About Deep Space Objects and Cosmic Terms
to Find the Latest Astronomy Images
Space Telescope Images: http://hubblesite.org/newscenter/newsdesk/archive/releases/image_category/
the magnificent Hubble Space Telescope images are here, with captions
— many with detailed background information and explanations
of the pictures. You can check the latest images, browse the ones
their staff consider to be Hubble's "greatest hits," or search for
objects of interest to you. Since the pictures are not under copyright,
they can all be downloaded in various formats completely free.
Optical Astronomy Observatory Image Gallery: http://www.noao.edu/image_gallery/
National Optical Astronomy Observatory (NOAO) includes a number
of major telescopes in the United States and in Chile. Some of the
best images from NOAO's instruments are collected and organized
at this site and they too are free for private use.
Picture of the Day: http://antwrp.gsfc.nasa.gov/apod/astropix.html
astronomers Robert Nemiroff and Jerry Bonell feature one relatively
new celestial image each day with a brief non-technical caption.
Over the years, some of the best astronomical images have been featured
and an index is available on site.
Southern Observatory: http://www.eso.org/outreach/gallery/astro
growing album contains images from the large telescopes in the southern
hemisphere run by a consortium of European countries. With the building
of the Very Large Telescope in Chile, which will be the biggest
telescope in the world, there is an increasing number of important
new images on this site.
Observatory Image Collection: http://www.aao.gov.au/images.html
site provides a marvelous library of images (focusing on nebulae
and galaxies) taken using large
telescopes in Australia. Many are by David Malin, who is acknowledged
to be one of the finest astronomical photographers of our time.
Includes captions and ordering information. (Note these images are
Image Galleries: http://coolcosmos.ipac.caltech.edu/
site collects infra-red images from space missions and telescopes
on the ground and also offers an intriguing set of comparisons showing
images at visible and invisible wavelengths. Note:
To get to the picture collections, wait for the top page to load
and then click on "Image Galleries."
Radio Astronomy Observatory Image Gallery: http://www.nrao.edu/imagegallery/php/level1.php
you can find pictures constructed from radio waves, collected by
a variety of U.S. radio telescopes. The universe as seen with "radio
eyes" is quite different from the universe visible light reveals
X-ray Image Gallery: http://chandra.harvard.edu/photo/category.html
Chandra x-ray telescope (in orbit around Earth) has been sending
back a wide range of images of what deep space objects would look
like if seen with "x-ray sensitive" eyes. The images are arranged
by category for easy sorting.
Sites for Asking Astronomy Questions
you have a question about astronomy not answered on our web site,
here are some sites where astronomers are answering questions from
the public. Before you ask your questions at a particular site,
check out their archives, where former questions from
others and the answers the scientists provided are available for
all. Chances are someone has asked your question already, and you
can get your answer instantly.
an Astronomer at Lick Observatory: http://www.ucolick.org/~mountain/AAA/
students and staff members at this California observatory answer
selected questions, particularly from high school students. Contains
archives and links.
about Astronomy: http://curious.astro.cornell.edu
"ask-an-astronomer" site run by graduate students and professors
of astronomy at Cornell University. Contains searchable archives.
an Astronomer for Kids: http://coolcosmos.ipac.caltech.edu/cosmic_kids/AskKids/index.shtml
site run by Linda Hermans-Killam at Caltech's center for infrared
astronomy. It lets kids submit questions and also read the answers
to questions other kids have asked.
the Astronomer: http://www.astronomycafe.net/qadir/qanda.html
site, run by astronomer Sten Odenwald, is no longer active, but
lists 3001 answers to questions asked in the mid-1990's. They are
nicely organized by topic.
the Space Scientist: http://image.gsfc.nasa.gov/poetry/ask/askmag.html
only answers questions about the Sun and the Earth, but has an archive
of more general questions, answered by astronomer Sten Odenwald.
a High-Energy Astronomer: http://imagine.gsfc.nasa.gov/docs/ask_astro/ask_an_astronomer.html
and answers at NASA's Laboratory for High-Energy Astrophysics that
focus on x-ray and gamma-ray astronomy, and objects
such as black holes, quasars, supernovae, and bursters.
Mr. Sunspot: http://www.nso.edu/sunspot/pr/mr_sunspot.html
for and answers by the staff of the National Solar Observatory,
with a particular focus on the Sun and the Solar System. Note:
A much more specialized site, just for questions about the Sun,
has been set up by the team for the SOHO satellite at: http://soho.nascom.nasa.gov/explore/drsoho.html
an Infrared Astronomer: http://coolcosmos.ipac.caltech.edu/cosmic_classroom/ask_astronomer/faq/index.shtml

of physics questions answered, with some astronomy as well, at this
physics education site.
Astronomy Pantry of Bitesize Answers: http://www.badastronomy.com/bitesize/pantry.html
Phil Plait started this site to deal with astronomical mistakes
and misconceptions in the media, but has expanded it to give brief
answers to questions on a variety of astronomical topics. Contains
a table of contents, organized by topic.
