Geoscientist Explains Strange Rock Formation on Mars
Missions to Mars have brought forth a lot of valuable information about the planet, not all of which has been explained as yet. One such unexplained mystery from Mars has been regarding rocks that have been found on its surface. Rocks in some parts of Mars have been found scattered in strange uniform formations. So far, no ready explanation had been provided for such a uniformly spaced formation of rocks. However, Geoscientist Jon Pelletier, from the University of Arizona in Tucson believes he has solved this mystery.
It has been believed for some time now that the high speed winds that occur frequently on the surface of the planet may have something to do with rocks being scattered in particular formations. However, this theory does not hold much weight, because despite being a very windy planet, the air in the atmosphere of the planet is so thin, that even at high speeds, the wind is incapable of carrying rocks in its stride. The rocks found in these uniformly spaced formations range from the size of a penny to the size of a football. It would have been impossible for the winds on Mars to transport rocks of such varied sizes from one place to another. It is even more improbable that the winds were responsible for dropping these rocks of different shapes and sizes in a uniformly spaced fashion.
While the wind is incapable of moving rocks from one place to another, it certainly can move sand that is present all across the surface of Mars. Geoscientist Jon Pelletier believes that it is this motion of sand that is responsible for the strange rock formations on Mars. And not just that, he believes that the sand makes the rocks move into the direction of the wind as opposed to along with it. Here is how he explains it:
When the wind blows, it moves the loose sand in front of rocks, creating a pit in front of it. On the other hand, some of the sand gets deposited behind the rock as it provides protection against the wind. This mound of sand prevents the rock from rolling backwards and along with the wind. Instead, when the sand in front of the rock gets eroded, it creates a pit, causing the rock to roll forward into the pit and into the direction of the blowing wind. This gets repeated over and over again as long as the wind keeps blowing.
When you consider the effects of this phenomenon on a cluster of rocks, here’s what happens: the rocks in front of the cluster are the first to be affected by the wind, while the ones in the centre and around the back remain protected longer. In the case of a cluster, the pit gets created on the side of the rocks and they end up rolling sideways. The mound of sand that gets created behind them prevents bunching up of rocks and as the wind keeps blowing, the rocks move further apart from each other, but maintain a formation along the original cluster.
Four Habitable Planets - Part 3
This is a continued post, part one can be found here and part two can be found here
Welcome to the third and final part of this three part series. Today I will go through the final world, as well as I will add the final part to it and a little extra information. Once again feel free to leave views on the post as they are always appreciated 
Water Worlds
These worlds would be basically entirely made of water. They would be the size of Earth roughly as well. There would be no boarders to stop the water overflowing like Earth has with rocks however. These planets can either be absolutely fabricated of baptize with aerial burden ice at the core, or they can accept bodies of aqueous baptize that are afar from a silicate amount by a blubbery band of aerial burden ice
One approach for life’s agent on Earth says amoebic actual calm in bank pools and again became concentrated by adhering to the apparent of rocks. Eventually, this aboriginal activity advance into the added ocean. Another approach for life’s agent is that the all-important allure occurred at hydrothermal agitable vents. On baptize worlds, however, these scenarios are impossible. Therefore, Bredehöft thinks activity is not acceptable to arise on such planets.
Summing It Up
Bredehöft came to a conclusion that planets similar to Earth would be best to look for life. He does however tell us that they will not necessarily cope any better to us due to conditions. For all we know, they could be an advanced race of humans! As it is only a matter of time before we can search other planets and moons for life; we will just need to stick to theories for now. Although good, they don’t stand up against much unless proof is found.
When asked what we are looking to find, Bredehöft said “something slimy”. 
I hope you all enjoyed the series of posts, have a great day
Four Habitable Planets - Part 2
This is a continued post, part 1 can be found here
Hey guys, back again with part two of this three part series. This will most likely be the shortest post of the lot, but tomorrows post will be the longest I would say. Anyway, I hope you enjoy the article and make some sense of it! As always views and comments are appreciated.
The third type of planet we explore are the icy worlds. These are the planets that have water underneath their surface, rather than above it. The moon of Jupiter, Europa is a perfect example of what is trying to be said here. However Europa is part the point in the solar system where ice can change to water. Apparently once it is past the certain point, it can no longer become water.
The acceptable appearance of accouter zones thinks of a bounded brilliant as actuality the prime activity source. Worlds like Europa however that are icy, added factors appear into play, such as the gravitational cull of additional planets. Worlds with aqueous baptize under icy layers could potentially be inhabited by simple bacilli admitting actuality far from the accepted accouter zone, so continued as activity is provided in some added way.
That concludes part two, part three will be up tomorrow!
Biggest Full Moon This Year
Friday we witnessed our biggest full moon of 2008. The Earth, Moon and Sun are held together by gravity. This keeps them in an orbit where neither collide but keep in a natural movement. This keeps us moving around the sun and the moon going around us. The moon takes a trip the whole way around Earth every 29.5 or so days.
Now normally the moon is around 380,000+ kilometers away from us. On Friday however it was only 350,000 kilometers away from us. The moon was also 14% times bigger and 30% brighter, according to NASA’s research. Now as the moon controls how the tides move, as it was closer the tide was higher.
Below are some moon facts you may find interesting to read!
1. The moon is always moving away from Earth; but interestingly it only moves 4cm a year. However the part I found really cool is; as the sun continues to get bigger it pushes the moon back towards Earth. This will eventually cause too much pressure and the moon will deteriorate and break apart.
2. As many of you will have heard, some star signs are effected by the moon; thus turning them crazy! This is a false statement and no real proof has been shown towards this accusation. There is also no such thing as werewolves coming out on a full moon; or at least I haven’t seen any - there always is a chance 
3. Due to high tides caused by the full moon; there is more pollution on beaches.
