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.

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.

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.

NASA’s Messenger Spacecraft Crashes into Mercury, Captures Stunning Shots Before Demise

NASA confirmed Thursday afternoon that its Messenger spacecraft collided into Mercury’s surface at more than 8,000 mph, creating a new crater on the planet.

NOTE : MESSENGER (a backronym of MErcury Surface, Space ENvironment, GEochemistry, and Ranging) was a robotic NASA spacecraft which orbited the planet Mercury.MESSENGER became the second mission after Mariner 10’s 1975 flyby to reach Mercury when it made a flyby in January 2008, followed by a second flyby in October 2008, and a third flyby in September 2009, prior to entering Mercury’s orbit in March 2011. It was the first spacecraft to orbit Mercury.

“Going out with a bang as it impacts the surface of Mercury, we are celebrating Messenger as more than a successful mission,” John Grunsfeld, associate administrator for NASA’s Science Mission Directorate said. “The Messenger mission will continue to provide scientists with a bonanza of new results as we begin the next phase of this mission — analyzing the exciting data already in the archives, and unraveling the mysteries of Mercury.”

But before Messenger’s years-long mission came an end, NASA released several new photos of Mercury, as taken by the spacecraft. Some of these photos were composite imagery, combining years of data and photos collected by Messenger, according to CNET.

Here’s one of the incredible false-color images recently published by NASA. The different colors signify variations in mineral composition, topography and other factors on Mercury’s surface.

The mission ended, according to NASA, because the spacecraft’s thrusters have run out of fuel.

China Plans to Build a Solar Power Station in Space


spacestation

China plans to build a huge solar power station 36,000 kilometres above the ground in an attempt to battle smog, cut greenhouse gases and solve energy crisis, much on the lines of an idea first floated in 1941 by fiction writer Isaac Asimov, state media reported today.

If realised, it will surpass the scale of the Apollo project and the International Space Station, and be the largest-ever space project.

The power station would be a super spacecraft on a geosynchronous orbit equipped with huge solar panels. The electricity generated would be converted to microwaves or lasers and transmitted to a collector on Earth, state-run Xinhua news agency reported.

In 1941, American science fiction writer Isaac Asimov had published a short story “Reason”, in which a space station transmits energy collected from the sun using microwave beams.

Wang Xiji, an academician of the Chinese Academy of Sciences and an International Academy of Astronautics member, says Asimov’s fiction has a scientific basis.

After devoting over 50 years to space technology research, Wang, 93, is an advocate for the station: “An economically viable space power station would be really huge, with the total area of the solar panels reaching 5 to 6 sq km.”

That would be equivalent to 12 of Beijing’s Tiananmen Square, the largest public square in the world, or nearly two New York Central Parks. “Maybe people on Earth could see it in the sky at night, like a star,” says Wang.

Wang says the electricity generated from the ground-based solar plants fluctuates with night and day and the weather, but a space generator collects energy 99 per cent of the time.

Space-based solar panels can generate ten times as much electricity as ground-based panels per unit area, says Duan Baoyan, a member of the Chinese Academy of Engineering.

“If we have space solar power technology, hopefully we could solve the energy crisis on Earth,” Duan said.

Wang says whoever obtains the technology first “could occupy the future energy market. So it’s of great strategic significance.”

Countries such as the US and Japan have studied space solar power station. Japan leads the development of wireless power transmission technology. However, many hurdles lie ahead: A commercially viable space power station would weigh 10,000 tons. But few rockets can carry a payload of over 100 tons to low Earth orbit.
