Object data of NGC3239 |
|||
| Object type: | Galaxy (Irr) | ||
| Size: | 4.5' x 2.4' | ||
| Magnitude: | 11.7 mag | ||
| Constellation: | Leo | ||
| Distance: | 25 Mio Ly | ||
| Notes: |
NGC 3239 (Arp 263) is an irregular galaxy in a distance of 25 Mio light
years. The galaxy as we see it now is most likely the result of a galaxy
merger. It shows a possible remnant of disk structure, tidal tails of stars
(even though there are no nearby companions), many star-forming regions
including a giant one, and young blue star clusters, indicating recent star
formation. The object identification image shows besides NGC 3239 many CGCG galaxies, the distant galaxy cluster WHL J102522.5+170225 (z=0.269, 3.0 billion light years) and the extremely distant quasar SDSS J102530.36+170852.9 (z=4.09, 11.8 billion years light travel time). |
