Strange astronomical things...
« on: October 24, 2010, 01:20:36 pm »
The purpose here is to post "abnormal" things related to the classifications for example. Not weird pictures, we have already a thread for these...
Here this magnificent spiral is absent of the NGC catalogue, absent too of the IC catalogue, and UGC catalogue !! Only present in the MCG catalogue !! That's strange, isn't it ??

Here is another great spiral on edge, bright and beautiful, which is absent of all the main catalogues... Has only a MCG number... Strange, isn't it ?
(I precise this about catalogues, it's more or less : M > NGC > IC > UGC > CGCG > MCG...)

14th Magnitude should have been visible.  But on the other hand there is such  a lot of sky when you're surverying at high magnifications & small visual fields.  Everybody gets tired at some point.

An incorrect spectra chart:

I copied my post (quoted by ES) from the thread "Newbies, post your spectrum questions here":

587730847964660245 http://www.galaxyzoo.org/examine/AHZ50000rx

I find, that this spectrum looks strange. Since I have no knowledge about spectra, I don't know, if it's really strange:



Everything to the blue of 6000Å is meaningless--the result of some kind of instrumental failure.

Best regards,
ES

I copied my post from the "UGC Catalog" thread:


UGC 09603 GPair

PS: I wonder, why the 3rd galaxy isn't listed in the UGC Catalog?! ???

These 2 galaxies are "touching" and nevertheless they have no following numbers in the UGC catalogue : UGC 06204 and 06207. Why ?? (I suppose that numbers "follow" as objects "follow"...)

I sent it on "stars"thread and was advised to ask here.
Here is a star, absolutely all criteria met visually, no redshift, classified as G.

ID: AHZ40002uj
Survey: GEMS and GOODS-S
Survey reference: 90020571

Well, I have another star classified by NED as a Galaxy

ID: AHZ40001x2
Survey: GEMS and GOODS-S
Survey reference: 90017526

COMBO-17 23343                 03h33m24.9s -27d53m00s G         ...       ...

Hello !
What are this ??
http://zoo-hst.s3.amazonaws.com/9004579111.jpg
http://s3.amazonaws.com/zoo2_extra/344321.jpg
Hello, kubaregis, welcome to the Zoo.
The first one is a modified image of a bright object (QSO?) You can see the original if you go back to the site.
The next one is a common satellite trail. Counts as artefact. See more here[url].
Have fun.
Rita

Hi, this is what I spotted:

Well isn't it a bit too bright for Redshift: 0.789051 and a normal galaxy?
ID: AHZ40003zq

NED lists 5 objects within a gnat's whisker of the center of the target.  I think you get all of them at once.

object   RA   DEC Type    z
COMBO-17 46562  03h32m47.9s   -27d41m48s   G 0.733000
COMBO-17 46448  03h32m47.8s  -27d41m51s   G 0.528100
COMBO-17 46260  03h32m48.0s  -27d41m51s   G 0.043000
COMBO-17 46490  03h32m48.2s  -27d41m52s   G 0.696000
COMBO-17 46312  03h32m47.5s  -27d41m50s   G 0.956000

I find a bit strange that this majestic spiral has only a number in the MCG catalogue... and not in the UGC or IC catalogues..

Same case. Bigger than the galaxy above but only a MCG number !!...
