A little interesting about space life.

The "lunar effect" is a term used to make a correlation between specific stages of the Earth's lunar cycle and deviant behavior in humans and possibly even animals. This is a pseudoscientific theory, which is one based on science but having no real scientific proof. It is also a theory studied within the realms of sociology, psychology and physiology and has for many centuries been a topic of studies and beliefs. Even the term "lunacy" is derived from the name Luna, a Roman moon goddess.



and here is another

The HST images also showed that the moon Kerberos is charcoal black in color, which is in stark contrast to the brilliant white of the other moons of Pluto. It was predicted that dust blasted off the moons by meteorite impacts would blanket the moons, giving them a homogeneous appearance. However, the reason why Kerberos is black remains a mystery.



and finally

During the entire Apollo program, the Soviet Union closely monitored all the transmissions of the astronauts. They would have been absolutely delighted to find it was a hoax. It would have been the greatest propaganda coup of all time. But apparently, the Soviets also didn't find any solid evidence of faked moon landings.

Earth's bewitching large Moon was probably born as the result of an immense impact, when a Mars-size protoplanet named Theia smashed into Earth about 4.5 billion years ago. This cataclysmic collision is thought to have hurled a vast amount of Earth-stuff and Theia-stuff into orbit around our ancient planet. Debris from the two unfortunate bodies gradually accumulated to give birth to our Moon, as tumbling little newborn moonlets crashed into one another and melded together into one large object.



Triton also possesses a thin atmosphere composed mainly of nitrogen, and a smaller quantity of methane. This atmosphere probably is the result of Triton's cryovolcanism, which is enhanced by seasonal heating from the Sun. Although little is currently known of Pluto's atmosphere, it is thought to be primarily composed of nitrogen with some carbon monoxide and methane added to the mix--and it is extremely tenuous. Pluto's very thin atmosphere may exist as a gas only when Pluto is nearest to the Sun (perihelion). For most of Pluto's very long year, the atmospheric gases are frozen in the form of ice on its extremely frigid surface. One year on Triton is almost 248 Earth-years long--or 90,471 Earth-days!



The astronomer Tycho Brahe, during the 17th century, measured the diurnal parallax of Mars that Johannes Kepler had used in order to make a preliminary calculation of the relative distance to the Red Planet. When the earliest telescopes to be used for astronomical purposes finally became available, the diurnal parallax of Mars was measured again in an attempt to determine the distance between our Sun and Earth. Giovanni Domenico Cassini was the first to make this measurement in 1692--but the early parallax measurements were hindered by the primitive quality of the instruments. The only occultation of Mars by the planet Venus was observed on October 13, 1590, by Michael Maestlin at Heidelberg. In 1610, Mars was viewed by the great astronomer Galileo Galilei, who was the first to make use of a primitive telescope for astronomical purposes. The Dutch astronomer Christiaan Huygens was the first to draw a map of Mars that showed terrain features.
