had of Pluto looked like this:

pluto-hubble

New Horizons is going to change that in a very big way. Already, as it’s closed in on Pluto, it’s given us way better photos than ever before:

The high-resolution photos to come will give us detailed topographical maps, just like those provided by the satellites that orbit Earth. They could reveal mountains, ice caps, volcanoes, or even an ocean of liquid water under the ice. “Who knows what kind of bizarre things we’ll find up close?” Stern said.

2) This mission will remind you how vast space really is

Pale-Blue-Dot

Earth, as seen by the Voyager spacecraft, from more than 4 billion miles away.

We spend our entire lives on the surface of Earth — so it’s hard to really grasp how far away Pluto truly is from us.

But as an analogy, think of Earth as a basketball. By comparison, Pluto would be a little larger than a golf ball. But if you wanted to keep the scale constant, you’d have to put that golf ball incredibly far away: 50 to 80 miles (depending on its location in orbit). This mission, like many activities in space, is a good reminder of how vast our corner of the universe is — and how absurdly tiny our entire earthly realm of experience is by comparison.

And it’s not just the size of space that boggles the mind. It’s also the timescale on which everything occurs. Pluto takes 248 Earth years to orbit the sun. To put it another way, the entirety of US history has occurred during a single Plutonian orbit.

3) We won’t get many more missions like this for a while

europa

There’s a mission to Europa planned, but it won’t reach the moon for a decade or more.

The past few decades have been filled with all sorts of fascinating missions to the planets, moons, asteroids, and comets of our solar system — uncrewed probes sent every few years, run by trained scientists, and supported by government funding.

But the sad truth is that this era is largely drawing to a close. As David W. Brown writes in an article on the dark future of American space exploration, “There is nothing budgeted in the pipeline to take its place. Yesterday invested in today. But we are not investing in tomorrow.”

This is the result of cutbacks to NASA’s planetary exploration budget. The OSIRIS-REx probe will launch next year, to travel to an asteroid and bring back a sample, but it won’t return until 2023. Meanwhile, a mission to Jupiter’s moon Europa is in the works, but it likely won’t be launched until 2025 at the earliest, and wouldn’t reach Europa until the 2030s.

In other words: Enjoy this brief flyby. It’s going to be a while before any NASA probe visits a new world.

4)This is a staggering technological achievement

t’s hard to appreciate just how difficult it is to send a spacecraft to Pluto. But think of it this way: because it’s so incredibly far away, it took New Horizons nine years to cover the 3-billion-mile trip there — which means the craft is using decade-old technology, traveling a route that was calculated years ago.

Screen_Shot_2015-07-09_at_9.53.45_AM.0

New Horizons’ trajectory through the solar system.

Despite this, NASA engineers managed to get the tiny probe — about the size and shape of a grand piano — to an incredibly precise spot in space, using Jupiter’s gravity as a slingshot to accelerate it outward and a few thruster burns over the years to keep the probe on track.

Along the way, they had to worry about potentially damaging debris nearby Pluto — as well as a scary software glitch this past weekend, which was, thankfully, resolved. Now New Horizons is going to fly within 7,750 miles of Pluto, coming closer than its moons.

Because New Horizons is traveling at such a high speed (about 31,000 miles per hour) and can’t slow down, the flyby will be over in a matter of minutes — fording it to collect all its data in a tiny window of time.

And receiving all that data is another huge challenge. Because New Horizons is so far away, it takes about 4.5 hours for any data it sends back to reach Earth. And the signal is so faint that NASA has to use 200-foot-wide radio dishes (one each in Australia, California, and Spain) to pick it up. This means an extremely low rate of data transmission: about 1 kilobit per second, more than 50 times slower than a 56k modem from the ’90s. It takes more than 42 minutes for New Horizons to fully transmit an image that’s 1024 pixels wide.

If you haven’t been paying attention so far, now’s the time to start. This is a really big deal.

CHARON’S IMPACT CRATER EMERGES IN LATEST NEW HORIZONS SHOT


nh-7-13-15_charon_image_nasa-jhuapl-swri

NASA/JHUAPL/SWRI

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.

NASA to Send Microsoft’s Virtual Reality Headset to International Space Station


NASA is sending Microsoft’s virtual reality headset to the International Space Station (ISS) to beam back to Earth what astronauts see in space.

NASA and Microsoft are teaming up to develop Sidekick, a new project using commercial technology to empower astronauts aboard the ISS.

Sidekick uses Microsoft HoloLens to provide virtual aid to astronauts working off the Earth.

A pair of the devices is scheduled to launch on SpaceX’s seventh commercial resupply mission to the station on June 28.

“HoloLens and other virtual and mixed reality devices are cutting edge technologies that could help drive future exploration and provide new capabilities to the men and women conducting critical science on the International Space Station,” said Sam Scimemi, director of the ISS programme at NASA Headquarters in Washington.

“This new technology could also empower future explorers requiring greater autonomy on the journey to Mars,” said Mr Scimemi.

The goal of Sidekick is to enable station crews with assistance when and where they need it. This new capability could reduce crew training requirements and increase the efficiency at which astronauts can work in space.

“Sidekick is a prime example of an application for which we envisioned HoloLens being used – unlocking new potential for astronauts and giving us all a new perspective on what is possible with holographic computing,” said Alex Kipman, technical fellow, Windows and Devices Group at Microsoft.

NASA and Microsoft engineers tested Project Sidekick and the Microsoft HoloLens aboard NASA’s Weightless Wonder C9 jet to ensure they function as expected in free-fall in advance of their delivery to the microgravity environment of the space station.

Sidekick has two modes of operation. The first is “Remote Expert Mode,” which uses Skype to allow a ground operator to see what a crew member sees, provide real-time guidance, and draw annotations into the crew member’s environment to coach him or her through a task.

Until now, crew members have relied on written and voice instructions when performing complex repair tasks or experiments.

The second mode is “Procedure Mode,” which augments standalone procedures with animated holographic illustrations displayed on top of the objects with which the crew is interacting.

This capability could lessen the amount of training that future crews will require and could be an invaluable resource for missions deep into our solar system, where communication delays complicate difficult operations.

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.

 Another Image of Ceres showing Strange mysterious lights. Image taken by NASA’s DAWN spacecraft.
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

 
— Chris Reher (@Chris_Reher) June 13, 2015
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.

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.

[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:
