IC 2900 (= PGC 1424467)
Discovered (Mar 27, 1906) by
Max Wolf (7-272)
A magnitude 16.9 spiral galaxy (type SBb?) in Leo (RA 11 31 29.6, Dec +13 10 04)
Based on a recessional velocity of 25190 km/sec, a straightforward calculation indicates that IC 2900 is about 1.15 billion light years away. However, for objects at that distance we need to take the expansion of the Universe during their light-travel time into account. Doing that shows that the galaxy was about 1.05 billion light years away at the time the light by which we see it was emitted, about 1.1 billion years ago (the difference between the two numbers being due to the expansion of the Universe during that interval). Given that and its apparent size of 0.3 by 0.25 arcmins, the galaxy is about 90 thousand light years across.

IC 2944
Discovered (May 5, 1904) by
Royal Frost (789)
A magnitude 4(?) emission nebula in Centaurus (RA 11 35 47.3, Dec -63 01 11)
About 40 by 20 arcmin apparent size, with 3rd magnitude λ Centauri generally considered its center. Sometimes listed as the Running Chicken Nebula, but that name is also assigned to the much larger IC 2948, and there is no obvious reason for either nebula to be associated with a fowl of any sort, so which if either deserves the apparently useless appellation is unclear. (Note: Thackeray's Globules, often stated as being in IC 2944, appear to actually be in IC 2948, so for now see that entry for images of them; this issue to be dealt with in the next iteration of this page.)

IC 2948
Discovered (May 5, 1904) by
Royal Frost (790)
Some references list IC 2948 as the Running Chicken Nebula, but other sources assign that name to IC 2944, and there is no obvious reason for either nebula to be associated with a fowl of any sort, so which if either deserves the apparently useless appellation is unclear. Dark globules near the center of IC 2948 are examples of "Bok globules", but are called Thackeray's Globules, after their discoverer in this particular nebula. There appears to be some confusion about which part of this and its companion (IC 2944) is which. The HST image below is labeled as being in IC 2944 in every reference I've seen, but the region is actually near the center of IC 2948. This confusion will hopefully be resolved when I post the history of the IC listing in the next iteration of this page. Apparent size 45 by 40 arcmin?
