The Netherlands Institute for Radio Astronomy made a recent press release about their new find, a unknown Giant Radio galaxy (GRG) centered around UGC 9555 galaxy triplet group. The material that was detected was ejected from the galaxies millions of years ago and would be about the size of the full moon as seen from Earth and is extending millions of light years across intergalactic space. The center of the new GRG is associated with the central galaxy and is located at a redshift of z=0.054536, or 750 million light years from Earth.

I had observed this group a few years ago when I was doing the Rose compact galaxy groups and after the press release I put it on my list to revisit for this dark time observing. I observed it several times the past few days and under excellent conditions last night from 375X to 813X with 10 out of 10 transparency! I was able to see five galaxies near this group. One SDSS J145049.18+100638.0 I have never seen before. I did a eyepiece drawing below that shows the five galaxies that I observed.

Next time you are out under a clear dark spring sky be sure to track down the new found giant of the cosmos and as always,

"GIVE IT A GO AND LET US KNOW"

GOOD LUCK AND GREAT VIEWING!
