Four galaxies are smashed together in a space the size of the Milky Way

This country of the universe is known as Seyfert ’s Sextet , although there are really only four galaxies engaged in this particular cosmic sward warfare . First spotted by uranologist Carl Keenan Seyfert , these tightly packed galaxies symbolize the most thick mathematical group ever describe , as the space they occupy would barely be enough to fit in our entire galaxy .

This finical icon comes courtesy of the Hubble Telescope . The practiced common people over at NASA explain just what ’s go on in the persona :

The sextet actually moderate only four interact galaxies , though . Near the center of this Hubble Space Telescope flick , the small look - on spiral galaxy lies in the distant background and seem only by chance aligned with the principal group . Also , the spectacular abridgment on the upper left hand is likely not a disjoined coltsfoot at all , but a tidal tail of stars flung out by the galaxies ’ gravitative interactions . About 190 million light - years off , the interacting coltsfoot are tightly packed into a neighborhood around 100,000 light - geezerhood across , corresponding to the size of it of our own Milky Way galaxy , make this one of the densest known galaxy group . bind by gravity , the close - knit group may coalesce into a single declamatory wandflower over the next few billion class .

And here’ssome additional insightfrom the National Optical Astronomy Observatory :

Seyfert ’s Sextet , a grouping of ( as the name implies ) six galaxies in the constellation Serpens , is an interesting example of a discordant redshift group . Five of the phallus show very similar redshift , from 4000 to 4500 km / s , while the 5th is assess at nearly 20000 kilometre / s. Conventional wisdom argues that this is a chance projection of a distant background galaxy : some would have otherwise and require a complete rethink of modern cosmology and the instauration of completely new physics .

And on that not at all disquieting note , I ’ll allow you to your holiday festivities .
