Typical DSO survey in Celestia. Celestia versions 1.6.3 and under display the Hipparcos Catalogue (HIP) of 118,322 stars and a compiled catalogue of galaxies, while version 1.7.0 includes stars from the Tycho-2 Catalogue alongside the Hipparcos stars, with some data from Gaia, increasing the star count to over 2 million.

In the latest JWST image, you can see the more distant stars through the black bubble-like windows, giving the image a 3D effect. Vast distances most often separate galaxies from each other.
Stars! does not run directly on the 64-bit version of Windows XP, Windows Vista or Windows 7, which cannot run 16-bit software. However, it can be played on a virtual machine-like Virtual Windows XP on Windows 7, [5] or in VirtualPC on earlier 32-bit versions of windows. Another alternative is VirtualBox.
NGC 128 is the largest member, and the namesake of, the NGC 128 group which also includes the galaxies NGC 127 and NGC 130.NGC 128 has a strong tidal bridge with NGC 127 and there is evidence of interaction between all three galaxies in the group.
NGC 891 looks as the Milky Way would look like when viewed edge-on (some astronomers have even noted how similar to NGC 891 our galaxy looks as seen from the Southern Hemisphere [9]) and, in fact, both galaxies are considered very similar in terms of luminosity and size; [10] studies of the dynamics of its molecular hydrogen have also proven the likely presence of a central bar.

Arp 273 is a pair of interacting galaxies, 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in 1966. [5] The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy. [6]
The average mass of these clusters is around 200,000 solar masses, hence the starburst core is a very energetic and high-density environment. [7] Throughout the galaxy's center, young stars are being born 10 times faster than they are inside the entire Milky Way Galaxy. [18] In the core of M82, the active starburst region spans a diameter of ...
An ultraviolet-to-infrared study by Eufrasio, et al. (2013), using data from GALEX, Spitzer, and other resources found that the interaction between the two galaxies appears to have triggered significant star formation in the northeastern arm of NGC 6872 beginning about 130 thousand light-years (40 kpc) from its nucleus.
