What life exactly gives!

Life is a perfect thing which God gave us.Human has one life in which he must do two things first:live good and second:to reach something especial in his life.Life isn't a toy like in the video games when you are having 3 or more lives and you can alive.in real life you have one heart which you mustn't gave it for something.Human has life to discover or make something and be different from others.For me life is  the biggest thing and I can do one different best something.Life is a machine which construction is very hard to explain but this construction works in the Universe.Let's take an example: for world scientists  the researching universe,planets,galaxies and Etc are the mane mission in there life.Let's take one more example: for a human mane mission in his life is to create family and take care of him his whole life and only this makes life especial  thing and human must agree this gift and take care of  him!

The Earth!

You know that Universe is big,so our home,planet Earth is a small part of big thing and this thing is Galaxy!
Have you ever thought about that we are a lucky Organisms(people), because,maybe there's a planet like earth and there's live Organisms like us but, maybe at this time we are alone,so we must take care of our planet earth.Because at this time  there's no planet which suggests us Climate and Atmosphere like an earth.You see that earth is our gift from the universe which we mustn't destroy,we must take care of him(earth).So people please take care of earth because it's our  one little home in the big Universe.
If someone will find our earth and will see what we are doing to earth no one will look us from a good side,please repeat this words in your hearts to become more lover to earth!
PLEASE, LET'S TAKE CARE OF OUR HOME,CALLED EARTH.

Beautiful universe

 NASA scientists at the agency's Jet Propulsion Laboratory in Pasadena, Calif., effectively have ruled out the possibility the asteroid Aphophis will impact Earth during a close flyby in 2036.

The scientists used updated information obtained by NASA-supported telescopes in 2011 and 2012, as well as new data from the time leading up to Aphophis' distant Earth flyby on Jan. 9.

WATER ON THE MARS?!

WOW THERE'S WATER ON THE MARS!
FROM:NASA.GOV

NASA-funded researchers analyzing a small meteorite that may be the first discovered from the Martian surface or crust have found it contains 10 times more water than other Martian meteorites from unknown origins.

This new class of meteorite was found in 2011 in the Sahara Desert. Designated Northwest Africa (NWA) 7034, and nicknamed "Black Beauty," it weighs approximately 11 ounces (320 grams). After more than a year of intensive study, a team of U.S. scientists determined the meteorite formed 2.1 billion years ago during the beginning of the most recent geologic period on Mars, known as the Amazonian.

"The age of NWA 7034 is important because it is significantly older than most other Martian meteorites," said Mitch Schulte, program scientist for the Mars Exploration Program at NASA Headquarters in Washington. "We now have insight into a piece of Mars' history at a critical time in its evolution."

The meteorite is an excellent match for surface rocks and outcrops NASA has studied remotely via Mars rovers and Mars-orbiting satellites. NWA 7034's composition is different from any previously studied Martian meteorite The research is published in Thursday's edition of Science Express.

"The contents of this meteorite may challenge many long held notions about Martian geology," said John Grunsfeld, associate administrator for NASA's Science Mission Directorate in Washington. "These findings also present an important reference frame for the Curiosity rover as it searches for reduced organics in the minerals exposed in the bedrock of Gale Crater."

NWA 7034 is made of cemented fragments of basalt, rock that forms from rapidly cooled lava. The fragments are primarily feldspar and pyroxene, most likely from volcanic activity. This unusual meteorite's chemistry matches that of the Martian crust as measured by NASA's Mars Exploration Rovers and Mars Odyssey Orbiter.

"This Martian meteorite has everything in its composition that you'd want in order to further our understanding of the Red Planet," said Carl Agee, leader of the analysis team and director and curator at the University of New Mexico's Institute of Meteoritics in Albuquerque. "This unique meteorite tells us what volcanism was like on Mars 2 billion years ago. It also gives us a glimpse of ancient surface and environmental conditions on Mars that no other meteorite has ever offered."

The research team included groups at the University of California at San Diego and the Carnegie Institution in Washington. Experiments were conducted to analyze mineral and chemical composition, age, and water content.

Researchers theorize the large amount of water contained in NWA 7034 may have originated from interaction of the rocks with water present in Mars' crust. The meteorite also has a different mixture of oxygen isotopes than has been found in other Martian meteorites, which could have resulted from interaction with the Martian atmosphere.

Most Martian meteorites are divided into three rock types, named after three meteorites; Shergotty, Nakhla, and Chassigny. These "SNC" meteorites currently number about 110. Their point of origin on Mars is not known and recent data from lander and orbiter missions suggest they are a mismatch for the Martian crust. Although NWA 7034 has similarities to the SNC meteorites, including the presence of macromolecular organic carbon, this new meteorite has many unique characteristics.

"The texture of the NWA meteorite is not like any of the SNC meteorites," said co-author Andrew Steele, who led the carbon analysis at the Carnegie Institution's Geophysical Laboratory. "This is an exciting measurement in Mars and planetary science. We now have more context than ever before to understanding where they may come from."

The research was funded by NASA's Cosmochemistry Program and Astrobiology Institute, part of the Planetary Science Division in the Science Mission Directorate at NASA Headquarters. The research also was supported by the New Mexico Space Grant Consortium in Las Cruces, and the National Science Foundation in Arlington, Va.
