Each galaxy contains many billions of stars. The galaxies in the center and upper right are barred spiral galaxies. The one in the upper left is a spiral galaxy while the one in the lower left is an elliptical galaxy. Notice the colors. Yellow – gold galaxies would be older with less energy.

Glossary
Have you ever seen shuttles launch? The ground shakes and the noise can heard for many miles. The Americans launch most of their rockets at Cape Canaveral, Florida. From here the first astronauts went into space as well as the Apollo astronauts who went to the Moon.

Time is relative to speeds, locations and distances. A measuring constant astronomers use is the speed of light in a vacuum such as space. But some scientists are beginning to wonder… What if light changes speed in vacuums?
When travelling close to light speed, the vision of the star field distorts and turns shades of blue. Also time will slow on board the ship relative to the pace of time outside it.
When something is moving away from you at a very great rate of speed, the color will shift to red.
These blue and red shifting are called Doppler Shifts. It is a way of detecting if something is moving towards or away from you rapidly.

You see that an aurora borealis can occur on Saturn as well as Earth. What else can you see, concerning this event, that they have in common?
In your own words, describe the atmosphere that is between you and space. Describe its: support of life, protections and its flexibility of stopping space objects yet allowing air travel.Minimum 50 words.
Have you ever thought of what is between you and the dangers of space? Just thin gasses!It allows bullets to go through it, yet stops dangerous cosmic rays and mid sized asteroids and comets.

These are pictures of the famous: “Face on Mars”. The above picture was taken by Viking probe in the 1970s. The picture to the right was taken by another probe in 2001. Hmmm… Why do they look so different? Write down your best guesses. Minimum 25 words.

In this example, we can detect the planet by silhouette or less starlight as it passes between us and the star. Both techniques need computer technology to detect the minute variances.
The Huygens / Titan space probe took these pictures. To the right is a picture it took when it landed. The one taken below was from an altitude of nearly five miles. Write down five observations.
Comet Hale BoppA 36 mile wide comet! It was visible without telescopes for 18 months ,over the years 1996 and 1997. The next time it will drop by is in the year 4385.
Say hello to my little friend: Eros! It is 21 miles long and has a thickness of 7 miles.

Why do you think Vesta is so oddly shaped? Write down your opinions.
Observation:Notice there are two stars.One is close and the other is distant. It takes time for light to travel .Which star has light that takes a longer time to travel to you?Therefore, which star are you seeing further back in time?Why?
Having trouble? See the next slide.
JAS EP

Sorry for the trick question. The stars on the previous slide are exactly the same distance from you. Don’t believe it? Touch the stars on the screen.Therefore, in this situation, it takes the same time for the light to reach you.You may have experienced the problems past astronomers encountered. How can you tell which stars are closer? What is needed is a marker in space to judge distance. It took many years to figure out how to the measure distances and it is still not an exact science beyond certain distances. You will cover the remedies for distance dilemma in your textbook.
One star is smaller and dimmer than the other. You can’t always judge distance by only the sizes or brightness. The further the star is away from you the farther back in time you are seeing it.
Write down in your own words what you learned about light, distance, apparent magnitude (size) and apparent brightness from these two slides.50 words minimum.
As a star converts from burning hydrogen to helium fuel it changes color , cools and expands. According to science predictions, far in the future the Earth will be inside the outer atmosphere of an expanded red giant - Sun.The Earth will end up a blackened cinder ball.

This is a photo of a black hole spewing out radiation. It is located in the M87 galaxy. It has already consumed the equivalent of two billion stars!
Observation:When we scan the heavens at night, why do we see space that is only black and white? Is it a good thing that we see space mainly in black and white? What if the night sky was full of color, would if be a sign of danger? Why or why not? Write down your opinions.
