p. 832 Galaxies and the Universe
Astronomy
Education & Outreach
Visit this site by the Center for Astrophysics & Space Science,
University of California, San Diego to find out more about galaxies
and the universe. You can choose to learn more about the scale of the
universe, stellar evolution, telescopes, black holes, galaxies, and
much more at this site. Scroll down and click on the big bang theory
for a brief history of the universe. Using Hubble Time, what
is the estimated age of the universe?
The
Milky Way Galaxy
At this site by the Students for the Exploration and Development
of Space (SEDS) you can learn all about the Milky Way Galaxy. The Milky
Way is just one of the many galaxies in the universe, and it is a spiral
galaxy. Astronomers have taken photographs of other spiral galaxies,
and all have a bulge in the middle. What is the galactic center of the
Milky Way?
Journey through the Galaxy
Go to this site to find out more about stars, planets, nebula, and the
Milky Way Galaxy. Read the short introduction about the Milky Way to
learn how it is classified. Then click on any of the links to see more
information about the solar system, stars, planets outside our solar
system, and the future of the galaxy and universe. What is the diameter
of the Milky Way?
The
Milky Way – Our Galaxy
Visit this site by Leicester University in the United Kingdom
to find out more about the Milky Way Galaxy. This site provides a clear
and readable description of the Milky Way Galaxy and its position in
relation to other galaxies. It also describes the formation of the Milky
Way Galaxy. How many stars does the Milky Way contain?
Imagine
the Universe
Go to this National Aeronautics and Space Administration (NASA)
site to find out what is known about the universe, how the universe
evolves, and the kinds of objects the universe contains. To find a subject
you want to explore, go to the icons just above the search bar. Click
on Exhibit central to see a list of videos, exhibits, and activities.
Then click on you be the Astrophysicist to solve the mysteries of the
universe. Pick an astronomy question and follow the clues given to see
what it is like to be an astrophysicist.
p. 846 Quasars
When
Did the First Cosmic Structures Form?
Visit this NASA site to learn more about quasars. Quasars are
the most distant distinct objects that astronomers have been able to
detect. What are quasars believed to be?
Hubble
Surveys the "Homes" of Quasars
Go to this site for a press release about quasars that have
been detected by the Hubble Space Telescope. Astronomers have discovered
quasars in a variety of galaxies, some of which are violently colliding.
Why do astronomers think quasars may be relatively short-lived phenomena?
Black Holes and Quasars
At this site by the Astrophysics & Space Research Group, University of Birmingham you can learn more about black holes and quasars. How much do you already know about black holes and quasars? How are scientists able to see black holes?
p. 854 Fermilab
Fermi
National Accelerator Laboratory
Visit this Fermilab home page to learn more about this laboratory.
You can go on a virtual tour of the lab, find out what research is underway
there, and find answers to your questions. Click on what is Fermilab
to learn about its mission and history. Who was Enrico Fermi?
The
Tevatron
Go to this Fermilab site to learn more about the Tevatron, the
world’s most powerful particle accelerator. The Tevatron is the complex
of ever-increasing energy accelerators at Fermilab. Once the protons
are accelerated to their final energy levels, what can scientists do
with the resulting proton beam?
