  • Video: GRAIL to film dark side of Moon for first time

    The proof that Aliens do not live on the Moon was revealed a few days ago when one of NASA’s twin probes GRAIL recorded a video footage with the dark side of the Moon, for the first time.

    The Moon orbits around Earth facing only one hemisphere. The other hemisphere, which receives the same amount of light, has been poetically called the dark side of the Moon. Apollo 16 mission took photos of Moon’s hidden face, but until recently none has recorded ​​a video. One of NASA’s twin Gravity Recovery And Interior Laboratory (GRAIL) spacecrafts called “Ebb” finally made ​​it on January 19, 2012 using its onboard MoonKAM camera and NASA released a video fragment. From Grail’s imagery it can be seen that the far side of the Moon is covered with craters. Various theories that alien civilizations are living on the moon were circulating on the Internet, but now these theories are broken.

    GRAIL’s twin spacecrafts Ebb and Flow were launched in September 2011 and periodically make trajectory correction maneuvers that, over time, will lower their orbits to almost-circular ones at an altitude of about 55 kilometers above Moon.

  • Video: Gigantic New York-sized iceberg to crack, split from Antarctica

    Environmental experts were left in shock when they realized that a block of ice as big as New York metropolis is likely to split apart from Antarctica. If this happens, it will be world’s largest iceberg, say scientists, and the consequences can be catastrophic (scroll down for video and photos).

    The crack in Pine Island Glacier’s ice has a length of 30.5 kilometers, but even more worrying is the fact that it expands by about 1.6 km per month. If the piece of ice will break off, then it will feature an area of ​​about 906 square kilometers, which is an amazing size. The depth of the iceberg is impressive, having a thickness of 500 meters, of which only 48.7 meters above the surface. The rift is 78 meters wide along most of its length, but in some spots reaches a width of up to 240 meters. Its depth is 58,5 meters.

    The crack was first noticed from a DC-8 plane during NASA’s Operation Ice Bridge in October 2011 and one month later Terra spacecraft took snapshots of Pine Island Glacier from above showing the evolution of the ice calving. This would be the first time scientists can see the birth of a large iceberg.

    The cameras filmed the 5-cm high Lego man featuring Canada’s flag high into space untill the Earth curvature is seen and then the balloon breaks leaving the Lego come back to ground in a 32-minute free fall.

  • Photo: Earth’s close encounter with asteroid 2012 BX34

    Asteroid 2012 BX34 passed near Earth within 0.17 lunar distances on Friday 27 Jan. 2012
    2012 BX34 is a bus-sized asteroid which passed near Earth on Friday (Jan. 27, 2012) just a few days after it had been spotted.

    NASA claimed that the relative small size of these asteroids make them difficult to detect, but fortunately they feature no concern for Terra.

    Asteroid 2012 BX34 represented the 2nd space object to visit Earth this week after on 23 January another small rock -named 2012 BS1- was seen flying at 1.2 million kilometers away, a range which equals 3.1 lunar distances.

  • There is life on Venus, Russian researcher Leonid Ksanfomaliti says

    A Russian scientist reportedly published a report claiming evidence of life on Venus, the closest planet in the direction of the Sun.

    Leonid Ksanfomaliti, an astronomer at the Space Research Institute of Russia’s Academy of Sciences, came to this conclusion after analyzing images recorded by the Russian Venera-13 landing probe during its 1982 mission on Venus.

    Venus is as big as Earth, but it features a denser atmosphere which contains mainly carbon dioxide. So far, the probability of finding life on Venus has been regarded as slim due to the fact that the planet has an atmospheric pressure 92 times that of the Earth, a waterless and volcanic surface and a temperature of 894 degrees.

    Ksanfomaliti who submitted his revealings to the magazine Solar System Research, claims the Venera photos show objects looking pretty much like a “disk,” a “black flap” and a “scorpion.”

    “What if we forget about the current theories about the non-existence of life on Venus?” Ksanfomaliti wrote. “Let’s boldly suggest that the objects’ morphological features would allow us to say that they are living.”

Scientists involved in the project have not reported any life evidence, however they have not ruled out the odds of finding microscopic life forms on the surface.

    Leonid Ksanfomaliti says that the objects he spotted seem to “emerge, fluctuate and disappear” in various pictures taken from a variety of vantage points.

    The Venera series probes were developed by the Soviet Union between 1961 and 1984 to collect data from Venus. In Rusian language, Venera means Venus.

    10 probes from the Venera series successfully landed on Venus and broadcast data from the surface, including the two Vega program and Venera-Halley probes. Aditionally, 13 Venera probes successfully transmitted data from the atmosphere of Venus.

    The conditions on Venus are quite rough, as the lifetime of the probes on the surface spanned from 23 minutes (first probes) up to about 2 hours (last probes).
