- Cosmology website and FAQ given by SFN members :
Ned Wright's cosmology website and FAQ. He teaches the undergrad and graduate level courses in cosmology at UCLA and is also one of the team in charge of the WMAP satellite observing the CMB.
Wendy Freedman and Michael Turner's "Measuring and Understanding
the Universe" : http://arxiv.org/astro-ph/0308418
Note : a lot of good astronomy links are graphic rather than verbal, such as images from the HST and computer animations, also Ned Wright has a calculator that lets you calculate from something's red shift how far away it is.
Here are good online cosmology calculators :
- Siobahn Morgan's :
and Ned Wright's :
Professor Murphy's online calculator(Johns Hopkins) :
All you ever want to know about Nebulas:
Here is a nice free star chart that comes out every month and it also comes with a list of objects to look for with binoculars - a large telescope: http://www.skymaps.com/
A good place for science books... Their Starry Night program is quite simple but would at least help you through the apprehensive feeling of not knowing what your look at. It also updates off the web the daily coordinates of several interesting objects each night, for locations all over the globe : http://www.whfreeman.com/astronomy/
Good place for WMAP data : http://lambda.gsfc.nasa.gov/
Trove of stuff on relativity, it helps if you know roughly what you are looking for, and keep in mind that reading it on the web sometimes mean it has not been peer reviewed. Some of the ideas in here (^that link^) are misleading, but its still a very good challenge trying to grip some of the concepts laid out : http://relativity.livingreviews.org/Forms/search.html
While at first a ghastly sight to look at the links in the light green are a good place to start surfing to try and skim some knowledge off the information superhighway! http://academics.hamilton.edu/physi.../resources.html
If you want star maps and much more for any location and time you can try the following program(A good graphics card with OpenGL driver is a must. (Geforce 4 or later) :
To add stars to mag14 you can find them here. (just copy them in the right directory)
You do need a serial number to make it work
You can get a 15 day trial key here:
(if 15day's isn't long enough to test it there are places to get a less limited key)

The GRB Coordinates Network (used to be called BACODINE) system (1) calculates RA,Dec coordinate positions of Gamma Ray Bursts (GRB) detected with BATSE and distributes those positions around the world in real time -- a few seconds! -- so that other instruments can make follow-up observations in other wavebands while the burst is still bursting! (2) distributes locations of GRBs detected by other spacecraft. (3) distributes reports follow-up observations made by ground-based optical and radio observers.
These three functions provide a one-stop shopping network for follow-up sites and GRB researchers.
How to present rotation curves of Galaxies ? (Galaxy Rotation Curves) - http://www.equidem.de/RCAtlas/
An alternative way to present astronomical data by combining atlas and catalogue features: The Galaxy Wanted Poster. The Halpha and NII spectra of nearby spiral edge-on galaxies reveal next to their red shift velocities their individual kinetic fingerprints. Such velocity slices or rotation curves are correlated to the morphological properties of these objects. Based on a sample of 59 galaxies of the southern hemisphere a small rotation curve atlas has been compiled which allows fast comparison between visual and spectral observations.
