Som en motgift vil jeg anbefale dette nettstedet, hvor man kan registrere seg for å lære å analysere og klassifisere galakser, og delta i en stor vitenskapelig undersøkelse (der falt vel 96% av leserne av lasset, kan man formode).
De fire prosentene som framleis er med, kan her bl. a. lese om:

The Science
What do we want to know?
Galaxies, made up of billions of stars like our Sun, are the beacons that light up the structure of even the most distant regions in space. Not all galaxies are alike, however. They come in very different shapes and have very different properties; they may be large or small, old or young, red or blue, regular or confused, luminous or faint, dusty or gas-poor, rotating or static, round or disky, and they live either in splendid isolation or in clusters. In other words, the universe contains a very colourful and diverse zoo of galaxies. For almost a century, astronomers have been discussing how galaxies should be classified and how they relate to each other in an attempt to attack the big question of how galaxies form.

Oxford University News Release: Bumper Christmas for Galaxy Hunters
Press Release: 20 December 2007
Armchair astronomers using the galaxyzoo.org website have identified over 500 overlapping galaxies in the local Universe when astronomers had previously only known of 20 such systems.
"This is the best Christmas present our users could hope for!" said Dr Chris Lintott of Oxford University, a member of the galaxyzoo.org team. "Overlapping galaxies are useful because they enable us to study the dust in each system. Dust grains play a crucial role in the evolution of galaxies and how we see them - the presence of such dust is critical for star formation."
Visitors to galaxyzoo.org get to see stunning images of galaxies. By classifying some of these images visitors are helping astronomers to understand the structure of the universe. The new digital images were taken using the robotic Sloan Digital Sky Survey telescope in New Mexico.
Each of the 500+ overlapping galaxies was discovered by a member of the public signed up to the galaxyzoo.org forum where armchair astronomers can compare notes on the images of galaxies they have seen and classified using the website. The search for overlapping galaxies was led by Bill Keel of the University of Alabama who wrote on the forum asking people to look out for suitable systems.
Astronomers have been awarded five night's use of the WIYN telescope on Kitt Peak, Arizona, to take a closer look at the overlapping galaxies identified by the Galaxy Zoo volunteers. The WIYN telescope is one of the largest in the Northern hemisphere and one of the most advanced in the world. This work will begin on 25 April 2008.
"We are expecting to get some spectacular images from our Arizona nights but, with the first set of science papers on Galaxy Zoo coming out very soon, we still need more volunteers to visit galaxyzoo.org" said Dr Chris Lintott. "Even if you've visited the site before, please come back and classify some more galaxies in between mouthfuls of turkey and Christmas pudding as we need your help to confirm our results, results which could have a profound impact on our models of the universe."

How to Take Part - Tutorial
Dear Passopp
Your job is very simple! All you need to do is look out for the features that mark out spiral and elliptical galaxies. In fact, as you're a human and not a computer, most galaxies should be easy to classify since they're obviously spirals or obviously ellipticals. On this page, you will practice classifying galaxies. On the next page, you will take a short trial to test your skills. If you don’t pass the trial, you can try again. Once you pass the trial, you can start contributing to Galaxy Zoo science!
