But what about this far-out notion: Could there be aliens on the moon watching humankind from a relatively close distance?Thats a meaty question that brings out emotional responses from anyone you ask.For decades, researchers have claimed that strange objects have been seen on or above the moon — things that shouldnt be there. From mysterious pyramid shapes to unusual moving lights to tall towerlike objects to geometrically oriented buildings and huge glasslike dome structures, stories and pictures abound claiming that Earths next-door neighbor is loaded with extraterrestrial artifacts.Getty ImagesAre there now or have there ever been aliens on the moon? The debate continues.”What NASA did not tell the American people is that it discovered the remains of an ancient lunar civilization, and to this day, that data and those artifacts have been withheld from the American people,” claims Richard C. Hoagland, founder of The Enterprise Mission, an extensive private space research analysis website.Hoagland, a former NASA consultant and curator of astronomy and space science at the Springfield Science Museum in Springfield, Mass., was also a consultant to CBS News during the Apollo moon missions. He has spent decades looking into what he asserts is the truth about the numerous unmanned spacecraft missions as well as the manned Apollo voyages to the moon 40 years ago.”The orbital photographs show us the scale of ancient ruins on the m

Scientists have been searching for water on the Moon for years
Contrary to recent reports about water content in lunar rocks, the Moon may be quite dry, say scientists.
A study by US researchers, published in Science, analysed chlorine isotopes of the much-studied samples, brought to Earth by the Apollo space missions.
They added that there was no or very little hydrogen in the magma ocean during the Moon’s formation.
And that would mean the Earth’s natural satellite may have always been too dry to host life.
Zachary Sharp from the University of New Mexico led the study.
According to one of the theories of the Moon’s formation, a Mars-size object collided with the young Earth billions of years ago. As a result, our planet’s satellite was formed.
It crystallised and cooled shortly thereafter, about 4.5 billion years ago.
Before it cooled, there was a so-called magma ocean on the Moon’s surface – molten rocks, capable of retaining high quantities of water.
"As the Earth has cooled and crystallised, there were gases from volcanoes coming to the surface and the steam from them has probably formed the majority of the oceans. Our oceans came from water dissolved in rocks," said Dr Sharp.

"The same thing may have happened on the Moon, except that the Moon is too small; gravity is too weak to retain this water so it would have been lost to space."
In their quest for water on our planet’s satellite, researchers have had to rely on the analysis of lunar rocks that US Apollo space missions brought to Earth in the late 1960s and early 1970s.
The main goal has always been to find hints that the rocks were hydrated when they cooled, said the scientist.
Dr Sharp and his colleagues decided to analyse an extremely hydrophilic element of the Apollo samples – chlorine.
It is a very sensitive indicator of hydrogen levels – and where there is hydrogen, there is water.
"Chlorine loves water. And we wanted to see if the ratio of chlorine 37 to chlorine 35 was similar to Earth’s or not," he said.
"We very absolutely shocked when we found that not only it’s not similar, but unlike the Earth where every sample is essentially the same, here we’re getting these enormous differences. They were so big that we thought at first that we had maybe some analytical errors, that we were doing something wrong."
He explained that on Earth, the chlorine 37 to chlorine 35 ratio is pretty much constant – it varies only by about 0.1%.
Scientists say that at first, there was a "magma ocean" on the Moon
But the team found that on the Moon it was about 25 times that of the terrestrial chlorine isotope ratio.
Dr Sharp said that if lunar rocks had initial hydrogen contents anywhere close to those of terrestrial rocks, the chlorine isotope ratios would not have so much scatter.
"It was just unheard of, it was inexplicable. We went back, re-analysed things and checked that everything was OK.
"We then came up with the idea that in order for this to happen, to have these huge variations, the [Moon] must have been dry when these basalts crystallised from magma. The lavas that must have poured out onto the surface had no water dissolved in them."
When geologists first studied the Apollo samples, they found no evidence of water and declared the Moon dry.
The only way for scientists to look for water on the Moon is by analysing lunar rocks
But over the last few years, researchers re-examined the rocks and suggested otherwise.
Earlier in 2010, a US-led team led by Francis McCubbin looked at the mineral apatite in lunar samples and discovered that there was at least 100 times more water in the Moon’s minerals than previously believed.
Dr Sharp said that he realised the results of his team’s research clashed with previous studies.
A radar experiment aboard India’s Chandrayaan-1 lunar spacecraft also found thick deposits of water-ice near the Moon’s north pole. But these deposits probably came from comets that slammed into the Moon’s surface, said Dr Sharp.

‘Rain of luminous beams’ appears in the sky of Xiamen Huandao Road
Dozens of vertical luminous beams appeared in the night sky of Xiamen about 11:30pm last Friday, reports Southeast Express.
The singular sight, which lasted for nearly one hour, was first discovered by Mr. Wang’s friend, a resident in Huangcuo, near Xiamen’s famous Huandao Road.
According to Mr. Wang, his friend first saw several luminous beams in the sky and then told them to go outside and take a look. They were stunned by the sight before their eyes.
“At first, there were only five of them, hanging very low in the sky, but after a short while, the number increased to about 50, and they were higher and higher, just like a stave hanging in the sky,” Mr. Wang said.
The Xiamen meteorological observatory said no such astronomical phenomenon was monitored by the observatory. “But it was not a meteor shower,” a staff member said.

Japan plans to build robot moon base by 2020

(PhysOrg.com) — Believing that a moon base is essential for exploration of the solar system, Japan has recently announced plans to send humanoid robots to the moon to construct a robot lunar base. As part of the $2.2 billion project, the robots will begin surveying the moon around 2015, and then build the unmanned base near the moon’s South Pole by 2020.
A Japanese government panel chaired by Katsuhiko Shirai, President of Waseda University, has developed a rough outline of the project. First, the robots, weighing about 660 pounds each, will begin by surveying the moon, taking images of the surface, collecting rocks, and returning the rocks to Earth via rocket for seismographic research. Later, robots will be sent to the moon to construct the lunar base for themselves.
According to the government panel, the robots and the unmanned moon base will be powered by solar panels. The robots will be controlled from Earth, but will also have a high degree of autonomy that enables them to operate on their own to perform certain tasks. Ultimately, the base could serve as a starting point for future robot colonizers, and even human colonizers.
