I just used the data for that galaxy and pushed it through the same anaylsis as I am subjecting the Irregulars to...   ;)

Oh let me just a moment stay
where time is not and angels play the paeans of the galaxies;
then speed the stardust on its flight
to change dread darkness into light, cold chaos into ecstasy!

I was given this beauty to classify and did so, but I am wondering what the round black spherical areas are - I don't know that they're objects.  thanks

Welcome to the zoo CVM87 :)

Pixellation, basically. It's a very distant galaxy, and the black areas are areas that aren't full of stars and lighting that part of the image up!

I'm curious as two how others classified this irregular?  Is it to separate objects or one object that as been dismembered?  Is the round blob a central core with the right side object being the stars and gas/dust that has been dragged away to create a star forming region?

The second question is "Click NOT IRREGULAR if it is a spiral, Eliptical, or a Merger or you don't know".  This looks to me like a merger .  This is the most important question of all, it is to weed out the others that got into the irregular galaxy topic in the forum.

Thanks for starting again, 3094 clicks are now needed to complete the third data set (the one I will concentrate on)

I'm a VERY newbie, having completed only two sessions of classifying.  I've learned a lot from the forum but don't have time to look through 16 or more pages on each of several threads.  It would be very helpful if  some of the information in answers to questions in the forum could be added to the tutorial.  Three examples:  the ring of blue and red dots around smooth galaxies being stars;  what to do when there is a dark central dot in the middle of a bright core;  asteroids creating a line of blue-grreen-red "clumps".  I misclassified at least three objects in my first session because I didn't have this information.  Surely the database would be more valuable if errors like mine could be avoided!  Thanks -

I'm an absolute newb (both on the forum and in astronomy) and please, do excuse me if these are extremely inept questions (or if they've been asked before).. But then again, how else am I going to learn?  ;D
When I click the "Indicate Photometric Objects" it circles most of the objects appearing in the image, but not all of them. Some of the objects also overlap the galaxy. When I click "Objects with Spectra" it only highlights ONE object. I'm not really sure what these two buttons are supposed to show me?

Welcome to the Zoo! As far as I understand, photometric objects are objects photographed and then given a basic analysis,
such as filter readings and type of galaxy, whereas objects with spectra, of which there are much fewer, give a more detailed
analysis as their spectra have been taken (obviously). Spectra are taken with a manual plate with holes, fitted to the telescope,
so as this is a laborious process, spectra cannot be taken for all objects.

Overlaps are when two photometric objects are close to each other and so the marked circles coincide with one another.

globular clusters??? I searched Analysis Tips and only say on ref

I just looked at something that looked a lot like 1, but I didn't find button for "globular clusters"

Is that right?
