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.

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.

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


AuroraOnMars2 (1)

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.

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.

From his perch on the International Space Station, astronaut Terry Virts has been taking some beautiful photos of Earth and space and sharing them on social media.

“Looking down into the eye – by far the widest one I’ve seen,” he tweeted. “It seemed like a black hole from a Sci-Fi movie.”

imrs

According to AccuWeather.com, Super Typhoon Maysak is one of the strongest cyclones in history during the months of January, February and March. It has slammed several Micronesian islands, killing 5 people, and is now on its way to the Philippines. As of early on April 1, Maysak had sustained winds of 240 kph (150 mph), equivalent of a Category 4 hurricane. Gusts as high as 390 kph (180 mph) are possible with this storm.

The typhoon is expected to weaken, but still poses a threat to the islands in its path:

In honor of the Huygens probe’s historic 2005 landing on the surface of Titan (Saturn’s largest satellite, and the only moon in our solar system with a dense atmosphere), NASA has released a movie that recreates, with data collected by Huygens and the Cassini orbiter, a dramatic approach of the moon’s surface from deep space.

The descent on 15 January 2005 lasted a total of two hours, with Huygens landing on a frigid floodplain surrounded by icy cobblestones.

It is the only landing that has ever been performed in the outer solar system to date, and one of only a handful of bodies – the others being Venus, Mars, the moon, two asteroids and most recently a comet – that manmade probes have ever landed on.

On the surface the probe continued to send back data for more than an hour, until its batteries were drained.

Since that historic moment, scientists have pored over volumes of data about Titan sent back to Earth.

New Hubble Telescope Photos Capture One of the Universe’s Most Stunning Formations


In 1995, the Hubble Space Telescope captured what would become one of history’s most enduring images of the universe: The Eagle Nebula’s Pillars of Creation. Now, 20 years later, Hubble has released a collection of brand new, high-definition shots of the iconic formation. 

If you thought the universe was hauntingly beautiful before, wait until you see these.

Behold:

New view of the Pillars of Creation — visible

Comprised of three towers of gas, dust and space matter, structures like this are not altogether uncommon in star-forming regions. But as the Hubble website notes, the Pillars of Creation are some of the most photogenic and mesmerizing examples ever seen.

“The Hubble image of the pillars taken in 1995 is so popular that it has appeared in film and television, on tee-shirts and pillows, and even on postage stamps,” HubbleSite writes.

The telescope used the Wide Field Camera 3 to capture the stunning new images. It sees near-infrared light, visible like and near-ultraviolet radiation, and also has higher resolution and a bigger field of view than the camera that came before it.

This time, Hubble also captured an image taken in infra-red light, which “penetrates much of the obscuring dust and gas and unveils a more unfamiliar view of the pillars,” according to the website. “Here newborn stars, hidden in the visible-light view, can be seen forming within the pillars themselves.”

New view of the Pillars of Creation — infrared

Not everything is happy-go-lucky in Pillars of Creation-land, however. Despite their name, the new shots indicate that the pillars are also being worn down by the very stars they are helping to incubate. “The dust and gas in these pillars is seared by intense radiation from the young stars forming within them, and eroded by strong winds from massive nearby stars,” HubbleSite explains.

Arizona State University’s Paul Scowen, who helped lead Hubble’s first deep dive into the Eagle Nebula, stressed just how incredible our sightings of the Pillars are. “I’m impressed by how transitory these structures are,” he said in a press release. “We have caught these pillars at a very unique and short-lived moment in their evolution.”

Interestingly, environments like the Eagle Nebula and other star-forming regions were instrumental in our own solar system’s development. “What that means is when you look at the environment of the Eagle Nebula or other star-forming regions, you’re looking at exactly the kind of nascent environment that our Sun formed in,” Scowen said.

8 new planets found in ‘Goldilocks zone’, NASA may find Earth’s ‘twin’ very soon


exoplanet-view-from-moon-1920

NASA is closer than ever to finding a twin for the Earth, astronomers said today, announcing the discovery of eight new planets that circle in the habitable zones of their stars.

Two of the eight are the most Earth-like of any known planets found so far outside our solar system, astronomers told the 225th meeting of the American Astronomical Society in Seattle, Washington.

The pair are likely to have hard, rocky surfaces in addition to being an orbiting distance from their stars that is neither too hot nor too cold for water and possibly life to exist, astronomers said. The discovery doubles the number of known planets that are close in size to the Earth and believed to be in the so-called “Goldilocks zone” of the stars they orbit.

“We are now closer than we have ever been to finding a twin for the Earth around another star,” said Fergal Mullally of the Kepler Science Office. “These candidates represent the closest analogs to the Earth’s own system found to date.”

The worlds were found with the help of NASA’s planet-hunting Kepler mission, a space telescope which has scoured more than 150,000 stars for planets beyond our solar system since its launch in 2009. The latest trove of candidate planets found by Kepler and announced today was 554, bringing the total potential planets to 4,175.

Scientists have recently verified the existence of the 1,000th planet found by Kepler.

“Three of the newly validated planets are located in their distant suns’ habitable zone, the range of distances from the host star where liquid water might exist on the surface of an orbiting planet,” NASA said in a statement. “Of the three, two are likely made of rock, like Earth.”

While it is intriguing to consider the possibility of life existing on another planet like ours, the two best candidates are so far away that learning more about them presents a big challenge.
