Keep Bad Astronomy close to your heart, and help make me
filthy rich. Hey, it's either this or one of those really
irritating PayPal donation buttons here.
Okay, so there are more than 10. There are a lot of good sites out there!
To a large extent, people's interest in astronomy is due to
the beautiful images we are now almost accustomed to seeing. Probably
the best place on the web to find such stunning images is the
Astronomy Picture of the Day,
where Robert Nemiroff and Jerry Bonnell put pictures they have culled from
many thousands on the web, along with a short easy to understand explanation
of the science behind the picture (as well as lots of links). This is
a great place to start a web browser, and they archive every image
so that you can take your time looking through the Universe.
Looking for the current space and astronomy news? There are lots of news sites
out there, and my friend Fraser Cain collects the best stuff on his website
The Universe Today.
It's updated daily with news and information about, well, the Universe today.
Ned Wright's
Cosmology FAQ is also a fantastic place to answer any questions
you have about black holes, the Universe and everything.
One of my favorite sites on the web is
The Nine Planets, an astonishingly complete and well-written tour
of the solar system. This is up to date and extremely well done. For
my money, this site is one of the reasons we have a web in the first place.
This one is so cool:
Heavens Above Satellite Visibility Page
lets you enter your home coordinates, and then displays information
about visible satellites! It lists Iridium satellites, Hubble
and many others. You can also create local sky maps for different times,
and track asteroids. Very cool. Try it out on the next clear night!
Nick Strobel's astronomy lectures is a site with extensive
information about basic astronomy with diagrams. He has great descriptions
of things like the seasons, tides and the like. I have used his diagrams
myself during talks.
Sten Odenwald's
Astronomy Cafe is an excellent site to get your
astronomy questions answered.
I'm not just saying that because he works down the hall from me; he has
ben answering questions from around the world for two years now and has an
extensive archive of answers. Check there before going any further!
James Randi
is the skeptic's skeptic, ready, willing and able to debunk
everything from psychic powers (he has put Uri Geller to the test many
times) to UFOs, ghosts and well, everything else. A Must Read.
It may seem weird to you, but I will put
NASA's Goddard Space Flight Center's Library as a top link. Why?
Because it is a treasure trove of information, and not just a place to
find books (though I use it for that a lot). They have web resources,
links to online astronomical journals,
a kids' page, and even
electronic books: whole books online that you can read. Amazing!
If you're trying to separate fact from fiction when reading a website,
you might want to check out
Crank.net, which rates "alternative" science sites on their
level of lucidity. The "cranky" sites are usually entertaining,
while the "crankiest" may insight stomache aches. He lists
"anti-crank" sites as well, if you need an antidote to the
wackiness.
CSICOP, aka the Committee
for Scientific Investigation of Claims of the Paranormal is one of
the leading skeptical organizations out there. Fed up with claims
about Bigfoot, UFOs and ghosts? This is the place to go.
They also have a
list of skeptical
resources, too.
The Bad Archaeology page has lots of bad and good archaeology on
it, and links to skeptical pages too.
The Skeptic Friends
Network has lots of resources for skepticism in general, as well as
a fun bulletin board where folks discuss skeptical and gullible thinking.
DangerousIdeas.net answers the skeptic's most often asked question:
"What's the harm in believing in pseudoscience?"
This site keeps track of people
who get bilked, who make wrong decisions, and yes, some who die because
they believe in something when a bit of critical thinking would have saved them.
Banachek
is an interesting fellow. years ago, he fooled a lot of
parapsychologists into thinking he was The Real Thing.
The story is on his site, and is pretty funny.
The Glossary of Mathematical
Mistakes has a long list of common errors people make when they
are unfamiliar with using math. That means pretty much everybody.
He has the famous proof of "1 = 2" and lots of others.
This one isn't exactly bad science, but it is a great skeptical page
which debunks a lot of nonsense:
The Way of the Dodo takes on chemtrails, the face on Mars, and
even hollow Earth theories.
Sky and Telescope has started a daughter magazine for beginner
astronomers (young and old), called
Night Sky.
I happen to write a column fro them too, called
"Straight Talk".
PSIgate is a list of hand-picked science websites covering a vast
array of topics. It's searchable too!
This isn't really the right category, but it'll have to do:
The Scientific
Defense of Astrology is a fair and even-handed treatment of
astrological claims. Some of the web sites on that web ring
(called "Boundaries of Science") are at best borderline crackpottery,
but this site is a lot of fun.
KidsAstronomy
has info and fun pages for the wee ones in your life.
The Science Education
Partnerships Orcale has many links to places where you can
Ask-A-Scientist all sorts of questions. The SEP links schoolkids
to scientists via the web, a wonderful proposition.
Eisenhower National Clearinghouse
is an extensive website of information for teachers and other educators.
I have only scratched the surface there and found a wealth of info.
If you ever teach, this a great place to poke around!
The Stellar Visions
Webring homepage is a slickly done site with many links to astronomy
websites. It's a nice way to easily visit a lot of different astronomy sites.
My friend and colleague
Jim Kaler, who is a professor of astronomy at the University of
Illinois at Champaign Urbana, has a link to Bad Astro from his
Astronomy
101 Course page. Jim has written many popular astronomy articles
and is also the author of a very successful textbook for undergraduate
astronomy called
"Astronomy!".
I have a copy on my bookshelf right
behind me and I use it as a reference all the time. It even has an
image I took of a planetary nebula in it!
The Astronomy Net
has an astonishing list of astronomical resources on the net.
This is a great place to look for something you need. They also
have several bulletin boards for discussing different topics.
The Astronomy Mall
is a good resource
for people looking to buy telescopes and such.
The Amateur Sky Survey is a project designed to look for
bright objects (comets, asteroids, supernovae, etc) over large
areas of the sky. The project staff is comprised of both amateurs and
professionals, and they hope to distribute these low cost cameras and
support software around the world. This way, there would be 24 hour coverage
of the entire sky. This is an ambitious project, and I am highly impressed
by their determination and knowhow.
