NASA SOLVES 2,000-YEAR SUPERNOVA MYSTERY 

Nasa has finally found out how the first SuperNova occurred. The US agency said that Monday Spitzer Space Telescope found out that 2000 years ago Chinese Astronomers witnessed what turned out to be an exploding star. The findings show that the stellar explosion took place in a hollowed out cavity allowing material expelled by the star to travel much faster. Astronomers thought it would be at least three times bigger then they expected. In 185A.D astronomers saw a star in the sky that stayed there 8 months but in 1965 they determined that it actually was a SuperNova. 

How could this be good/bad for the society? Its not good or bad its actually good to know that Super Novas were discovered and more stuff about them. 

How did you find it? I actually had nothing to find so I thought space was a good thin to write about. 

Did it come from a reliable resource? Yes, Discovery is really reliable and has really interesting and cool stuff about everything all the time. 

What did you learn?  I learned that SuperNovas were discovered by the chinese and that they were discovered after A.D

Strange Life Found in Deepest Ocean

Oct,24,2011

Scientists are studying the deepest part of the ocean. It is called Mariana Trench. These animals I'm going t talk about xenophyophores. They are spotted in San Diego,Mariana Trench beneath 6.6 miles. They are a very interesting type of sea creatures and are highly adapted to extreme conditions. These small creatures are among the largest individual cells in existence. They usually grow bigger than 4 inches.Rapping particals from the H2O, xenophyophores can focus at high levels of lead, uranium and mercury and are thus likely highly resistant to gigantic doses of heavy metals. 

1. How could this be good or bad for the society? It is actually neutral for now.  

2.How did you find it? I was looking at the animals bar on Discovery and actually "deepest" took my attention.

3.Did it come from a reliable resource? Yes, Discovery is sometimes my last chance and I always find good articles 

4.What did you learn? I learned what the deepest ocean was.

Tittle: Seven Supernovas Found in One Galaxy  

Author:Andrew Fazekas 

Source:Internet 

Data:6,OCT,2011 

Some space satellite was able to find 7 different supernovas, it is impressive to have that many supernovas in 1 galaxy. The galaxy was Arp 220, Arp is 250 Million light years away. It is know that Arp 220 formed from the merger of two smaller galaxies and is well known to host a very intense burst of star formation, easily seen in visible wavelengths.Arp 220 Is causing many star deaths.Each of the supernovae found in Arp 220 spans less than a light-year, and at such a great distance, each radio signal covers an angle in the sky less than 0.5 milliarcseconds across, Batejat said. 

Reflection:

1.How could this be good or bad for the society? It does not affect the humans. It affects the stars because ARP 220has some special explosives. 

2.Why did you chose this article. I thought it amazing that people could go 250 million light years away and that there are 7 supernovas in a galaxy.  

3.How did you find it? I was looking on the front page of National Geo and I thought it was pretty cool. 

4.What did you learn?  I learned that there can be more then 7 supernovas in a galaxy and that the galaxy ARP220 exists

Title:Mercury:The Little Planet Full of Surprise
Author:Irene Klotz

Date:Thu September 29, 2011 02:00 PM ET
Summary:
This report is about how a space craft went to mercury to see what is happening on mercury it came back and gave more information. Mercury has a large iron core. Mercury seems to have created the same way as: Mars, Venus and earth. Mercury has immense lava flows that dumped miles of molten rock over gigantic territories of the planet. The Space Craft from NASA Show a new type of land form.
Volatile sources seem to be transforming from solid to gas. On Venus they find that volatile materials, such as potassium and sulphur which would be lost as temperatures spiked under either scenario are present on the planet today. There is also geological evidence for immense outpouring of lava that inundates the large areas of Mercury It is more then several miles deep. The rock was so hot it created channels that went on surface.

Paragraph 2:
1.How could it be good or bad for the society? It actually does not affect us people. This report had nothing to do with good and bad it was just a normal paragraph. 
2.What did you learn? I learned that this planet named Mercury is quite different the Earth. There is continuous lava flowing over half of the planet. It has resources and its core is made out of iron.
3.How did you find it? I like space and Discovery Channel. I was looking at the "Space" bar and found it. I thought it was pretty distinct. I have never done a Current Event about space.
4.Did it come from a reliable resource? Yes indeed it did, I can always count on Discovery  because its not the first time I use it. It always gives clear info.

Title:Giant Jellyfish Invasion
Author: Ruth A.Musgrave
Source:Internet 
Data:Oct,4,2005
Summery: The story talks about how these giant jelly fish attacked the seas of China and Japan.
The people are frightened of them because if they sting you you could die. They weight about 200 Kilograms.They can grow up to 6.5 meters and they grow up to 2 meters wide. These vast type of species are causing the fisherman problems because they are electrocuting the fisherman's net and spreading toxic substances.
Another theory suggests that seas heated by global warming are better suited for breeding, turning the Nomura's otherwise modest numbers into an armada.
These huge creatures can burst through fishing nets, as well as destroy local fisheries with their taste for fish eggs and larvae.

How could this be bad o god for the society? It is really bad because these creatures kill people and demolish the fisherman's net.

What did you learn? I learned that there are bigger and more dangerous jellyfish then I though. First I thought that the biggest jellyfish were 1.5 meters big.

How did you find it? I found it by National Geo. I didn't find anything before. I was looking and looking and then i found it and I thought it was scientific and cool.

Scientific Summer

This summer I have driven  the motor cross really fast. I did tricks and jumps and went really fast. I have had balance and I didn't fall.


          



What I think is scientific at motocross is that you have to hold your balance . It is also about the g-force. G-force is when you hit a curve how much you go in .

First Post

Hey guys,
Welcome to Alex's "Science Blog".

1. I want to work a lot this year .
2. I want to have fun.
3. I want to learn about solar system.
