Check out this webpage to really see just how big or small we are in the universe. Remember - it's all relative.

The Universe is Believed to be Flat
Watch the video below for a great description of our universe. There are some scientists that believe that the universe is flat. It gets a little technical in the middle but the entire video is definitely worth sitting through.

Inside the Space Station
Take a look at the video below to get an idea of what it is like inside the Space Station.

Spotting a supernova
This image, relased Nov. 15, shows a supernova known as SN 1979C within the galaxy M100. Astronomers say the supernova may contain the youngest known black hole in our cosmic neighborhood. In this composite image, the Chandra X-ray Observatory's view is colored gold. Optical data from the European Southern Observatory's Very Large Telescope are shown in red, green and blue. Infrared readings from the Spitzer Space Telescope are shown in red. The supernova is a bright spot just beneath one of the galaxy's spiral arms, near the central lower edge of the image.

Video on the Milky Way Galaxy
I was talking in class about an episode of "The Universe" specifically on the Milky Way Galaxy. This is the episode I was talking about. They get into detail about black holes at the center of galaxies, what it is like near the center and the edge of a galaxy by the Milky Way, etc..... Watch it on You Tube. I have attached a link for what I showed in class. You can watch the other portions of this episode on YouTube also.
There are other episodes of "The Universe" that can be found on Hulu such as documentaries on Quasars and Pulsars, Nebulas, etc.... Check them out.

Sunspots and Solar Flares
NASA's Solar Dynamics Observatory captured this extreme ultraviolet view of furious magnetic activity on the sun on July 9, 2010. The thin arcing loops are really particles spiraling along magnetic field lines above the active region.
Watch video below for a better understanding of the Sun's magnetic energy.

Solar Activity on August 1, 2010
The Sun showed some amazing activity in early August 2010. The photo below shows color differences where there were heat variations in the Sun.
Solar Twister
A twisted filament of magnetism on the sun suddenly untwisted on Oct. 28. The result was a spectacular eruption recorded in full-disk detail by NASA's Solar Dynamics Observatory. The solar twister can be seen here rising from the 10 o'clock position on the edge of the sun's disk.

Life Cycle of a Star
View video below to view how a star moves through its life cycle. Stars begin their lives as protostars, then become a main sequence star for the majority of its life cycle. When the gas hydrogen is used up, the helium is ignited and the star becomes larger - a red giant. As the helium is used up, the star begins to pulsate which indicates it is in the throws of death. When the star sheds its outer shell, the white hot center remains (white dwarf) which will glow and then eventually peter out.
Look at the video below to understand the life of a star.

Jupiter is the Solar System's Vacuum
As asteroids or other debris pass Jupiter, the gravity of Jupiter will pull a large amount of this matter towards it. Jupiter's impressive size is accompanied by a large gravitational force which pulls objects travelling through our solar system towards it. In this regard, Jupiter acts as a cleaner of debris that could otherwise hit Earth or our moon. What other natural phenomenon exist in the solar system that enables life on Earth to continue?
Saturn's Moons
The Cassini mission orbited Saturn for 4 years. It was the longest mission to Saturn and has collected data that will be studied for years to come. Below are pictures of some of Saturn's moons.
The Saturnian moon Rhea looms large above the small moon Epimetheus in this picture from the Cassini orbiter, released May 21. The two moons are actually separated by almost 150,000 miles, with Saturn and its rings in the background.
The light surface of Saturn's icy moon Dione is rendered in crisp detail against a hazy, ghostly Titan in the background. This picture was taken by the Cassini orbiter on April 10 and released on June 21.

If the Earth had Rings like Saturn
How would our sky look if Earth had rings like Saturn? These pictures are good because it shows the rings at different latitudes on Earth and gives a good perspective of what they would look like.

Neptune will make its first orbit around Sun since 1846 in 2011
It takes Neptune 164 years to go around the Sun one time - its revolution period. It is over 4,498 million kilometers from the Sun. The distance of a planet to the Sun will dictate how long it takes for that planet to go around it. How long does it take for the Earth to revolve around the Sun? It is approximately 150 million kilometers from the Sun.

New Goldilocks Planet?
A new planet able to sustain life? Read the article below about the new planet discovered in 2010. The picture above shows the orbits of the planets orbiting the star in that solar system compared to the orbit of the inner planets in our solar system. The position of the new planet in the orbit around the other Sun is what makes it possible to support life. You can see that the orbit is smaller than that of Earth's but, the star in that solar system is smaller which would allow the planet to be closer without burning up.
Comparing the Gliese 581 to Our Solar System
The orbits of planets in the Gliese 581 system are compared to those of our own solar system. The Gliese 581 star has about 30% the mass of our sun, and the outermost planet is closer to its star than we are to the sun. The fourth planet, G, is a planet that could sustain life.

Meteorite falls to Earth
A meteorite fell to Earth and was caught on tape on a police cruiser's dashcam. This happened in Canada in 2009. As meteors enter the atmosphere, they start to burn up - this is the glow you see as it comes toward the surface of the Earth. The footage is shown twice. What would you have thought if you had seen this?
